    Drug Safety Alert: Risk of Kidney Injury and Death due to Hydroxyethyl-Starch Solutions for Infusion.

    Asad Ullah Pharmacovigilance, Regulatory Updates, Safety Alerts

    Drug Safety Alert

    Update from Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of Pakistan

    Date:29th of November, 2022
    Target Audience:• Manufacturers and importers of hydroxyethyl-starch solutions for infusion.
    • Healthcare Professionals; and
    • Patients, consumers or caregivers.
    Background:The Pharmacovigilance Risk Assessment Committee (PRAC) of the European Medicine Agency (EMA) on 11th February, 2022 recommended that the market authorization of hydroxyethyl-starch (HES) solutions for infusion should be suspended across the European Union. These solutions for infusion products are indicated as an addition to other treatments for plasma volume replacement following acute (sudden) blood loss.
    The safety of these solutions for infusion was reviewed in 2013, and a number of restrictions and measures to minimise the risk of kidney injury and death in certain patients (those critically ill, with burn injuries or with sepsis, a bacterial infection in the blood) were put in place at that time.

    Likewise, as a result of a third review conducted in 2018, the use of HES solutions for infusion was further restricted to only accredited hospitals, and healthcare professionals prescribing or administering the medicines had to be trained in their appropriate use. In addition, further warnings were introduced to remind healthcare professionals that these medicines must not be used in patients with sepsis or kidney impairment or in other vulnerable patients such as the critically ill in order to ensure these solutions for infusion were not used in patients who were at increased risk of harm. Market authorization holders of HES solutions for infusion were also requested to conduct a drug utilization study to check that the restrictions were adhered to in clinical practice.

    The PRAC of the EMA accordingly reviewed the results of the study, which show that HES solutions for infusion are still being used outside the recommendations included in the product information and concluded that the further restrictions introduced in 2018 have not sufficiently ensured that the medicines are used safely and that HES solutions were continually used in certain groups of patients in whom serious harm has been demonstrated. In view of the serious risks that certain patient populations were still exposed to, the PRAC recommended the suspension of the marketing authorizations for HES solutions for infusion in the European Union. Accordingly, the European Commission on 24th May, 2022 issued a legal decision confirming the suspension of the market authorization of HES solution for infusion.
    Therapeutic Good(s) Affected:Name: Hydroxyethyl-Starch solutions for infusion.

    These solutions for infusion products are indicated as an addition to other treatments for plasma volume replacement following acute (sudden) blood loss.
    Action in PakistanAccordingly, the case of the risk of kidney injury and death due to hydroxyethyl-starch solutions for infusion was discussed in the 1st meeting of the Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of the National Pharmacovigilance Centre (NPC), Division of Pharmacy Services, Drug Regulatory Authority of Pakistan (DRAP). The PRAEC-DRAP after detailed deliberation and discussion and as per Rule 10 (1) (h) (v) of Pharmacovigilance Rules, 2022 (reliance mechanism) decided to recommend to the Registration Board of the DRAP to suspend the registration of Hydroxyethyl-Starch (HES) solutions in Pakistan subject to the availability of alternative treatment options.
    Advice for healthcare professionals:Healthcare professionals are informed that the National Pharmacovigilance Centre, DRAP is working with the Registration Board and manufacturers/importers of hydroxyethyl-starch solutions for infusion to suspend the registration of these solutions in Pakistan. Therefore, healthcare professionals are reminded that there are alternative solutions for infusion available in the Pakistani market for the treatment of plasma volume replacement following acute (sudden) blood loss and the same must be considered as the treatment in these conditions.
    Advice for patients:Patients are informed that the National Pharmacovigilance Centre, DRAP is working with the Registration Board and manufacturers/importers of hydroxyethyl-starch solutions for infusion to suspend the registration of these solutions in Pakistan. Therefore, talk with your doctor before initiation of treatment with those solutions as alternative treatment options are available in the market.
    Guidelines for reporting Adverse Drug Reactions (ADRs):Both healthcare professionals and patients are requested to report any suspected Adverse Drug Reaction (ADR) to National Pharmacovigilance Centre, Drug Regulatory Authority of Pakistan through Med Vigilance E-Reporting system available on DRAP website.

      Drug Safety Alert: Increased Risk of Cardiovascular Events with Co-administration and Interaction Between Hydroxychloroquine or Chloroquine, and Macrolide Antibiotics

      Asad Ullah Safety Alerts

      Drug Safety Alert

      Update from Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of Pakistan

      Date:29th of November, 2022
      Target Audience:• Manufacturers and importers of hydroxychloroquine or chloroquine, and systemic macrolide antibiotics;
      • Healthcare professionals; and
      • Patients, consumers or caregivers.
      Background:The MHRA on 15th February, 2022 announced that the product information for hydroxychloroquine, chloroquine and macrolide antibiotics (azithromycin, erythromycin or clarithromycin) will be revised to include the increased risk of cardiovascular events and cardiovascular mortality if hydroxychloroquine or chloroquine is taken with a macrolide-antibiotic. A review was conducted by the Pharmacovigilance Expert Advisory Group of the Commission on Human Medicines following the results of a retrospective observational study which shows that co-administration of azithromycin with hydroxychloroquine in patients with rheumatoid arthritis is associated with an increased risk of cardiovascular events (including angina or chest pain and heart failure) and cardiovascular mortality.

      It was recommended in the review that the product information for hydroxychloroquine and systemic azithromycin medicines should be amended to include new warnings and advice on these risks. Owing to the similar safety profiles, the risks with concurrent use of hydroxychloroquine and azithromycin were considered to apply to the concurrent use of hydroxychloroquine and other systemic macrolide antibiotics (clarithromycin or erythromycin) and to the use of chloroquine with systemic macrolide antibiotics. Therefore, the review recommended that similar warnings should also be added to the product information for chloroquine and for systemic clarithromycin or erythromycin. However, these warnings were not being introduced for topical macrolide products (which are indicated for conjunctivitis or acne).

      The MHRA also reminded the healthcare professionals that the product information for hydroxychloroquine and chloroquine already contains warnings about cases of cardiomyopathy resulting in cardiac failure, in some cases with fatal outcomes. It was also informed that evidence suggests both hydroxychloroquine and chloroquine can prolong the QT interval, especially in overdose or when used in combination with other medicines with the potential to induce cardiac arrhythmias. Likewise, warnings are also in place across the product information for azithromycin, clarithromycin, and erythromycin to use caution in patients with a history of QT interval prolongation or in patients receiving a medicine known to cause QT prolongation. Although the mechanism of the observed effects was not examined in detail by the study, it was proposed that events could have been caused by cumulative effects of hydroxychloroquine and azithromycin on the QT interval, potentiating arrhythmias and cardiac death, or through other additive cardiotoxic effects more generally.
      Therapeutic Good(s) Affected:Name of Drugs: (i)Hydroxychloroquine,
      (ii) Chloroquine; and
      (iii) Systemic macrolide antibiotics (not topical).

      Hydroxychloroquine is indicated for the treatment of rheumatoid arthritis, systemic lupus erythematosus, and dermatological conditions aggravated by sunlight. Chloroquine is indicated for malaria prophylaxis or treatment and other indications. Macrolide antibiotics such as erythromycin, clarithromycin and azithromycin are used to manage and treat various bacterial infections like pneumonia, sinusitis, pharyngitis and tonsillitis etc.
      Action in PakistanAccordingly, the case of risk of cardiovascular events with co-administration and interaction between hydroxychloroquine or chloroquine, and macrolide antibiotics was discussed in the 1st meeting of the Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of the National Pharmacovigilance Centre (NPC), Division of Pharmacy Services, Drug Regulatory Authority of Pakistan (DRAP). The PRAEC-DRAP after discussion decided as per Rule 10 (1) (h) (iv) and (vi) of Pharmacovigilance Rules, 2022 (reliance mechanism) to update prescribing information (warning and interaction sections) of hydroxychloroquine, chloroquine and macrolide antibiotics (azithromycin, erythromycin or clarithromycin excluding topical macrolides) about the potential interaction of increased risk of cardiovascular events and cardiovascular mortality if hydroxychloroquine or chloroquine is taken with a macrolide-antibiotic.
      Advice for healthcare professionals:Healthcare professionals are informed that an observational study has shown that co-administration of azithromycin with hydroxychloroquine in patients with rheumatoid arthritis is associated with an increased risk of cardiovascular events (including angina or chest pain and heart failure) and cardiovascular mortality. Therefore, carefully consider the benefits and risks before prescribing systemic azithromycin or other systemic macrolide antibiotics (erythromycin or clarithromycin) to patients being treated with hydroxychloroquine or chloroquine. If there is a clinical need to prescribe systemic macrolide antibiotics with hydroxychloroquine or chloroquine, use caution in patients with risk factors for cardiac events.
      Advice for patients:Patients are informed that some antibiotics (known as macrolides) taken by mouth or given as an injection at the same as hydroxychloroquine or chloroquine have been associated with an increased risk of side effects that affect the heart. Seek urgent medical help if you have any signs of problems with your heart (for example, palpitation, fainting, chest pain, or unexplained breathlessness).
      Guidelines for reporting Adverse Drug Reactions (ADRs):Both healthcare professionals and patients are requested to report any suspected Adverse Drug Reaction (ADR) to National Pharmacovigilance Centre, Drug Regulatory Authority of Pakistan through Med Vigilance E-Reporting system available on DRAP website.
      Similarly, ADRs can also be reported through MedSafety App that is available for download from App store (for iOS devices) and Google Play (for Android devices).

        Drug Safety Alert: Risk of Major Congenital Malformations with Pregabalin

        Asad Ullah Regulatory Updates, Safety Alerts

        Drug Safety Alert

        Update from Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of Pakistan

        Date:29th of November, 2022
        Target Audience:• Manufacturers and importers of Pregabalin;
        • Healthcare Professionals; and
        • Patients, consumers or caregivers.
        Background:The Medicine and Healthcare Products Regulatory Agency (MHRA) of the United Kingdom on 19th April, 2022 announced that the product information for pregabalin will be updated to include information from a new study which has suggested pregabalin may slightly increase the risk of major congenital malformations if used in pregnancy. The MHRA reviewed the results of a Nordic observational study that consisted of 2,700 pregnancies exposed to pregabalin in the first trimester, alongside a recent European review which had the same conclusions. The study showed a higher prevalence of major congenital malformations in the babies (live or stillborn) exposed to pregabalin in the first trimester of pregnancy compared with those not exposed to pregabalin or any other antiepileptic drug.
        The review concluded that pregabalin’s use during the first trimester of pregnancy may cause a slight increase in the risk of major congenital malformations in the unborn child. Furthermore, the Health Products Regulatory Authority (HPRA) of Ireland back in February 2022 also recommended that product information of Pregabalin along with other anti-epileptic drugs be updated based on the evidence of risks associated with in-utero exposure to these drugs. The product information of pregabalin continues to advise that effective contraception should be used during treatment and that use in pregnancy should be avoided unless it is necessary.
        Therapeutic Good(s) Affected:Name of Drug: Pregabalin

        Pregabalin is indicated for the treatment of peripheral and central neuropathic pain in adults, as adjunctive therapy in adults with partial seizures with or without secondary generalization, and for generalized anxiety disorder in adults.
        Action in PakistanAccordingly, the case of the risk of major congenital malformations with Pregabalin was discussed in the 1st meeting of the Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of the National Pharmacovigilance Centre (NPC), Division of Pharmacy Services, Drug Regulatory Authority of Pakistan (DRAP). The PRAEC after detailed deliberation and discussion decided as per Rule 10 (1) (h) (iv) and (vi) of Pharmacovigilance Rules, 2022 (reliance mechanism) to update prescribing information of Pregabalin to include information from a new study that pregabalin may slightly increase the risk of major congenital malformations if used in pregnancy and include advise on effective contraception during treatment in pregnancy.
        Advice for healthcare professionals:A new study has demonstrated that pregabalin may slightly increase the risk of major congenital malformations if used in first trimester of pregnancy. Therefore, healthcare professionals should provide counselling to the patients on potential risks to an unborn baby with pregabalin and also on the need to use effective contraception during the treatment. Healthcare professionals are also advised to continue to avoid the use of pregabalin during pregnancy unless clearly necessary and only if the benefit to the patient clearly outweigh the potential risk to the fetus. In case where the benefit outweighs the risk, and it is clearly necessary that pregabalin has to used during the pregnancy, then the lowest effective dose should be used.
        Advice for patients:Patients are advised to talk to their doctors before initiation of treatment with Pregabalin and discuss the benefit-risk of the medicine, particularly related to their case. Patients are also advised to talk with their healthcare professionals and use an appropriate contraception method during the treatment with Pregabalin to avoid pregnancy.
        Guidelines for reporting Adverse Drug Reactions (ADRs):Both healthcare professionals and patients are requested to report any suspected Adverse Drug Reaction (ADR) to National Pharmacovigilance Centre, Drug Regulatory Authority of Pakistan through Med Vigilance E-Reporting system available on DRAP website.
        Similarly, ADRs can also be reported through MedSafety App that is available for download from App store (for iOS devices) and Google Play (for Android devices).

          Asad Ullah Safety Alerts, Safety Communication, Safety Info

          Drug Safety Alert

          Update from Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of Pakistan

          Date:23rd of November, 2022
          Target Audience:• Manufacturers and importers of metformin and metformin-containing medicines;
          • Healthcare Professionals; and
          • Patients, consumers or caregivers.
          Background:The Medicine and Healthcare Products Regulatory Agency (MHRA) of the United Kingdom on 20th June, 2022 through a drug safety update informed that decreased vitamin B12 levels, or vitamin B12 deficiency, is now considered a common side effect in patients on metformin treatment, especially in those receiving a higher dose or longer treatment duration and in those with existing risk factors. It was informed that the known adverse drug reaction of vitamin B12 deficiency was recently reviewed for the brand leader Glucophage (Metformin) within Europe with input from the MHRA. After this review, the MHRA agreed that the product information for patients and healthcare professionals for medicines containing metformin should be updated to state that vitamin B12 deficiency is a common adverse drug reaction, and may affect up to 1 in 10 people who take it. The product information for other medicines containing metformin will also be updated including fixed-dose combination products containing metformin.
          The product information has also been updated to note that the risk of this adverse reaction occurring increases with increasing metformin dose and treatment duration and in patients with risk factors known to cause vitamin B12 deficiency such as:

          i. baseline vitamin B12 levels at the lower end of the normal range;
          ii. conditions associated with reduced vitamin B12 absorption (such as elderly people and those with gastrointestinal disorders such as total or partial gastrectomy, Crohn’s disease and other bowel inflammatory disorders, or autoimmune conditions);
          iii. diets with reduced sources of vitamin B12 (such as strict vegan and some vegetarian diets);
          iv. concomitant medications that are known to impair vitamin B12 absorption (including proton pump inhibitors or colchicine); and
          v. genetic predisposition to vitamin B12 deficiency, such as intrinsic factor receptor deficiency (Imerslund-Gräsbeck syndrome) and transcobalamin II deficiency.
          Therapeutic Good(s) Affected:Metformin and metformin-containing medicines
          Metformin is a medicine authorized to treat type 2 diabetes mellitus and to help prevent type 2 diabetes in patients at high risk of developing it.
          Action in PakistanAccordingly, the case of the risk of reduced vitamin B12 level with metformin and metformin-containing medicines was discussed in the 1st meeting of the Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of the National Pharmacovigilance Centre (NPC), Division of Pharmacy Services, Drug Regulatory Authority of Pakistan (DRAP). The PRAEC after discussion decided as per Rule 10 (1) (h) (iv) of Pharmacovigilance Rules, 2022 (reliance mechanism) to update prescribing information of Metformin and other medicines containing Metformin to state that vitamin B12 deficiency is an adverse drug reaction with Metformin use and the risk of this adverse reaction occurrence increases with increasing metformin dose and treatment duration and in patients with risk factors known to cause vitamin B12 deficiency.
          Advice for healthcare professionals:Healthcare professionals are informed that metformin can commonly reduce vitamin B12 levels in patients, which may lead to vitamin B12 deficiency. The risk of low vitamin B12 levels increases with higher metformin doses, longer treatment duration, and in patients with risk factors for vitamin B12 deficiency. Healthcare professionals are advised to test vitamin B12 serum levels if deficiency is suspected and also consider periodic vitamin B12 monitoring in patients with risk factors of vitamin B12 deficiency.
          Advice for patients:Patients who have low vitamin B12 levels or elderly patients and those with gastrointestinal disorders such as total or partial gastrectomy, Crohn’s disease and other bowel inflammatory disorders, or autoimmune conditions or those patients who have a genetic predisposition to vitamin B12 deficiency are advised to talk to their healthcare professionals during the treatment with metformin and metformin containing medicines.
          Guidelines for reporting Adverse Drug Reactions (ADRs):Both healthcare professionals and patients are requested to report any suspected Adverse Drug Reaction (ADR) to National Pharmacovigilance Centre, Drug Regulatory Authority of Pakistan through Med Vigilance E-Reporting system available on DRAP website.

            • Healthcare Professionals; and
            • Patients, consumers or caregivers.
            Background:The National Pharmaceutical Regulatory Agency (NPRA) of Malaysia in April, 2021 announced that the product information for Atezolizumab (Tecentriq®) has been updated to include the risk of severe cutaneous adverse reactions (SCAR). Based on analysis from the company’s global safety data of 99 cases of SCARs identified globally, of which 36 cases were confirmed by histopathology or specialist diagnosis.

            Similarly, the Medicines and Healthcare Products Regulatory Agency (MHRA) in June, 2021 also announced that the product information for Atezolizumab (Tecentriq®) has been updated to include information about the risk of severe cutaneous adverse reactions (SCARs), which includes Stevens-Johnsons syndrome (SJS) and Toxic Epidermal Necrolysis (TEN). SCARs were previously known to be potentially associated with the use of Atezolizumab. A review of safety data for Atezolizumab and the risk of SCARs was recently completed in Europe. Based on this review SCARs are an identified risk for Atezolizumab. Also, other products used for cancers in the same class as atezolizumab, including cemiplimab, ipilimumab, nivolumab and pembrolizumab list SCARs as possible adverse effects in the Summary of Product Characteristics (SmPC). In addition, Direct Healthcare Professional Communication (DHPC) were also issued by the manufacturers in New Zealand and European Medicine Agency back in November, 2020.

            SCARs are a heterogeneous group of delayed hypersensitivity reactions. These events mainly consist of acute generalised exanthematous pustulosis (AGEP), Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug rash with eosinophilia and systemic symptoms (DRESS) and can be potentially life-threatening, and lead to severe, potentially chronic sequelae.
            Therapeutic Good(s) Affected:Atezolizumab

            Atezolizumab is an immunostimulatory drug indicated to treat non-small cell lung cancer, small cell lung cancer, hepatocellular carcinoma, urothelial carcinoma and triple-negative breast cancer.
            Action in PakistanAccordingly, the case of risk of severe cutaneous adverse reactions (SCARs) with Atezolizumab
            was discussed in the 1st meeting of the Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of the National Pharmacovigilance Centre (NPC), Division of Pharmacy Services, Drug Regulatory Authority of Pakistan (DRAP). The PRAEC after deliberation decided as per Rule 10 (1) (h) (iv) of Pharmacovigilance Rules, 2022 (reliance mechanism) to update prescribing information of Atezolizumab (Tecentriq®) to include the risk of severe cutaneous adverse reactions (SCAR) including Stevens-Johnsons Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN). Furthermore, it was decided that registration holders should issue direct healthcare professional communication in this regard.
            Advice for healthcare professionals:Healthcare professionals are informed that severe cutaneous adverse reactions (SCARs), including cases of Steven-Johnsons Syndrome(SJS) and Toxic Epidermal Necrolysis (TEN), have been reported in patients treated with immune-stimulatory anti-cancer drugs including Atezolizumab. Advise patients to seek urgent medical assistance if severe skin reactions occur. Also, monitor patients for signs and symptoms of severe skin reactions and exclude other causes. If a SCAR is suspected, treatment should be withheld and patients should be referred to a specialist for diagnosis and treatment. If SJS or TEN is confirmed or in case of any grade 4 SCAR, permanently discontinue treatment with immune stimulatory drugs.
            Advice for patients:Patients are advised to be vigilant for the signs of severe skin reactions with the use of Atezolizumab and to seek urgent medical advice if they occur.
            Guidelines for reporting Adverse Drug Reactions (ADRs):Both healthcare professionals and patients are requested to report any suspected Adverse Drug Reaction (ADR) to National Pharmacovigilance Centre, Drug Regulatory Authority of Pakistan through Med Vigilance E-Reporting system available on DRAP website.

              Drug Safety Update: Risk of Hypothyroidism in Babies and Young Children with Iodinated Contrast Media (ICM) Injections

              Asad Ullah Safety Alerts, Safety Communication, Safety Info

              Drug Safety Alert

              Update from Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of Pakistan

              Date:19th of November 2022
              Target Audience:• Manufacturers and importers of Iodinated contrast media (ICM) injections such as iohexol, iopromide and iodixanol etc;
              • Healthcare Professionals; and
              • Patients, consumers or caregivers.
              Background:On 30th March, 2022, the United States Food and Drug Administration (US-FDA) through a Drug Safety Communication informed that they have approved a new warning to the prescribing information for the entire class of iodinated contrast media (ICM) injections and monitoring recommendations for children 3 years or younger. The warning describes the risk of an underactive thyroid or a temporary decrease in thyroid hormone levels. These risks and recommendations pertain to ICM given as an injection through an artery or vein. Newborns, particularly those born premature, and children in their first 3 years with underlying conditions such as heart issues may be at higher risk for problems with the thyroid. It was informed that the agency first alerted the public about cases of underactive thyroid in infants receiving ICM back in 2015 and now six new research studies evaluating this risk have been published. The FDA has concluded based on their review of the published studies that there is compelling evidence of a significant risk for an underactive thyroid or a temporary decrease in thyroid hormone levels in newborns and children through 3 years after exposure to ICM. Back in December 2017, the Medicines and Medical Devices Safety Authority (Medsafe) of New Zealand also requested that data sheets for iodine-containing contrast agents (ICAs) to be updated with information on the risk of hypothyroidism, particularly in neonates and should include advice on thyroid monitoring.
              Therapeutic Goods Affected:Iodinated contrast media (ICM) injections such as iohexol, iopromide and iodixanol etc.

              ICM are drugs containing iodine that are given to patients to enhance the ability to see blood vessels, organs, and tissues on medical images such as X-rays or computed tomography (CT) scans, thus helping healthcare professionals to diagnose potential problems. Examples include iohexol (Omnipaque), iopromide (Ultravist 300, 370) and iodixanol (Visipaque 270, 320) etc. Common side effects associated with ICM include flushing in the face, nausea or vomiting, mild itchiness, and skin rash.
              Action in PakistanAccordingly, the case of the risk of hypothyroidism in babies and young children with iodinated contrast media (ICM) injections was discussed in the 1st meeting of the Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of the National Pharmacovigilance Centre (NPC), Division of Pharmacy Services, Drug Regulatory Authority of Pakistan (DRAP). The PRAEC after detailed deliberation and discussion decided as per Rule 10 (1) (h) (iv) of Pharmacovigilance Rules, 2022 (reliance mechanism) to update the warning and precaution section of the prescribing information of the entire class of iodinated contrast media (ICM) that are used for radiological purposes to include risks of an underactive thyroid or a temporary decrease in thyroid hormone levels in children 3 years or younger i.e newborns, particularly those born premature, and children in their first 3 years with underlying conditions such as heart issues etc.
              Advice for healthcare professionals:Healthcare professionals are advised to perform appropriate monitoring of patients from birth through 3 years for the possibility of hypothyroidism or a temporary decrease in thyroid hormone levels following exposure to iodinated contrast media (ICM) injections. Healthcare professionals are also advised to consider evaluating thyroid function within 3 weeks, especially in term and preterm neonates and children with some underlying conditions. If thyroid dysfunction is detected, it should be properly treated and monitored as clinically needed to avoid future cognitive and other developmental disabilities. Increased-risk pediatric patients include those who are newborns or have very low birth weight, prematurity, or the presence of cardiac or other conditions such as those requiring care in neonatal or pediatric intensive care units. Patients with cardiac conditions may be at the greatest risk since they often require high doses of contrast during invasive cardiac procedures. These increased-risk pediatric patients require close monitoring.
              Advice for patients:Parents and caregivers of a child below 3 years and receiving ICM injections should talk with healthcare professionals for additional information. If the child is a newborn, has very low birth weight, was premature, has a heart condition, or was admitted to a neonatal or pediatric intensive care unit, they may be at higher risk of developing underactive thyroid or a temporary decrease in thyroid hormone levels. Babies & young children typically do not show any visible signs of thyroid problems & may need to be monitored by their healthcare professionals after receiving ICM.
              Guidelines for reporting Adverse Drug Reactions (ADRs):Both healthcare professionals and patients are requested to report any suspected adverse drug reaction (ADRs) to National Pharmacovigilance Centre, Drug Regulatory Authority of Pakistan through Med Vigilance E-Reporting system available on DRAP website.
              Similarly, ADRs can also be reported through MedSafety App that is available for download from App store (for iOS devices) and Google Play (for Android devices).

                Drug Safety Update; PRAEC issued a Safety Alert on Risk of Sinus Bradycardia with Remdesivir

                Asad Ullah Safety Alerts, Safety Communication, Safety Info

                Drug Safety Alert

                Update from Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of Pakistan

                Date:21st of November 2022
                Target Audience:• Manufacturers and importers of Remdesivir;
                • Healthcare Professionals; and
                • Patients, consumers or caregivers.
                BackgroundHealth Canada in August, 2021 announced that it will work with the manufacturer of Remdesivir to update the product information to include a warning on the potential risk of sinus bradycardia. Health Canada assessed case reports of sinus bradycardia in patients receiving Remdesivir in their database and in the literature and concluded that a link between the use of Remdesivir and the risk of sinus bradycardia is possible.

                Previously, in June 2021, the Pharmacovigilance Risk Assessment Committee (PRAC) of the European Medicine Agency (EMA) recommended a change to the product information for Remdesivir (Veklury®) to include sinus bradycardia as an adverse drug reaction. The PRAC reviewed available data on rare reported cases of bradycardia in patients treated with Remdesivir as well as data from clinical trials and the scientific literature. The PRAC concluded that a causal relationship between the use of Remdesivir and the event is reasonably possible and recommended the revision of the product information. The majority of the events of sinus bradycardia resolved a few days after the treatment with Remdesivir was discontinued.

                Sinus bradycardia occurs when the heart beats slower than normal. Sinus bradycardia can very rarely cause symptoms, such as dizziness, tiredness, shortness of breath, and chest discomfort.
                Action in PakistanAccordingly, the case of the risk of sinus bradycardia with Remdesivir was discussed in the 1st meeting of the Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of the National Pharmacovigilance Centre (NPC), Division of Pharmacy Services, Drug Regulatory Authority of Pakistan (DRAP). The PRAEC after discussion decided as per Rule 10 (1) (h) (iv) of Pharmacovigilance Rules, 2022 (reliance mechanism) to update the prescribing information (warning & adverse drug reactions sections) of Remdesivir to include the potential risk of sinus bradycardia.

                  Drug Safety Alert

                  Update from Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of Pakistan

                  Date:18th of November 2022
                  Target Audience:• Manufacturers and importers of Remdesivir;
                  • Healthcare Professionals; and
                  • Patients, consumers or caregivers.
                  Problem or Issue:The National Pharmacovigilance Centre (NPC), Division of Pharmacy Services, Drug Regulatory Authority of Pakistan (DRAP) received a cluster of three serious (life-threatening) adverse drug reaction reports from a hospital with Inj Remdesivir (100mg/20ml). The events of tachycardia, dyspnoea, chills and pyrexia were noted after the use of Remdesivir through an intravenous drip for COVID-19 Pneumonia, with a time to onset of 0 days. The causality assessment of all three cases was performed by the Causality Assessment Group of the NPC and classified that all three cases have a possible relationship with drug intake. However, at the same time, the NPC also carried out the quality testing of the suspected batch of Remdesivir, which was declared of standard quality with regard to the tests performed by the Central Drugs Laboratory, DRAP, Karachi. The NPC accordingly labelled it as a potential signal of infusion-related hypersensitivity reactions with the injection of Remdesivir.
                  Further assessment was also carried out at NPC-DRAP, where the signal was confirmed from the approved label of the United States Food and Drugs Administration (US-FDA) and Summary of Product Characteristics (SmPC) of Medicine and Health Products Agency (MHRA) of the United Kingdom. There was also significant disproportionality and potential association of Remdesivir with infusion-related hypersensitivity reactions as per the statistical tools available in VigiLyze of the Uppsala Monitoring Centre.

                  The case was discussed in the 1st meeting of the Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of the NPC, DRAP and decides as to update the prescribing information/ safety specification/ label of Remdesivir injection with the inclusion of information related to infusion-related hypersensitivity reactions and its monitoring in the warning and precaution sections. Furthermore, it was also decided that all registration holders should introduce educational training for healthcare professionals on proper preparation, administration and flow rate of Remdesivir, and monitoring of patients.

                  Advice / Directions for for Registration HolderRegistration holders of Remdesivir injection are hereby advised/directed to update the prescribing information/safety specification/ label of Remdesivir with the inclusion of information related to infusion-related hypersensitivity reactions and its monitoring in the warning and precaution sections. Furthermore, registration holders should also introduce educational training for healthcare professionals on proper preparation, administration and flow rate of Remdesivir, and monitoring of patients.
                  Advice for healthcare professionals:Healthcare professionals are informed that the Pharmacovigilance Risk Assessment Expert Committee (PRAEC) of the DRAP has recommended updating the prescribing information/ safety specification/ label of Remdesivir injection with the inclusion of information related to infusion-related hypersensitivity reactions and its monitoring in the warning and precaution sections, and is working with registration holders in this regard.
                  Healthcare professionals are also informed that the signs and symptoms of infusion-related hypersensitivity reactions may include hypotension, hypertension, tachycardia, bradycardia, hypoxia, fever, dyspnea, wheezing, angioedema, rash, nausea, diaphoresis, and shivering, which have been observed during and following administration of Remdesivir injection which mostly occurred within one hour. Therefore, slower infusion rates with a maximum infusion time of up to 120 minutes should be considered to potentially prevent these signs and symptoms. Furthermore, monitor patients during infusion and observe patients for at least one hour after the infusion is completed for signs and symptoms of hypersensitivity as clinically appropriate. If signs and symptoms of a clinically significant hypersensitivity reaction occur, immediately discontinue the administration of Remdesivir injection and initiate appropriate treatment.
                  Advice for patients:Patients are informed that hypersensitivity reactions including infusion-related reactions have been observed during and following the administration of Remdesivir injection. Immediately call your doctor if you experience signs and symptoms such as hypotension, hypertension, tachycardia, bradycardia, hypoxia, fever, dyspnea, wheezing, angioedema, rash, nausea, diaphoresis, and shivering after administration of Remdesivir injection.
