The decision applies to all registration holders of Famotidine 10mg/5ml and 40mg/5ml Liquid Suspension except those who have obtained interim relief from the Hon’ble Lahore High Court, Lahore or who have registration of Famotidine 40mg/5ml Dry Suspension.
Background:
The Registration Board in its 250th meeting held on 10th July, 2015 had decided that Famotidine 10mg/5ml Suspension is not registered in any reference regulatory agencies and the internationally available formulation is a dry powder for suspension in the strength of 40 mg/ 5 ml and asked applicants to revise their formulation as per innovator (new registration application With complete fee) within six months if the manufacturing facility is approved by Central Licensing Board.

However, DRAP’s Authority in its 70th meeting held on 05th Sep 2019 decided that “For formulations containing “drugs” which were previously registered by the Registration Board and have proof of availability and prescription of last 10 years but are not available in the Reference Regulatory Authorities shall continue to be considered/ registered as drugs until and unless withdrawn on Safety, Efficacy and Quality reasons”.

Accordingly, Registration Board in its 296th meeting held 8th-10th Sep, 2020 decided that “since all such formulations which are not approved by the Reference Regulatory Authorities; the safety and efficacy profile cannot be established in the absence of a well-established system for reporting of adverse events, so a reference shall be forwarded to DRAP’s Authority with the request to review the decision taken in its 70th meeting held on 05-09-2019. In this regard, PE&R Division shall prepare a comprehensive document/agenda for consideration of Authority”. It was also decided that “For all those formulations which are registered/ applied in strengths, different from those approved by reference regulatory authorities, the registration holders/ applicants shall standardize their formulations (by submitting registration application with requisite fee, provided that the firm did not have same registration) in line with those approved by reference regulatory authorities. Meanwhile, the policy of reliance on reference regulatory authorities was approved by the Authority in its 73rd meeting held on 06-11-2019. Subsequently, the registration board in its 313th meetings, dated 16-18th Nov, 2021 decided to issue show-cause notices to registration holders/ manufacturers under Section 7 (11)(d) of the Drug Act, 1976 and opportunity of personal hearings. The decision of the Registration Board was endorsed by Authority in its 128th meeting of Authority held on 14th Dec 2021 and decided that “Drug formulations/strengths which were previously registered by the Registration Board but are not available in any Reference Regulatory Authorities, shall be reviewed and disposed-off keeping in view of safety and efficacy evidence/data in the Reference Regulatory Authorities”.

In line with the decision taken by the Board in its 313th meeting, show-cause/personal hearing notices were issued to registration holders for hearing before the Registration Board on 1st February, 2022 at 2:30 pm. However, due to prevailing cases of COVID-19, personal hearings were postponed. Many of registration holders of Famotidine 10mg/5ml and 40mg/5ml Liquid Suspension challenged the Show Cause Notices issued for cancellation of their drugs stating violation of the decision taken in the 70th Meeting of the DRAP Authority held on the 05-09-2019. However, the decision taken in the 70th Meeting of the DRAP Authority has been reviewed in the 128th Meeting held on 14-12-2021, whereby the Registration Board was allowed to review and dispose of the registration of drugs keeping in view their safety and efficacy. The Registration Board in its 315th meeting held on 1st Feb 2022 noted the information and advised to provide the opportunity of a personal hearing in the next meeting of the Registration Board.
