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. |
| Background | Health 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 Pakistan | Accordingly, 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. |
