Aim: The aim was to evaluate the extent and factors responsible for underreporting (UR) of adverse drug reactions (ADRs) in India., Materials and Methods: A retrospective observational, cross-sectional prospective questionnaire-based analysis was undertaken to evaluate the extent and factors for UR of ADRs in pharmacovigilance., Results: At the time, this report was prepared, 90 ADR Monitoring Centers (AMC) were operational in India. Indian AMC functional rate was 56.45%. The average number of Individual Case Safety Reports reported by our center via VigiFlow per month was 48.038. In a period of the 3 years the total number of ADRs reported was 3024. The average number of reports per month was 80.08. Active surveillance versus spontaneous reporting contributed 66.13% versus 33.86% of the total ADRs (P < 0.0001). Outpatient Department (OPD) contribution was 76.05% and indoor contribution was 23.94% of total reports (P < 0.0001). Department of Medicine (33%), followed by oncology (19.27%) and chest disease (13.49%) contributed maximally. The contribution of Pharmacology ADR monitoring OPD was 16.20%. Eye, ear, nose and throat and surgery, private Medical Colleges, hospitals in periphery, sub-district and district contributed no ADRs. ADR detection rates by clinical presentation, biochemical investigation and diagnostic tools were 84.33%, 14.57%, and 1.09% respectively (P < 0.0001). Reporting by postgraduate, registrars, consultants and nurses were 72.65%, 6.58%, 16.56% and 4.19% respectively (P < 0.0001). PG students in Pharmacology contributed an average number of 5.61 ADR reports/month. The lack of knowledge and awareness about Pharmacovigilance Programme of India (PvPI), lethargy, indifference, insecurity, complacency, workload, lack of training were the common factors responsible for UR. Major academic activity, exams, thesis and synopsis submission time influenced reporting of ADRs by postgraduate students., Conclusion: UR is a matter of concern PvPI. Multiple interventions are needed to improve ADR reporting.

Non-steroidal anti-inflammatory drugs (NSAIDs) are known to cause gastrointestinal (GI) bleed. Co-administration of proton pump inhibitors (PPIs) has been widely suggested as one of the strategies to prevent these GI complications among NSAIDs users. Herein, we present a case of severe GI bleeding in a patient taking fixed dose combination (FDC) of rabeprazole (20 mg) and diclofenac sodium (100 SR).

Cilnidipine is a 4(th) generation dihydropyridine calcium channel blocker approved recently for the treatment of essential hypertension. It is not known to present with ankle edema like amlodipine. Moreover, it has been proposed as an alternative anti-hypertensive for patients with amlodipine-induced edema. We report a case of cilnidipine induced ankle edema.
