INTRODUCTION: Type 2 Diabetes Mellitus (T2DM) is a chronic disease, with prevalence increasing worldwide and its complications are major causes of early morbidity and mortality. Recent guidelines suggest the individualisation of glycaemic targets and glucose-lowering therapies.
BackgroundHospital settings are of great value in collecting pharmacovigilance data. Introduction of innovative drugs in hospital settings raises safety concerns, but allows the study of these drugs’ safety profile in real life. Hospital Pharmacists may play an important role in these activities.PurposeTo assess the adverse drug reactions (ADRs) profile of 3 recently marketed drugs, introduced in a central hospital.Material and methodsAs part of our active pharmacovigilance programme, a prospective, observational study was carried out on patients receiving fingolimod, telaprevir or boceprevir, between January 2012 and September 2014. ADRs encountered were analysed for age, sex, ADR category and seriousness. Severe, unexpected, frequent, uncommon or rare ADRs were reported to the National Pharmacovigilance System (NPS).ResultsA total of 41 patients were enrolled, median age 44 years, 41% male and 59% female. 253 ADRs were observed In 37 patients. 28 reports regarding 173 ADRs were sent to NPS. As defined by the Naranjo causality assessment of ADRs, 90 were considered to have a possible, 53 a probable, and 1 a definitive causal relation with the studied drugs (NPS response rate: 83%). Most frequently observed ADRs (n = 159) in boceprevir/telaprevir regimens were: anaemia (70%), thrombocytopenia (78%), and pruritus (57%). Regarding fingolimod (n = 94), most frequently observed ADRs were: lymphopenia (60%) and paresthesia (24%); initial dose ECG monitoring was performed in all patients, but symptomatic bradycardia was seen in only two cases, without stopping treatment.Severe ADRs occurred in 5%, and moderate ADRs in 16% of the patients. Some patients had to stop taking the drug in all drugs studied.ConclusionADRs were common in patients taking the triple drug regimen for hepatitis C, while fingolimod was relatively well tolerated, which is in line with international literature data. Frequency and severity of ADRs can be managed by laboratory and clinical vigilance and instituting appropriate measures.References and/or AcknowledgementsNo conflict of interest.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
