Background: Dilated cardiomyopathy (DCM) is an important underlying cause of congestive heart failure and/or arrhythmias. The introduction of therapy combining diuretics, digoxin and angiotensin converting enzyme inhibitors (ACEI) has significantly decreased mortality and morbidity. The aim of the study was undertaken to identify the pattern of drugs most commonly prescribed for DCM and to assess the rationality behind such use.Methods: This was a prospective study undertaken between 1st July and 31st August 2015. Prescriptions were reviewed and analyzed using the World Health Organization (WHO) indicators for drug utilization studies. Rationality and cost of therapy per prescription was also evaluated.Results: We encountered 78 patients of DCM in the OPD of Cardiology (prevalence of 4.94%). The average number of drugs per prescription was 6.64. Generic prescriptions were made in 90% encounters. As part of therapy, diuretics and ACE inhibitors or angiotensin receptor blockers, were prescribed in all cases. Our results show a distinctive drug use pattern where beta blockers were used more commonly than digoxin. Other commonly prescribed agents were antiplatelet drugs and statins. Antibiotics were prescribed in 8.7% cases and no injectable drug was prescribed. Average drug cost per encounter was 10.63 INR.Conclusions: To conclude, we found a typical and rational pattern of drug use. Diuretics, ACEI and beta blockers were found to be most commonly used agents. This study provides a clear picture of drug use in this special clinical condition in rural Bengal and paves the way for larger and long term studies.
Objectives:The main objective is to compare efficacy and safety of pregabalin and amitriptyline monotherapy with their low-dose combination in patients of neuropathic pain (NeuP).Methodology:In this parallel-group, open-label interventional study at the Neurology Outpatient Department of Bankura Sammilani Medical College, a total of 147 patients were randomly allocated into three groups and were prescribed the following drugs – Group P (n = 42) pregabalin 150 mg once daily, Group A (n = 34), amitriptyline 25 mg once daily, and Group Z (n = 37) = pregabalin (75 mg) + amitriptyline (10 mg) as combination once daily. They were followed up after 4, 8, and 12 weeks. Efficacy was assessed by NeuP symptom inventory score (NPSI) and safety was assessed by treatment-emergent adverse events.Results:Final assessment was done on 92 patients (P = 31, A = 31, Z = 30). Males were predominant (71.7%). NPSI score significantly decreased in every group from baseline (P < 0.0001). There was no difference of NPSI score between groups at any level of follow-up. Percentage of adverse drug reactions were maximum (44.9%) in amitriptyline monotherapy group and lowest in combined group. However, amitriptyline monotherapy was the cheapest treatment option among these three.Conclusion:Combining pregabalin and amitriptyline at low doses proved to be equally effective but more tolerable compared to individual higher dosage monotherapy. However, if tolerability is good, amitriptyline monotherapy can be an attractive choice in economically challenged group of patients.
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.
