Extent of Pharmacotherapy in Covid-19: An Observational Study in a Dedicated Hospital in Bangladesh

Abstract

Objective: With the rapid increase in the rate of infection, repurposing use of many drugs like antivirals, antibiotics, LMWH, steroid, oxygen therapy were considered as an option to find promising anti-COVID therapeutics. In this study, we aim to observe the extent and variety of drugs used in different clinical categories of COVID-19 patients admitted to hospital in Bangladesh. To observe the requirement of oxygen therapy according to severity was also a prime objective to reveal the overall trend, frequency, and pattern of pharmacotherapy in a COVID-dedicated hospital.
 Materials and method: A total of 1348 patients were admitted, of whom 473 were included in this single-center retrospective study. The critical group consists of 99 ICU patients, the severe group has 38, moderate was 82 and mild group 254 cases, admitted in the general ward. Hospital records of each patient were screened and information about drug and supportive therapy were collected manually by the researchers in the data collection sheet. Data express in MS excel spreadsheet and result expressed in percentage.
 Results: Critical group received remdesivir (85.86%), favipiravir (27.28%), meropenem (92.93%), moxifloxacin (87.88%) dexamethasone (41.48%), Low Molecular Weight Heparin (98.99%). They also received supportive O2 therapy like High Flow Nasal Cannula (67.68%), Non-Invasive Ventilation (26.67%), and mechanical ventilator (6.06%). A severe group of patients receives the same group of drugs 97.27%, 5.26%, 60.53%, 47.37%, methylprednisolone (55.26%), and 100% LMWH. A moderate group of the patient received favipiravir (97.56%), cephalosporin (64.67%), LMWH (89.02%) and low flow O2 (97.36%) in a higher percentage. All patients of the mild group received doxycycline, ivermectin. Total 33 patients transfuse convalescent plasma.
 Conclusion: Antiviral, broad-spectrum antibiotics, anti-protozoal, LMWH, corticosteroid, and oxygen therapy are the available treatment option against different clinical categories of admitted COVID-19 patients.
