Prescribing Pattern in Coronary Artery Disease: A Prospective Study
Prescribing pattern of various drugs prescribed in coronary artery disease was studied. It is a prospective, observational study in the Department of Cardiology at Global Hospital, Hyderabad conducted from January 2012 to September 2012. Pattern of different drugs prescribed in coronary artery disease were analyzed. 170 patients were included in the study. Out of these, 124 (72.94%) were male patients and 46 (27.06%) were female patients. Most of the patients diagnosed with coronary artery disease were of the age group of 46-66 (72.36%). The most common co-morbid conditions were hypertension in 110 (64.71%) and diabetes in 66 (38.82%) patients. The prescription pattern of various cardiovascular drugs were found to be as – antiplatelet drugs 169 (99.41%), antihyperlipidemic drugs 162 (95.29%), antibiotics 158 (92.94%), anti-anginal drugs 137 (80.59%), antihypertensives 110 (64.71%), anticoagulants 110 (64.71%), diuretics 106 (62.35%) and bronchodilators 31 (18.24%). Non-cardiological drugs use was also recorded. The average number of drugs per prescription was found to be 9.68 and the percentage of drugs prescribed by generic name was found as 1.76%. The percentage of encounters with an antibiotic prescribed was 92.94%. The most commonly prescribed drug classes in coronary artery disease were antiplatelet drugs followed by antihyperlipidemics and antibiotics. This was followed by anti-anginal drugs, antihypertensives and anticoagulants. Polypharmacy (9.68 drugs per prescription) was noticed. Very few drugs were prescribed by generic name. The prescribing pattern could be improved by reducing the number of drugs per prescription and by prescribing generic drugs to reduce the economic burden of the patients.
