A prospective and hospital based study was conducted on in-patients admitted in a tertiary care teaching hospital. Data regarding patient’s demographic details, diagnosis, complete prescription, and any other information will be collected in a predesigned pro forma. The study reveals that males (58%) were more likely to have reported with hypertension and diabetes. Among all medications the major class of drugs prescribed were calcium channel blockers (44.48%) and diuretics (32.65%). The most common anti-hypertensive drugs prescribed were amlodipine (43.67%), Lasix (27.75%). Out of 339 drug-drug interactions, 53(4.61%) were major, 906 (78.85%) were moderate and 190(16.53%) were minor. Morisky medication adherence scale analysis showed fair adherence to the treatment. The present study concluded that the prescribing pattern of antihypertensive drugs showed less adherence to current JNC-8 guideline.
