Hypertension is the most important risk factor for cardio vascular disease. But, the key question remains: which of the many available types of blood pressure lowering drugs is the better choice as first line medication. Hence, the prospective, randomized, single blind , Comparative study was conducted  at tertiary care Hospital to  assess  the beneficial outcomes of drugs by comparative method. The study concludes that the physicians were prescribed the ACEIs for hypertension with various co morbidities as per JNC-7 guidelines. The study conclude that the A+E+N is the most effective combination therapy for better control of hypertension. The study indicates that the combination therapy can be individualized according to the presence of co morbidities  with  HTN.
