Lisinopril is an antihypertensive agent indicated for the prevention of hypertension, acute myocardial infarction and diabetic nephropathy. It is an angiotensin converting enzyme(ACE) inhibitor. It has a short half-life and undergoes variable first pass metabolism. It is required to be administered two or three times daily which results in poor patient compliance. In this work an attempt was made to formulate & evaluate TDDS for sustained release of lisinopril by solvent evaporation method. Low molecular weight, good permeability and shorter half-life of the drug made it a suitable candidate...
