ABSTRACT

Orally disintegrating drug-delivery system server major benefit over the conventional dosage forms because the drug disintegrates rapidly and dissolve in saliva without the use of water. Lisinopril dihydrate is long-acting angiotensin-converting enzyme (ACE) inhibitor, used in treat hypertension, heart failure and myocardial infarction. the drug to be absorbed slowly and incompletely from GI tract, bioavailability 25% and onset of action is 1 hr. in order to increase the bioavailability and improve onset of action. Lisinopril was formulated as orally disintegrating tablets. Six formulations were prepared using (talc, saccharin sodium, PVP K30, sodium starch glycolate, crospovidone, croscarmellose sodium, aspartame, aerosol, sodium lauryl sulfate, avicel pH101, mannitol, Mg stearate and Roseberry flavor). Among all formulations F1 formulation containing (sodium starch glycolate as
superdisintegrant, sodium lauryl sulfate as wetting agent and avicel as diluent), was found to be better as compared to the other formulations and satisfied the criteria for orally disintegrating tablets which showed drug disintegrated in 15sec and released 100% in 10 mins. We concluded that F1 is the best formula for formulation of Lisinopril orally disintegrating tablets in order to enhance the bioavailability of drug.
