FORMULATION AND EVALUATION OF FAST DISSOLVING FILM OF FOSINOPRIL

The mouth dissolving film overcomes the shortfalls of conventional quick dispersing/dissolving intraoral tablets. Fosinopril is an angiotensin converting enzyme (ACE) inhibitor used for the treatment of hypertension and some types of chronic heart failure.It undergoes extensive hepatic first pass metabolism, with bioavailability being only 36%. In the present investigation, an attempt was made to formulate fast dissolving film of fosinopril sodium by Solvent casting method using various film forming polymers such as HPMC 5cps, HPMC E-3, HPMC E-15 each being varied at three different concentration(6%,8%,10%). Drug-excipient compatibility studies were carried out by FTIR spectroscopy and DSC. in order to establish compatibility between drug and excipients The results revealed that the drug and excipients were satisfactorily compatible, without any significant changes in the chemical nature of the drug. Prepared films were subjected to different evaluation parameters such as folding endurance, physical appearance, %moisture absorption,drug content uniformity, in vitro disintegration time, in vitro dissolution studies and stability studies. All the formulations show name accurred compliance with pharmacopoeial standards. The stability study shows that no significant changes in films after one month study. Results revealed that the formulations F1 containing 6% HPMC 5cps showed better release property, low disintegration time, good folding endurance and good physical appearance compared to other formulations, so it was selected as the best formulation.
