Abstract
Amylodipine besylate is a anti-hypertensive drug (or) blood pressure reducer, having the 64% bio-availability .in the present study focus on the floating microspheres, they has been used for prolong release and rapid reaction in the stomach at a single dose frequency of administration. The present study was floating microspheres of amylodipine besylate were prepared by using solvent evaporation method with HPMC E-15. The prepared microspheres are evaluated for drug content, entrapment efficiency and in-vitro drug release. from the dissolution study F5 formulation shows more prolong drug release compare to other formulations and it showing buoyancy above 6 hrs from the results concluded that by increasing the polymer concentrations gives slower the drug release and higher the duration of drug release in stomach.
Keywords: floating microspheres, in-vitro drug release, HPMC E-15, solvent evaporation method.
