Preparation and optimization of microemulsion of rosuvastatin calcium.
Due to very less bioavailability (20%) of Rosuvastatin calcium, an attempt was made to develop and optimize microemulsion formulation. Capmul MCM, Tween 20 and PEG 400 were selected as oil, surfactant and cosurfactant respectively as the drug is having higher solubility in them. 3:1% w/w S:CoS was selected as it gave higher microemulsion area. Optimized batch (ME-1) was selected having 5% Capmul MCM, 50% Tween 20:PEG 400 and 45% water based on evaluation parameters globule size, zeta potential, PDI, % transmittance.
