Enhanced oral bioavailability of valsartan using a polymer-based supersaturable self-microemulsifying drug delivery system

: A novel, supersaturable self-microemulsifying drug delivery system (S-SMEDDS) was successfully formulated to enhance the dissolution and oral absorption of valsartan (VST), a poorly water-soluble drug, while reducing the total quantity for administration. Poloxamer 407 is a selectable, supersaturating agent for VST-containing SMEDDS composed of 10% Capmul ® MCM, 45% Tween ® 20, and 45% Transcutol ® P. The amounts of SMEDDS and Poloxamer 407...
