Optimization and in situ intestinal absorption of self-microemulsifying drug delivery system of oridonin.
The objective of this study was to optimize and characterize an oridonin self-microemulsifying drug delivery system (SMEDDS) formulation. A central composite design (CCD) was used to investigate the influence of factors (oil percentage and surfactant to co-surfactant ratio (Sur/Co-s ratio)) on the responses including droplet size, polydispersity, equilibrium solubility and in situ intestine abs...
متن کاملA Self-microemulsifying Drug Delivery System (smedds)
The oral delivery of lipophilic drugs presents a major challenge because of the low aqueous solubility of such compounds. Selfmicroemulsifying drug delivery systems (SMEDDSs) have gained exposure for their ability to increase solubility and bioavailability of poorly soluble drugs. SMEDDS, which are isotropic mixtures of oils, surfactants, solvents and co-solvents/surfactants, can be used for th...
متن کاملSelf-Microemulsifying Drug Delivery Systems: An Attractive Strategy for Enhanced Therapeutic Profile
Ease of administration and painless approach made oral route the most preferred. Poor oral bioavailability is pronounced with the majority of recent active ingredients because of dissolution rate limited absorption. Failure to attain intended therapeutic effect of the poor water soluble drugs by this route led to development of novel drug delivery systems which will fulfill therapeutic needs wi...
متن کاملSelf-microemulsifying drug delivery system for improving the bioavailability of huperzine A by lymphatic uptake
Huperzine A (Hup-A) is a poorly water-soluble drug with low oral bioavailability. A self-microemulsifying drug delivery system (SMEDDS) was used to enhance the oral bioavailability and lymphatic uptake and transport of Hup-A. A single-pass intestinal perfusion (SPIP) technique and a chylomicron flow-blocking approach were used to study its intestinal absorption, mesenteric lymph node distributi...
متن کاملSelf-Microemulsifying Drug Delivery System: Formulation and Study Intestinal Permeability of Ibuprofen in Rats
The study was aimed at developing a self-microemulsifying drug delivery system (SMEDDS) of Ibuprofen for investigating its intestinal transport behavior using the single-pass intestinal perfusion (SPIP) method in rat. Methods. Ibuprofen loaded SMEDDS (ISMEDDS) was developed and was characterized. The permeability behavior of Ibuprofen over three different concentrations (20, 30, and 40 µg/mL) w...
