Case studies of enhanced pharmacodynamic activity of poorly oral bioavailable drugs via solid lipid nanoparticles

Abstract

Solid lipid nanoparticles (SLNs) considered as an alternative vehicle for the enhanced oral absorption of drugs, and also to enhance therapeutic effectiveness after oral administration. Pharmacodynamic activity of drug is mainly describes the pharmacological and therapeutic activity of drug to the biological system. Lipid nanoparticles especially SLNs made of physiological inert lipid molecules and helps the lymphatic transport. Numerous literatures is available on the effect of SLNs and other colloidal carrier systems on the pharmacokinetic activity of poorly bioavailable drugs, to improve their oral absorption and also respective mechanisms for the improved oral bioavailability. However, very few literatures is reported on the pharmacodynamic activity and the effect of dose on the pharmacodynamic activity. Therefore, the current review is mainly dealing with the effect of SLNs on the pharmacodynamic activity discussed.   Keywords: Oral absorption, solid lipid nanoparticles, lymphatic transport, pharmacokinetics, pharmacodynamics.
