[Preparation of ondansetron hydrochloride osmotic pump tablets and their in vitro drug release].

Aim: To prepare ondansetron hydrochloride osmotic pump tablets (OND-OPT) and investigate their in vitro drug release behavior.

Methods: OND-OPT were prepared with a single punch press and pan coating technique. Osmotic active agents and plasticizer of coating film were chosen by drug release tests.

[Preparation of solid lipid nanoparticles by microemulsion technique].

Aim: To prepare solid lipid nanoparticles by microemulsion technique.

Methods: Stearic acid was used as the oil phase, lecithin as surfactant, alcohol as cosurfactant and distilled water as the aqueous phase. Microemulsion was prepared by mixing the above component in proper ratio.
