Optimization of Self-Double Emulsifying Drug Delivery System Using Design of Experiments for Enhanced Oral Bioavailability of Gentamicin: In-vitro, Ex-vivo and In-vivo Studies.

Water-in-oil-in-water (w/o/w) double emulsions have shown excellent capability in augmenting the enteral bioavailability of BCS class III drugs, besides being effective controlled-release formulations. However, the problem of thermodynamic instability has restrained their industrial applicability. The self-double emulsifying drug delivery system (SDEDDS) is one of several approaches used to improve the stability of double emulsions.

Hepatoprotective activity of Cyperus tegetum rhizome against paracetamol-induced liver damage in rats.

In present study the methanol extract of Cyperus tegetum rhizome (MECT) was evaluated for its effect on paracetamol-induced liver damage in Wistar rats. Serum biochemical parameters viz. serum glutamine oxaloacetate transaminase (SGOT), serum glutamine pyruvate transaminase (SGPT), serum alkaline phosphatase (ALP), total serum protein, total bilirubin content and liver biochemical parameters such as thiobarbituric acid reactive substances (TBARS) and reduced glutathione content were estimated.
