Objective: To evaluate the anticonvulsant property of Zingiber officinale as well as its interaction with conventional anticonvulsant drug using Maximal electroshock seizures (MES) model and to evaluate possible mechanism involved in its action. Method: The present study was done after getting ethical clearance. The rhizomes of ginger were authenticated and extraction of dried rhizomes was done by using Soxhlet apparatus to obtain its ethanolic extract. Animals were divided into 4 groups using Phenytoin (25 mg/kg) as the standard drug. The alcoholic extract of Zingiber officinale was given at the doses of 200 mg/kg and 100 mg/kg. The test samples will be given one hour prior to induction of convulsions. Results: In MES model, the alcoholic extract of Zingiber officinale at the doses of 200 mg/kg and 100 mg/kg p.o significantly reduced the duration of tonic hind limb extension (THLE) in mice (P<0.05) in a dose dependent manner as compared to the vehicle control. The extract at a dose of 200 mg/kg body weight is found to be effective nearly...

The antihyperglycaemic activity of aqueous leaf extract of Newbouldia laevis (ALENL) was evaluated in rats. Twenty-five rats of both sexes (120 – 160 g) were divided into five groups (A-E) of 5 animals each. Group A (control) rats were administered 0.5 ml of distilled water (DW) orally while those in group B received 100 mg/kg body weight of ALENL. Animals in groups C, D and E which induced into hyperglycaemia (intraperitoneal administration of 150 mg/kg body weight of alloxan) were also administered DW, 100 and 200 mg/kg body weight of ALENL respectively, once daily for 14 days. Blood glucose levels (BGL) were determined at an interval of two days. Alloxan significantly (p<0.05) increased BGL in the DW treated hyper-glycaemic animals (DWTHA) from 48.00 ± 1.79 to 142.80 ± 2.35 mg/dl after 24 h. After two days, administration of the extract at 100 and 200 mg/kg body weight increased blood glucose level, but this increase was not statistically significant (p>0.05) when compared with the DWTHA. On day 4, the extract...

Objective: There is rapidly growing interest in the development of nanoparticles drug delivery mainly for anticancer drugs as it promises to solve problems to several related to anticancer drugs. The aim of present work was to formulate erlotinib loaded chitosan nanoparticles using probe sonication technique. The objective of the study was to investigate the effect of surface stabilizers and sonication time on the entrapment efficiency of erlotinib loaded chitosan nanoparticles. Methods: In this work, three parameters were evaluated i.e. different surface stabilizers, amount of surface stabilizers (50 – 150 mg) and sonication time (6 – 15 min). The formulated chitosan nanoparticles were characterized by particle size, polydispersity index, percentage yield, loading capacity, entrapment efficiency, differential scanning calorimetry and fourier transform infrared spectroscopy. Results: It was found that batch PNP-11 (formulated using PEG 600 having amount of 50 mg at sonication time ~ 15 min) has a maximum loading capacity 76.07±0.14 (w/w), entrapment efficiency 73.60 ± 0.17% (w/w) and smallest particle size of 59.80 nm out of all the thirteen...

Ledipasvir is an inhibitor of the HCV NS5A protein, which is required for viral replication used in the treatment of hepatitis C. Ledipasvir is practically insoluble (less than 0.1 mg/mL) across the pH range of 3.0-7.5 Due to low solubility, it results into poor bioavailability after oral administration. Therefore, solid dispersions (SDs) of Ledipasvir were prepared by two methods, i.e. spray drying technique and hot-melt extrusion by using various carriers like polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer (soluplus), hypromellose 5 cPs and copovidone (kollidonVA64) to increase its aqueous solubility. Faster and high drug release was found in the SDs which was prepared by spray drying technique (SDT) with co-povidone in the ratio of 1:2 as compared with hot melt extrusion (HME) using drug substance and soluplus in the ratio of 1:2. There are 5 folds increases in the solubility of Ledipasvir prepared by SDT and HME compared with plain drug substance. FSD3 and FHM9 are finalized as optimized formulations prepared by SDT and HME based on their solubility, drug...
