A COMPARITIVE EVALUATION OF SPECIES OF GUDUCHI (TINOSPORA CORDIFOLIA (WILID.) MEIRS EX HOOK. F & THOMS., TINOSPORA MALABARICA MEIRS EX HOOK, TINOSPORA CRISPA MEIRS.) W.R.T SATWA

Background: Guduchi is a plant belonging to Menispermaceae family and widely used in Ayurvedic system of medicine. Tinospora cordifolia is the accepted botanical source of Guduchi. All the three species are indigenous to the tropical areas of India, Sri Lanka and Myanmar. Guduchi Satwa is the most commonly used dosage form of the plant for various conditions like fever, arthritis, gastric ulcer cough etc. Tinospora cordifolia (Guduchi) is a widely used shrub in folk and Ayurvedic systems of medicine. Species of the plant, stem size, collection time, season and maturity of the plant may affect the yield and physico-chemical profile of Guduchi Satwa. Due to high demand and less yield of Satwa from Guduchi plant, market sample of Guduchi Satwa is subjected to adulteration. Hence this study is aimed at standardizing Guduchi Satwa prepared from all the three available species of the plant. Methodology: The study deals with preparation of Satwa as per the classical text of Ayurveda, identifying organoleptic features, conducting physicochemical and photochemical screening of the Satwa of all the above mentioned species of Guduchi (Tinospora cordifolia (wilid.) Meirs ex hook. f & thoms., Tinospora malabarica meirs ex hook, Tinospora crispa meirs.). Results: The study provided significant difference in the yield of Satwa. Variations in the organoleptic characters were insignificant. All the phytoconstituents were found to be same and the physicochemical values were within the limits in all three species

Analgesic Activity of Sebastiania chamaelea (L.) Muell. Arg.

Background: This study intended to experimentally evaluate the analgesic activity of Sebastiania chamaelea (L.) Muell. Arg. which is widely used by folklore and traditional healers in pain relief. The drug is commonly known as ‘Bhumi Eranda’ among the locals.Methods: The plant material of Sebastiania chamaelea (L.) Muell. Arg. was collected from the fields of Sri Sri College of Ayurvedic Science and Research, Bangalore and preserved as per the standard method. The toxicity studies carried out earlier has proved that, the drug was non-toxic up to 3000 mg/kg body weight. The effective doses were derived as 300 mg/kg (lower) and 600 mg/kg (higher) body weight and the experimental study was conducted. Analgesic screening models used for the study are – Eddy’s Hot plate and Tail immersion models. The study was carried out in 4 groups i.e. Control, Standard, Lower dose Kashaya of Sebastiania chamaelea (L.) Muell. Arg. and Higher dose Kashaya of Sebastiania chamaelea (L.) Muell. Arg. in each model. The activity was compared with a standard reference drug, Tramadol and Diclofenac.Results: The results were analyzed by using one-way analysis of variance (ANOVA) test followed by Dunnett test to detect the significance of differences between each group and control.Conclusion: The study helped to conclude, Sebastiania chamaelea (L.) Muell. Arg. as an ideal analgesic and supported the traditional claim

Exploring the Solubility and Bioavailability of Sodium Salt and Its Free Acid Solid Dispersions of Dolutegravir

Amorphous salt solid dispersion (ASSD) of Dolutegravir amorphous salt (DSSD) was generated using quench cooling and compared to its Dolutegravir free acid solid dispersion (DFSD) to improve the solubility and bioavailability. Soluplus (SLP) was used as a polymeric carrier in both solid dispersions. The prepared DSSD and DFSD, physical mixtures, and individual compounds were characterized by employing DSC, XRPD, and FTIR to assess the formation of the single homogenous amorphous phase and the existence of intermolecular interactions. Partial crystallinity was observed for DSSD, unlike DFSD, which is completely amorphous. No intermolecular interactions were observed between the Dolutegravir sodium (DS)/Dolutegravir free acid (DF) and SLP from the FTIR spectra of DSSD and DFSD. Both DSSD and DFSD improved the solubility of Dolutegravir (DTG) to 5.7 and 4.54 folds compared to the pure forms. Similarly, drug release from DSSD and DFSD was 2 and 1.5 folds higher than that in the pure form, owing to the rapid dissolution of the drug from the formulations. The permeability of DSSD and DFSD was estimated using the dialysis membrane, which enhanced the DTG permeability. The improvement in in vitro studies was translated into in vivo pharmacokinetic profiles of DSSD and DFSD, where 4.0 and 5.6 folds, respectively, improved the Cmax of DTG
