Hydrochlorothiazide (HCT) is a class IV drug which has limited solubility and permeability, for overcome this problems co-crystallization method is used. Co-crystallization is the process to enhance the physical properties of drug molecule especially the solubility. HCT belongs to diuretic category and Atenolol (ATL) belongs to Beta blocker category they are combined for use in tablet formulation. Co-crystallization was used to combine two drugs in single solid phase and thus to achieve new approach for combination therapy to treat hypertension. Using the new approach co-crystals of ATL with HCT was prepared. Co-crystallization of two drugs were carried out by using solvent evaporation and solution co-crystallization method. The saturation solubility was done to evaluate the solubility of co-crystals. Comparative drug release study was carried out between co-crystals and marketed formulation. The prepared co-crystals have shown several times faster release than marketed tablet and co-crystals were characterized by using DSC, FTIR and...

Chenopodium ambrosioides Linn, member of the National List of Medicinal Plants of Interest to SUS (RENISUS), is used to treat different diseases and shows good potential to generate products of interest to the Brazilian Unified Health System “Sistema Único de Saúde” (SUS). However, the use of herbal derivatives implies the control of their quality and the evaluation of their toxicity. Pharmacopeial tests were performed aiming at the physicochemical and microbiological characterization of leaves and extract of C. ambrosioides. The toxicity of the extract was assessed using MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide) and acute toxicity was assayed in mice. The results showed that the leaves and the extract presented acceptable pharmacopeial parameters and the preliminary phytochemical analysis showed the presence mainly of saponins, terpenes, phenols and tannins in the hydroethanolic extract of C. ambrosioides. The microbiological evaluation of the extract indicated no apparent growth of pathogenic microorganisms. Although the extract showed cytotoxicity at high concentration, no signs of acute oral toxicity could be observed at the tested doses. These results, besides the...

A new potential allelochemical (A) m.f. C34H42O19, m.p 168-170 ◦C, [M]+ 754 (FABMS) along with two known compounds Scutellarin 7-O-β-D-glucopyranoside (B), Luteolin (C) were isolated from methanolic extract of the stems of Cassia Siamea Lam. The structure of a new allelochemical (A) was characterized as 3,7-dihydroxy-5,3′,4′-trimethoxyflavone-3-O-β-D-xylopyranosyl-7-O-α-L-rhamnopyranosyl(1→4)-O-α-L-arabinopyranoside, on the basis of extensive spectroscopic analysis, colour reactions and various chemical degradations. Compound A exhibited higher radical scavenging activity in the (DPPH) (1,1-diphenyl-2-picrylhydrazyl) assay...

Anti-stress activity of hydro-alcoholic extract of Sauropus androgynous leaves was investigated against experimentally induced stress in rats using forced swimming endurance test and chronic cold restraint stress test. Acute toxicity study was performed and hydro-alcoholic extract of Sauropus androgynous leaves was found to be safe at a dose of 2000 mg/kg bodyweight. Two doses 200 mg/kg (SALE-200) and 400 mg/kg (SALE-400) of the extract was subjected to the evaluation of anti-stress activity. The parameters like cholesterol, triglycerides and corticosterone were estimated to determine the anti-stress activity. The animals pre-treated with SALE-200 and SALE-400 significantly restored the altered biochemical and physical parameters, when compared with stress control group. In addition the histopathology of the adrenal gland also confirmed the anti-stress activity of the extract as the SALE-400 treated groups showed significant recovery and SALE-200 treated groups showed moderately significant recovery of architecture of the adrenal gland. However, the maximum activity was observed at 400 mg/kg bodyweight. The findings of the present study concluded that the hydro alcoholic extract of Sauropus...

Kawasaki Syndrome (KS) can be a widespread vasculitis affecting many systems, and some of the other recognized complications are discussed, including those affecting the skin, nervous system, gastrointestinal tract, musculo-skeletal system, kidneys, lungs, eyes and haematological effects. There is no specific diagnostic test or pathognomonic clinical features; those previously mentioned clinical criteria have been established to assist physicians in diagnosing Kawasaki disease (KD). We are reporting a case of 1 year 3 months child who has successfully relieved by the IgG and Aspirin therapy. A greater awareness on the part of paediatricians is now contributing to increased recognition of this entity even in India. We suggest that physicians should be cognizant of the fact that they must individualize every patient’s management to the best of their knowledge and judgment, rather than merely going by the...
