Floating microspheres have been showing high potential for gastro retention and provide an efficient means of enhancing bioavailability and controlling the release of drugs. Metformin hydrochloride is an effective antidiabetic that required controlled release due to its Short half-life of about 4.5-7 hours and bioavailability 50-60 %. The present research works aim is to develop, evaluate and statistically optimize the Metformin hydrochloride loaded floating microspheres for treatment of type 2 Diabetes mellitus. Six formulations were prepared by ionotropic gelation method by using various polymers such as HPMC K 100 M, Carbopol 934 P, Sodium bicarbonate etc and natural polymers such as tamarind gum powder and neem gum powder. The prepared microspheres were analyzed for particle size, surface morphology, % yield, % drug entrapment efficiency, in-vitro buoyancy, in-vitro drug release studies, in-vitro drug release kinetics, stability studies etc. From the preliminary trial, F4 Formulation was found to be the best formulation with Particle size of 820± 6.15 µm, in-vitro buoyancy of 95.6% and in vitro drug release of 76.33%. From...

Water solubility is the rate limiting step in dissolution and bioavailability. Olmesartan medoxomil is BCS class-II drugs having low water solubility. Olmesartan medoxomil acts on cardiovascular system and used in the treatment of hypertension as antihypertensive agent. Olmesartan medoxomil have low water solubility and low bioavailability as 26%. In this research study we made Olmesartan medoxomil solid dispersion for increasing water solubility of Olmesartan medoxomil. HPMC and PVP were used as hydrophilic polymer while Lyophilization technique was used as a method of preparation of solid dispersion. We evaluated the effects of freeze drying in process yield, solubility and total Olmesartan content of the solid dispersion. This solubility study shows significant increase in solubility of solid dispersion of Olmesartan medoxomil than pure Olmesartan medoxomil. Dissolution study illustrate that, there was improved dissolution rate when compared to plain Olmesartan. The result and conclusion of this research suggest that the solid dispersion prepared in this research has successfully improved the solubility of Olmesartan...

Aim & Background: Body fluids are sent to clinical microbiology laboratory for culture to find the etiological agent causing the infection. This study was conducted to compare the culture results of sterile body fluids processed simultaneously by both conventional method and BACTEC blood culture system. Methods: Sterile body fluids except blood were included in the study. A total of 61 body fluid samples were received and simultaneously processed by both the culture methods-conventional and BACTEC. Results: In this study, overall culture positivity for BACTEC was 85.25% as compared to 59.02% by conventional system. According to the results of our study, the overall culture positivity was increased by 26.23% by BACTEC method than the conventional method. BACTEC blood culture system detected more pathogenic isolates (52.45%) than the routine conventional culture method (21.31%) and it was found to be statistically significant (p value=<0.005). The most common pathogenic micro-organisms detected by conventional and BACTEC methods in this study were Gram-negative followed by Gram-positive. The mean time to detection of pathogenic isolates by...

Objective: The present investigation aims to develop pH-independent mucoadhesive pellets using the extrusion-spheronization procedure and the inter-polyelectrolyte complex (IPEC) of Chitosan-Carbopol 71G. Miconazole was used as a representative drug in this study. Materials and Method: It was found that the composition of the formulation impacts the extrusion of the prepared dough mass. The generation of pellets within a narrow size range was also studied as a function of spheronization speed and time. The precipitation method was utilized to create IPEC. Compatibility between the drug and the additives was confirmed through FT-IR and DSC testing. Results: The MP3 formulation demonstrated consistent swelling across a wide pH range, without any abrupt alterations in swelling at the pH study points of 4.5 or 7. Evidence from in-vivo X-ray scans indicated that the pellets remained intact in the vaginal canal for an approximate duration of 8 hours. Short-term stability studies of the formulation affirmed its consistency throughout the investigation. Conclusion: The study showed that a Chitosan-Carbopol 71G interpolymer complex can function as a...

The aim of this research was to develop and evaluate a cubosomal gel for the treatment of skin diseases such as athlete’s foot (tineapedis), ringworm (tineacruris) and ringworm (tineacorporis). To increase the penetration of the drug and to provide longer duration of treatment this study was performed. Cubosomes are a novel nanoparticle system loaded with butenafine hydrochloride as an antifungal agent. Cubosomes were designed and approached using a top-down approach. Top-down approach was easy and repeatable also. Cubosomes loaded with Butenafine hydrochloride were prepared by a simple emulsification method using different concentrations of lipid phase GMO and poloxamer 407 enclosed in a cubic gel matrix. The prepared cubosomal dispersion was characterized by Drug Entrapment efficiency and particle size. Optimal formulation of cubosomes were incorporated into carbopol-based hydrogels to form cubosomes hydrogels (cubosomal-gels) characterized by physical morphology, drug release studies, pH, viscosity, and spreadability studies. Among all formulations (F7), was found to have the highest drug release at 24 h of 78.693±0.117%, entrapment efficiency (86.517±0.146) and particle size of...
