Metformin Hydrochloride Loaded Mucoadhesive Microspheres and Nanoparticles for Anti-Hyperglycemic and Anticancer Effects Using Factorial Experimental Design.

Background: Metformin hydrochloride (HCl) microspheres and nanoparticles were formulated to enhance bioavailability and minimize side effects through sustained action and optimized drug-release characteristics. Initially, the same formulation design with different ratios of metformin HCl and Eudragit RSPO was used to formulate four batches of microspheres and nanoparticles using solvent evaporation and nanoprecipitation methods, respectively.

Methods: The produced formulations were evaluated based on particle size and shape (particle size distribution (PSD), scanning electron microscope (SEM)), incompatibility (differential scanning calorimetry (DSC), Fourier-transform infrared (FTIR)), drug release pattern, permeation behavior, in vivo hypoglycemic effects, and in vitro anticancer potential.

Surface Deposition and Coalescence and Coacervation Phase Separation Methods: In Vitro Study and Compatibility Analysis of Eudragit RS30D, Eudragit RL30D, and Carbopol-PLA Loaded Metronidazole Microspheres.

Metronidazole (MTZ) has extremely broad spectrum of protozoal and antimicrobial activity and is clinically effective in trichomoniasis, amoebic colitis, and giardiasis. This study was performed to formulate and evaluate the MTZ loaded microspheres by coacervation phase separation and surface deposition and coalescence methods using different polymers like Gelatin, Carbopol 934P, Polylactic Acid (PLA), Eudragit RS30D, and Eudragit RL30D to acquire sustained release of drug. In vitro dissolution studies were carried out in phosphate buffer (pH 7.

Characterization and Compatibility Studies of Different Rate Retardant Polymer Loaded Microspheres by Solvent Evaporation Technique: In Vitro-In Vivo Study of Vildagliptin as a Model Drug.

The present study has been performed to microencapsulate the antidiabetic drug of Vildagliptin to get sustained release of drug. The attempt of this study was to formulate and evaluate the Vildagliptin loaded microspheres by emulsion solvent evaporation technique using different polymers like Eudragit RL100, Eudragit RS100, Ethyl cellulose, and Methocel K100M. In vitro dissolution studies were carried out in 0.

Design, characterization and in-vitro evaluation of different cellulosic acrylic and methacrylic polymers loaded aceclofenac microspheres.

The aspire of this attempt was to design and evaluate aceclofenac loaded sustained release microspheres by emulsion solvent evaporation method, using different polymers like Ethyl cellulose (EC), Kollidon SR (KSR), Eudragit RS 100, Eudragit RL 100 and Hydroxypropylmethyl Cellulose (HPMC K100M). Microspheres were prepared using different stirring rate (1200, 1500, 2000rpm) and larger microspheres were obtained with lower stirring rate. Performance of microspheres was evaluated in terms of in vitro dissolution study which was allowed according to USP paddle method using Phosphate Buffer (pH 6.

In vitro study on tamsulosin release kinetics from biodegradable PLGA in situ implants.

The objective of this study was to evaluate the effect of drug loading and the effect of excipients on the release pattern of tamsulosin tydrochloride from in situ PLGA implants formed in vitro in gelatin gel. This system is prepared by dissolving a biodegradable polymer (DL-PLGA 70K) in biocompatible solvent, dimethyl sulfoxide (DMSO). Then either the drug or drug with excipients was added to it.
