Design, Development and Formulation of Antiacne Dermatological Gel

In the present study, Adapalene gels were prepared using CMC Na, HPMC, HPC, Carbomer and combinations of cellulose derivatives; as base and PluronicPE-6200 as penetration enhancer for the treatment of Acne. The gels were evaluated for drug content, viscosity determination, in vitro permeation (Nylone-66) and stability studies. The drug content of the gels was found to range from 98-105.7 %. The viscosity of the gels ranged between 7100-83144 cps. . In-vitro diffusion profile of Adapalene gel (optimized formula F-22) obtained in ethanol with water (80:20) indicate that 40.33% drug release found within 6 hrs. while 35.22% of marketed preparation. Although the difference is insignificant, the percentage release of drug was found to increase in the following order of the polymer composition: Carbopol-980> Carbopol-940> Carbopol-934> HPC > SODIUM CMC> HPC+SODIUM CMC > METHYL CELLULOSE > HPMC > HPC+HPMC. Further the formulation F-22 was found to be stable at accelerated stability condition with respect to percent drug content, release characteristics, pH, transparency, feel and viscosity.

A Validated specific Stability-indicating RP-HPLC method for Aripiprazole and its related substances

Image
ABSTRACT : A validated specific stability indicating reversed-phase liquid chromatographic method was developed for the quantitative determination of Aripiprazole and its related substances in bulk samples, pharmaceutical dosage forms in presence of degradation products. Forced degradation studies were performed on bulk sample of Aripiprazole as per ICH prescribed stress conditions using acid, base, oxidative, thermal stress and photolytic degradation to show the stability indicating power of the method. Significant degradation was observed during basic stress and no degradation was observed in other stress conditions. The chromatographic method was optimized using the samples generated from forced degradation studies and the impurity spiked with Aripiprazole. Good resolution between the peaks corresponds to impuritiy-1, degradation products from the analyte were achieved on YMC PACK C18 column using the mobile phase consists a mixture of Sodium dihydrogen Orthophosphate dehydra...
