Development and Characterization of Hydrogel containing Finasteride

Abstract

The major goal of this study was to create a controlled-release dosage form utilizing a cellulose-based hydrogel that was cross-linked with propylene glycol. Hydrogels were made by crosslinking the polymer Sodium Alginate + Na CMC with propylene glycol, a suitable crosslinking agent. There is no indication of interaction between the medication, polymers, and other excipients, according to an IR and DSC analysis. The hydrogel gave good swelling and controlled release properties due to the cross linking process. The effect of Calcium Chloride concentration on drug content and t75 percent CDR was found to be non-significant based on the findings. However, the influence of Calcium Chloride concentration on swelling index was substantial, indicating that as Calcium Chloride concentration rose, the swelling index of the hydrogel decreased. Again, the effect of response time on drug content and t75 of percent CDR was substantial, implying that as reaction time rose, drug content and t75 of percent CDR of hydrogel increased as well. However, the effect of response time on the swelling index was not statistically significant. Drug content, swelling index, and t75 of percent CDR of run BB1 are the best than compared with based on all responses. This run's drug content, swelling index, and t75 percent CDR are respectively 99.5 percent, 276.64 percent, and 3.5 hrs. So BB1 was used to test the improved formulation, which produced the best in vitro release of 94.24 percent in 6hrs. Different kinetic models were fitted to the in vitro data which showed the best model was higuchi with non-fickian mode of drug release and stability data showed that the formulations were stable during the time span of the study. From the study it was concluded that the prepared hydrogel can provide a sustained release effect with better bioavailability which will surely enhance its absorption throughout the body.
