Abstract
The main objective of the present research work was to formulate and evaluate transdermal gel loaded with microspheres of Baricitinib to increase bioavailability and to reduce the dosing frequency and to improve patient compliance. Gel loaded with microspheres of Baricitinib was prepared by taking different ratios and grades of Carbopol polymers. The prepared formulations (F1–F9) were evaluated for pre-formulation studies, percentage yield, particle size, content Uniformity, drug content entrapment efficiency and in vitro dissolution studies. The optimized gel loaded with microspheres of F8 formulation (drug: Carbopol 974polymer in 1:1 ratio) is more effective compared to all formulations. The prepared gel showed acceptable physical properties such as particle size of (126.5 microns), percentage yield of (96.5%), content uniformity (97.8), and drug content entrapment efficiency (90.5%). In vitro dissolution studies have shown 100.1% drug release in 12 h. With the optimized formulation Baricitinib emulgels are formulated using different grades and ratios of Carbopol and optimized microsphere formulation F8. The Emulgel formulation F7 showed the acceptable results with a yield of 92.3%, Drug content (100.2%), Spread ability (13.38 g.cm/s), Viscocity (112.3 cP), pH off 6.05 and it was observed that formulation F7 showed 100.2% drug release within 12 hours. All the results show that the gel loaded with microspheres of Baricitinib can be effectively used for the treatment of viral infections like small fox.
