Formulation and evaluation of a dapsone and fexofenadine HCl immediate release combination tablet
Keywords:
dapsone, fexofenadine HCl, urticaria, immediate release, super disintegrantAbstract
The purpose of the study was to formulate a conventional (immediate release) tablet using a combination of Dapsone and Fexofenadine HCl. Dapsone is a sulfone with anti-inflammatory, immunosuppressive, antibiotic, and antibacterial properties. Fexofenadine HCl is a non-sedating antihistamine approved for the treatment of allergies, whereas Dapsone is used to prevent bacteria from growing and causing red, itching welts. Fexofenadine HCl is an antihistamine that is used to treat allergic symptoms by blocking a natural substance called histamine. Direct compression methods were used to formulate the tablets, which contained super disintegrating polymers such as Ac-di-sol (Croscarmellose sodium). Four tablet formulations were compounded using the direct compression method, with polymer varying ratios. According to the evaluation results, formulations met the specifications when compared to official pharmacopoeias and standards. Different parameters, such as hardness, friability, weight variation, and dissolution studies, were used to evaluate tablets. This formulation of tablet combination of Dapsone and Fexofenadine HCl releases the drug within 60 minutes. Thus, the trial was a success in terms of achieving our goal of developing a tablet with few excipients and a simple manufacturing method.
