Abstract

Objective: Orally Disintegrating Tablets (ODTs) have revolutionized pharmaceutical drug delivery, offering a patient-friendly alternative for those struggling with conventional tablet swallowing. This study delves into the impact of superdisintegrants (crospovidone, sodium starch glycolate, and croscarmellose sodium) on the in vitro characterization of Ketoprofen-containing ODTs. ODTs are designed to rapidly disintegrate in the oral cavity without water, enhancing patient compliance, ensuring faster therapeutic onset, and providing convenience. Material and Method: The micromeritic properties of pre-compression Ketoprofen ODT blends were assessed for bulk density, tapped density, Hausner ratio, and compressibility index. ODTs were formulated using a direct compression method to maintain component uniformity. Comprehensive characterization included weight variation, tablet hardness, friability, wetting time, and in vitro disintegration time assessments. The drug content was determined through UV spectrophotometry of dissolved ODTs, and dissolution studies were conducted in pH 6.8 phosphate buffer using USP apparatus XXIV. Result and Discussion: Results showed uniform tablet mass and favorable powder mixture flowability, ensuring ODT physical properties. Tablets exhibited excellent mechanical resistance with consistent hardness and low friability loss. All formulations demonstrated high and uniform drug content. Different superdisintegrants influenced wetting, disintegration, and dissolution times. Crospovidone exhibited the fastest wetting time but longer disintegration times, attributed to increased tablet hardness. Dissolution studies revealed that crospovidone-containing ODTs had faster drug release compared to croscarmellose sodium and sodium starch glycolate, aligning with literature findings. The study emphasized the importance of considering both wetting and disintegration times for a comprehensive evaluation of ODT performance. Croscarmellose sodium and sodium starch glycolate hindered drug release, forming gel-like masses impeding dissolution, while crospovidone enhanced drug release in formulated ODTs. In conclusion, the study provides valuable insights for pharmaceutical development and patient-centric drug delivery solutions, showcasing the influence of superdisintegrants on ODT performance and emphasizing the importance of considering various parameters for comprehensive evaluation.
