Abstract

Ketoprofen is a potent non-steroidal anti-inflammatory drug compound but is difficult to dissolve in water. This research aims to increase the solubility of ketoprofen through cocrystallization using a urea coformer with the addition of the inorganic salt NaCl. Cocrystallization was carried out using the solvent evaporation method using methanol. The characterization of the cocrystal results included PXRD, DSC, and FTIR. At the same time, the solubility evaluation was carried out using a solubility test in distilled water and a dissolution test in phosphate buffer media pH 7.4. The results showed that ketoprofen forms a cocrystal with the urea coformer, whereas adding NaCl produces a ketoprofen-urea-NaCl cocrystal with a lower crystallinity and melting point. The solubility of ketoprofen-urea-NaCl cocrystals in distilled water was 183.82 ± 2.84 mg/L, while ketoprofen-urea and ketoprofen cocrystals were 174.23 ± 6.83 and 171.12 ± 6.29 mg/L, respectively. The dissolution test in phosphate buffer medium pH 7.4 showed the dissolution rate of ketoprofen-urea-NaCl cocrystals > ketoprofen-urea cocrystals > ketoprofen.

Abstract

Moringa gum is a natural polymer obtained from Moringa oleifera plant and has been used as a stabilizer, binder, disintegrant, and controlled release matrix. Moringa gum has a polyuronide group, which can potentially be a mucoadhesive agent. This study used moringa gum as a mucoadhesive agent in diltiazem HCl mucoadhesive buccal film. This research aimed to determine the effect of the combination of moringa gum and HPMC on surface pH, swelling index, and in-vitro mucoadhesive residence time. Mucoadhesive buccal films were evaluated for weight and thickness uniformity, folding resistance, drug content, surface pH, swelling index, in-vitro mucoadhesive residence time, and characterization in the form of FTIR and release studies. All formulations met the tests of uniformity of weight and thickness, folding resistance, and drug content. The results showed FB as the optimum formula with a surface pH of 5.803±0.101, a swelling index of 7.031±0.134, and a residence time of 505.67±4.51 minutes. FTIR showed no interaction, and the release study showed 82.197±1.178% release at 480 minutes. In conclusion, a combination of moringa gum and HPMC mucoadhesive buccal film has been successfully prepared with moringa gum as a mucoadhesive agent that increases the residence time.
