DESIGN AND IN VITRO EVALUATION OF ACRIVASTINE AS ORODISPERSIBLE TABLET USING DIRECT COMPRESSION METHOD

The aim: This study aimed to develop mouth-dissolving tablets of Acrivastine, an antihistamine medication, in order to increase its oral bioavailability.

Materials and methods: Different super disintegrants, such as crospovidone, croscarmellose sodium, and sodium starch glycolate, were used to make Acrivastine oral dispersible tablets (ODTs). These super disintegrants were utilized in various concentrations. The formulation (F3) with 6% w/w crospovidone had a fast disintegration time (less than 30 seconds) and practically total drug release within 10 minutes. All of the formulations were made using the direct compression method and proper diluents, binders, and lubricants. Fourier transform infrared spectroscopy (FTIR) tests were used to investigate the drug-ex¬cipient interaction, and all formulations demonstrated improved drug-excipient compatibility.

Results: The average weight of all formulations was between 175 and 180 mg. All formulations' hardness and friability were within acceptable ranges. Direct compression tablets had a hardness of 3.2 to 4 kg/cm2. All formulations were determined to have a friability of less than 1.0%. For oral dissolving tablets, the in vitro disintegration time is critical, and this time preferred to be < 60 seconds. The results also showed that crospovidone disintegrated after 24 seconds and sodium starch glycolate disintegrated in 40 seconds in vitro.

Conclusions: When compared to croscarmellose sodium and sodium starch glycolate, crospovidone performs better as a super disintegrant. In comparison to other formula, tablets breakdown in the mouth in 30 seconds and have a maximum in vitro drug release time in 1-3 minutes.
