Evaluation about wettability, water absorption or swelling of excipients through various methods and the correlation between these parameters and tablet disintegration.

The invention relates to a method of manufacture of fast-disintegrating tablets, and tablets obtained comprising chemicals, foodstuff, oral drug components and the like. The method is characterized in that the components in pulverized form are contacted with a pressurized liquefied gas or gas mixture, homogenized, introduced into moulds under pressure, and decompressed. The pressurized liquefied gas or gas mixture may further comprise a low-boiling solvent.

Fast-disintegrating tablets

Assessment of oral formulation-dependent characteristics of orodispersible tablets using texture profiles and multivariate data analysis.

Clinical practice suggests orally disintegrating tablets (ODTs) may be subdivided for dose adjustments, however there are no studies evaluating the effect of this practice in ODTs quality parameters. This work was therefore dedicated to elucidating the impact of the tablet subdivision on ten selected ODTs produced by different technologies. Structural properties were assessed using weight; dimensions; image analysis; moisture content and porosimetry evaluations. Functional evaluations were also performed by disintegration and wetting assays. Tablets were evaluated just after subdivision and after an accelerated aging. Outcomes suggest the manufacturing method plays an important role in the suitability of ODTs for subdivision. While tablets containing granules immersed in a powdered matrix structure showed poor subdivision performance, with high weight variation and weight loss, tablets obtained by freeze-drying or direct compression of powder mixtures showed acceptable levels of these parameters and could be subdivided for immediate use. Aged tablets revealed structural and/or functional damages for all analyzed drug products, which includes softening of their matrices, water uptake and darkening, with loss of their disintegration and wetting capacities, which suggest inadequacy of ODTs subdivision for later use. The results exposed in this study could be useful for the clinical decision on the subdivision of this tablets category.

Subdivision of Tablets Containing Modified Delivery Technology: the Case of Orally Disintegrating Tablets

Objective: The objective of present study is to develop orodispersible tablets (ODTs) of zolmitriptan by liquisolid technique using different types of super disintegrants to enhance the disintegration and dissolution of zolmitriptan to improve the bioavailability of the drug. Methods: Liquisolid ODTs of zolmitriptan were prepared from; microcrystalline cellulose (Avicel PH-102) as carrier, colloidal silicon dioxide (Aerosil 200) as a coating material, croscarmellose sodium (CSS), sodium starch glycolate (SSG), and crospovidone (CP) as super disintegrants, and propylene glycol as liquid vehicle. The ratio of carrier to coating material was kept constant in all formulations at 35:1, this ratio was chosen after testing the ratios 10:1, 15:1, 20:1, 25:1,30:1, and 35:1. The ratio 35:1 give optimal results relative to other ratios. The pre-compression evaluation includes: flow properties were measured using the angle of repose and the compressibility index and FT-IR. The prepared liquid-solid system compacts were evaluated for their post-compression evaluation which includes: hardness, friability, wetting time, in vitro disintegration time, drug content and in vitro drug release. Results: The tabletting properties of the liquid-solid ODTs were within the acceptable limits. Among the three super disintegrants, CP found to be the best in term of showing the fastest disintegration time. The optimized selected formula (F11) was prepared using 5% w/w crospovidone, by direct compression showed the shortest disintegration time (24 s), superior drug release profile [ the time required for 80% of the drug to be released (T 80 %) and percent drug dissolved in 2 min (D 2 min) 1.84 min and 87.59%, respectively]. In addition to that, the selected formula had an acceptable hardness and friability, so it was selected as the best formula. Conclusion: The overall results showed that CP was the best super disintegrant of showing the shortest disintegration time while loading factor of 0.125 was the best in the preparing of zolmitriptan liquid-solid ODTs, and this suggested the possibility of utilizing the selected best formula (F11) in the preparation of zolmitriptan ODTs as a new dosage form for oral administration.
