Recent Formulation Advances and Therapeutic Usefulness of Orally Disintegrating Tablets (ODTs).

This review highlights the recent formulation advances (different methods of preparation involving various novel approaches) that have been advancing the use of ODT as a popular dosage form. Furthermore, the important characteristics of ODTs that are required for patient compliance and appropriate therapeutic benefit are discussed. In addition to conventional ODTs, ODTs formulated for controlled release of pharmaceuticals and taste masking are also discussed.

Application of hydrogel polymers for development of thyrotropin releasing hormone-loaded adhesive buccal patches.

To utilize hydrogels for fabricating thyrotropin releasing hormone (TRH) adhesive buccal patches, type of hydrogels such as polyacrylic acids (Polycarbophil AA1, Carbopols 934P, 974P and 971P), celluloses (HPMC K4M, K4MCR and K15M), polysaccharide (sodium alginate) and polyacrylic acid combinations with either cellulose or polysaccharide were evaluated for adhesion force, water uptake and swelling capacity. Upon the characterization of hydrogel polymers, TRH-loading of patches fabricated from these hydrogels was evaluated at various polymer concentrations, combinations and ratios and then in vitro release kinetics of TRH from these patches were studied. Results indicated that maximum adhesion force was shown by polyacrylic acids.

In vitro anticancer activities of Leonurus heterophyllus sweet (Chinese motherwort herb).

Objectives: To investigate the anticancer activities of Chinese motherwort herb (Leonurus heterophyllus Sweet; LHS).

Design: Dried LHS was extracted and reconstituted in phosphate-buffered saline. The in vitro antiproliferation activities of the extract were tested against seven human cancer cell lines.
