Novel Hydrophilic Oligomer-Crosslinked Gelatin-Based Hydrogels for Biomedical Applications.

Gelatin-based hydrogels have shown good injectability and biocompatibility and have been broadly used for drug delivery and tissue regeneration. However, their low mechanical strengths and fast degradation rates must be modified for long-term implantation applications. With an aim to develop mechanically stable hydrogels, reactive anhydride-based oligomers were developed and used to fabricate gelatin-based crosslinked hydrogels in this study.

Development of Simple Dissolution Methods for Felodipine and Combined Amlodipine Besylate-Indapamide Extended Release Tablets without Stationary (Felodipine) Basket.

Background: The dissolution method for certain drugs needs specialized conditions. Dissolution testing for felodipine extended release (ER) tablets (Plendil® 5 mg) and amlodipine-indapamide fixed dose (Natrilam®, 5/1.5 mg) ER tablets requires the use of a stationary (felodipine) basket in USP Apparatus II.
