Slow release of insulin from a biodegradable matrix implanted in diabetic rats.
This report describes the development of a long-acting insulin accomplished by the slow release of hormone from an implantable, biodegradable matrix. Rats made diabetic with streptozotocin received a single subcutaneous implant of insulin-albumin microbeads that released biologically active insulin for periods up to 3 wk. The mean fasting blood glucose level for treated animals was 88 mg/dl as ...
متن کاملSubconjunctivally Implanted Hydrogels for Sustained Insulin Release to Reduce Retinal Cell Apoptosis in Diabetic Rats.
PURPOSE Diabetic retinopathy (DR) is a leading cause of blindness in diabetic patients that involves early-onset retinal cell loss. Here, we report our recent work using subconjunctivally implantable hydrogels for sustained insulin release to the retina to prevent retinal degeneration. METHODS The hydrogels are synthesized by UV photopolymerization of N-isopropylacrylamide and a dextran macro...
متن کاملDevelopment and In vitro Evaluation of Sustained Release Matrix Tablets of Theophylline using Hydrophilic Polymer as Release Retardant
In the present investigation, an attempt has been made to increase therapeutic efficacy, reduce frequency of administration and improve patient compliance by developing sustained release matrix tablets of theophylline. Sustained release matrix tablets of theophylline were developed by using drug and different concentrations of polymer such as 10, 20, 30, 40 and 50%. Hydroxypropylmethylcellulose...
متن کاملHydrophilic Natural Polymers for Sustained-controlled Release of Calcium Hydroxide
Calcium Hydroxide (CH) is commonly employed as intracanal medicament in endodontics. In order to maximize its therapeutic effects, it is essential to develop new approaches for preparing the controlled drug release systems which, in turn, facilities the dissociation of CH into calcium and hydroxyl ions. This work studies the sustained-controlled release of calcium ions and the effect of pH chan...
