The aim of this study is to prepare novel sorbitol based extended release tablets by melt dispersion method using carbamazepine as a model drug. Carbamazepine was melted along with sugar alcohol to get melt dispersion granules (MGDs) and was characterized by differential scanning calorimetry (DSC), powder X-ray diffractometry (XRD) and solubility study. The physical and chemical parameters...
Ketorolac tromethamine (KT) containing microemulsion-based gels (MBGs) have been formulated, based on the previous phase diagram studies, using a pharmaceutically acceptable surfactant (soybean lecithin; Epikuron 200) and oil (isopropyl myristate; IPM) and the effect of formulation variables on the release profile of the drug from MBGs through intact guinea pig skin and various artificial membr...
Frequent dosing of the potent anti-androgen, flutamide, is necessary to reach a therapeutic level for the treatment of prostatic carcinoma. Sustained delivery of the drug could reduce the adverse effects such as gastrointestinal disorders and improve patient compliance. In the present study sustained-release matrix tablets of flutamide were prepared by direct compression method using different ...
For many years, dexamethasone has been used as an anti-inflammatory drug and is still one of the safest glucocorticoids for treating various diseases. Due to the wide range of the side effects of this drug, it is essential to find a suitable delivering system for reduction in dosage with increased effectiveness. Electrospinning is one of the fiber fabrication methods which is widely used to dev...
objective eudragits are widely used polymers in the production of oral sustained release dosage forms. the application of these polymers in the production of inert insoluble matrices has been investigated. however the effect of particle size, compaction force and presence of aerosil 200 as a glidant on the properties of eudragit rs and rl matrices prepared by direct compression of their physica...
this study examines the controlled release behavior of both water-soluble (acetaminophen, caffeine, theophylline and salicylic acid) and water insoluble (indomethacin) drugs derived from caesalpinia pulcherrima seed gum isolated from caesalpinia pulcherrima kernel powder. it further investigates the effect of incorporating diluents such as microcrystalline cellulose and lactose on caffeine rele...
Objective(s): In a new approach, following the development in metal oxide chemistry, the ibuprofen as low water soluble nonsteroidal anti-inflammatory drug diffused into synthetic sol-gel derived nano porous g-alumina by an impregnation method in order to increase the solubility and control the drug release in physiological environment. Methods: Sol-gel m...
Objective(s): In this work, electrospun nanofibers were explored as drug delivery vehicles using tetracycline as a model drug. Nanocomposite fibers including chitosan (CS)/poly (ethylene oxide) (PEO) and antibiotic were successfully prepared using electrospinning. CS blended with PEO considering a weight ratio of (90/10), and then, nanofibrous samples were successfully e...
hydrogel based metronidazole bioadhesive tablet (hmbt) was prepared as a novel vaginal delivery system to achieve controlled release of drug from the tablet for vaginal candidiasis. the highly swollen hydrogel were prepared by dissolving chitosan in acetic acid solution containing drug, followed by neutralisation with sodium hydroxide and characterized by sem, dsc and ft-ir and evaluated for % ...
the purpose of the present study was to develop glipizide controlled release nanoparticles using alginate and chitosan thorough ionotropic controlled gelation method. glipizide is a frequently prescribed second generation sulfonylurea which lowers the blood glucose in type-two diabetics. quick absorption of the drug from the gastrointestinal tract along with short half- life of elimination make...
