gamma-scintigraphy is applied extensively in the development and evaluation of pharmaceutical delivery systems, particularly for monitoring formulations in the gastrointestinal and respiratory tracts. the radiolabelling is generally achieved by the incorporation of an appropriate radionuclide such as technetium-99m or indium-111 into the formulation or by addition of a non-radioactive isotope s...

the rapidly increasing interest in functional materials with reversibly switchable physico- chemical properties has led to significant work on the development of stimuli responsive membranes. thermotropic liquid crystals with their exceptional properties have potentials for drug-delivery applications. thermoresponsive liquid-crystal-embedded membranes were investigated for the purpose of develo...

BACKGROUND In Huntington's disease (HD), the ratio between normal and mutant Huntingtin (polyQ-hHtt) is crucial in the onset and progression of the disease. As a result, addition of normal Htt was shown to improve polyQ-hHtt-induced defects. Therefore, we recently identified, within human Htt, a 23aa peptide (P42) that prevents aggregation and polyQ-hHtt-induced phenotypes in HD Drosophila mode...

A Prolonged convulsive seizure is the most common neurological medical emergency with poor outcome. An ideal anticonvulsant should be easy-to-use, effective, and safe, and it should also have a long-lasting effect. Benzodiazepines, give via the intravenous or rectal route have generally been used as first-line drugs. In small children, IV access can be difficult and time consuming. Midazolam is...

This review focuses on epithelial drug transport mechanisms in mucosal drug delivery: the final step of a four-part process. Reference is made to the mucosae lining the oral cavity and the gastrointestinal tract, the two mucosae most often succumbing to the side effects of cytotoxic chemotherapeutic drugs. This review will be devoted to carrier-mediated transport, particularly as it relates to ...

The rate of disappearance of ergotamine from the mouth after buccal administration has been studied in seven subjects. Allowance has been made for non-absorptive losses of the drug due to experimental technique. The absorption of ergotamine across the buccal mucosa appears to be a passive process, pH-dependent but independent of ergotamine concentration or the simultaneous presence of caffeine....

Fatal Candida albicans infections in the mucosal system can occur in association with immune-compromised diseases and dysbacteriosis. Currently, amphotericin B (AmB) is considered to be the most effective antibiotic in the treatment of C. albicans infections, but its clinical application is limited by side effects and poor bioavailability. In order to use AmB in the local treatment of oral C. a...

The hydrochloride of Sertraline is a white crystalline powder; slightly soluble in water and freely soluble in ethanol [1]. It is a drug of selective serotonin reuptake inhibitors (SSRI) that is chemically unrelated to other SSRIs, tricyclic, tetracyclic, or other available antidepressant drugs. Sertraline inhibit the inactivation of serotonin (5hydroxytryptamine or 5-HT) by blocking its absorp...

Chewing gums are the type of mobile drug delivery systems. It is useful by means administering drugs either locally or systemically through, oral cavity. The treated chewing gum has through times gained adding acceptance as a medicine system. As compare to that chewable tablets epoxies aren't supposed be swallowed and it can removed from point operation without resort invasive biting gum. MCG s...

Mucoadhesive buccal patches containing propranolol hydrochloride were prepared using the solvent casting method. Chitosan was used as bioadhesive polymer and different ratios of chitosan to PVP K-30 were used. The patches were evaluated for their physical characteristics like mass variation, drug content uniformity, folding endurance, ex vivo mucoadhesion strength, ex vivo mucoadhesion time, su...
