Abstract:
ABSTRACT:The rationale for sustained release oral levodopa preparations is to deliver levodopa in the areas of maximal intestinal absorption in a slow and predictable way, leading to stable plasma levodopa levels and brain dopamine levels, therefore resulting in a lengthened duration of action. Sinemet CR is the prototype of such preparations, with demonstrated efficacy in decreasing periods of akinesia in parkinsonian patients with mild to moderate motor fluctuations. Total doses of levodopa are raised 10 to 30% because of the lowered bioavailability; diphasic dyskinesias may increase at the

Abstract:
Formulations for sustained medication release are very useful in the treatment of chronic disorders. The oral route has selected matrix tablets as the most likely type of prolonged drug release. In order to generate therapeutic activity for a protracted duration, matrix tablets maintain a stable plasma drug concentration and sustain the rate of release of the drug throughout time. In preparations with a short half-life and high dosage frequency, extended-release is crucial. The matrix regulates how quickly the medication is released.

Slow-release devices retained in the rumen, are a simple method for continuous administration of bioactives to ruminant animals. To satisfy regulatory requirements and avoid waste of bioactive due to under- or over-dosing, it is advantageous to have a constant and predictable release rate. Existing intraruminal controlled-release technologies cannot easily be adapted for different bioactives or rates of release and can be influenced by the variable physiological environment in the rumen.

The maceration of dried powder of Garcinia mangostana fruit husk with ethyl acetate gave yellow crystalline powder of mangostin. The yield was calculated as 7.47%. The identification of the Garcinia mangostanahusk extract was carried out by thin-layer chromatography (TLC) and differential scanning calorimetry. The TLC of mangostin was done by using the alumina sheet and ethyl acetate: hexane (3:1) as mobile phase. The Rf value as compared with standard mangostin was

Abstract:
A drug-loaded conductive polymer/hydrogel blend, benzoic acid-loaded poly(3,4-ethylenedioxythiophene/alginate (BA-loaded PEDOT/Alg) hydrogel, was used as a carrier/matrix for an electrical stimuli transdermal drug delivery system (TDDS). The effects of crosslinking ratio, PEDOT particle size, and electric field strength on the release mechanism and the diffusion coefficient (D) of BA were examined by using a modified Franz-diffusion cell. The diffusion scaling exponent value of BA is close to 0.5 which refers to the diffusion controlled mechanism, or the Fickian diffusion as the BA release mec
