The half-life of this drug is about 1.9 - 3 hours that indicatingit a candidate for the extended release formulation. Our investigation relates to development of extendeddrug delivery system based on Hydroxy propyl methyl cellulose (HPMCK4...

treatment, biologically. Levobunolol HCl occuserts were prepared using hydroxypropyl methylcellulose (HPMC, 3% & 4%), poly vinyl pyrrolidone (PVP, 1%), methyl cellulose (MC, 1% & 2%) as polymers by solvent casting technique with objectives of increasing contact time, achieving controlled release, reduction in frequency of administration and greater therapeutic efficacy. Based on their physioche...

The current study deals with the synthesis of novel hydroxypropyl methyl cellulose acrylate (HPMCAA) by the process of esterification of hydroxypropyl methyl cellulose and acryloyl chloride. The polymers were characterized by FTIR spectrophotometry, DSC, XRD and haemocompatibility studies. The microstructures of the HPMC and HPMCAA powders were studied under a scanning electron microscope. The ...

background: with respect to the prevalence of leishmaniosis in our country and the problems occurred in the therapeutic approaches and also with respect to the previous successful reports of paromomycin efficacy in this regard, the present study was conducted to determine the effects of paromomycin and gentamicine sulphate on promastigotes of leishmania major.materials and methods: it was an ex...

lisinopril dihydrate (angiotensin converting enzyme inhibitor) is a lysine derivative of enalaprilat and does not require hydrolysis to exert pharmacological activity. it has an extensive hepatic first pass metabolism resulting in a bioavailabil-ity of 6-60%. to overcome the poor bioavailability of the drug, transdermal patches have been prepared. the present study also aims at optimization of ...
