The floating microballoons have been utilized to obtain prolonged and uniform release in the stomach. The objective of the present study involves design, development, and characterization of pentoxifylline loaded floating microballoons to prolong their gastric residence time. Pentoxifylline (trisubstituted xanthine derivative) loaded microballoons were prepared by the solvent evaporation techni...

background indomethacin is a nsaid (non-steroidal anti-inflammatory drug) that is used in treatment of pain and inflammatory. immediate and sustained release products of this drug have side effects, so a proper replacement is needed. use of the medicine via topical and cutaneous routs has advantages such as avoiding side effects on gastrointestinal; and supplying an amount of medicine in plasma...

losartan potassium is a well known orally active non-peptide angiotensin ii receptor antagonist. losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin ii by selectively blocking the binding of angiotensin ii to at1 receptors. the drug is reported to promote the decrease in ventricular hypertrophy, salt and water excreti...

The objective of the present study was to develop a practical method to prepare a stable dispersion of TiO2 nanoparticles for biological studies. To address this matter a variety of different approaches for suspension of nanoparticles were conducted. TiO2 (rutile/anatase) dispersions were prepared in distilled water following by treated with different ultrasound energies and various dispersion ...

The objective of the present study was to investigate the applicability of matrix type mucoadhesive oral multiple unit systems (MUS) for sustaining the release of ornidazole in the gastrointestinal tract (GIT). The MUS were prepared by ionotropic gelation method using chitosan and hydroxypropyl methyl cellulose K4M (HPMC K4M) according to 3(2) factorial designs and were evaluated in vitro and i...

phorbiaceae. It is a shrub or small tree reaching 4—5 meters high and native to Thailand, where it is commonly called “Plao phae”. In this paper, we describe the isolation and structure elucidation of newly isolated 3 -(4 -hydroxy-3 ,5 dimethoxyphenyl)-propyl benzoate, 3 -(4 -hydroxyphenyl)propyl benzoate and four known compounds [3 -(4 -hydroxy-3 -methoxyphenyl)-propyl benzoate, poilaneic acid...

The objective of this investigation was to find a simple method for the production of phenolic rich products and sugar derivatives (biopolyols) via separation of liquefied lingocellulosic materials. Liquefaction of lignocellulosic materials was conducted in methanol at 180 °C for 15 min with the conversion of raw materials at about 75%. After liquefaction, the liquefied products were separated ...
