hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
In this work, the solubilities of pharmaceutical cocrystals in solvent/anti-solvent systems were predicted using PC-SAFT in order to increase the efficiency of cocrystal formation processes. Modeling results and experimental data were compared for the cocrystal system nicotinamide/succinic acid (2:1) in the solvent/anti-solvent mixtures ethanol/water, ethanol/acetonitrile and ethanol/ethyl acet...
Background and purpose: Colchicum kurdicum (Bornm.) Stef. is a monocotyledon plant which is endemic to Iran. The corm and seeds of this plant have some bioactive compounds, especially tropolone alkaloids that are used in treatment of inflammations, rheumatoid arthritis, gout, joint pains, and cancers. This study aimed at optimization of colchicine extraction from the corms of C. kurdicum and ev...
cinnamon is the bark the cinnamomi cassia that exhibits many medical properties such as anti-cancer effect and anti-diabetic effect. moreover, because of its antioxidant activity; it can be used in food industries. many studies have already reported biological and chemical properties of the cinnamon extracted essential oil such as their antimicrobial, antifungal, antimosquito, free radical scav...
The solvent displacement method involves three main steps to obtain nanoparticles: dissolution of both the polymer and the drug into a solvent, mixing of the obtained solution with the anti-solvent, and elimination of the solvent through evaporation. 1 Mixing leads to rapid diffusion of the solvent into the anti-solvent and spontaneous particle formation. Particle formation is extremely rapid a...
In recent years, significant effort has been devoted to the development of drug formulation with the purpose of targeting and controlled release. The micro/nanosizing of drugs has been identified as a potentially effective and broadly applicable approach. In the pharmaceutical industry several conventional techniques have been utilized for particle size reduction. The disadvantages of these tec...
Background and purpose: In medicinal chemistry, molecules containing rhodanine(2-thiazolidine-4-one) ring as a magic multifunctional privileged structural and functional scaffold show a broad range of potent pharmacological properties containing anti-microbial, antiviral, anti-diabetic, and anti-convulsant effects. Evidence suggests that the activity of the rhodanine derivative correlates with ...
