T formulation of pharmaceutical quality dietary supplements that have adequate physical and chemical stability as well as are safe, cost effective and technologically feasible can entail numerous challenges. In contrast to drugs which are usually well defined chemical entities, botanicals are complex ingredients containing multiple chemical components and often several classes of compounds are ...

the present study concerned with the development and characterization of metronidazole microcapsules prepared by thermal change method using different ratios (1:1, 1:2 and 1:4) of ethyl cellulose in order to select the best microcapsule formulation with a good encapsulation efficiency and drug release profile. the obtained microcapsules were discrete, spherical with free flowing properties and ...

background: considering to the high distribution of cockroaches as urban pests, the efficacy of different formula­tions of metarhizium anisopliae strain iran 437c were assessed against the brown-banded cockroach, supella longi­palpa f. under laboratory and field conditions. methods: metarhizium anisopliae isolates were screened with immersing adults of the brown-banded cockroachs in aqueous sus...

the purpose of this study was preparation and evaluation of sustained release matrix type ocular mini-tablets of timolol maleate, as a potential formulation for the treatment of glaucoma. following the initial studies on timolol maleate powder, it was formulated into ocular mini-tablets. the polymers investigated in this study included cellulose derivatives (hec, cmc, ec) and carbopol971p. mann...

double emulsion solvent evaporation technique is one of the most attractive methods used to prepare micro and nanoparticles in pharmaceutical areas of interest, but because of the effects of many formulation factors on the size and release behavior of the fabricated particles, optimization of the formulation factors is needed. in this study various parameters including technical and composition...

Background: The aim of this study was to formulate and evaluate the noble herbal moisturise gel containing Stevia extract. Methods: The cosmetic gel formulation was designed by using aqueous extract of Stevia rebaudiana leaves in varied concentrations (2.5% and 5.0%) and evaluated using physiological measurements in comparision with a control placebo gel. The initial physicochemical parameters ...
