Commercially available antibacterial semisolid preparations intended for topical application provide only short-term drug release. A sustained kinetics is possible by exploitation of a biodegradable polymer carrier. The purpose of this work is to formulate a mucoadhesive system with aciclovir (ACV) based on a solid molecular dispersion of this drug in(More)
Hydrophobicity can either be determined experimentally or predicted by means of commercially available programs. In the studies concerning biological activities of pyrazine analogues of chalcones, 3-(2-hydroxyphenyl)-1-(pyrazin-2-yl)prop-2-en-1-ones were more potent than the corresponding 3-(4-hydroxyphenyl)-1-(pyrazin-2-yl)prop-2-en-1-ones. As the(More)
The paper studies retention parameters of the therapeutically most frequently used benzodiazepines, i.e. diazepam, oxazepam, medazepam, chlorodiazepoxide, and nitrazepam. The effect of the pH of the mobile phase, percentual representation of methanol, character of the used buffer and the addition of hexanesulfonic acid on the retention time, shape and(More)
