Poly D,L-lactic acid (PLA) and its copolymers with glycolide PLGA 90:10 and 70:30 were polymerized under various conditions to yield polymers in the molecular weight range 12000-40000 daltons, as determined by gel permeation chromatography. Vancomycin hydrochloride was the hydrophilic drug of choice for the treatment of methicillin resistant Staphyloccoccal(More)
Maternal milk plays an important role in breast milk jaundice (BMJ) development and is the major source of epidermal growth factor (EGF) for neonates. The aim of this study was to investigate whether there is a relationship between EGF levels in the infant serum and in the milk of nursing mothers and BMJ. Two groups were defined: study group (n = 30),(More)
A biodegradable and biocompatible polymeric system was developed for the controlled release of vancomycin for the treatment of brain abscesses. Poly(D,L-lactic acid) (PLA) and its copolymers poly(lactide-co-glycolide) PLGA 90:10 and PLGA 70:30, were prepared. Polymer disks containing vancomycin (VN) were prepared by solvent casting from methylene chloride(More)
Dissolution can best be described as a tool that can provide valuable information about the availability of a drug product. In this study, nine different paracetamol tablet dosage forms available on the Turkish Drug Market have been investigated and physical controls were realized. Paddle and rotating basket apparatus methods were applied to all the(More)
In this study, the effects of surface-active agents in different types and concentrations, added into the coating solution, on release of model hydrophilic compound have been examined. For this purpose, the tablets, prepared with the use of methylene blue as a model substance, were coated by spray coating technique with cellulose acetate solution containing(More)
Pharmaceutical availability or in vitro availability is one of the aspects of drug bioavailability. Dissolution can be described best as a tool that can provide valuable information about the availability of a drug product. Dissolution test was performed on three different designed and formulated of salbutamol tablet formulations marketed in Turkey. The(More)
A congealable disperse phase encapsulation method was used to prepare controlled release lipid microspheres of sulphamethizole as a model drug. Hydrogenated cotton seed oil (HCSO) and stearic acid were employed as the lipid matrix materials. Tween 60 was the droplet stabilizer used to form microspheres. In in vitro dissolution tests, the drug release was(More)
