Stability, compatibility and plasticizer extraction of quinine injection added to infusion solutions and stored in polyvinyl chloride (PVC) containers.

The stability of quinine was determined in various diluents and in polyvinyl chloride (PVC) containers. The release of diethyhexyl phthalate (DEHP) from PVC bags into intravenous infusions of quinine was also measured. We used an injection of two doses of quinine; quiniforme at 500 mg and quinimax at 400 mg in either 250- or 500-ml PVC infusion bags containing 5% dextrose, to give initial nominal concentrations of 2 or 1 mg ml(-1) quiniforme and 1.

Compatibility study of 5-fluorouracil with PVC bags after repackaging into two types of infusion admixtures.

The stability and compatibility of 5-fluorouracil (5-FU) in admixtures for continuous intravenous infusion using PVC bags and administration sets were studied. 5-fluorouracil was reconstituted and diluted to 1.8 mg/ml for infusion in polyvinyl chloride and glass containers, and to 1 mg/ml to 16 mg/ml for storage in polyvinyl chloride bags containing 5 per cent dextrose or 0.

Stability study of fotemustine in PVC infusion bags and sets under various conditions using a stability-indicating high-performance liquid chromatographic assay.

The stability and compatibility of fotemustine, a nitrosourea anticancer agent, in 5% dextrose solution with polyvinyl chloride (PVC) containers and administration sets were studied under different conditions of temperature and light. The drug was diluted to 0.8 and 2 mg ml(-1) in 100 or 250 ml 5% dextrose injection solutions for 1-h simulated infusions using PVC bags and administration sets with protection from light.

Stability, compatibility and plasticizer extraction of miconazole injection added to infusion solutions and stored in PVC containers.

The stability of miconazole in various diluents and polyvinyl chloride (PVC) containers was determined and the release of diethylhexyl phthalate (DEHP) from PVC bags into intravenous infusions of miconazole was measured. An injection formulation (80 ml) containing a 1% solution of miconazole with 11.5% of Cremophor EL was added to 250-ml PVC infusion bags containing 5% glucose injection or 0.

Study of Costus lucanusianus: plant juice, fraction combinations and pharmacologic estimation of natural product total activity.

The juice of Costus lucanusianus fresh stems was split by chromatography using pharmacological measurements on duodenum and uterus to follow activity. The concentration-effect curves of the parent juice and the active fraction alone or associated with other fractions were analysed according to classical methods used for combination drugs. Results show that the active fraction is potentialised by two groups of fractions which are without intrinsic activity.
