Quantitative determination of medazepam, diazepam, and nitrazepam in whole blood by flame-ionization gas-liquid chromatography.
Accurate methods are described for the qualitative and quantitative determination of medazepam, diazepam, and nitrazepam in 5 ml of whole blood. Medazepam and diazepam are analyzed intact and nitrazepam is chromatographed as its trimethylsilyl derivative by flame-ionization gas-chromatography on “1% OV-17.” A supplementary column of “2% OV-1” is used to separate nitrazepam TMS from diazepam whe...
متن کامل1H-NMR investigations on the hydrogen bond formation between the tranquilizers diazepam and nitrazepam and some nucleobases.
The formation of hydrogen bonds between the minor tranquilizers diazepam and nitrazepam and a few nucleobases was studied in deuterochloroform solution by means of proton magnetic resonance spectroscopy. The thermodynamic and spectroscopic data of the associations were evaluated on the basis of a dimer model, using the concentration dependent shifts of the protons involved in hydrogen bonds. Th...
متن کاملEffect of Cyclodextrin Complexation on the Aqueous Solubility of Diazepam and Nitrazepam: Phase-Solubility Analysis, Thermodynamic Properties
The solubility enhancement of diazepam and nitrazepam in water was analyzed depending on temperature and amount of α-cyclodextrin (α-CD), β-cyclodextrin (β-CD) and 2-hydroxypropyl-β-cyclodextrin (2-HP-β-CD). The interactions of drug-cyclodextrin in solution were investigated by the phase-solubility analysis. Diazepam (nitrazepam) content in aqueous complexation medium was analyzed UV spectropho...
متن کاملNitrazepam in premedication.
The sedative effects of nitrazepam in a dose of 5 mg and 10 mg have been compared with Mandrax, a combination of methaqualone 250 mg with diphenhydramine 25 mg. Studies were carried out in gynaecological patients undergoing minor surgical operations using the scoring system previously described. The degree of sedation obtained after administration of the two dose levels of nitrazepam was compar...
متن کاملPolymorphic acetylation of nitrazepam.
Nitrazepam is metabolized in part by nitro-reduction to an amine followed by acetylation. This acetylation step has been shown to be under the control of the same genetic polymorphism as sulphamethazine (syn: sulphadimidine).
