Feto-maternal concentrations of diazepam and W-demethyldiazepam after intra-amniotic diazepam injection.

Ten milligrams of diazepam were injected intraamniotically in 8 mothers prior to therapeutic abortion between 12 and 19 weeks. The diazepam concentrations in the maternal plasma were comparable to those found after the same intramuscular diazepam dose to the mother. The concentration of diazepam in the amniotic fluid 12 to 18 hours after the injection was no longer significantly higher than in the maternal plasma.

Halothane anaesthesia in caesarean section.

The safety and efficacy of halothane anaesthesia were investigated in 97 caesarean sections using 0.4-0.6% halothane added to a mixture of 61 N2O/3-4 1 O2.

Morphine concentrations in plasma after intramuscular administration.

Plasma morphine concentrations were measured by a radioimmunoassay technique following the intramuscular administration of morphine 0.2 mg/kg body weight as a preoperative medication. The highest plasma concentrations were obtained about one hour after the administration of the drug and there was a sevenfold variation in these concentrations between individuals.

Plasma concentrations of diazepam and its metabolites after peroral, intramuscular, and rectal administration. Correlation between plasma concentration and sedatory effect of diazepam.

Plasma levels of diazepam, N-demethyldiazepam and free oxazepam were measured gaschromatographically in ten healthy volunteers after 5 mg of diazepam perorally, intramuscularly and rectally (with three different kinds of suppositories). The best absorption of diazepam was found after peroral administration. After an intramuscular injection a delayed absorption with low plasma concentrations of diazepam was found.

Serum growth hormone, serum immunoreactive insulin and blood glucose response to oral and intravenous diazepam in man.

The effect of diazepam on blood glucose, serum immunoreactive insulin (IRI), and growth hormone (GH) were studied in 10 volunteers who received diazepam in oral doses of 5 and 10 mg, and intravenously 10 mg. They also received placebo and saline treatment. There was a dose-dependent rise in GH after diazepam administration, and the rise was related to the peak plasma level of the drug.

The effect of metoclopramide on the contraction of the human gallbladder.

In a double blind study 45 patients were given either an i.v. injection of 20 mg Primperan (20 mg metoclopramide, Lundbeck, n = 15), 20 mg Metopram (20 mg metoclopramide, Leiras, n = 15) or a corresponding amount of physiological saline (n = 15) and the effect of metoclopramide on the human gallbladder was studied in x-ray examination of gallbladder.
