Patients and prescribers have recently been affected by interruptions to the supply of all formulations H2 antagonist ranitidine as a result possible contamination with N-nitrosodimethylamine. Here, Marco Motta Mike Wilcock present outcomes their study evaluating implications these shortages for patients taking from six GP practices in Cornwall.
The metabolism of nitrosamines by microsomal cytochrome P-450 (P-450) isozymes was studied in a reconstituted monooxygenase system. P-450 LM2, LM3a, LM3b and LM3c, LM4, and LM6 were purified, respectively, from the livers of phenobarbital-treated, ethanol-treated, untreated, isosafrole-treated, and imidazole-treated rabbits. Of these isozymes, LM3a had the highest N-nitrosodimethylamine demethy...
The pharmacokinetics of N-nitrosodimethylamine was studied in patas monkeys following i.v. doses of 0.5, 1.0, and 5.0 mg/kg and a p.o. dose of 1.0 mg/kg, and in Swiss mice at i.v. doses of 1.0 and 2.0 mg/kg. In the patas monkey the pharmacokinetics was linear over the i.v. dose range studied. The mean clearance (Cl), steady-state volume of distribution (Vss), mean residence time, and eliminatio...
