title: [Pharmacokinetics of antipyrine, nifedipine and diazepam in experimental myocardial infarct].
abstract: It has been shown, that antipyrine, nifedipine, diazepam pharmacokinetics changes in different ways after myocardial infarction. On day 7, 14, and 21 after myocardial ischemia antipyrine T1/2 increased considerably, and antipyrine Cl and Kel decreased. Nifedipine T1/2 increased on day 7 only. There were no diazepam pharmacokinetic changes during restoration period. However, microsomal diazepam metabolism changed significantly. Diazepam hydroxylation increased on day 7 of myocardial infarction, and on day 14 and 21 did not differ from the control. Diazepam metabolites content changed considerably during restoration period. Under myocardial infarction cytochrome P-450 isoenzymes, oxidizing present substances seem to be altered to different extent.
