    Notizen: Summary The buccal absorption of procainamide was studied in 4 normal, male volunteers over a pH range of 5–11. In another investigation the same 4 volunteers collected their urine for 24 h after taking 250 mg of procainamide hydrochloride orally on 3 separate occasions, during which urine pH was uncontrolled, acidified by ammonium chloride ingestion or alkalinised by sodium bicarbonate ingestion. The procainamide remaining after buccal absorption and present in the urine samples was determined spectrophotometrically. It was found that neither the buccal absorption nor the renal excretion of procainamide was substantially altered by changes in pH.

    Notizen: Summary Plasma indomethacin levels have been compared in 10 subjects following 100 mg of indomethacin from two different formulations, with similar disintegration and dissolution profiles. In four of these ten subjects plasma indomethacin levels were estimated after pretreatment with, and concurrent administration of, a buffered aspirin. The percentage of protein binding of indomethacin in the presence of salicylate was also estimated. No significant differences between peak plasma indomethacin levels with or without buffered aspirin were detected, but the rate of indomethacin absorption as shown by plasma levels, was significantly increased by pretreatment with and concurrent administration of, buffered aspirin. This was associated with a marked increase in side effects.

    Schlagwort(e): Nifedipine ; antipyrine ; interaction

    Thema: Chemie und Pharmazie , Medizin
    Notizen: Summary The influence of 2 weeks oral intake of nifedipine (2×20 mg) on the oxidative metabolism of antipyrine was investigated in 12 normal volunteers, who had 1050 mg antipyrine solution orally before and after the course of nifedipine. There were no statistically significant differences in the saliva pharmacokinetic parameters of antipyrine on both occasions. However, the metabolite profile of antipyrine in urine showed a significant reduction in the amount of norantipyrine excreted after compared to that before nifedipine administration (16.5 vs 19.6%). This may have implications for drugs that share a similar demethylation pathway with norantipyrine.
