Nonlinearities in amoxycillin pharmacokinetics. I. Disposition studies in the rat.

1992

Several features of amoxycillin pharmacokinetics in man are not well known in spite of the extensive clinical use of the antibiotic. In this paper it is demonstrated that amoxycillin disposition kinetics in rats is clearly nonlinear, and that this may be due mainly to its elimination mechanisms. At different intravenous bolus dose levels, and in steady-state perfusion studies, the most striking feature is an increased renal clearance as dose increases (from 3.5 to 7.0 mg kg-1 for intravenous bolus, and from 4.6 to 20.0 micrograms min-1 for intravenous perfusions). This phenomenon has been attributed to a saturation of the active renal tubular reabsorption of the antibiotic. When the intrave…

Renale Wasser- und Elektrolytausscheidung durstender Ratten innerhalb von 32 Stunden nach einmaliger intraven�ser Gabe von Chlormerodrin oder Mersalyl

1959

At the beginning of a period of hunger and thirst, rats received 3 or 4,5 to 5 mg.Hg/kg. as chlormerodrine or mersalyl. The optimal dose of 3mg Hg/kg.as chlormerodrine or 4,5mg. Hg/kg. as mersalyl was effective for more than 32 hours after a single injection.
