Following i.v. injection of digoxin (1Opg kg-') the ratio between digoxin concentrations in the lumen ofjejunal loops perfused in situ and in plasma (L/P) of guinea pigs increased linearily with time. After 3 h, L/P was 8.7, indicating net secretion of digoxin against a concentration gradient. In qu

β¦ Synopsis
Ionic strength and ionic specificity were found to have a significant influence on the rectal absorption of gentamicin. Sodium was more effective than potassium in promoting rectal absorption, but the enhancing effect of sodium salicylate could not be totally explained on the basis of ionic strength. These data, while helping to elucidate some parameters that affect rectal drug absorption, may offer potential insights into new formulation designs for systemic delivery of water-soluble drugs from the rectal compartment.

The effect of itraconazole (ITZ) on the pharmacokinetics of digoxin (DGX) was investigated in guinea pigs. The plasma concentrations of DGX in guinea pigs following treatment with ITZ (20 mg/kg intraperitoneally (i.p.)) after intravenous (i.v.) administration of DGX (0.125 mg/kg) were significantly
The plasma clearance and metabolicrate characteristics of valproic acid (VPA) were studied using guinea-pigs placed on various (0-08-9pmol ml-'= 11-1303 pg ml-I) steady-state plasma concentrations (CsJ by constant intravenous (i.v.) infusion. The total clearance (CL) was significantly decreased at p
