Preliminary pharmacokinetic study of isometamidium chloride in camels

Isometamidium chloride was given to camels at a single intravenous dose rate of 0.5 or 1 mg kg-1 and the plasma drug concentration measured spectrophotometrically at frequent intervals for up to 48 hours. Isometamidium chloride concentrations were found to be 9.8 +/- 0.2 and 8.7 +/- 0.2 micrograms ml-1 half an hour after treatment with 1 and 0.5 mg kg-1, respectively, and 1.7 +/- 0.3 and 0.7 +/- 0.3 micrograms ml-1 after 24 hours. No measurable drug concentration was found 48 hours after dosing.
