title: Pharmacokinetic predictions based on a variable dosage frequency in chronic treatment.
abstract: After repeated intramuscular or oral administration, plasma drug levels are predicted by using a programmable calculator. Predictions are based on a one-compartment, open model with first-order absorption. The actual times of dosing are considered, so that the assumption of a constant dosing interval is not required. A brief analysis of the pharmacokinetic consequences that may result from a variable dosage frequency is presented.
