title: Constant rate of infusion--improvement of tests for teratogenicity and embryotoxicity.
abstract: Sodium salicylate was used as a model substance to investigate whether the embryotoxic effects on rat fetuses varies between two modes of administration. A marked increase in fetal adverse effects was observed at analgetic doses with the once-a-day bolus regimen compared to the constant rate input. The difference was less marked at antirheumatic levels.
