Many of the procedures used in conventional toxicity testing with animals have arisen by an apparently empirical process (e.g., period of exposure and selection of dose levels). Safety studies are performed with a variety of experimental animals, including rodents, rabbits, nonhuman primates, and farm animals, before progressing to studies with human volunteers, and other animals in the case of veterinary medicines. The individual study designs vary with the chosen animal species, route of administration, duration (dependent on the proposed or estimated exposure in... 

Two patients were hospitalized because of preterm labour and were given i.v. ritodrine. The nadir of neu-trocytes was 199/mm and 13/mm in the two cases, respectively.
