China Abstract: In-feed Medication has been used for a long time to prevent coccidiosis, a worldwide protozoal disease in rabbits. rabbits and delayed contact hypersensitivity in guinea pigs. Adapalene has been evaluated as safe at much higher dose levels, thus the topical applications of 36mg adapalene/m2/day (% gel) for weeks did not cause any systemic toxicity in rats.

The dose-related scab formation and acanthosis disappeared during 8 weeks of recovery period. Dyphylline is eliminated almost entirely by the kidney. Drug accumulation may occur in patients with impaired renal function. Like other methylxanthines, high plasma levels of the drug may be associated with severe cardio- and neurotoxicity, sometimes without any previous warning.
