Pharmacokinetics of Intramuscular and Intravenous Glycopyrrolate in Juvenile New Zealand White Rabbits

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Glycopyrrolate is an alternative to atropine to treat bradyarrhythmias in anesthetized rabbits; however, there are no pharmacokinetic studies in the literature. Six female New Zealand White rabbits received glycopyrrolate 0.05 mg/kg intravenously (IV) in the cephalic vein or intramuscularly (IM) in a complete crossover design.

Bilateral simultaneous cataract surgery and intraocular lens implantation in an adult female chimpanzee (Pan troglodytes) inducing monovision

Veterinary Ophthalmology, Volume 28, Issue 2, Page 457-464, March 2025.
Abstract Background Cataract is the major cause of visual impairment in humans. Phacoemulsification with intraocular lens (IOL) implantation is the standard technique for cataract treatment with a high success rate. In a few cases, the surgical cataract procedure and lens implantation have been applied in non‐human primates.
