Praziquantel (PZQ) is an anthelmintic drug used both in humans and animals that can be administered through various routes. There are transdermal formulations for cats, but only oral or subcutaneous dosage forms for dogs. Given the fact that the cat's skin and the dog's skin have different characteristics, which in turn affect bioavailability, we developed a PZQ spot-on formulation for dogs. This study was aimed at determining the plasmatic behavior of topically administered PZQ (Labyes(®)) in adult dogs. Dogs were administered PZQ (14...
