Fig. 3From: Slow-release praziquantel for dogs: presentation of a new formulation for echinococcosis controlResults of one HPLC-HRMS run of one dog plasma sample taken after the administration of 100Â mg/kg of the new slow-realease formulation. Smoothed curves (SM) resulting after a total running time (RT) of 20.00Â min; RTÂ =Â retention time at peak of the signal; AAÂ =Â area under the curve; mebendazole was used as internal stanard (IS). Identification of the compounds as R-PZQ, S-PZQ and mebendazole (the internal standard) was made possible by calculations based on the mass-to-charge ratio (m/z) valuesBack to article page
