Simple Summary: This study investigated how dexmedetomidine, a sedative, works when given to healthy cats via intramuscular injection at a dose of 10 μg/kg. Nine adult cats were observed before and after receiving the drug, with blood samples taken at various times to measure drug levels. Dexmedetomidine acted quickly, causing sedation that lasted for at least an hour, with peak effects between 20 and 30 min and a half-life of about 70 min. Significant decreases in heart rate, respiratory rate, and blood pressure were observed in the first hour, along with an increase in blood sugar levels after 60 min. Overall, dexmedetomidine proved to be effective and safe for sedation in healthy cats, providing valuable information for veterinarians to ensure its safe and effective use in feline patients. This study investigated the pharmacokinetic profile of and pharmacodynamic response to dexmedetomidine administered intramuscularly (IM) at a dose of 10 μg/kg in healthy cats. Nine adult cats were evaluated before and after administration of the drug, with serial collections of plasma samples. Dexmedetomidine induced deep sedation, with a rapid onset of action and a duration of one hour, reaching a peak between 20 and 30 min after administration. The half-life (T½) was 70.2 ± 48 min, with a maximum concentration (Cmax) of 2.2 ± 1.9 ng/mL and time to reach maximum concentration (Tmax) of 26.4 ± 19.8 min. The area under the curve (AUC) was 167.1 ± 149.1 ng/mL*min, with a volume of distribution (Vd) of 2159.9 ± 3237.8 mL/kg and clearance (Cl) of 25.8 ± 33.0 mL/min/kg. There was a reduction in heart rate (HR) and respiratory rate (RR) in relation to the baseline, with a slight decrease in systolic (SBP), diastolic (DBP), and mean (MAP) blood pressure in the first hour. Blood glucose increased after 60 min. Dexmedetomidine proved to be effective and safe, with rapid absorption, metabolization, and elimination, promoting good sedation with minimal adverse effects after IM administration in healthy cats.
