Ketamine is an injectable anesthetic agent with analgesic and antidepressant effects that can prevent maladaptive pain. Ketamine is metabolized by the liver into norketamine, an active metabolite. Prior rodent studies have suggested that norketamine is thought to contribute up to 30% of ketamine's analgesic effect. Ketamine is usually administered as an intravenous (IV) bolus injection or continuous rate infusion (CRI) but can be administered subcutaneously (SC) and intramuscularly (IM). The Omnipod® is a wireless, subcutaneous insulin delivery device that adheres to the skin and delivers insulin as an SC CRI. The Omnipod® was used in dogs for postoperative administration of ketamine as a 1 mg/kg infusion bolus (IB) over 1 hour (h). Pharmacokinetics (PK) showed plasma ketamine concentrations between 42 and 326.1 ng/mL. The median peak plasma concentration was 79.5 (41.9–326.1) ng/mL with a Tmax of 60 (30–75) min. After the same infusion bolus, the corresponding norketamine PK showed plasma drug concentrations between 22.0 and 64.8 ng/mL. The median peak plasma concentration was 43.0 (26.1–71.8) ng/mL with a median Tmax of 75 min. The median peak ketamine plasma concentration exceeded 100 ng/mL in dogs for less than 1 h post infusion. The Omnipod® system successfully delivered subcutaneous ketamine to dogs in the postoperatively. [ABSTRACT FROM AUTHOR] |
