Abstract:
Ketamine is an anesthetic agent commonly used for the induction of anesthesia. Ketamine is also given to control pain, for treatment of posttraumatic stress disorder, and to induce bronchodilation in refractory asthma. Moreover, ketamine therapy is gaining ground as an intervention for patients with treatment-resistant depression and individuals who have depression with serious suicidal ideation. Recently, the drug has been used to disrupt maladaptive reward memories in individuals with harmful alcohol consumption behaviors. The stability of 10-mg/mL and 50-mg/mL ketamine solutions stored at ambient and refrigeration temperatures was assessed over 90 days. Methods Three batches of 10-mg/mL and 50-mg/mL ketamine solutions were stored for 90 days under two temperature conditions (2°C-8°C and 22°C-25°C) in amber plastic bottles. Chemical stability was assessed using a stability-indicating high-performance liquid chromatography assay. At each study time, visual inspection and pH assessments of ketamine concentration and pH were conducted. Results For all solutions tested at each condition, the ketamine concentration remaining was at least 98% of the initial concentration over 90 days of storage. Throughout the study period, solution pH remained stable and the color and odor of the suspensions remained unchanged. Conclusion Extemporaneously compounded 10-mg/mL and 50-mg/mL oral solutions of ketamine prepared in a flavored suspending excipient and stored in amber polypropylene plastic bottles were stable for at least 90 days at both ambient and refrigeration temperatures.
