Every day around the globe Alfaxan injectable anesthetic is used in thousands of anesthesia procedures. Its effectiveness, its wider safety profile and its versatility is raising the bar for injectable agents used in induction and total injectable anesthetic procedures.
Drug use and dependence: Alfaxalone is a class IV controlled substance. Biochemical and research data suggest that alfaxalone has a similar abuse and dependence potential to other class IV drugs such as benzodiazepines and barbiturates.
Alfaxan Intravenous Injectable Anesthetic for Use in Cats and Dogs (hereafter, Alfaxan) contains the neuroactive steroid molecule alfaxalone (3-α-hydroxy-5-α-pregnane-11, 20-dione) and is registered with the Food and Drug Administration for use in dogs and cats for both the induction and maintenance of anesthesia. Although alfaxalone is a steroid molecule, it does not bind to sex hormone, glucocorticoid or mineralocorticoid receptors (i.e. nuclear receptors. 1,2)
Alfaxalone produces anesthetic effects via enhancement of gamma-aminobutyric acid sub-type 1 (GABAA) receptor-mediated neurotransmission. GABAA receptors are widely distributed throughout the mammalian Central Nervous System (CNS). GABA is the major inhibitory amino acid transmitter of the mammalian CNS and receptors are present on almost half of all neurones.3 GABA acts by opening a pore in the receptor allowing the in-flow of chloride ions, causing hyperpolarization. Alfaxalone’s enhancement of GABA’s effects prevents development of action potentials and stops impulse transmission.
The alfaxalone molecule was formulated as an anesthetic agent in the early 1970's, but side effects limited its use. In 2000, Jurox incorporated alfaxalone into a cyclodextrin carrier creating Alfaxan. Users began to enjoy the safety and effectiveness of the drug without the side effects.Find out more
Alfaxan is a clear, aqueous isomolar solution with a pH of 6.05 to 7.0. It is presented in 10 mL single-use vials and does not contain a preservative.Find out more
Alfaxan is metabolized in the liver and eliminated in bile and urine within a few hours after administration. Unpremedicated cats and dogs typically remain anesthetized for 25 and 10 minutes, respectively, from a single dose.Find out more
Cats and dogs have demonstrated acute overdose tolerances of five and 10 times the recommended dose, respectively. Cats tolerate repeat overdoses of five times the recommended dose administered every 48 hours for three doses.Find out more
