Historically used for minor surgical and diagnostic procedures requiring local anesthesia with concurrent sedation, such as minor dermatological procedures or wound care.
Amylocaine blocks nerve conduction at the application site, producing temporary numbness, while trichloroacetaldehyde acts on the central nervous system to produce sedation and hypnosis.
This is a historical formulation with limited modern use. Chloral hydrate derivatives have largely been replaced by safer alternatives. Use only as prescribed by a healthcare provider, and inform your doctor of any liver or kidney conditions before use.
