(also known as Butyn ) is a para-aminobenzoic acid (PABA) ester local anesthetic. Historically used as a fast-acting alternative to cocaine, it has largely been superseded by modern amides like lidocaine in clinical practice. Core Identity & Medical Use
The drug was removed from the U.S. market in 1990 but remains available as a Research-Only Compound for laboratory studies. Pharmacological Mechanism butacaine sulfate
Typically found as a white or off-white crystalline solid. Molecular Formula: (often cited with a molecular weight of approximately in its sulfate salt form). (also known as Butyn ) is a para-aminobenzoic
It features a more rapid onset and a more prolonged duration of action compared to cocaine. market in 1990 but remains available as a
Like other local anesthetics, it works by inhibiting voltage-gated sodium ion channels in nerve cells. This prevents the propagation of electrical impulses, effectively blocking the transmission of pain signals.
Experimentally, it has been studied as an inhibitor of phospholipase A2 , an enzyme involved in inflammatory processes.
It can modulate the activity of phospholipids (like cardiolipin) and stimulate the rate of cation translocation in certain experimental models. Chemical & Physical Properties Chemical Class: Ester of -aminobenzoic acid.
