Gallamine triethiodide is a neuromuscular blocking agent used as a muscle relaxant during certain medical procedures. It is an organic compound that acts on the neuromuscular junction to block the transmission of nerve impulses to the skeletal muscles. This causes the muscles to relax, allowing for easier manipulation during certain medical procedures. It is typically used in combination with anesthetic agents, such as isoflurane, to provide muscle relaxation during anesthesia. It is also used in conjunction with other muscle relaxants in order to produce deeper muscle relaxation.
Gallamine triethiodide, also known by the brand name Flaxedil, is a non-depolarizing neuromuscular blocking agent (NMBA) that was previously used to relax muscles during surgery. It works by competing with acetylcholine, a neurotransmitter, at the neuromuscular junction, preventing muscles from contracting.

Gallamine triethiodide has been largely superseded by newer NMBA medications with fewer side effects. However, it may still be used in some cases, such as for research purposes.
Here are some of the reasons why gallamine triethiodide is no longer widely used:
- Side effects: Gallamine triethiodide can cause a number of side effects, including tachycardia (increased heart rate), hypertension (high blood pressure), and histamine release (which can cause allergic reactions).
- Not easily reversible: The effects of gallamine triethiodide can be difficult to reverse, which can be a problem if a patient needs to be able to breathe on their own again quickly.
- Newer medications: There are now a number of newer NMBA medications available that are safer and more effective than gallamine triethiodide.
