Dextrotubocurarine Chloride (TUBOCURARINE)

Bristol-Myers Squibb · FDA-approved approved Small molecule Quality 28/100

Dextrotubocurarine Chloride (generic name: TUBOCURARINE) is a tubocurarine Small molecule drug developed by Bristol-Myers Squibb. It is currently FDA-approved (first approved 1945) for Muscle relaxation, function.

Dextrotubocurarine Chloride, also known as TUBOCURARINE, is a non-depolarizing neuromuscular blocking agent developed by Bristol Myers Squibb in 1945. It works by competitively binding to the acetylcholine receptor, preventing acetylcholine from binding and causing muscle relaxation. TUBOCURARINE is used to relax muscles and is off-patent, meaning it is no longer protected by patents. As a result, there are no generic manufacturers of the drug. Key safety considerations include its potential to cause respiratory depression and prolonged paralysis.
