Neuromuscular blocking drugs are often classified into two broad classes: Pachycurares, which are bulky molecules with nondepolarizing activity; Leptocurares, which are thin and flexible molecules that tend to have depolarizing activity. [5] It is also common to classify them based on their chemical structure.
Depolarizing neuromuscular blockers: Depolarizing agents act as agonists for acetylcholine receptors. Succinylcholine is currently the only depolarizing neuromuscular blocking drug that has been placed in ongoing clinical use. Its pharmacological structure resembles two acetylcholine molecules combined through acetate methyl groups. [11]

A muscle relaxant is a drug that affects skeletal muscle function and decreases the muscle tone. It may be used to alleviate symptoms such as muscle spasms, pain, and hyperreflexia. The term "muscle relaxant" is used to refer to two major therapeutic groups: neuromuscular blockers and spasmolytics.
Anticholinergic drugs are used to treat a variety of conditions: Dizziness (including vertigo and motion sickness-related symptoms) Extrapyramidal symptoms, a potential side-effect of antipsychotic medications; Gastrointestinal disorders (e.g., peptic ulcers, diarrhea, pyloro spasm, diverticulitis, ulcerative colitis, nausea, and vomiting)
Pancuronium, the first aminosteroid neuromuscular blocking agent to be introduced. Aminosteroids are a group of steroids with a similar structure based on an amino - substituted steroid nucleus. [ 1 ] [ 2 ] They are neuromuscular blocking agents , acting as competitive antagonists of the nicotinic acetylcholine receptor (nAChR), and block the ...
Ibuprofen (Advil or Motrin), naproxen (Aleve) and aspirin (Bayer or Ecotrin) are common pain relievers that belong to a class of medication called non-steroidal anti-inflammatory drugs (NSAIDs).
Decamethonium, which has a short action time, is similar to acetylcholine and acts as a partial agonist of the nicotinic acetylcholine receptor.In the motor endplate, it causes depolarization, preventing further effects to the normal release of acetylcholine from the presynaptic terminal, and therefore preventing the neural stimulus from affecting the muscle.
