| benzethonium chloride | A (synthetic) quaternary ammonium salt that is benzyldimethylamine in which the nitrogen is quaternised by a 2-{2-[p-(2,4,4-trimethylpentan-2-yl)phenoxy]ethoxy}ethyl group, with chloride as the counter-ion. An antiseptic and disinfectant, it is active against a broad spectrum of bacteria, fungi, moulds and viruses. | benzethonium chloride |
| bethanechol chloride | The chloride salt of bethanechol. A slowly hydrolysed muscarinic agonist with no nicotinic effects, it is used to increase smooth muscle tone, as in the gastrointestinal tract following abdominal surgery, treatment of gastro-oesophageal reflux disease, and as an alternative to catheterisation in the treatment of non-obstructive urinary retention. | bethanechol chloride |
| cetylpyridinium chloride anhydrous | A pyridinium salt that has N-hexadecylpyridinium as the cation and chloride as the anion. It has antiseptic properties and is used in solutions or lozenges for the treatment of minor infections of the mouth and throat. | cetylpyridinium chloride |
| choline chloride | A quaternary ammonium salt with choline cation and chloride anion. | choline chloride |
| edrophonium chloride | The chloride salt of edrophonium. A reversible inhibitor of cholinesterase with a rapid onset (30-60 seconds after injection) but a short duration of action (5-15 minutes), it is used in myasthenia gravis both diagnostically and to distinguish between under- or over-treatment with other anticholinesterases. It has also been used for the reversal of neuromuscular blockade in anaesthesia, and for the management of poisoning due to tetrodotoxin, a neuromuscular blocking toxin found in puffer fish and other marine animals. | edrophonium chloride |
| suxamethonium chloride | A chloride salt in which the negative charge of the chloride ions is balanced by succinylcholine dications. | succinylcholine chloride (anhydrous) |
