Trolamine, an organic compound, is the salt formed between triethanolamine and salicylic acid. It is widely used as a topical analgesic. 10% trolamine salicylate medical products sold over-the-counter such as are creams for temporarily relief of minor aches and pains of muscles and joints associated with arthritis, simple backache, lumbago, neuralgia, strains, bruises, and sprains. The FDA approved in 1958 otic solution drops containing triethanolamine polypeptide used in the ear to break down and loosen earwax was discontinued. Trolamine can enhance skin healing by recruiting macrophages and modifying the concentrations of various immunomodulators. Trolamine (Biafine; Genmedix Ltd, France) is commonly prescribed at the beginning of radiotherapy for preventing acute radiation-induced skin toxicity in China. Biafine has been studied in radiodermatitis and Phase 2 clinical trial has been initiated in 2016 by Sun Yat-sen University to establish the efficacy of trolamine (Biafine) for the management of radiation dermatitis in patients with nasopharyngeal carcinoma receiving IMRT.

IOTHIOURACIL, in a form of sodium salt, was used as an antithyroid agent in the treatment of hyperthyroidism. It is selectively incorporated into the melanin pigment of melanomas during biosynthesis by serving as false melanin precursors. Radiolabelled (125I) IOTHIOURACIL may be used as a radiopharmaceutical for diagnosis and therapy of melanotic melanomas.

Hexamethonium is a nicotinic cholinergic antagonist. It was used to treat hypertension, but has never been approved and was discontinued because of the non-specified treatment. When this drug tried to use in medical study via inhalation, one of the volunteer died, the death has been described as “particularly disturbing ”because it was a healthy volunteer who had no thing to gain by taking part in the study. This volunteer participated in a study designed to provoke a mild asthma attack in order to help doctors discover the reflex that protects the lungs of healthy people against asthma attacks. Hexamethonium is poorly absorbed from the gastrointestinal tract and does not cross the blood-brain barrier. Now it is widely used a research tool.

Metabutethamine hydrochloride was used as a local anesthetic.

Decamethylene disquaternary salts, with a ten-carbon (C10) chain between the quaternary groups, had the most potent curariform action in the series of polymethylene bisquaternaries. Decamethonium was used clinically as a neuromuscular blocking drug for a short time. Decamethonium was different from d-tubocurarine and that it produced a transient augmentation of contraction. C10 produces neuromuscular block by initiating some active response in the endplate or muscle fibre. Unlike d-tubocurare, decamethonium was not reversed by anticholinesterase agents.

MERCAPTOMERIN is a mercurial diuretic used for the treatment of congestive heart failure. It is an effective diuretic not only when given intramuscularly and intravenously but also when given subcutaneously.

Antazoline is an antagonist of histamine H1 receptors. It selectively bind to but does not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine. Antazoline in combination with naphazoline (VASOCON-A®) is indicated to relieve the symptoms of allergic conjunctivitis.

Alverine is a smooth muscle relaxant used for the treatment irritable bowel syndrome. Alverine may increase calcium influx during action potentials due to inhibition of the inactivation of L-type calcium channels, but may also suppress evoked activity by inhibiting the sensitivity of contractile proteins to calcium.
