Homatropine (used in a form of bromide or methylbromide salts) is an analogue of atropine, which acts as an antagonist of muscarinic receptors. Homatropine was approved for the treatment of cough in combination with hydrocodone bitartrate.

Potassium Triiodomercurate(II) is a periodometallate salt. It contains a triiodomercurate(1-). It is an antiseptic (topical) and disinfectant. It is also an antiseborrheic agent.

Silver iodide is an inorganic compound with the formula AgI. It is used as a photosensitive agent in photography, as a local antiseptic, as a chemical intermediate, and in cloud seeding for rain-making. The major hazards encountered in the use and handling of silver iodide stem from its toxicologic properties. Effects from exposure may include skin rashes, conjunctivitis, argyria (a permanent ashen-gray discoloration of skin, conjunctiva, and internal organs), headache, fever, hypersensitivity, laryngitis, and bronchitis.

Strychnine is an indole alkaloid obtained from the seeds of the Indian tree Strychnos nux-vomica. It gets its scientific name “strychnos” from Carl Linnaeus, who classified it back in 1753, but it was known to the population of India way before then. Nux vomica originates in India. Strychnine-containing baits are currently labelled for below-ground use and are intended for the control of pocket gophers. Their use as indoor pesticides has been eliminated since 1989. In the past, strychnine has been used as a pesticide to control rats, moles, gophers, and coyotes. Strychnine is highly toxic to most domestic animals. Strychnine is a competitive antagonist at glycine receptors and thus a convulsant. It has been used as an analeptic, in the treatment of nonketotic hyperglycinemia and sleep apnea.

Ethylmorphine is a derivative of morphine with analgesic and antitussive effect. It acts by activating the opioid receptors and thus has a direct influence on the CNS system. Ethylmorphine was approved in Europe for the treatment of dry cough (Codethyline, Dionine).

Potassium Triiodomercurate(II) is a periodometallate salt. It contains a triiodomercurate(1-). It is an antiseptic (topical) and disinfectant. It is also an antiseborrheic agent.

Stibophen (Fuadin), an organic trivalent antimony compound, has been used for many years in the treatment of schistosomiasis. Stibophen is used as treatment of schistosomiasis by intramuscular injection. Stibophen is known to act by selectively inhibiting worm PFK.

BORATE, a salt of boric acid, is used as a food additive in the European Union. This additive is authorized for use as preservatives of sturgeon eggs (caviar).

Valeric acid is a colorless, oily liquid with an unpleasant odor. It is highly corrosive and must be handled with care. Valeric acid is mainly used as a chemical intermediate to manufacture flavors and perfumes, synthetic lubricants, agricultural chemicals, and pharmaceuticals. It is also used as a flavoring aid in foods. Valeric acid is considered safe as a food additive by the World Health Organization.
