2-Diethylaminoethyl 4-Butylaminobenzoate (farmocaine, T-caine) is an ester-type local anesthetic drug. Like all ester-type local anesthetic drugs farmocaine is very unstable in the body, and in humans they are rapidly hydrolyzed in the plasma. No direct correlation between the saponification and biological activity of farmocaine and similar local anesthetic esters was found. T-Caine has been used as a spray anesthetization of the throat and as a component of Neoarsen black, Neo-percamin S, topical Neozalocain(R) pasta (benzocaine and farmocaine, Neo Dental Chemical Products, Osaka, Japan) and as a calvital powder in dentistry.

Alcuronium (diallylnortoxiferine) is a semi-synthetic substance prepared from C-toxiferine I a bis-quaternary alkaloid obtained from Strychnos toxifera. Alcuronium is a neuromuscular blocking (NMB) agent, alternatively referred to as a skeletal muscle relaxant. Alcuronium is used for endotracheal intubation and to produce muscle relaxation in general anesthesia during surgical procedures. The pharmacological action of alcuronium is readily reversed by neostigmine, and it produced little histamine release. The major disadvantage of alcuronium is that it elicits a vagolytic effect produced by a selective atropine-like blockade of cardiac muscarinic receptors.

Gentiopicrin is a naturally occurring iridoid glycoside. It is a bioactive component of gentian species of medical plants. It has proved to be the strongest inhibitor of myeloperoxidase. It could be absorbed rapidly in mice, but with a low bioavailability, and could distribute to tissues extensively. Gentiopicrin has been reported to be effective against inflammatory conditions such as rheumatoid arthritis, liver illness, fever, digestive and intestinal disorders. Gentiopicrin treatment can exert anti-inflammatory effects on experimental acute colitis through attenuating the expression levels of TNF-α, IL-1β, IL-6, iNOS and COX-2, and it may present the therapeutic potential in the treatment of colitis. The drug inhibits reserpine-induced pain/depression dyad by downregulating GluN2B receptors in the amygdala. Gentiopicrin injection was approved by SFDA for the treatment of acute jaundice and chronic active hepatitis.

Salcolex is a salicylic acid derivative. Analgesic, anti-inflammatory, antipyretic. It is Choline salicylate used in combination with MgSO4.

PHENYLACETYLGLYCINE DIMETHYLAMIDE is a analgesic and antipyretic. Known as Ralgin in Japan. Has being shown to have neurological activity.

Tiaramide is an anti-inflammatory and analgesic drug, which was developed by Fujisawa Pharmaceutical (now Astellas pharma) and used in Japan under the name Solantol for the treatment of different pain and inflammatory disorders. Later on, Astellas recalled the product by reasons other than safety. The mechanism of tiaramide action is unknown.

Nefopam (nefopam hydrochloride) is a potent, rapidly-acting non-narcotic analgesic. It is totally distinct from other centrally-acting analgesics such as morphine, codeine, pentazocine and propoxyphene. Unlike the narcotic agents, nefopam (nefopam hydrochloride) has been shown not to cause respiratory depression. It is indicated for the relief of acute and chronic pain, including post-operative pain, dental pain, musculo-skeletal pain, acute traumatic pain and cancer pain. Its mechanism of action is unclear.

Carbiphene (etomide, SQ 10,269) is a nonnarcotic analgesic agent for the relief of pain. SQ 10,269 is considered to be a non-addicting analgesic agent indicated for the relief of all types of pain, including post-operative pain and pain associated with chronic and recurrent diseases.

Perisoxal citrate is a basic nonsteroidal anti-inflammatory and analgesic drug.

Flufenamic acid is a member of the anthranilic acid derivatives class of NSAID drugs. Like other members of the class, it is a COX inhibitor and prevents the formation of prostaglandins. Flufenamic acid is known to bind to and reduce the activity of prostaglandin F synthase and activate TRPC6.
