Fenoterol is a beta2-adrenoreceptor agonist, used as a bronchodilator for the treatment and prevention of bronchospasms, associated with asthma and chronic obstructive airway disease, including bronchitis and pulmonary emphysema. Fenoterol is also used for tocolysis during premature labor. Marketing of fenoterol for treatment of asthma was suspended in Australia and New Zealand because of an increased risk of deaths, most likely due to excessive self-administration of the drug.

Thiamphenicol is a broad-spectrum antibiotic, which is active against gram-positive and gram-negative organisms. The drug is marketed in Asia and Latin America for the treatment of various infections, including sexually transmitted diseases. As many phenicols, thiamphenicol inhibits the protein synthesis in bacterias by binding to 23S ribosomal subunit. In Europe and USA the drug is used in a veterinary practice.

Fenproporex is a central and indirect-acting sympathomimetic. It was developed as an anorectic drug. Their anorectic effects are believed to be a result of adrenergic activation. Fenproporex has never been approved by the US Food and Drug Administration (FDA) for sale in the US due to lack of efficacy and safety data. There is a paucity of randomized, placebo-controlled trials on Fenproporex. These studies suggest that Fenproporex is modestly effective in promoting weight loss. Data from these studies are insufficient to determine the risk-benefit profile of Fenproporex. Abuse potential and amphetamine-like adverse effects are causes for concern. Adverse effect most frequently reported are: insomnia, anxiety, depression, irritability, dry mouth.

N,N-Dimethylcarbamoylmethyl alpha,2-dimethyl-5H-[1]- benzopyrano[2,3-b]pyridine-7-acetate (Y-23023/ Tilnoprofen arbamel) is a prodrug developed as a new non-steroidal anti-inflammatory drug (NSAID), by Yoshitomi and Japan Tobacco for treatment pain in Rheumatoid arthritis, but was discontinued. Y-23023 is rapidly hydrolysed to an active metabolite, alpha,2-dimethyl-5H-[1]benzopyrano[2,3-b]pyridine-7-acetic acid (TILNOPROFENIC ACID), cyclo-oxygenase inhibitor.

Ciclonium bromide is an antimuscarinic agent that acts by action by directly relaxing the smooth muscles. It is not approved in the USA, but available was marketed in other countries for functional or organic disorders associated with anxiety and emotional tension e.g. gastric and duodenal ulcers, gastritis, hypersecretion and gastric discomfort, spastic constipation, bile duct dyskinesia, renal colic, and dysmenorrhoea.

Butropium Bromide is an anticholinergic and an antispasmodic. It is a Muscarinic receptor antagonist. The drug is used for remission of spasmodic pain in the following diseases: gastritis, enteritis, gastric ulcer, duodenal ulcer, cholelithiasis and cholecystopathy (including cholecystitis, and cholecystic and biliary dyskinesia). It is marketed in Japan under the brand name Coliopan.

Magnesium isoglycyrrhizinate is a magnesium salt form of isoglycyrrhizinate, a derivative of glycyrrhizic acid extracted from the roots of the plant Glycyrrhiza glabra. Magnesium isoglycyrrhizinate has anti-inflammatory, antioxidant and hepatoprotective activities. The drug is believed to be a free radical scavenger and to modulate the activity of hepatic enzymes. Magnesium isoglycyrrhizinate was investigated in clinical trials to restore hepatic impairments caused by chemotherapy drugs and as a treatment of chronic liver diseases.

Dimethylaminopropionylphenothiazine was first synthesized in 1951 by Swedish pharmaceutical company Astra AG. It demonstrated anesthetic and antispasmodic activities in vivo.

Fenethylline (generic name Captagon) is a codrug of amphetamine and theophylline. In the fenetylline molecule, theophylline is covalently linked with amphetamine via an alkyl chain. It was formerly used to treat conditions such as ADHD, narcolepsy, and depression, but its use has been banned because of the potential for abuse. Amphetamine, an agonist for trace amine-associated receptor 1 (TAAR1) with enhancing dopamine signaling (an increase of irritability, aggression, etc.), is the main cause of Captagon addiction. Theophylline, an antagonist that blocks adenosine receptors (e.g. A2aR) in the brain responsible for restlessness and painlessness, may attenuate the behavioral sensitization caused by amphetamine. Fenethylline is included in a list of compounds to be considered by a World Health Organization (WHO) Expert Committee in April 1985 for possible international scheduling under the Convention on Psychotropic Substances, 1971. Fenethylline re-emerged because of its widespread abuse by Middle Eastern young adults. Terrorist groups such as the Islamic State to enhance what they consider desirable characteristics - aggressiveness, alertness, and fearlessness - in their recruits, promote it.

Taurocholic acid is a bile acid and is the product of conjugation of cholic acid with taurine. Its sodium salt is the chief ingredient of the bile of carnivorous animals. Taurocholic acid, as with all bile acids, acts as a detergent to solubilize fats for absorption and is itself absorbed. It is used as a cholagogue and cholerectic (a bile purging agent). Hydrolysis of taurocholic acid yields taurine, a nonessential amino acid. Taurocholic acid is one of the main components of urinary nonsulfated bile acids in biliary atresia. Raised levels of the bile acid taurocholate in the fetal serum in obstetric cholestasis may result in the development of a fetal dysrhythmia and in sudden intra-uterine death. In medical use, it is administered as a cholagogue and choleretic. Taurocholic acid is a potent TGR5 ligand, and in dogs, colonic perfusion with TCA induces PYY secretion. TCA enemas could stimulate GLP-1 and PYY secretion in obese patients with type 2 diabetes receiving the dipeptidyl peptidase-4 (DPP-4) inhibitor, sitagliptin. Satiogen Pharmaceuticals is developing rectally administered taurocholic acid, a bile acid, for the treatment of obesity and type 2 diabetes mellitus.
