Hymecromone (4-methylumbelliferone) is already approved drug in Europe and Asia where it is used to treat biliary spasm. It is used as choleretic and antispasmodic drugs and as a standard for the fluorometric determination of enzyme activity. The concomitant administration of Hymecromone with products, containing metoclopramide, leads to mutual decrease of their action. Due to a danger of diarrhea with subsequent hypokalemia, Hymecromone should be applied with caution to patients on cardiac glycosides therapy (in these cases the sensitivity to them is increased). Hymecromone can be administered simultaneously with otherspasmolytics and analgesics. Very rare allergic reactions, itching, erythema, rashes; diarrhea which normally disappears by reduction of dose or discontinuance of therapy.

Tenonitrozole is an antiprotozoal given in the treatment of trichomoniasis. It is given orally in a dose of 250 mg twice daily with meals, for 4 days.

Phenothiazine, the parent compound of a multitude of present-day drugs, has been employed on an extensive scale for its insecticidal, fungicidal, antibacterial and anthelmintic properties. Phenothiazine was formerly used as an insecticide and as a drug to treat infections with parasitic worms (antihelminthic) in livestock and people. It was introduced as antihelminthic in livestock in 1940 and is considered, with thiabendazole, to be the first modern antihelminthic. Almost a catholicon, its widespread use in animals and man has led to the uncovering of many adverse reactions encompassing effects on blood elements, neuromuscular problems and photosensitization. Its potential side effects have now limited its use. The chemical structure of phenothiazine provides a most valuable molecular template for the development of agents able to interact with a wide variety of biological processes. Synthetic phenothiazines (with aliphatic, methylpiperazine, piperazine-ethanol, piperazine-ethyl, or piperidine side-chain) and/or phenothiazine-derived agents e.g., thioxanthenes, benzepines, imonostilbenes, tricyclic antidepressants, dimetothiazine, and cyproheptadine have been effective in the treatment of a number of medical conditions with widely different etiology. These include various currently clinically used drugs for their significant antihistamic, antipsychotic, anticholinergic (antiparkinson), antipruritic, and/or antiemetic properties.

Tibolone (brand name Livial, Tibofem), also known as 7α-methylnoretynodrel, is a synthetic steroid drug with estrogenic, progestogenic, and weak androgenic actions which was introduced in 1988 and is used widely in Europe, Asia, Australasia, and, with the exception of the United States (where it is not available), the rest of the world. It is used mainly for treatment of endometriosis, as well as for the treatment of symptoms resulting from the natural or surgical menopause in post menopausal women. Women above 60 years of age should only start with LIVIAL treatment when they are intolerant of or contraindicated for other medicinal products approved for the treatment of oestrogen deficiency symptoms. Tibolone is used for the prevention of bone mineral density loss in postmenopausal women at high risk of future osteoporotic fractures who are intolerant of, or contraindicated for, other medicinal products approved for the prevention of bone mineral density loss. Tibolone has similar or greater efficacy compared to older hormone replacement drugs, but shares a similar side effect profile. It has also been investigated as a possible treatment for female sexual dysfunction. Tibolone is a 19-nortestosterone derivative and is related structurally to other 19-nortestosterone progestins. It is the 7α-methyl derivative of noretynodrel. Tibolone possesses a complex pharmacology. Its two major active metabolites, 3α-hydroxytibolone and 3β-hydroxytibolone, act as potent, fully activating agonists of the estrogen receptor (ER), with a high preference for ERα. Tibolone and its metabolite Δ-tibolone act as agonists of the progesterone and androgen receptors, while 3α-hydroxytibolone and 3β-hydroxytibolone, conversely, act as antagonists of these receptors. Lastly, tibolone, 3α-hydroxytibolone, and 3β-hydroxytibolone act as antagonists of the glucocorticoid and mineralocorticoid receptors, with preference for the mineralocorticoid receptor.

Theofibrate (Etofylline clofibrate, trade name Duolip) is the clofibric acid ester of theophylline, used for the treatment of hyperlipoproteinaemia with elevated triglycerides and cholesterol. The low dose of Etophylline clofibrate (750mg) has a similar lipid-lowering effect as pure clofibrate (1500mg), probably due to a synergistic hypolipidemic effect with theophylline, which has no lipid-lowering effect per se. Secondly, etophylline clofibrate substantially decreases platelet aggregability and plasma viscosity, properties which may be desirable in the prevention of coronary heart disease (CHD). Finally, etophylline clofibrate is clearly a less potent inducer of peroxisomal proliferation in the rat liver than clofibrate, bezafibrate or fenofibrate. Theofibrate increases lipoprotein lipase activity to promote the conversion of Very low-density lipoprotein (VLDL) to Low-density lipoprotein (LDL), and hence reduce the level of VLDL.

Salinazid (Acozid, Nupasal-213) is an antibacterial agent used primarily as a tuberculostatic. It used to be the treatment of choice for tuberculosis.

Etofylline [7-(2-hydroxyethyl)theophylline] is a N-7-substituted derivative of theophylline, a smooth muscle relaxant. Etofylline is used to relieve bronchoconstriction. It may act as a phosphodiesterase inhibitor and adenosine receptor antagonist.

Nilvadipine (NIVADIL®) is a L-type calcium channel blocker for treatment of hypertension. It inhibits the influx of extracellular calcium through myocardial and vascular membrane pores by physically plugging the channel. The decrease in intracellular calcium inhibits the contractile processes of smooth muscle cells, causing dilation of the coronary and systemic arteries, increased oxygen delivery to the myocardial tissue, decreased total peripheral resistance, decreased systemic blood pressure, and decreased afterload.

Acivicin is a modified amino acid and structural analog of glutamine, that irreversibly inhibits glutamine-dependent amidotransferases involved in nucleotide and amino acid biosynthesis. Acivicin is a potent antitumor agent that induces apoptosis in human lymphoblastoid cells. Phase I dose-escalating studies conducted in cancer patients administered acivicin showed reversible, dose-limiting CNS toxicity, characterized by lethargy, confusion and decreased mental status.

Gestrinone is a synthetic trienic 19-norsteroid developed for the treatment of endometriosis. Gestrinone exerts its activity by activating androgen and progesterone receptors. The drug was approved for use in Latin America, Australia and Europe.
