Fenquizone is the diuretic drug. The distribution of fenquizone labelled with 14C in mice was studied by means of an autoradiographic technique. High concentration of radioactivity was found in the intestine, liver, kidney, blood, myocardium and skeletal muscles in decreasing order at various times after oral administration. The labelled compound did not cross the blood-brain barrier. Fenquizone is a saluretic with a quinazolone structure which acts by blocking reabsorption of sodium in the proximal tubule and the ascending branch of the loop of Henle, as well as in the proximal section of the convoluted distal tubule. At low doses fenquizone has an hypotensive action without showing the characteristics secondary effects of diuretics so that it can be employed for long-term treatments without any risk. Fenquizone showed also a significant decrease of symptoms (headache, dizziness) due to hypertension. No undesirable side effects were observed.

Binedaline is a drug that was investigated as an antidepressant in the 1980s. It`s development for the treatment of major depressive disorder was discontinued. It acts as a selective norepinephrine reuptake inhibitor (Ki = 25 nM), with relatively insignificant influence on the serotonin (Ki = 847 nM) and dopamine (Ki >= 2 µM) transporters.

TOLPROPAMINE is an alkylamine H1-antihistamine used as an antipruritic and topical antihistaminic.

Dipyrone, also known as Metamizole (INN), is an ampyrone sulfonate analgesic, antispasmodic and antipyretic. It was withdrawn from US market in 1977 on the basis of reports of agranulocytosis. Depyrone is still used to treat severe and diffucult for relieving pains of different origin; headache, tooth-ache, pains in the joints, muscles, following traumas and operations, gall and kidney colics, neurites, neuralgias, traumatic cerebrasthenia; inflammation of upper respiratory ways of microbial or virus origin; chorea; febrile states. Mechanism of action of dipyrone is complex. It is believed that dipyrone exerts its action by inhibiting COX-3, and activates opioid and cannabioid systems either itself, or by products of its metabolic degradation.

Rilmazafone (previously known as 450191-S) is a water-soluble benzodiazepine prodrug developed in Japan. It has sedative and hypnotic effects. Rilmazafone induces impairment of motor function and has hypnotic properties. Rilmazafone has no effects on benzodiazepine receptors itself, but once inside the body is metabolised by aminopeptidase enzymes in the small intestine to form the active benzodiazepine 8-chloro-6-(2-chlorophenyl)-N,N-dimethyl-4H-1,2,4-triazolo benzodiazepine-2-carboxamide. Preclinical studies have shown its excellent effects inducing and maintaining sleep with little effect on the skeletal muscle. Earlier the clinical dose for this drug as a premedicant was found to be 2-4mg.
