Dipipanone are indicated for the management of moderate to severe pain in medical and surgical conditions in which morphine may be indicated. Dipipanone is related to methadone and can be substituted for assorted opioids. The severe or irreversible adverse effects of Dipipanone, which give rise to further complications, include hypotension, hypotension, hependence, agranulocytosis, ischemic colitis, generalized chorea, hypersensitivity hepatitis. It may interact badly with monoamine oxidase inhibitors, which are substances found in some antidepressants and other medication.

Fludiazepam is a potent benzodiazepine and 2ʹ-fluoro derivative of diazepam,[3] originally developed by Hoffman-La Roche in the 1960s. Fludiazepam is marketed in Japan and Taiwan under the brand name Erispan. Fludiazepam exerts its pharmacological properties via enhancement of GABAergic inhibition. Fludiazepam has 4 times more binding affinity for benzodiazepine receptors than diazepam. Fludiazepam possesses anxiolytic, anticonvulsant, sedative, hypnotic and skeletal muscle relaxant properties.

Levomoramide is the levorotatory, biologically inactive isomer of dextromoramide.

Dextromoramide is a synthetic strong-acting opioid and full mu-opioid receptor agonist. Dextromoramide is a Schedule I drug illegal to possess. The current indication for Palfium® (dextromoramide) is severe acute or chronic pain requiring opioids, such as post-operative pain, and pain associated with bone fractures, malignancies and acute renal/biliary colic attacks in adults.

Ketobemidone (Cliradon, Ketogan, Ketodur, Cymidon) is a strong opioid analgesic, structurally related to pethidine, which has been in clinical use for more than 50 years. In the Scandinavian countries ketobemidone is only available in combination with a spasmolytic substance N,N-dimethyl-3,3-diphenyl-I-methylallylamine (A29). Ketobemidone has been shown to be a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist. In spite of a relatively low mu-receptor affinity ketobemidone has a higher analgesic potency than morphine by systemic administration. It is probably due to its higher lipophilicity and consequently more easy penetration into the CNS. Ketobemidone is indicated for the treatment of all types of severe pain, such as postoperative, cancer, kidney stones and fractures.

Cloxazolam is an agonist of GABA-A receptor that was developed in Japan for the treatment of anxiety-disorders. The drug was marketed in Europe under the names Sepazon, Olcadil, Akton and Lubalix.

Oxymestereone is anabolic-androgenic steroid, a methylated derivative of testosterone. The drug was developed in 1960 and was in clinical use under brand names Oranabol, Anamidol, Balnimax, Sanabol, and Theranabol, however, it was discontinued later.

Dexfenfluramine, also marketed under the name Redux, is a serotoninergic anorectic drug. Dexfenfluramine, the dextrorotatory isomer of fenfluramine, is indicated for use in the management of obesity in patients with a body mass index of > or = 30 kg/m2, or > or = 27 kg/m2 in the presence of other risk factors. Unlike fenfluramine, dexfenfluramine is a pure serotonin agonist. Dexfenfluramine increases serotonergic activity by stimulating serotonin (5-hydroxytryptamine; 5-HT) release into brain synapses, inhibiting its reuptake into presynaptic neurons and by directly stimulating postsynaptic serotonin receptors. Dexfenfluramine reduces blood pressure, percent glycosylated hemoglobin, and concentrations of blood glucose and blood lipids, but these benefits may be indirect. Dexfenfluramine may also be of some value in controlling eating habits in diabetic patients, preventing weight gain after smoking cessation, and treating bulimia, seasonal affective disorder, neuroleptic-induced obesity, and premenstrual syndrome. Dexfenfluramine's most frequent adverse effects are insomnia, diarrhea, and headache; it has also been associated with primary pulmonary hypertension. The drug should not be combined with other serotonergic agonists because of the risk of serotonin syndrome. The recommended dosage is 15 mg twice daily. Dexfenfluramine is effective in the treatment of obesity in selected patients. Because its efficacy is lost after six months of continuous treatment, it should be viewed primarily as an adjunct to diet and exercise. Dexfenfluramine was approved by the FDA in 1996 and has been widely used for the treatment of obesity. However, Dexfenfluramine was removed from the U.S. market in 1997 following reports of valvular heart disease and pulmonary hypertension.

Etilamfetamine (Apetinil) is a stimulant drug of amphetamine chemical class. It is an N-substituted amphetamine with an ethyl group on the amphetamine backbone. It was used as an anorectic or appetite suppressant. Etilamfetamine is a psychoactive drug, which can be used as a recreational drug. Etilamfetamine has been abused as a “designer drug” alternative to amphetamine and possibly methamphetamine. It is a dopamine releasing agent.

Zipeprol is disubstituted piperazine that is marketed as a non-opioid antitussive in Europe, Asia, and South America. Zipeprol is not available in the United States or Canada and has been discontinued in Europe. Zipeprol is still available in some countries in Asia and South America. Zipeprol was demonstrated to have anticough effects in animal models, to be active as a blocker of histamine and cholinergic function, to be a potent local anesthetic and to possess bronchiospasmolytic actions. it had no remarkable cardiovascular or gastrointestinal actions in the rat or dog in comparison to codeine.
