Alfadolone or alphadolone is an oral neurosteroid, which can be useful as an analgesic.

Deptropine citrate is a well-known H1-histamine receptor antagonist and muscarinic receptor antagonist. It is prescribed frequently for treatment of asthma, although there has been a sharp decrease in prescriptions since 1994. Deptropine is gradually being replaced by inhaled beta 2 adrenergic agonists and glucocorticosteroids as the preferred clinical prescription. Recently deptropine has garnered interest as a potential treatment for breast cancer. In vitro studies have shown deptropine citrate has inhibitory effects on cell viability and mammosphere formation in Breast Cancer Stem Cells (BCSCs). However, it does not seem to inhibit the self-renewal capacity of the breast cancer cell line MDA-MB-231 when it is enriched with Cancer Stem Cells.

METHYLMETHIONINE (S-Methionine methyl sulfonium, SMMS) chloride is a derivative of methionine metabolism in some plants. Methylmethionine has therapeutic effects on gastrointestinal ulceration potentially via its ability to promote dermal fibroblast migration and growth. The natural derivative Methylmethionine is biosynthesized from L-methionine which is first converted to S-adenosylmethionine. The subsequent conversion, involving replacement of the adenosyl group by a methyl group is catalyzed by the enzyme methionine S-methyltransferase. Methylmethionine is particularly abundant in plants, being more abundant than methionine. S-Methylmethionine is sometimes referred to as vitamin U, but it is not considered a true vitamin. The term was coined in 1950 by Garnett Cheney for uncharacterized anti-ulcerogenic factors in raw cabbage juice that may help speed healing of peptic ulcers.

Cinnamedrine is an active ingredient of midol (a combination of cinnamedrine hydrochloride, aspirin, phenacetin, and caffeine) used to relieve dysmenorrhea. Midol was an over-the-counter drug, which was discontinued due to a marketing decision.

DIMEFLINE is a pneumokinetic and respiratory stimulant. It has been used for the treatment of respiratory insufficiency. The mechanism of action is unknown.

Amperozide (FG 5606, N-ethyl-4-[4',4'-bis(p-fluorophenyl)butyl]-1-piperazine-carboxamide) is an atypical antipsychotic drug which has relatively weak in vitro affinity for striatal dopamine2 (D2) receptors and a strong affinity for the cortical 5-HT2A receptor. It was shown in animal models, that amperozide could attenuate craving for cocaine. In addition, this drug was studied in patients with schizophrenia and was shown, that several patients had improvements as was assessed by the Clinical Global Improvement Scale. However, these studies were discontinued.

Oxilofrine is a sympathomimetic used to treat hypotensive states, with cardiac stimulatory effects similar to those of ephedrine. It has never been approved for use in the USA as a prescription drug or as a dietary supplement. Oxilofrine has been found (1) to act predominantly as a beta1 agonist increasing the speed and force of heart muscle contraction (inotropic effects), specifically, increasing left ventricular ejection fraction and stroke volume; (2) to increase blood pressure; (3) to have variable effects on heart rate; and (4) to potentially increase oxygen uptake by the lungs.

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.

Amiphenazole, a respiratory stimulant, can be used parenteral and oral. Nicholas Laboratories marketed it under the trade name Daptazole. It was used to treat chronic respiratory failure, by increasing ventilation and by reduction of the pCO2 in some patients. Increased ventilation was brought about by an increase in tidal volume rather than an increase in respiratory rate. In combination with bemegride, amiphenazole was used as an antidote for barbiturate, glutethimide overdose, as well as poisoning from other sedative drugs. Now, this drug is used very rarely, because it replaced by more effective drugs.

Dihydralazine is a compound with antihypertensive properties and is in clinical trials, where is studied its effect on kidney function and hormones in healthy individuals.
