Colforsin daropate (a derivative of Colforsin) is cardiotonic, adenylate cyclase activator. It is reported as an ingredient of Adehl in Japan. Colforsin daropate hydrochloride is used for the treatment of acute heart failure. Colforsin daropate is capable of directly stimulating adenylate cyclase, which in turn causes vasorelaxation via elevated intracellular concentrations of cyclic adenosine monophosphate, making it a useful therapeutic tool in treating cerebral vasospasm.

Methylephedrine is one of the ephedra alkaloids that is found in varying amounts in different species of the plant genus Ephedra. Methylephedrine is a popular antitussive, bronchodilator, analgesic, antipyretic, and widely used mixed with other drugs in preparations for treatment of the common cold. N-Methylephedrine, its salts, optical isomers, and salts of optical isomers are in FDA list of Exempt chemical mixtures.

Rupatadine is characterised as a non-sedating H1 anti-histamine and platelet-activating factor (PAF) receptor antagonist. Rupatadine is indicated for the treatment of allergic rhinitis and urticaria. Rupatadine is a safe and well tolerated drug in patients over 2 years old, with no central nervous system or cardiovascular effects and it can be taken with or without foods.

Imipraminoxide (brand names Imiprex, Elepsin) is a tricyclic antidepressant and imipramine metabolite that was used in Europe for the treatment of depression. In comparison with the imipramine, Imipraminoxide efficacy was identical to imipramine. However, in clinical trials, imipraminoxide was found to have a faster onset of action, and fewer and less marked side effects, including diminished orthostatic hypotension and anticholinergic effects like dry mouth, sweating, dizziness, and fatigue. Imipraminoxide's pharmacology has not been well elucidated, but based on its very close relationship with imipramine, it likely acts as a serotonin and norepinephrine reuptake inhibitor and serotonin, adrenaline, histamine, and muscarinic acetylcholine receptor antagonist, though with weaker antiadrenergic and anticholinergic actions
Levormeloxifene (INN) is an experimental selective estrogen receptor modulator (SERM) that was being developed as an alternative to estrogen replacement therapy for the treatment and prevention of postmenopausal bone loss. Levormeloxifene is the levorotatory enantiomer of non-hormonal, non-steroidal oral contraceptive -- ormeloxifene (trade names Novex-DS, Centron, and Sevista). The development of Levormeloxifene was stopped because of a high incidence of gynecologic adverse events during clinical trials.

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.

Vetrabutine is a spasmolytic agent. As a musculotropic spasmolytic agent vatrabutine was reported to act directly on the smooth muscle fibers and to have no neurotropic activity. In pigs, its activity was specific to the uterine body and cervical musculature where it acted on the myometrial cells, sealing off the membrane against the passage of potassium ions, thereby increasing membrane potential and lowering tonus. Vetrabutine was of moderate acute oral toxicity. Vetributine hydrochloride has been used in human medicine as a spasmolytic agent in obstetrics.

Bisdequalinium (also known as R-199, trade name Solvidont) is an antibacterial agent for endodontic use. Bisdequalinium was available in three dispensing forms: an irrigation solution, a working solution, and a medication paste. They contained 0.125 %, 0.5 %, and 0.48 % Bisdequalinium respectively. The low cytotoxicity and high antimicrobial effects, detergent, and lubricating and chelating properties, all claimed in the manufacturer's brochure, make this material an appropriate candidate for clinical endodontic use.

Etilefrine is a cardiac stimulant used as an antihypotensive. Intravenous infusion of this compound increases cardiac output, stroke volume, venous return and blood pressure in man and experimental animals, suggesting stimulation of both α and β adrenergic receptors. However, in vitro studies indicate that etilefrine has a much higher affinity for β1 (cardiac) than for β2 adrenoreceptors. Intravenous etilefrine increases the pulse rate, cardiac output, stroke volume, central venous pressure and mean arterial pressure of healthy individuals. Marked falls in pulse rate, cardiac output, stroke volume and peripheral bloodflow, accompanied by rises in mean arterial pressure, occur when etilefrine is infused after administration of intravenous propranolol 2,5 mg. These findings indicate that etilefrine has both β1 and α1 adrenergic effects in man. The French Health Products Agency concluded that etilefrine and heptaminol have an unfavourable harm-benefit balance, and also placed restrictions on the use of midodrine.
Acefylline is a stimulant drug of the xanthine chemical class. It acts as an adenosine receptor antagonist. Acephylline piperazine is a theophylline derivative with a direct bronchodilator action. It has the advantages over theophylline in being far less toxic and producing minimal gastric irritation. It is indicated for the treatment of asthma, emphysema, acute and chronic bronchitis associated with bronchospasm.Acefylline relaxes smooth muscles, relieves bronchospasm & has a stimulant effect on respiration. It stimulates the myocardium & central nervous system, decreases peripheral resistance & venous pressure & causes diuresis. The mechanism of action is still not clear, inhibition of phosphodiesterase with a resulting increase in intracellular cyclic AMP does occur, but not apparently at concentrations normally used for clinical effect. Other proposed mechanisms of action include adenosine receptor antagonism, prostaglandin antagonism & effects on intracellular calcium. Sodium phenobarbital is a non-selective central nervous system depressant that is primarily used as sedative-hypnotic.
