Carpronium chloride is a hair growth reagent with a vasodilatory action. In vivo studies indicated that carpronium chloride achieved dilatation of vascular smooth muscle in the microcirculation of rats. FUROZIN SOLUTION 5% (active ingredient Carpronium chloride) has local vasodilating effect and hair growth stimulatory effect to improve alopecia and vitiligo. It is usually used for the prevention of hair loss, for hair growth stimulation, and in the treatment of seborrhea sicca and vitiligo vulgaris.

Mabuterol is a long acting βeta 2-adrenergic agonist which stimulates adenylyl cyclase activity and the closing of calcium channels. Studies indicate that the R enantiomer of mabuterol is more potent than the S enantiomer. In addition, the half-life is longer in the R enantiomer than the S. Studies conducted on rats and dogs show that mabuterol acts as a bronchodilator. At high concentrations mabuterol can also antagonize beta1 adrenoceptors in guinea pigs

Sarpogrelate (brand name Anplag; former developmental code names MCI-9042, LS-187,118) is a drug which acts as an antagonist at the 5HT2A and 5-HT2B receptors. It blocks serotonin-induced platelet aggregation and has applications in the treatment of many diseases including diabetes mellitus, Buerger's disease, Raynaud's disease, coronary artery disease, angina pectoris, and atherosclerosis.

Zacopride is a potent antagonist at the 5-HT3 receptor and an agonist at the 5-HT4 receptor with antiemetic, anxiolytic and nootropic effects in animal models. Zacopride also has pro-respiratory effects, both reducing sleep apnea and reversing opioid-induced respiratory depression in animal studies. Zacopride has been tested in clinical trials for the treatment of schizophrenia but was found unsuccessful.

NS-3 (montirelin, CG 3703) is an analog of thyrotrophin releasing hormone (TRH). More potent and longer acting than TRH, CG-3703 produced beneficial effects in animal models of concussion-induced unconsciousness, cerebral ischemia, memory disruption, spontaneous convulsions in rats, narcolepsy, and spinal trauma. Given its efficacy in these models, the potential indications were broadened to include seizures, nerve trauma, cognitive dysfunction, and sleep apnea.

Dihydromorphine is a semi-synthetic opioid derived from morphine. dihydromorphine is a moderately strong analgesic and is used clinically in the treatment of pain and is also the active metabolite of dihydrocodeine. Dihydromorphine acts as an agonist at the μ-opioid (mu), δ-opioid (delta) and κ-opioid (kappa) receptors. Dihydromorphone is approved for clinical use in the United States, Europe, and Japan; and sold under the brand name Dilaudid. Similar to morphine, and other morphine derivatives, hydromorphone has a high potential for addiction and abuse and is listed as a Schedule II drug in the United States Controlled Substances Act of 1970 (and similarly regulated in other countries).

Moxonidine is a second-generation, centrally acting antihypertensive drug with a distinctive mode of action. Moxonidine activates I1-imidazoline receptors (I1-receptors). Imidazoline I1-receptor agonism represents a new mode of antihypertensive action to inhibit peripheral alpha-adrenergic tone by a central mechanism. Adrenaline, noradrenaline and renin levels are reduced, a finding consistent with central inhibition of sympathetic tone. Moxonidine acts centrally to reduce peripheral sympathetic activity, thus decreasing peripheral vascular resistance. In patients with mild to moderate hypertension, moxonidine reduces blood pressure (BP) as effectively as most first-line antihypertensives when used as monotherapy and is also an effective adjunctive therapy in combination with other antihypertensive agents. It improves the metabolic profile in patients with hypertension and diabetes mellitus or impaired glucose tolerance, is well tolerated, has a low potential for drug interactions and may be administered once daily in most patients. Moxonidine is a good option in the treatment of patients with mild to moderate hypertension, particularly as adjunctive therapy in patients with the metabolic syndrome.

Roxindole (EMD-49,980) is a dopaminergic and serotonergic drug which was originally developed for the treatment of schizophrenia. Roxindole has also been investigated as a therapy for the major depressive disorder, Parkinson's disease, and prolactinoma. Roxindole is dopamine autoreceptor-selective agonistic drug with high affinity to D2-like receptors and with much lower affinities to D1-like, % and ol2, muscarinic and 5HT 2 receptors. Additionally, Roxindole exerts 5HT uptake inhibition and 5HT1A agonistic effects. The bioavailability of Roxindole has been estimated at 5% due to a high first-pass metabolization. On the other hand, in 14C distribution studies, Roxindole has crossed the blood-brain barrier readily and the brain concentrations at all intervals have been much higher than corresponding plasma levels. In clinical trials, Roxindole ‘s antipsychotic efficacy was only modest but it was unexpectedly found to produce potent and rapid antidepressant and anxiolytic effects. However, the clinical development of Roxindole was discontinued.

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.
