Loprazolam is a hypnotic drug which stimulates GABA-A receptors. Due to its hypnotic activity the drug is used to treat short-term sleep disordes.

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

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.

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

Mechlorethamine Oxide was approved by the FDA in 1949 for the treatment of hematologic malignancies, alkylating agents are the oldest class of anticancer agents. A biologic alkylating agent exerts its cytotoxic effects by forming DNA adducts and DNA interstrand crosslinks, thereby inhibiting rapidly proliferating cells. Mechlorethamine Oxide is an antineoplastic agent used to treat Hodgkin desease and Lymphoma. Known under the brand names of Mustargen and Valchlor in USA. The FDA granted marketing approval for the orphan drug Valchlor (mechlorethamine) gel on August 23, 2013 for the topical treatment of stage IA and IB mycosis fungoides-type cutaneous T-cell lymphoma (CTCL) in patients who have received prior skin-directed therapy. Each tube of Valchlor contains 0.016% of mechlorethamine which is equivalent to 0.02% mechlorethamine HCL.

Manidipine is a lipophilic, third-generation dihydropyridine calcium channel antagonist with a high degree of selectivity for the vasculature, thereby inducing marked peripheral vasodilation with negligible cardiodepression. In addition, manidipine does not significantly affect norepinephrine levels, suggesting a lack of sympathetic activation. It has a gradual onset of action and a long duration of action enabling once daily administration. Furthermore, manidipine dilates both the efferent and the afferent renal arterioles and appears to have beneficial renal effects unrelated to its antihypertensive effect. Once-daily oral manidipine is an effective and generally well tolerated antihypertensive agent for younger and elderly adult patients with mild-to-moderate hypertension. In particular, in a large double-blind trial, the incidence of ankle oedema was significantly lower in manidipine than in amlodipine recipients. Manidipine is also effective in hypertensive patients with comorbidities, such as type 2 diabetes mellitus and/or renal impairment, and appears to improve insulin sensitivity without affecting metabolic function. Thus, manidipinerepresents a first-line treatment option for patients with essential mild-to-moderate hypertension.

BQ-788, a selective endothelin (ET) B-receptor antagonist, was developed by Banyu. This compound is widely used to demonstrate the role of ET-1 and ET(B) receptor subtypes in physiological and/or pathophysiological conditions. BQ-788 was studied against hypertension. However, this study was discontinued. Besides, was shown that BQ788 could protect against brain edema by inhibiting vascular endothelial growth factor-A-mediated decrease in claudin-5. The intralesional applications of BQ788 were well tolerated and showed signs of directly and indirectly reducing the viability of melanoma cells.

Talcalcitol is a synthetic analogue of vitamin D3. Tacalcitol has been developed by Teijin in Japan with the aim of maintaining the potent cell-regulating properties of calcitriol without the calcium-related adverse effects. Tacalcitol differs structurally from calcitriol by hydroxylation in the 24 position instead of the 25 position. Tacalcitol can influence the principal pathogenetic factors of psoriasis by inducing normalisation of keratinocyte differentiation, performing an anti-proliferative action and finally modulating the inflammatory response. Tacalcitol has been launched as an ointment formulation for the treatment of psoriasis in various countries. High-dose formulations (ointment and lotion) are available in Japan.

Talastine (trade name Ahanon), an alkylamine H1-antihistamine, was studied as a reason for an allergic drug exanthema.

Eptazocine is an opioid analgesic which was introduced in 1987 by Morishita in Japan . It acts as a mixed κappa opioid receptor agonist and mu-opioid receptor antagonist.
