Urapidil is an anti-hypertensive agent approved in Europe for the treatment of the corresponding disease. The drug acts by activating 5HT1a receptor and inhibiting alpha1-adrenergic receptors.

Tasosartan is a long-acting angiotensin II (AngII) receptor blocker. Tasosartan is infrequently in the treatment of hypertension and heart failure. The manufacturer withdrew it from FDA review after phase III clinical trials showed elevated transaminases. Tasosartan blocks the renin-angiotensin-aldosterone system (RAAS) at the level of the AT1 receptor that mediates most, if not all, of the important actions of Ang II. Tasosartan binds reversibly to the AT1 receptors in vascular smooth muscle and the adrenal gland. As angiotensin II is a vasoconstrictor, which also stimulates the synthesis and release of aldosterone, blockage of its effects results in decreases in systemic vascular resistance.

Benidipine is an orally triple L-, T-, and N-type calcium channel blocker for the treatment of hypertension and angina pectoris synthesized and developed by Kyowa Hakko Kogyo Co., Ltd. Benidipine, approved in Japan in November 1991, has become one of the three best selling CCBs and is highly useful as a potent, long-lasting antihypertensive and antianginal agent.

Budralazine is a vasodilator. Budralazine is a direct-acting vasodilating agent that does not produce marked tachycardia. Hypotensive effect of Buterazine has being shown. Budralazine is reported as an ingredient of Buterazine in Japan.

Bopindolol (4-[benzoyloxy-3-tertbutylaminopropoxy]-2-methylindole hydrogen malonate) is an indole beta-adrenoceptor antagonist bearing a benzoyl ester residue on the beta-carbon atom of the propanolamine side chain. Bopindolol is metabolized by esterase to benzoic acid and an active metabolite, 18-502 [4-(3-t-butylamino-2-hydroxypropoxy)-2-methyl indole], which is further metabolized to 20-785 [4-(3-t-butylaminopropoxy)-2-carboxyl indole]. Bopindolol produces sustained blockade of beta 1- and beta 2-adrenoceptors, has intrinsic sympathomimetic as well as membrane stabilizing actions, inhibits renin secretion, and interacts with 5-HT receptors. Bopindolol is used in the treatment of hypertension. In limited trials bopindolol has also successfully reduced symptoms in patients with angina pectoris, anxiety and essential tremor.

Marketed under the brand name BYSTOLIC, Nebivolol is indicated for the treatment of hypertension, to lower blood pressure. Nebivolol is a racemic mixture containing equal amounts of two enantiomers, d-nebivolol and l-nebivolol (Levonebivolol). It is a selective β1-adrenergic antagonist with vasodilating properties. The d-enantiomer provides selective β1-adrenergic receptor blockade, whereas l-nebivolol possesses vasodilating properties thought to be attributable to nitric oxide modulation via the L-argininenitric oxide pathway. dl-nebivolol exerts an antithrombotic activity by stimulating the formation of NO by platelets, and that this effect is generated by its l-enantiomer, whereas the d-enantiomer exerts a weak antiplatelet effect because of β-adrenergic receptor-independent stimulation of adenyly cyclase. L-nebivolol had a protective effect against both endothelial dysfunction of the mesenteric artery and ileal injury induced by intestinal I/R; however, similar effects were not observed for racemic nebivolol. d-Nebivolol (SRRR) and nebivolol showed combined high affinity and selectivity for inhibition of beta 1-adrenergic receptor coupled accumulation of cAMP in CHO-Hu beta 1 cells (0.41 and 0.42 nM for d-nebivolol and nebivolol, respectively). l-Nebivolol (RSSS) was 1460 times less potent than d-nebivolol in CHO-Hu beta 1 cells.

Bevantolol (INN) was a drug candidate for angina and hypertension that acted as both a beta blocker and a calcium channel blocker. Animal experiments confirm both agonist and antagonist effects on alpha-receptors, in addition to antagonist activity at beta-1 receptors. By binding and antagonizing beta-1 receptors Bevantolol inhibits the normal normal epinephrine-mediated sympathetic actions such as increased heart rate. This has the effect of decreasing preload and blood pressure. Bevantolol was discovered and developed by Warner-Lambert but in January 1989 the company announced that it had withdrawn the New Drug Application. As of 2016 it wasn't marketed in the US, UK, or Europe.

Zofenopril is an inhibitor of Angiotensin Converting Enzyme (ACE), which is approved in Europe for the treatment of hypertension and acute myocardial infarction.

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.

Proroxan is a non-selective а-adrenoblocker. Proroxan was found to prevent the development of hypertensive crises and improve cerebral bioelectrical parameters in most of hypertensive patients. Proroxan has been used as an antihypertensive and in the treatment of Ménière’s disease, motion sickness, and allergic dermatitis.
