Bucumolol is a beta-adrenergic antagonist. It can be used in the treatment of myocardial ischemia and hypertension.

Rescimetol (CD-3400) developed by Nippon Chemiphar Co. Ltd., is an antihypertensive agent belonging to the class of rauwolfa alkaloids. CD-3400 was shown to have low toxicity and a weak central action. CD-3400 possessing a sustained antihypertensive activity may be prescribed in cases when long-term therapy is required for hypertensive patients.

Benzoclidine (Oxylidin) exerts tranquilizing and hypotensive actions. It reduces the excitability of the central nervous system, enhances the effect of hypnotic drugs, analgesics and local anesthetics, has a moderate antihypertensive effect, reduces the excitability of the vasomotor centers, has anti-arrhythmic activity. Benzoclidine is marke indicated for the treatment of anxiety and depression of various origins (particularly mild expressed and associated with cerebrovascular insufficiency), neurosis, personality disorder, cyclothymia, hypertension with cerebral disorders, sinus tachycardia, paroxysmal tachycardia.

Todralazine is a hydralazinophthalazine-derived drug currently used in the treatment of arterial hypertension. As vasodilator, it might be used in combination with isosorbide dinitrate. Side effects and drug toxicity were uncommon in such vasodilator therapy.

Omapatrilat is an antihypertensive agent that inhibits both neprilysin (neutral endopeptidase, NEP) and angiotensin-converting enzyme (ACE). The drug was developed for possible use in heart failure and hypertension, but was not approved by the FDA due to angioedema safety concerns.

Potassium magnesium citrate has being proven to be an effective prophylaxis against recurrent calcium oxalate nephrolithiasis. Liquid potassium magnesium citrate has being studied in clinical trial for controlling Hypertension. Provision of alkali as potassium-magnesium citrate is an effective countermeasure for the increased risk of renal stone disease associated with immobilization. Despite an increase in urine calcium concentration, the relative saturation of calcium oxalate decreased due to citrate chelation of calcium and the concentration of undissociated uric acid decreased due to the significant increase in urine pH. Potassium magnesium citrate is a nutritional supplement that fights kidney stones in three different ways. The potassium provided by the supplement raises the pH of the urine, making it more alkaline, thus reducing the amount of calcium that the urine can dissolve. When there is less calcium in the urine, fewer calcium kidney stones can form. The magnesium in the supplement reduces the amount of calcium the kidneys pump out of the body and into the urine. And the citrate in the supplement keeps oxalates dissolved in the urine so they are flushed away before they can form kidney stones.

TZC-5665 (Oberadilol) is a pyridazinone derivative with vasodilatory and beta-adrenergic blocking activities and type III phosphodiesterase inhibitory action

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.

Meticrane is a diuretic. Meticrane is used to treat essential hypertension.

Xibenolol or D-32 (dl-tert-butylamino-3-(2', 3'-dimethylphenoxy)-2-propanol hydrochloride) is a beta-blocking agent. It has been developing as a hypontesive medicine by Kowa Pharmaceutical and Teikoku Hormone, however development has been discontinued.
