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.

Oxyfedrine, an amino ketone derivative and partial agonist at beta receptors, has been shown to have potent antianginal properties and to increase coronary blood flow in normal and ischemic myocardial regions.

BENFURODIL, a 5-benzofuran derivative, is an arterioleptic drug used in the treatment of different arteriopathies.

Imidapril (Tanatril), through its active metabolite imidaprilat, acts as an ACE inhibitor to suppress the conversion of angiotensin I to angiotensin II and thereby reduce total peripheral resistance and systemic blood pressure (BP). In clinical trials, oral imidapril was an effective antihypertensive agent in the treatment of mild to moderate essential hypertension. Some evidence suggests that imidapril also improves exercise capacity in patients with chronic heart failure (CHF) and reduces urinary albumin excretion rate in patients with type 1 diabetes mellitus. Imidapril was well tolerated, with a lower incidence of dry cough than enalapril or benazepril, and is a first choice ACE inhibitor for the treatment of mild to moderate essential hypertension.

Delapril is a lipophilic nonsulfhydryl angiotensin-converting enzyme (ACE) inhibitor, which has been shown to exert potent ACE inhibitory activity and is marketed as an antihypertensive drug. Delapril has been shown to exist in solution as a mixture of s-cis and s-trans conformational isomers, as a result of restricted rotation about the amide bond.

Cinnarizine is a piperazine derivative with antihistaminic, antiserotonergic, antidopaminergic, and calcium channel-blocking activities. It inhibits calcium translocation across the vestibular sensory cells in the ampullae and maintains endolymph flow by preventing constriction of the stria vascularis. It is currently used for the treatment of nausea, vomiting, and vertigo caused by Meniere’s disease and other vestibular disorders. Cinnarizine is also used for prevention and treatment of motion sickness. Chronic use of cinnarizine may induce extrapyramidal symptoms.

Chromonar is a coronary vasodilator agent, it dilates coronary vessels and increases coronary blood flow volume rate, contributes to the development of collateral circulation (with prolonged use), improves metabolic processes in myocardium. The mechanism of action of a role played by its inhibitory effect on phosphodiesterase, accompanied by accumulation in the cells of cyclic 3 ', 5'-adenosine monophosphate. Due to the relatively low therapeutic efficacy Chromonar use is limited, mainly in the early stages of coronary heart disease with angina pectoris in the absence of long-standing and long strokes, when there is no expressed stenotic process.

Dimethylaminoethyl reserpilinate is reserpilinate derivative with hypotensive activity. Given subcutaneously to rats in doses 200 mg/kg dimethylaminoethane reserpilinate increased very slightly the gastric motility but showed no ulcerogenic effect.

Tedisamil is an antiarrhythmic with additional anti-ischaemic properties, which acts via potassium channel blockade. This drug can be categorised as a class III antiarrhythmic agent due to its effects of action potential and QT interval prolongation in these patients. Although tedisamil has been shown to be an effective anti-ischaemic agent, with Phase III trials for angina pectoris now completed, the company are now pursuing the use of tedisamil for the treatment of atrial fibrillation, for which tedisamil is still in Phase II/III clinical trials. The FDA’s Cardiovascular and Renal Drugs Advisory Committee voted not to recommend approval for Solvay Pharmaceuticals’ investigational anti-arrhythmic drug Pulzium (Tedisamil) and asked the company to give the FDA more information.
