Enoximone is an inhibitor of PDE3, which is used for the treatment of congestive heart failure. Also enoximone was shown to inhibit PDH in cardiac myocytes. The inhibition was shown to occur secondary to stimulating fatty acid oxidation

Lercanidipine is antihypertensive drugs which acts by blocking L-type calcium channels, allowing relaxation and opening of blood vessels. Lercanidipine exists as a racemate, with anti-hypertensive activity residing primarily in S-enantiomer. NDA for lercanidipine was submitted to FDA in 2002 by Forest Laboratories, but FDA refused to approve the drug, and lercanidipine is not marketed in USA. Lercanidipine is also investigated in preclinical models of epilepsy and ischemic stroke.

Lorcainide is a class Ic antiarrhythmic medication. It was reported to be highly efficient for the treatment of ventricular arrhythmias, ventricular fibrillation, and tachycardia. The drug was used under the name Remivox. The mechanism of lorcainide action involves the blockage of sodium channels. Lorcainide was withdrawn from the market for a commercial reason, but later it was admitted that the use of the drug is associated with high risk of death.

Bamethan (butyl-sympatol or vasculat) is an adrenaline derivative developed by C. H. Boehringer Sohn. Bamethan shows a depressor action on peripheral blood vessels as a result of the peripheral vasodilating action caused by stimulation of adrenergic beta-receptor. Bamethan has been used abroad in the treatment of certain peripheral vascular and circulatory disturbances, such as vasospastic conditions, arteriosclerotic peripheral vascular disease, Raynaud's syndrome, occlusive vascular disease of the legs, the post-thrombotic syndrome, degenerative muscular disorders, and other conditions involving peripheral vascular insuffciency.

Pentifylline is an active vasodilating substance which does not affect blood sugar levels. Pentifylline inhibits the soluble and the particulate cyclic AMP phosphodiesterases from bovine platelets and rat brain ATPase. The inhibition of ATPase by pentifylline was not influenced by the change in Na /K ratio. Pentifylline in combination with Nicotinic acid indicated for the treatment of Cerebral circulatory disorders and Circulatory disorders of the eye. Pentifylline is well tolerated but it is recommended that blood pressure be monitored and if there is a severe drop in blood pressure, a drip infusion of plasma expander be administered. Coagulation states should also be closely watched.

Bamidipine is an antihypertensive drug belonging to the dihydropyridine (DHP) group of calcium antagonists. The product was originally developed by Yamanouchi Pharmaceutical (Tokyo, Japan) and is currently marketed in Japan under the trade name of Hypoca (Astellas Pharma Inc, Tokyo, Japan). It is available in a modified-release formulation which has a gradual onset of action and is effective in a single daily oral dose of 10 to 20 mg. Bamidipine has selective action against cardiovascular calcium antagonist receptors and its antihypertensive action is related to the reduction of peripheral vascular resistance secondary to its vasodilatory action. The clinical antihypertensive efficacy of barnidipine is similar to that of other DHP calcium antagonists such as nitrendipine and amlodipine, and antihypertensives belonging to other drug classes such as atenolol and enalapril. Barnidipine has been found to be as efficacious and well tolerated as hydrochlorothiazide in the management of hypertension in elderly patients. Barnidipine is generally well tolerated. As with other DHP calcium antagonists, vasodilator adverse events such as headache, flushing and peripheral oedema account for most of the adverse events reported with its use and are usually transient. Oedema is less frequent than with amlodipine and nitrendipine. Its use is not associated with reflex tachycardia.

Tiadenol (2,2'-(decamethylenedithio)-diethanol) exrets hepatic peroxisome proliferative activity, it induces peroxisomal enzymes and peroxisome proliferation. Tiadenol is known for its hypolipidemic properties.

Octopamine is an organic chemical closely related to norepinephrine. In many types of invertebrates it functions as a neurotransmitter. Octopamine is known to exert adrenergic effects in mammals although specific octopamine receptors have been cloned only in invertebrates. It has been shown that octopamine can stimulate alpha(2)-adrenoceptors (ARs) in Chinese hamster ovary cells transfected with human alpha(2)-ARs. Octopamine stimulates lipolysis through beta(3)-rather than beta(1)-or beta(2)-AR activation in white adipocytes from different mammalian species. Octopamine activates only beta(3)-ARs and is devoid of alpha(2)-adrenergic agonism. Thus, octopamine could be considered as an endogenous selective beta(3)-AR agonist. In humans Octopamine is a trace amine found endogenously in the human brain where it interacts with signalling of catecholamines; it is structurally similar to synephrine and tyramine, being a metabolite of the latter (via dopamine β-hydroxylase) and substrate for the synthesis of the former (via phenethanolamine N-methyltransferase[3]) while being perhaps the closest in structure to noradrenaline. Octopamine is found in the bitter orange similar to many biogenic amines related to L-tyrosine that are used as dietary supplements, this includes synephrine and hordenine. p-Octopamine HCl (Norphen) was studied in the late 1960’s and 1970’s as a drug for the treatment of hypotensive regulatory and circulatory disorders. Octopamine was used as a nootropic. All optical isomers (enantiomers) of octopamine are on the World Anti-Doping Agency (WADA) 2014 list of substances prohibited in competition.

Clofenamide is a benzenedisulfonamide-based agent and carbonic anhydrase (CA) inhibitor with diuretic activity. Clofenamide inhibits CA, thereby preventing sodium, bicarbonate and thus water reabsorption in the proximal convoluted tubule resulting in diuresis.

Clopamide is a thiazide diuretic which helps in removing fluid from the body. Clopamide is used in treatment of hypertension and edema.
