Lidamidine, also known as WHR-1142A and Lidaral, is an alpha2-adrenergic receptor agonist that inhibits intestinal secretion, reduces intestinal transit, and inhibits smooth muscle contraction. Lidamidine hydrochloride is used to treat diarrhoea and other gastrointestinal disorders. Lidamidine’s intestinal antisecretory effects are mediated through the activation of peripheral alpha-2 adrenoceptors. Lidamidine crosses the blood brain barrier poorly and is therefore devoid of the centrally mediated alpha-2 effects that have limited the use of other alpha-2 adrenoceptor agonists in the intestinal tract.

Bucainide is a potent cardiac depressant and antiarrhythmic agent. The antiarrhythmic effect was demonstrated in the following animal models: mouse chloroform-induced ventricular arrhythmias, refractory period prolongation in guinea pig isolated atria, aconitine-induced atrial arrhythmias in the dog, ventricular arrhythmias following coronary artery ligation in the dog, and ouabain-induced ventricular tachyarrhythmias in the dog. The drug also possesses local anesthetic effects and is a weak central nervous system depressant. Studies with the radiolabeled drug in rats and dogs also demonstrated the drug's large volume of distribution, and its initial rapid disappearance from the blood. Tissue distribution studies in the rat after administration of the radiolabeled drug showed that bucainide is rapidly taken up by the tissues.

Trimazosin was originated by Pfizer and was licensed to Bristol-Myers Squibb worldwide except for Canada, Mexico and the USA. Trimazosin is a quinazoline antihypertensive agent structurally related to the selective alpha 1-adrenoceptor blocker prazosin. Trimazosin is an alpha adrenergic receptor antagonist. Compared with prazosin, trimazosin was a less potent but more efficacious hypotensive agent. At doses which caused equal or even greater hypotensive effects than those caused by prazosin, trimazosin caused less inhibition of pressor responses to phenylephrine. When administered during a maximum hypotensive response to prazosin, trimazosin caused an additional fall in pressure. Trimazosin is an effective antihypertensive when given by itself or in combination with a diuretic. Its ability to induce vasodilation without concomitant sodium retention or stimulation of the renin axis may be an important factor in its effectiveness. Trimazosin has the potential to cause sustained improvement in left ventricular function, both at rest and during exercise, in patients with chronic congestive heart failure (CHF).

Mebeverine is an antispasmodic with a direct action on the smooth muscle of the gastrointestinal tract. The exact mechanism of action is not known, but multiple mechanisms, such as a decrease in ion channel permeabilities, blockade of noradrenaline reuptake, a local anesthetic effects, as well as weak anti-muscarinic and phosphodiesterase inhibitory effect might contribute to the local effects of Mebeverine. This medicine is used to treat symptoms of irritable bowel syndrome (IBS) and similar problems such as chronic irritable colon, spastic constipation, mucous colitis and spastic colitis. Most people will not have problems with Mebeverine, but some may get some side effects, such as: difficulty in breathing, swelling of face, neck, tongue or throat, skin rash, red itchy skin.

Alrestatin, an inhibitor of aldose reductase, was studied in clinical trials for the treatment of diabetes. But this study was discontinued, because of the high hepatotoxicity events.

Buformin (1-butylbiguanide) is an oral antidiabetic drug of the biguanide class. AMPK activator. AMPK is a potential therapeutic target in the prevention and the treatment of type 2 diabetes and insulin resistance. Major classes of antidiabetic drugs have been reported to activate AMPK. Buformin exerts its anti-tumorigenic activity via activation of AMPK and inhibition of the mTOR signaling pathways in endometrial cancer cells. Toxicity: guinea pig LD50 subcutaneous 18 mg/kg; mouse LD50 intraperitoneal 140 mg/kg and 300 mg/kg oral. Buformin was withdrawn from the market in many countries due to an elevated risk of causing lactic acidosis.

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.

Lorajmine is a monochloracetyl derivative of ajmaline. It is a class Ia antiarrhythmic agent that is rapidly hydrolyzed to ajmaline by plasma and tissue esterases. Lorajmine was used in the clinic to control arrhythmias. It was found that in a significant proportion of cases administration of lorajmine lead to worsening of arrhythmias.

Flumedroxone is a progestative agent. It is a pregnane derivative substituted at C-6 by a trifluoromethyl group. It was tested whether flumedroxone had prophylactic value in migraine. No benefit was found in males, or in females with no history of menstrual exacerbation of migraine. In women whose migraine was worse around the time of menstruation flumedroxone resulted in statistically fewer headaches of less severity. With the dose used in this trial side-effects were frequent, the commonest being polymenorrhagia, which occurred in half the women of reproductive age.

Antimonic acid is an inorganic acid formed by antimony. As an ion-exchange material crystalline antimonic acid may be used for the regeneration of heteropolyacid catalysts. In addition, as a proton conductor, it may be used for gas sensing.
