Ibopamine is the prodrug of epinine or N-methyl dopamine. Ibopamine stimulates the DA1 and DA2 dopaminergic receptors, the beta 1 and beta 2 adrenoceptors, and the alpha 1 and alpha 2 adrenoceptors. Ibopamine has varying degrees of affinity for these various families, being the highest for the dopamine receptors and the lowest for the alpha adrenergic receptors. Ibopamine reduces systemic vascular resistance, increases cardiac output, and increases renal flow. Ibopamine also modulates the neuroendocrine reflexes in heart failure; plasma renin activity and norepinephrine and aldosterone plasma concentrations are reduced, both immediately and during sustained administration. In patients with heart failure (HF), low doses appear to exert beneficial neurohormonal, hemodynamic, and renal effects, without increased inotropic effects. However, at higher doses (> 200 mg) ibopamine exerts effects that do not appear to be clinically useful in long-term treatment of chronic HF. Several small trials have suggested a benefit of ibopamine on exercise performance in patients with mild to moderate HF. On the basis of these studies, ibopamine is now being used in Europe to treat patients with mild to moderate congestive heart failure (CHF). At doses of 100 or 200 mg/t.i.d., there has been no evidence of significant safety problems. Ibopamine was used in Europe to treat heart failure. In 1995, a study showed that ibopamine increased death rates in patients who had moderate to severe heart failure. In September 1995, doctors and pharmacists in the Netherlands were officially notified that ibopamine should be used only in patients with mild heart failure. Moreover, the official recommendations for when to use ibopamine were changed according to whether patients had mild or severe heart failure. Ibopamine, a sympathomimetic drug, is used in ophthalmology. t has a not-cycloplegic mydriatic activity. Its peak of action is at 45 minutes after instillation in the conjunctival sac. Its action lasts after about 360 minutes. Its D1-dopaminergic stimulation increases the aqueous humor production and it is a provocative test for evaluating the function of aqueous humor outflow structures also in relatives of glaucomatous patients. It is also useful to treat ocular hypotension. Its main use is in every ophthalmological assessment, either diagnostic or preoperative, where the cycloplegia is not adviced. It is useful for the safe mydriasis of patients treated with α-1 adrenergic receptor antagonists.

Moxisylyte, also known as thymoxamine, is a drug used in urology for the treatment of erectile dysfunction, also was studied, that this drug may be useful to treat ocular disorders such as diabetic retinopathy. It is an alpha1-adrenergic antagonist. Was developed for self-injection therapy in France and marketed in several European countries as Icavex. In the spring 2005 the manufacturer of Icavex decided to withdraw this drug from Europe market, presumable due to its low market shares.

Bromhexine is used for conditions where there are a lot of thick mucus in the airways. Bromhexine acts on the mucus at the formative stages in the glands, within the mucus-secreting cells. Bromhexine disrupts the structure of acid mucopolysaccharide fibres in mucoid sputum and produces a less viscous mucus, which is easier to expectorate. In addition, bromhexine has antioxidant properties. Occasional, mild side effects include: a feeling of fullness in the stomach (bloatedness), diarrhea, dizziness, headache, indigestion, nausea, sweating and skin rashes. Bromhexine may increase the concentration of concurrently administered antibiotics in bronchial secretions. No clinically relevant interactions with other medications have been reported.

Ammonium hexafluorosilicate is a white crystalline solid. Corrodes aluminum. Used as a disinfectant, in etching glass, metal casting, and electroplating. Ammonium hexafluorosilicate is useful for the treatment of dentin hypersensitivity, since ammonium hexafluorosilicate induced calcium phosphate precipitation from the saliva; therefore, it has a continuous effect on dentin tubules occlusion under a simulated oral environment. Ammonium hexafluorosilicate has been applied to arrest caries without discoloration. The major use of sodium hexafluorosilicate and fluorosilicic acid is as fluoridation agents for drinking water. Sodium hexafluorosilicate has also been used for caries control as part of asilicophosphate cement, an acidic gel in combination with monocalcium phosphate monohydrate,and a two-solution fluoride mouth rinse. Both chemicals are also used as a chemical intermediate (raw material) for aluminum trifluoride, cryolite (Na3AlF6), silicon tetrafluoride,and other fluorosilicates and have found applications in commercial laundry. Other applications for sodium hexafluorosilicate include its use in enamels/enamel frits for china and porcelain, in opalescent glass, metallurgy (aluminum and beryllium), glue, ore flotation, leather and wood preservatives, and in insecticides and rodenticides. It has been used in the manufacture of pure silicon, as a gelling agent in the production of molded latex foam, and as afluorinating agent in organic synthesis to convert organodichlorophosphorus compounds to the corresponding organodifluorophosphorus compound. In veterinary practice, external applicationof sodium hexafluorosilicate combats lice and mosquitoes on cattle, sheep, swine, and poultry, and oral administration combats roundworms and possibly whipworms in swine and prevents dental caries in rats. Apparently, all pesticidal products had their registrations cancelled or they were discontinued by the early 1990s

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.

Cetraxate is an oral gastrointestinal medication, mucosal protectant. Cetraxate might indirectly stimulate capsaicin-sensitive afferent nerves and increase mucosal blood flow, and that this may be a key mechanism underlying its gastroprotective action. Cetraxate prevents gastric mucosal blood flow decrease in H. pylori-infected patients. It is usually used to improve gastric mucosal lesion in acute gastritis or acute exacerbation of chronic gastritis and to treat gastric ulcer. The most commonly reported adverse reactions include constipation, rash, nausea, vomiting, dry mouth and diarrhea.

Gestonorone is a progesterone analogue indicated for the treatment of benign prostatic hyperplasia and endometrial cancer. The drug is approved in many countries and used under the names Primostat and Depostat.

Azacosterol (Ornitrol, 20,25-diazacholesterol dihydrochloride, SC 12937) is a cholesterol-lowering drug (hypocholesteremic) which was marketed previously but has since been discontinued. Azacosterol is a sterol derivative of cholesterol with two nitrogen atoms replacing two carbon atoms that acts as a hypocholesteremic agent by blocking delta-24-reductase. Azacosterol has the unintended side effect of causing myotonia. It is an avian contraceptive compound, which reduces fertility by inhibiting cholesterol synthesis. Azacosterol is also useful in the control of rodent populations.

Celiprolol is beta blocker, used to treat high blood pressure. Celiprolol is a selective β1 receptor antagonist, β2 receptor partial agonist. Celiprolol is not approved by the FDA, but is available worldwide under brand names Cardem, Selectol, Celipres, Celipro, Celol, Cordiax, Dilanorm. It is used to treat mild to moderate hypertension and angina prectoris. In 2010 celiprolol has demonstrated positive results in the prevention of vascular complications of Ehlers-Danlos syndrome. Celiprolol has fewer CNS-related side effects than other beta blockers presumably because of limited penetration through blood-brain barrier because of its solubility.

Hymecromone (4-methylumbelliferone) is already approved drug in Europe and Asia where it is used to treat biliary spasm. It is used as choleretic and antispasmodic drugs and as a standard for the fluorometric determination of enzyme activity. The concomitant administration of Hymecromone with products, containing metoclopramide, leads to mutual decrease of their action. Due to a danger of diarrhea with subsequent hypokalemia, Hymecromone should be applied with caution to patients on cardiac glycosides therapy (in these cases the sensitivity to them is increased). Hymecromone can be administered simultaneously with otherspasmolytics and analgesics. Very rare allergic reactions, itching, erythema, rashes; diarrhea which normally disappears by reduction of dose or discontinuance of therapy.
