Vernakalant is a new antiarrhythmic drug that acts selectively in the atrium, targeting atrial specific channels. Vernakalant is an anti-arrhythmic medicine that acts preferentially in the atria by prolonging atrial refractoriness and by rate-dependently slowing impulse conduction. These anti-fibrillatory actions on refractoriness and conduction are thought to suppress reentry, and are potentiated in the atria during atrial fibrillation. The preferential effects of vernakalant on the atria are postulated to result from its block of currents that are expressed in the atria (e.g., the ultra-rapid delayed rectifier potassium current; and the acetylcholine-activated potassium current), but not in the ventricles, as well as the unique electrophysiologic condition of the fibrillating atria. An oral formulation of vernakalant is in phase II development as a long-term maintenance therapy for patients with atrial fibrillation. An intravenous formulation of vernakalant has been launched in most countries in Europe and Latin America, and in Hong Kong, for the acute conversion of atrial fibrillation. The product has been approved for the acute conversion of atrial fibrillation in South Africa, Iceland, Turkey and is awaiting approval for the same indication in Canada. Phase III development of the IV formulation is ongoing at sites in Asia, and development is currently on hold in the US.

Clebopride is a dopamine antagonist drug. It is used to treat functional gastrointestinal disorder such as nausea or vomiting. Unchanged parent drug was the most abundant compound in human urine. Major metabolites included the hydroxylation at benzyl group to yield carbinolamine and its further N-dealkylation product, and the piperidine ring hydroxylation/oxidation metabolite (a lactam).

Itopride is a dopamine D2 receptor antagonist and inhibitor of acetylcholinesterase. It is indicated in the for the treatment of gastrointestinal symptoms caused by reduced gastrointestinal motility, such as functional non-ulcer dyspepsia (chronic gastritis), gastric fullness, rapid satiation, pain or discomfort in the upper abdomen, anorexia, heartburn, nausea, and vomiting. The drug is not approved in the USA or UK but is available in Japan and Western European countries.

Proroxan is a non-selective а-adrenoblocker. Proroxan was found to prevent the development of hypertensive crises and improve cerebral bioelectrical parameters in most of hypertensive patients. Proroxan has been used as an antihypertensive and in the treatment of Ménière’s disease, motion sickness, and allergic dermatitis.

Iodoalphionic acid is the contrast medium, which was used for gallbladder examination. It is rarely appeared in the colon and, therefore, rarely masked the gallbladder. The density of the shadow produced by Iodoalphionic acid was greater than that produced by iodophthalein. It was reliable peroral cholecystographic medium, which was less objectionable to take and seldom causes vomiting. Diarrhoea occurred in some cases, but not more often than with tetraiodophenolphthalein. The ingestion of Iodoalphionic acid resulted in low thyroidal radioiodine accumulation for periods ranging from a few weeks to many months.

Oteracil is an adjunct to antineoplastic therapy, used in combination with Gimeracil and Tegafur. Gimeracil/oteracil/tegafur combination is approved for the gastric cancer treatment. Oteracil is an orotate phosphoribosyltransferase (OPRT) inhibitor that decreases the activity of 5-fluorocil (tegafur is a prodrug of 5-fluorocil) in normal gastrointestinal mucosa.

Piribedil is an antiparkinsonian agent which acts as D2 and D3 receptor agonist. In European countries and worldwide it is used as a monotherapy or in combination with dopatherapy for treatment of Parkinson's disease, cognitive impairment and obliterating arteriopathy.

Zaldaride is a calmodulin antagonist known to produce inhibition of calmodulin-dependent voltage-gated ion channels including those of Ca2 , Na , and K . Zaldaride was also observed to inhibit nicotinic acetylcholine receptor (nAChR) channel currents. Zaldaride has been studied in clinical trials as a potential treatment for travelers diarrhea.

Omoconazole is an azole antifungal drug, is used to treat candidiasis; dermatophytes and Pityriasis Versicolor

Temocapril is a prodrug-type angiotensin-I converting enzyme (ACE) inhibitor not approved for use in the United States but is approved in Japan and South Korea. Temocapril can also be used in hemodialysis patients without risk of serious accumulation.
