Nitrendipine is a calcium channel blocker with marked vasodilator action. It is an effective antihypertensive agent and differs from other calcium channel blockers in that it does not reduce glomerular filtration rate and is mildly natriuretic, rather than sodium retentive. By deforming the channel, inhibiting ion-control gating mechanisms, and/or interfering with the release of calcium from the sarcoplasmic reticulum, nitrendipine inhibits the influx of extracellular calcium across the myocardial and vascular smooth muscle cell membranes. The decrease in intracellular calcium inhibits the contractile processes of the myocardial smooth muscle cells, causing dilation of the coronary and systemic arteries, increased oxygen delivery to the myocardial tissue, decreased total peripheral resistance, decreased systemic blood pressure, and decreased afterload.

Aprindine is a class Ib antiarrhythmic agent. It is not approved in USA, but is available in European countries, where it is used to treat supraventricular and ventricular arrhythmias. Aprindine acts by blocking sodium voltage channels and disrupting interactions between calmodulin and prosphodiesterase.

Atreleuton is a potent, orally administered, selective 5-Lipoxygenase inhibitor. Atreleuton had been in phase III clinical trials for the treatment of asthma and phase II clinical trials for the treatment of acute coronary syndrome and atherosclerosis. However, this research has been discontinued.

Sertindole (brand names: "Serdolect" and "Serlect") is an antipsychotic medication. Sertindole was developed by the Danish pharmaceutical company Lundbeck and marketed under license by Abbott Labs. Like other atypical antipsychotics, it has activity at dopamine and serotonin receptors in the brain. It is used in the treatment of schizophrenia. Sertindole is not approved for use in the United States and was discontinued in Australia in January 2014. In Europe, sertindole was approved and marketed in 19 countries from 1996, but its marketing authorization was suspended by the European Medicines Agency in 1998 and the drug was withdrawn from the market. In 2002, based on new data, the EMA's CHMP suggested that Sertindole could be reintroduced for restricted use in clinical trials, with strong safeguards including extensive contraindications and warnings for patients at risk of cardiac dysrhythmias, a recommended reduction in maximum dose from 24 mg to 20 mg in all but exceptional cases, and extensive ECG monitoring requirement before and during treatment.

Tofisopam (marketed under brand names Emandaxin and Grandaxin) is a 2,3-benzodiazepine derivative that is marketed in several European countries as the anxiolytic drug. Tofisopam does not bind to the benzodiazepine binding site of the gamma-aminobutyric acid receptor. One study has shown that tofisopam acts as an isoenzyme-selective inhibitor of phosphodiesterases (PDEs) with the highest affinity to PDE-4A1 followed by PDE-10A1, PDE-3, and PDE-2A3. Like other benzodiazepines, tofisopam possesses anxiolytic properties but unlike other benzodiazepines, it does not have anticonvulsant, sedative, skeletal muscle relaxant, motor skill-impairing or amnestic properties. While it may not be an anticonvulsant in and of itself, it has been shown to enhance the anticonvulsant action of classical 1,4-benzodiazepines such as diazepam (but not sodium valproate, carbamazepine, phenobarbital, or phenytoin). Tofisopam is not approved for sale in the United States or Canada. However, Vela Pharmaceuticals of New Jersey is developing the D-enantiomer (dextofisopam) as a treatment for irritable bowel syndrome, with moderate efficacy demonstrated in clinical trials so far.

Procaterol is a beta2-adrenoreceptor agonist. It is a bronchodilator that may be administered orally or by aerosol inhalation for the treatment of dyspnea caused by bronchial asthma, chronic bronchitis, and pulmonary emphysema. The drug is not approved in the USA, but is available in Japan, Indonesia, and other countries worldwide.

Evocalcet (MT-4580, KHK7580) is an allosteric calcium-sensing receptor agonist. Evocalcet directly acts on calcium receptors on parathyroid cells to suppress synthesis and secretion of parathyroid hormone (PTH), and it consequently decreases serum PTH and serum calcium. ORKEDIA® TABLETS (generic name: evocalcet, code name: KHK7580) has been listed on the National Health Insurance (NHI) Drug Price List and launched for the treatment of secondary hyperparathyroidism in patients on maintenance dialysis in Japan.

Ripasudil (K-115) is a selective Rho-associated coiled coil-containing protein kinase (ROCK) inhibitor. This compound, which was originally discovered by D. Western Therapeutics Institute, Inc., reduces intraocular pressure (IOP) by directly acting on the trabecular meshwork, thereby increasing conventional outflow through the Schlemm's canal. As a result of this mechanism of action, ripasudil may offer additive effects in the treatment of glaucoma and ocular hypertension when used in combination with agents such as prostaglandin analogues (which increase uveoscleral outflow) and β blockers (which reduce aqueous production). GLANATEC® (Ripasudil hydrochloride hydrate) ophthalmic solution 0.4% is launched in Japan for the treatment of glaucoma and ocular hypertension.

Manidipine, (S)- is enantiomer of Manidipine a lipophilic, third-generation dihydropyridine calcium channel antagonist with a high degree of selectivity for the vasculature, thereby inducing marked peripheral vasodilation with negligible cardiodepression. Manidipine has different pharmacological effects and (S)-manidipine is shown to be about 30–80 times more potent than (R)-manidipine in its antihypertensive action and in the radioligand binding assay. Patch-clamp experiments revealed that the S-enantiomers of manidipine displayed a faster onset of action and produced a greater blockade than the R-enantiomer. Also, manidipine enantiomers have markedly different pharmacokinetics and the S/R ratio for (S)- and (R)-enantiomer concentrations is 2.0
