Alprenolol is a beta adrenoreceptor blocking agent and 5HT1A antagonist, developed by AstraZeneca and now available as generic drug. It is used for treatment of hypertension, angina pectoris due to coronary atherosclerosis and acute myocardial infarction.

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.

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from 1996, but its marketing authorization was suspended by the European Medicines Agency in 1998 and the drug was withdrawn from the market.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.

Xamoterol (ICI 118,587) is a partial agonist of beta1-adrenoceptors. Xamoterol acts on the cardiac beta 1-adrenergic receptor, modifies the response of the heart to variations in sympathetic activity. At rest, it produces modest improvements in cardiac contractility, relaxation, and filling without increase in myocardial oxygen demand. The improvements are maintained during exercise although the attendant tachycardia is attenuated. The beneficial effects of xamoterol on both systolic and diastolic function suggested that it would be effective in patients with mild-to-moderate heart failure, and this was demonstrated in small placebo-controlled studies where effort tolerance and symptoms were improved. Xamoterol produced improvements in exercise capacity, clinical signs, symptoms and quality of life with a low incidence of adverse experiences. Xamoterol is effective as monotherapy in heart failure.

Melperone is an antipsychotic drug which is used in Europe for the treatment of sleep disorders, agitation and confusion states. The exact mechanism of melperone action is unknown.

Benzbromarone (INN) is a uricosuric agent and non-competitive inhibitor of xanthine oxidase used in the treatment of gout, especially when the first line treatment, allopurinol, fails or produces intolerable adverse effects. It is structurally related to the antiarrhythmic amiodarone. Benzbromarone was introduced in the 1970s and was viewed as having few associated serious adverse reactions. It was registered in about 20 countries throughout Asia, South America and Europe. In 2003, the drug was withdrawn by Sanofi-Synthélabo, after reports of serious hepatotoxicity, although it is still marketed in several countries by other drug companies. The withdrawal has greatly limited its availability around the world and increased difficulty in accessing it in other countries where it has never been available. Standard dosages of benzbromarone (100 mg/day) tend to produce greater hypouricaemic effects than standard doses of allopourinol (300 mg/day) or probenecid (1000 mg/day). Adverse effects associated with benzbromarone are relatively infrequent but potentially severe. Four cases of benzbromarone-induced hepatotoxicity were identified from primary literature, and eleven cases have been reported by Sanofi-Synthélabo but details are not available in the public domain. Only one of the four publicly published cases demonstrated a clear relationship between the drug and liver injury as demonstrated by rechallenge. The other three cases lacked incontrovertible evidence to support a diagnosis of benzbromarone-induced hepatotoxicity. If all the reported cases are assumed to be due to benzbromarone, the estimated risk of hepatotoxicity in Europe was approximately 1 in 17 000 patients but may be higher in Japan. Benzbromarone is a very potent inhibitor of CYP2C9. The mechanism of benzbromarone hepatotoxicity is believed to be due to its hepatic metabolism by CYP2C9 and possible effects of the parent compound or its metabolites on mitochondrial function. Benzbromarone is a benzofuran and shares structural similarities with benzarone and amiodarone, all three of which affect mitochondrial function.

Ebastine is an antihistamine which blocks H1-receptors through its carboxylic acid metabolite. Ebastine is indicated for the treatment of allergic rhinitis and chronic idiopathic urticaria.

Rimonabant (also known as SR141716; trade names Acomplia, Zimulti) was an anorectic antiobesity drug that was first approved in Europe in 2006 but was withdrawn worldwide in 2008 due to serious psychiatric side effects. Rimonabant is an inverse agonist for the cannabinoid receptor CB1 and was the first drug approved in that class. There is considerable evidence that the endocannabinoid (endogenous cannabinoid) system plays a significant role in appetitive drive and associated behaviors. It is, therefore, reasonable to hypothesize that the attenuation of the activity of this system would have therapeutic benefit in treating disorders that might have a component of excess appetitive drive or over-activity of the endocannabinoid system, such as obesity, ethanol and other drug abuse, and a variety of central nervous system and other disorders. Data from clinical trials submitted to regulatory authorities showed that rimonabant caused depressive disorders or mood alterations in up to 10% of subjects and suicidal ideation in around 1%, and in Europe, it was contraindicated for people with any psychiatric disorder, including depressed or suicidal people. Additionally, nausea and upper respiratory tract infections were very common (occurring in more than 10% of people) adverse effects; common adverse effects (occurring in between 1% and 10% of people) included gastroenteritis, anxiety, irritability, insomnia and other sleep disorders, hot flushes, diarrhea, vomiting, dry or itchy skin, tendonitis, muscle cramps and spasms, fatigue, flu-like symptoms, and increased risk of falling.

Roquinimex (Linomide, LS 2616) is a quinoline-3-carboxamide with pleiotropic immune modulating capacity and it has therapeutic effects in several experimental animal models of autoimmune diseases. Linomide has been evaluated in clinical trials for multiple sclerosis, and was indeed shown to have disease inhibitory effects. However, due to unexpected side effects recorded in patients treated with Linomide, premature termination of clinical trials was required. The basic mechanism(s) of action of Linomide in inducing beneficial effects in autoimmune diseases is still elusive. Some experimental evidence indicates that Linomide influences the regulation of the cytokine profile, resulting in the inhibition of autoimmune and inflammation pathologies. Roquinimex possesses potential antineoplastic activity. Roquinimex inhibits endothelial cell proliferation, migration, and basement membrane invasion; reduces the secretion of the angiogenic factor tumor necrosis factor alpha by tumor-associated macrophages (TAMs); and inhibits angiogenesis. Roquinimex was in phase III clinical trials with Pharmacia Corporation in Europe and the US for the treatment of multiple sclerosis.

Amithiozone, also known as thioacetazone, is an oral antibiotic, which is used in the treatment of tuberculosis. In 1991, the World Health Organization (WHO) recommended replacing thioacetazone with ethambutol in patients with known or suspected HIV infection. Thioacetazone is no longer included in WHO’s recommended first-line treatment for tuberculosis and is now reserved for uncommon situations in which treatment options have been compromised by resistance to other anti-tuberculosis medicines in HIV-negative individuals. Despite the increased recognition of this risk, thioacetazone remained in use mainly in low-income countries because of its low cost. Amithiozone has also been used in trials studying the treatment of Mycobacterium Avium-intracellular Infection. One of the possible mechanism action of the drug is interference with the metabolism of methionine of susceptible tubercle bacilli, which utilize methionine for nucleic acid synthesis.
