Naphthalene is a crystalline aromatic hydrocarbon usually obtained by distillation of coal tar. Once used as a moth repellent, it is now important as a reactant in the production of phthalic anhydride, which in turn is used for making plasticizers, alkyd resins, and polyester resins. Other fumigant uses of naphthalene include use in soil as a fumigant pesticide, and in attic spaces to repel animals. In the past, naphthalene was administered orally to kill parasitic worms in livestock. In humans, exposure to large amounts of naphthalene may damage or destroy red blood cells. Humans, particularly children, have developed this condition after ingesting mothballs or deodorant blocks containing naphthalene. Some of the symptoms of naphthalene poisoning are fatigue, lack of appetite, restlessness, and pale skin. Exposure to large amounts of naphthalene may also cause nausea, vomiting, diarrhea, blood in the urine, and jaundice (yellow coloration of the skin).

2,4,6-Tribromo-m-cresol (Tribromometacresol), an a hydroxytoluene, is an antifungal agent. It was used for the treatment of dermatomycoses.

Clostebol acetate (4-chloro-testosterone acetate), an anabolic androgenic agent used for fattening purposes in cattle breeding or applied topically in ophthalmological and dermatological treatments. The European Commission has prohibited its use since 1986.

Methadyl Acetate is a narcotic analgesic with a long onset and duration of action. Methadyl Acetate is primarily a mu-type opioid receptor agonist and the drug decreases a patient's opioid use by preventing opioid withdrawal. Levacetylmethadol, the enantiomer of Methadyl Acetate, was approved in 1993 by the U.S. Food and Drug Administration for use in the treatment of opioid dependence. In 2001, levacetylmethadol was removed from the U.S. market due to reports of life-threatening ventricular rhythm disorders.

Cafedrine, also known as norephedrinoethyltheophylline, is a chemical linkage of norephedrine and theophylline and is a cardiac stimulant used to increase blood pressure in people with hypotension. There are few data available for cafedrine. Cafedrine has a half-life of 60 min following both oral and intravenous administration Cafedrine is metabolized to norephedrine and several minor metabolites, but nearly 90% of the administered norephedrine is excreted via the kidneys, mostly unchanged, within 24 h. The effects of cafedrine on cardiac output are believed to be mediated via β- adrenoceptors. Cafedrine has a positive inotropic effect in humans, and this can be abolished by administration of the non-selective β-adrenoceptor antagonist propranolol. A combination of cafedrine and theodrenaline called Akrinor® is used for the treatment of hypotension in adults that occurs during emergency situations, general anesthesia, and regional anesthesia, especially during cesarean sections. Cafedrine/theodrenaline may have advantages over other vasopressor drugs. For example, it can be administered via bolus while catecholamines normally need to be diluted and administered via syringe pumps. Bolus injection is faster, which may be beneficial in emergency situations, plus it is more cost efficient with respect to the disposables. Cafedrine/theodrenaline has been widely used in Germany since 1963

Imidapril (Tanatril), through its active metabolite imidaprilat, acts as an ACE inhibitor to suppress the conversion of angiotensin I to angiotensin II and thereby reduce total peripheral resistance and systemic blood pressure (BP). In clinical trials, oral imidapril was an effective antihypertensive agent in the treatment of mild to moderate essential hypertension. Some evidence suggests that imidapril also improves exercise capacity in patients with chronic heart failure (CHF) and reduces urinary albumin excretion rate in patients with type 1 diabetes mellitus. Imidapril was well tolerated, with a lower incidence of dry cough than enalapril or benazepril, and is a first choice ACE inhibitor for the treatment of mild to moderate essential hypertension.

Chloroprednisone acetate is the 21-acetate ester of chloroprednisone. Chloroprednisone acetate was sold under the brand name Topilan as an anti-inflammatory agent.

Deprodone is a steroid that was approved in Japan for the treatment of inflammatory skin disorders. The drug is marketed under the name Eclar and contains 0.3% of the prodrug, deprodone propionate.

Zuclopenthixol is indicated the management of the manifestations of schizophrenia and other mental illnesses with disturbances in thinking, emotional reactions and behaviour. It is also used to treat the manic phase of manic depressive illness. Zuclopenthixol, a thioxanthene derivative, has high affinity for both dopamine D1 receptors and dopamine D2 receptors. Zuclopenthixol also has high affinity for α1-adrenergic and 5-HT2 receptors. Zuclopenthixol (CLOPIXOL®) is avavilable in the form of tablets and solution for intramuscular injections.

Sarpogrelate (brand name Anplag; former developmental code names MCI-9042, LS-187,118) is a drug which acts as an antagonist at the 5HT2A and 5-HT2B receptors. It blocks serotonin-induced platelet aggregation and has applications in the treatment of many diseases including diabetes mellitus, Buerger's disease, Raynaud's disease, coronary artery disease, angina pectoris, and atherosclerosis.
