Parsidol · ethopropazine hydrochloride · profenamine

Profenamine (INN, trade names Parsidol, Parsidan, Parkin), also known as ethopropazine (BAN), is a phenothiazine derivative used as an antiparkinsonian agent that has anticholinergic, antihistamine, and antiadrenergic actions. It is also used in the alleviation of the extrapyramidal syndrome induced by drugs such as other phenothiazine compounds, but, like other compounds with antimuscarinic properties, is of no value against tardive dyskinesia.

nicergoline (27848-84-6)

Nicergolin neuraxpharm · ergobel · Krewel Brand of Nicergoline

Nicergoline (INN, marketed under the trade name Sermion) is an ergot derivative used to treat senile dementia and other disorders with vascular origins. It decreases vascular resistance and increases arterial blood flow in the brain, improving the utilization of oxygen and glucose by brain cells. It has similar vasoactive properties in other areas of the body, particularly the lungs.

Ketanserin (83846-83-7, 74050-98-9)

R 41468 · R-41468 · R-41,468

Ketanserin (INN, USAN, BAN) (brand name Sufrexal; former developmental code name R41468) is a drug used clinically as an antihypertensive agent and in scientific research to study the serotonin system; specifically, the 5-HT2 receptor family. It was discovered at Janssen Pharmaceutica in 1980.

Pipamperone (1893-33-0)

R 3345 · Dipiperon · 1'-(3-(4-fluorobenzoyl)propyl)-(1,4'-bipiperidine) -4'-carboxamide

Pipamperone (INN, USAN, BAN), also known as carpiperone and floropipamide or fluoropipamide, and as floropipamide hydrochloride (JAN), is a typical antipsychotic of the butyrophenone family used in the treatment of schizophrenia. It is or has been marketed under brand names including Dipiperon, Dipiperal, Piperonil, Piperonyl, and Propitan. Pipamperone was discovered at Janssen Pharmaceutica in 1961, and entered clinical trials in the United States in 1963.

MELPERONE (3575-80-2)

Melperone (Bunil (PT), Buronil (AT, BE, CZ, DK, FL†, NL†, NO†, SE), Eunerpan (DE)) is an atypical antipsychotic of the butyrophenone chemical class, making it structurally related to the typical antipsychotic haloperidol. It first entered clinical use in 1960s.

Pizotifen (15574-96-6)

Sandomigran · Pizotyline · BC 105

Cyamemazine (3546-03-0)

cyamamazine · 10-(3-dimethylamino-2-methylpropyl)phenothiazine-2-carbonitrile · cyamepromazine

Cyamemazine (Tercian), also known as cyamepromazine, is a typical antipsychotic drug of the phenothiazine class which was introduced by Theraplix in France in 1972 and later in Portugal as well. It is used for the treatment of schizophrenia and, especially, for psychosis-associated anxiety, due to its unique anxiolytic efficacy. Cyamemazine differs from other phenothiazine neuroleptics in that aside from the usual profile of dopamine, α1-adrenergic, H1, and mACh receptor antagonism, it additionally produces potent blockade of several serotonin receptors, including 5-HT2A, 5-HT2C, and 5-HT7.

WB-4101 (613-67-2)

WB-4101 is a compound which acts as an antagonist at the α1B-adrenergic receptor. It was one of the first selective antagonists developed for this receptor and was invented in 1969, but is still commonly used in research into adrenergic receptors, especially as a lead compound from which to develop more selective drugs.
