Amineptine

Amineptine (trade names Maneon [Italy], Survector [Spain, Italy, Philippines]) is an atypical tricyclic antidepressant that selectively inhibits the reuptake of dopamine and to a lesser extent norepinephrine, thus exerting a powerful and fast-acting antidepressant effect.

Introduced in France in 1978 by the pharmaceutical giant Servier and marketed under the trade name Survector, amineptine soon gained a reputation for abuse due to its short-lived, but pleasant, stimulant effect experienced by some patients. (This is to be distinguished from its antidepressant effect, which appears in approximately 7 days after commencing treatment.) This led to the Food and Drug Administration suspending the marketing authorisation for Survector in 1999 and France withdrew it from the market, however several developing countries continued to produce it up until 2005.

Currently amineptine is off-patent and very difficult to obtain. Rare cases of hepatotoxicity, some serious, have been reported, but these were thought to be due to a genetic predisposition.

Approved
Amineptine was approved in France for severe clinical depression of endogenous origin in 1978.

Unapproved/Off-Label/Investigational
Parkinson's Disease, amotivational syndromes, ADHD (Attention Deficit/Hyperactivity Disorder)

Mechanism of action

 * Inhibitor of the reuptake of norepinephrine and dopamine.
 * Little anticholinergic or antihistaminic effects.

Dermatological
Severe acne due to amineptine was first reported in 1988 by various authors&mdash;Grupper, Thioly-Bensoussan, Vexiau, Fiet, Puissant, Gourmel, Teillac, Levigne, to name a few&mdash;simultaneously    in the same issue of Annales de Dermatologie et de Venereologie and in the 12 March 1988 of The Lancet. A year later, Dr Martin-Ortega and colleagues in Barcelona, Spain reported a case of "acneiform eruption" in a 54-year-old woman whose intake of amineptine was described as "excessive." One year after that, Vexiau and colleagues reported six women, one of whom never admitted to using amineptine, getting severe acne concentrated in the face, back and thorax, the severity of which varied with the dosage. Most of them were treated unsuccessfully with isotretinoin (Accutane®) for about 18 months; two of the three that discontinued amineptine experienced a reduction in cutaneous symptoms, with the least affected patient going into remission.

This can be seen as a general side effect of central dopamine enhancement, due to the inhibitory effect of dopamine on prolactine, with the subsequent increase in testosterone output, leading in turn to the same potential for acne as is typical of pubescents.

Psychiatric
Psychomotor excitation can very rarely occur with this drug.
 * Nervousness (very rare)
 * Irritability (very rare)
 * Insomnia (very rare)
 * Suicidal ideation (very rare) Seen in beginning of treatment. By lifting of psychomotor inhibition. Increase monitoring at the beginning of treatment.

Cardiovascular

 * Vasomotor episode (very rare)
 * Arterial hypotension (very rare)
 * Palpitations (very rare)

Hepatic
Amineptine can very rarely cause hepatitis, of the cytolytic, cholestatic varieties. Amineptine-induced hepatitis, which is sometimes preceded by a rash, is believed to be due to an allergic reaction. It resolves upon discontinuation of the offending drug. The risk of getting this may or may not be genetically determined.

Additionally, amineptine is known to rarely elevate transaminases, alkaline phosphatase, and bilirubin.

Mixed hepatitis, which is very rare, generally occurs between the 15th and 30th day of treatment. Often preceded by sometimes intense abdominal pains, nausea, vomiting or a rash, the jaundice is variable. Hepatitis is either of mixed type or with cholestatic prevalence. The evolution was, in all the cases, favorable to the discontinuation of the drug. The mechanism is discussed (immunoallergic and/or toxic).
 * Concours Med 1982; 104:5733-5734.

In circa 1994 Spain, there was a case associating acute pancreatitis and mixed hepatitis, after three weeks of treatment.

Lazaros and colleagues at the Western Attica General Hospital in Athens, Greece reported two cases of drug induced hepatitis 18 and 15 days of treatment.

One case of cytolytic hepatitis occurred after ingestion of only one tablet.

Gastrointestinal

 * Acute pancreatitis (very rare) A case associating acute pancreatitis and mixed hepatitis after three weeks of treatment.

Immunological
In 1989, Sgro and colleagues at the Centre de Pharmacovigilance in Dijon reported a case of anaphylactic shock in a woman who had been taking amineptine.

Effects on the unborn child

 * Non-teratogenic in animals
 * Lacking information in humans

Abuse and Dependence
The risk of addiction is low, but it is there nonetheless. Between 1978 and 1988, there were 186 cases of amineptine addiction reported to the French Regional Centres of Pharmacovigilance; an analysis of 155 of those cases found that they were predominantly female, and that two-thirds of cases had known risk factors for addiction. However, a 1981 study of known opiate addicts and schizophrenia patients found no drug addiction in any of the subjects. In a 1990 study of eight amineptine dependence cases, the gradual withdrawal of amineptine could be achieved without problems in six people; in two others, anxiety, psychomotor agitation, and/or bulimia appeared.

Contraindications
