Amineptine 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. Developed 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, psychostimulant 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 FDA 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. For example, first degree relatives of patients who suffered hepatotoxicity also experienced the same phenomena. Pharmacological properties 1. PSYCHOSTIMULANT ( principal some ) 2. ANTIDEPRESSANT ( principal some ) 3. NOOTROPIC ( to be confirmed ) Mechanism of action 1. Principal Probably identical to the tricyclic antidepressants. Inhibitor of the reuptake of noradrenalin and dopamine. Little anticholinergic or antihistaminic effects. Primary effects 1. ANTIDEPRESSANT (principal) Therapeutic indications 1. DEPRESSION (principal) of endogenous origin, reactionary or neurotic. Side effects 1. ACNE (SOME) Monstrous iatrogenic form. The gravity of the lesions seems proportional to the amount. Treatment by isotretinoin: - Ann Dermatol Venereol 1988; 115:1177-1179. Severe cases of acne, following the use of large amounts, nine other cases were already reported: - J Dermatol Treat 1994; 5:143-144. A case in a 54 year old woman surdosée: - Int J Dermatol 1996; 35:892-893. 2. DRUG-ADDICTION (SOME) - To prescribe 1990; 10:199. - Therapie 1990; 45:51. 3. VASOMOTOR EPISODE (VERY RARE ) 4. ARTERIAL HYPOTENSION (VERY RARE ) 5. PALPITATIONS (VERY RARE ) 6. NAUSEA (VERY RARE) can precede onset of hepatitis. 7. EPIGASTRIC PAIN (VERY RARE) can precede onset of hepatitis. 8. ABDOMINAL PAIN (VERY RARE) can precede onset of hepatitis. 9. RASH (VERY RARE) within the framework of a hepatic attack. Can precede jaundice by 24 to 48 hours. 10. TOXIC HEPATITIS (VERY RARE) Generally moderate and transitory increase in the hepatic enzymes. Several cases of hepatitis were reported. Their evolution was always favorable to the discontinuation of the drug: - Press Med 1980; 9:3689-3692. - Sem Hop Paris 1981; 57:1992-1996. Two additional cases: - Hepatogastroenterology 1996; 43-1015-1019. 11. ELEVATED TRANSAMINASES (RARE) Generally moderated, isolated and transitory increase. 12. ELEVATED ALKALINE PHOSPHATASE (RARE ) 13. ELEVATED BILIRUBIN (RARE ) 14. JAUNDICE (VERY RARE) Preceded by a pre-jaundice phase (abdominal pains, nausea, fever and rash), in which case the drug must be discontinued immediately. 15. MIXED HEPATITIS (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). - Contest Med 1982; 104:5733-5734.
