Contra Indications
Known hypersensitivity to ademetionine
Precautions
Ammonia levels should be monitored in patients with precirrhotic and cirrhotic states of hyperammonemia taking oral ademetionine.
Because vitamin B12 and folate deficiencies may decrease ademetionine levels, at risk patients (anemia, liver disease, pregnancy or potential for vitamin deficiencies due to other illnesses or eating habits eg, vegans) should have routine blood tests to check the plasma levels. If a deficiency is found, treatment with vitamin B12 and/or folate is recommended prior to or concurrently with administration of ademetionine.
Pregnancy-Lactation
Interactions
Serotonin syndrome has been reported in patients taking ademetionine and clomipramine. Therefore, although a potential interaction is postulated, caution is recommended when administering ademetionine concomitantly with SSRIs, tricyclic antidepressants (eg, clomipramine), and over-the-counter and herbal supplements-containing tryptophan

Mechanism of Action
S-adenosyl-L-methionine (ademetionine) is a naturally occurring amino acid present in virtually all body tissues and fluids. Ademetionine functions primarily as a coenzyme and donor transfer of the methyl group (transmethylation) is an essential metabolic process in humans and animals. Methyl transfer is also essential to the development of the phospholipid bilayer of cell membranes and contributes to membrane fluidity.
Ademetionine can penetrate the blood-brain barrier and ademetionine-mediated transmethylation is critical in the formation of neurotransmitters in the central nervous system including catecholamines (dopamine, noradrenalin, adrenaline), serotonin, melatonin and histamine.
Ademetionine is also a precursor in the formation of physiological sulfurated compounds (cysteine, taurine, glutathione, CoA, etc) via transsulfuration. Glutathione, the most potent antioxidant in the liver, is important in hepatic detoxificatlon. Ademetionine increases hepatic glutathione levels in alcoholic and non-alcoholic liver disease patients. Both folate and vitamin B12 are essential co-nutrients in the metabolism and replenishment of ademetionine.
