DrugBank ID	DB00129
Name	Ornithine
Groups	nutraceutical approved
Description	Produced during the urea cycle, ornithine is an amino acid produced from the splitting off of urea from arginine. L-Ornithine allows for the disposal of excess nitrogen and acts as a precursor of citrulline and arginine.
Synonyms	(S)-2,5-diaminovaleric acid Ornithine Ornithine hydrochloride Ornithine aspartate Ornitina Ornithine oxoglurate Ornithine dihydrochloride (S)-α,δ-diaminovaleric acid (S)-ornithine (S)-2,5-Diaminopentanoic acid levo-ornithine (S)-2,5-Diaminopentanoate Ornithinum L-Ornithine
Brand Names	Primene 10% Primene 10%-liq IV Primene
Indication	Used for nutritional supplementation, also for treating dietary shortage or imbalance. It has been claimed that ornithine improves athletic performance, has anabolic effects, has wound-healing effects, and is immuno-enhancing.
