# Hepamerz (L-Ornithine L-Aspartate) ## Overview Hepamerz is a combination of two amino acids, L-ornithine and L-aspartate. It is believed to reduce ammonia levels in the blood by promoting its detoxification in the liver and kidneys. ## Primary Indications * Treatment of hyperammonemia associated with liver insufficiency, particularly in the context of hepatic encephalopathy. ## Adult Dosing * **Oral:** Typically 3 g (which is equivalent to 9 g of Hepamerz, as Hepamerz contains 1g L-Ornithine L-Aspartate per 3g) three times daily. Doses can range from 3g to 18g per day, divided into doses. * **Intravenous:** Typically 5 g to 10 g (of L-Ornithine L-Aspartate) per day, administered as a continuous infusion over 24 hours or divided into 2-3 infusions. The total daily dose should not exceed 10g. *Note: The "%25252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520%25252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252528l-Ornithine%25252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520l-Aspartate%25252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520-%25252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520lola%25252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252529 indicates the specific commercial product name of Hepamerz, which contains 1 gram of L-Ornithine L-Aspartate per 3 grams of product.
