Aminoleban (parenteral)

Uses|Precautions & Warnings|Side Effects|Interactions|Dosage


What is Aminoleban used for?

Aminoleban is a preparation of essential and non-essential amino acids. Amino acids are considered “incomplete proteins” or the building blocks of proteins, owing to their nitrogen content, and are necessary for the synthesis of biologically important substances like neurotransmitters, hormones, and muscle fibers.

Essential amino acids are the amino acids that cannot be synthesized by the human body and must be obtained through eating food such as meat and other sources of protein. Non-essential amino acids are normally obtained through a series of intracellular metabolic processes.

Aminoleban is mainly indicated to treat the following conditions:

  • Hepatic encephalopathy
  • Chronic liver disease

How should I take Aminoleban?

Aminoleban is available as a parenteral solution for infusion. It is injected through the intravenous (IV) route and should not be taken as an oral solution. The dose must be administered slowly via IV infusion to minimize injection site irritation and adverse effects. It should be administered by a licensed health professional.

How do I store Aminoleban?

This drug should be stored at room temperature (<30°C) and be protected from light and moisture. Do not allow this product to freeze. Crystallization may occur at low temperatures and should be warmed at 50-60°C to dissolve the crystals. Administer the solution when the temperature reaches normal body temperature (~37°C).

Always check the label before using this product. Do not use if the printed expiration date has passed, the product seal has been broken, or the product has changed in color, odor, or consistency. For safety, keep out of the reach of children and pets.

Do not dispose of this product by pouring it down the drain, toilet, or into the environment. Ask your pharmacist regarding the proper way and location of disposal.

Precautions & Warnings

What should I know before using Aminoleban?

Each amino acid preparation is uniquely blended and designed to treat metabolic disorders, supplement nutritional requirements, or correct deficiencies. Aminoleban may not be a suitable substitute for other amino acid solutions to treat a specific condition.

Aminoleban contains sodium and chloride in addition to amino acids so careful monitoring of electrolyte balance is necessary when given with an electrolyte solution or in large doses.

Before using this medication, inform your doctor if:

  • You have ever had an adverse reaction to Aminoleban or other amino acid preparations
  • You have a history of allergy to other medications, food, or other substances
  • You are taking other medications, especially other sources of nitrogen or electrolytes
  • You have underlying health conditions, such as renal disfunction

Is it safe during pregnancy or breastfeeding?

During pregnancy, protein and amino acid requirements are increased to support both maternal health and fetal growth. Generally amino acid administration is safe, even necessary in certain cases. However, the types and doses of amino acids should be individualized. This preparation should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus, as determined by your doctor.

This drug may be excreted in breast milk. This drug should be used while breastfeeding only if the potential benefit justifies the potential risk to the child, as determined by your doctor.
