Olimel N9 (Valine, Alanine, Arginine, Histidine, Isoleucine, Leucine, Methionine, Phenylalanine, Proline, Serin)

Olimel N9 provides a comprehensive amino acid profile for patients who need intravenous nutritional support. It is used in the following clinical situations:

• Post‑operative recovery: Helps to restore nitrogen balance and support tissue repair.
• Critical illness or severe trauma: Supplies essential amino acids when oral intake is insufficient.
• Long‑term parenteral nutrition: Maintains protein synthesis and prevents muscle wasting.

• The formulation delivers a balanced mixture of essential and non‑essential amino acids directly into the bloodstream, bypassing gastrointestinal absorption. These amino acids serve as substrates for protein synthesis, support nitrogen balance, and act as precursors for neurotransmitters and metabolic intermediates, thereby facilitating tissue repair and metabolic stability.

Adverse reactions reported with intravenous amino‑acid mixtures are generally related to the infusion process and individual sensitivity.

Common Side Effects

• Mild fever or chills during infusion.
• Transient erythema or irritation at the IV site.
• Nausea or mild gastrointestinal discomfort.
• Headache.
• Elevated serum potassium levels.
• Slight increase in blood urea nitrogen.

Serious or Rare Side Effects

• Anaphylactic or severe hypersensitivity reaction.
• Acute metabolic acidosis.
• Hyperammonemia.
• Thrombophlebitis at the infusion site.
• Severe electrolyte disturbances.
• Renal impairment in susceptible patients.

When using Olimel N9, clinicians should consider the following precautions:

• Assess renal function: Adjust dosing in patients with impaired kidney function.
• Monitor electrolytes: Regularly check serum electrolytes and acid‑base status.
• Evaluate nitrogen balance: Ensure appropriate protein intake to avoid overload.
• Observe infusion site: Watch for signs of phlebitis or infiltration.
• Review concomitant nutrition: Coordinate with total parenteral nutrition regimens to prevent excess amino acids.
• Store at ambient temperature: Keep in original packaging, protect from moisture and direct light.

Intravenous amino‑acid solutions may interact with other medications administered concurrently.

Major Interactions (Avoid)

• High‑dose potassium supplements: May exacerbate hyperkalemia.
• Acidifying agents (e.g., ammonium chloride): Increase risk of metabolic acidosis.
• Certain antibiotics antibiotics: May precipitate when mixed in the same bag.

Moderate Interactions (Monitor Closely)

• Loop diuretics: Can alter electrolyte balance.
• Insulin therapy: May enhance intracellular potassium shift.
• Anticoagulants: May require dose adjustment due to changes in plasma protein binding.
