Oleunor Perifer N4e (Valine, Alanine, Arginine, Histidine, Isoleucine, Leucine, Methionine, Phenylalanine, Proline, Serin)

Oleunor Perifer N4e is used in clinical situations that involve protein‑energy malnutrition and catabolic stress where amino acid provision is critical.

• Parenteral nutrition: supports formulation of complete nutrition solutions for patients unable to eat orally.
• Amino acid deficiency: corrects deficits of essential amino acids in patients with impaired absorption or increased loss.
• Catabolic states: helps maintain lean body mass during severe illness, trauma or post‑operative recovery.
• Critical care: provides necessary substrates for metabolic processes in intensive‑care patients.
• Surgical recovery: aids in tissue repair and wound healing after major operations.

• Oleunor Perifer N4e supplies a balanced mixture of essential and non‑essential amino acids that are directly incorporated into cellular protein synthesis pathways. The amino acids act as substrates for the mTOR signaling cascade, stimulate ribosomal activity, and support gluconeogenesis and nitrogen balance, thereby facilitating tissue repair and metabolic homeostasis during intravenous nutrition.

Adverse reactions are generally related to the intravenous route and the amino acid composition.

Common Side Effects

• Mild infusion‑related erythema or flushing.
• Transient nausea or vomiting.
• Slight elevation of serum ammonia levels.
• Minor electrolyte disturbances (e.g., potassium shift).
• Localized vein irritation at the infusion site.

Serious or Rare Side Effects

• Severe hypersensitivity or anaphylaxis.
• Acute metabolic acidosis.
• Hyperosmolar shock due to rapid infusion.
• Significant hyperkalemia or hypocalcemia.
• Renal impairment exacerbated by amino acid load.
• Thromboembolic events linked to catheter use.

When using Oleunor Perifer N4e, clinicians should observe standard safety measures for intravenous nutrition.

• Assess baseline renal and hepatic function: adjust dosage if impairment is present.
• Monitor serum electrolytes and ammonia: correct abnormalities promptly.
• Observe for signs of hypersensitivity: be prepared to discontinue infusion.
• Use aseptic technique during preparation and administration.
• Avoid rapid bolus administration: infuse at recommended rate.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Oleunor Perifer N4e may interact with other intravenously administered agents that affect electrolyte or nitrogen balance.

Major Interactions (Avoid)

• Concurrent high‑dose potassium chloride: risk of severe hyperkalemia.
• Acidifying solutions (e.g., sodium bisulfite): may precipitate amino acids.

Moderate Interactions (Monitor Closely)

• Loop diuretics: can amplify electrolyte shifts.
• Renal replacement therapies: may alter amino acid clearance.
• Other parenteral nutrition modules: require compatibility testing.
• Certain antibiotics antibiotics: may affect infusion pH and stability.
• Vasopressors: may influence peripheral circulation at the infusion site.
