Amino acid solutions
Amino acid solutions are used parenterally to supply essential and non-essential amino acids for protein production in patients requiring nutritional support but unable to receive enteral support. They have also been used in the treatment of superficial necrolytic dermatitis in dogs. > **Clinical Warning:** The authorized veterinary preparation (Duphalyte) contains insufficient amino acids to meet basal requirements for protein production and is intended only as an aid for IV fluid support. > **Species Specific Warning:** None of the human formulations contain **taurine**, which is essential for cats and for specific conditions in dogs. All products are hyperosmolar.
Mechanism: Provides synthetic crystalline **L-amino acids** which act as building blocks for protein synthesis. → Supports protein anabolism → Arrests protein and muscle wasting → Maintains intermediary metabolism.
Routes of administration
Contraindications
- Dehydration
- Hepatic encephalopathy
- Severe azotaemia
- Shock
- Congestive heart failure
- Electrolyte imbalances
Adverse effects
- Hyperglycaemia
- Hyperlipidaemia
- Hypercapnia
- Acid-base disturbances
- Electrolyte disturbances (e.g., hypophosphataemia / refeeding syndrome)
- Catheter-associated thrombophlebitis
- Bacterial colonization of the catheter
- Bacteraemia and septicaemia
- Severe tissue damage (if extravasated)
Monitoring
- Blood glucose
- Serum electrolytes (potassium, phosphorus, magnesium, sodium)
- Acid-base status
- Serum triglycerides/lipids
- Renal and hepatic parameters
- Catheter site for signs of thrombophlebitis or infection
- Body weight and hydration status
Overdose
Excessive administration rates can lead to severe metabolic complications, including hyperglycaemia, hyperlipidaemia, hypercapnia, and life-threatening electrolyte imbalances (such as hypophosphataemia associated with refeeding syndrome). Overdose of potassium-containing solutions may cause fatal hyperkalaemia.
