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.
กลไกการออกฤทธิ์: 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.
