L-alanyl-L-tyrosine is a parenteral nutrition drug. The following are the precautions for its use:
I. Related to the Applicable Population
People in Special Physiological States
Pregnant Women and Lactating Women: Currently, there is limited research data on the safety and effectiveness of L-alanyl-L-tyrosine when used in pregnant women and lactating women. Therefore, it can only be used under the strict guidance of a doctor when there is a clear need and the benefits outweigh the risks.
Children: The dosage and safety of L-alanyl-L-tyrosine used in children may be different from those in adults. Doctors need to accurately calculate the dosage according to factors such as the child's age, weight, and condition, and closely monitor the reactions during the use process.
The Elderly: The organ functions of the elderly may decline, and their tolerance and responsiveness to the drug may be different from those of young people. When using this drug, it is necessary to pay attention to indicators such as liver and kidney functions, and adjust the dosage if necessary.
Patients with Specific Diseases
Patients with Amino Acid Metabolism Disorders: L-alanyl-L-tyrosine is an amino acid drug. Using it in patients with amino acid metabolism disorders may exacerbate the metabolic abnormalities, so such patients are prohibited from using it.
Patients with Severe Hepatic and Renal Insufficiency: The liver and kidneys are important organs for drug metabolism and excretion. Patients with severe hepatic and renal insufficiency may not be able to metabolize and excrete the drug normally, leading to the accumulation of the drug in the body and increasing the risk of adverse reactions. Generally, it is not recommended for them to use this drug.
II. During the Drug Use Process
Usage and Dosage
It is necessary to strictly follow the usage and dosage specified in the doctor's prescription and the drug instruction manual. Usually, it is administered as part of the parenteral nutrition solution by intravenous infusion. The infusion rate should not be too fast to avoid adverse reactions such as nausea, vomiting, and facial flushing.
When mixing it with other drugs, pay attention to the drug compatibility 禁忌. Avoid drug interactions that may reduce the drug efficacy or cause adverse reactions. For example, it cannot be mixed with alkaline solutions or solutions containing phosphates or carbonates because precipitation may occur.
Medication Monitoring
During the use process, it is necessary to closely monitor the patient's relevant indicators, such as liver and kidney functions, electrolyte levels, blood glucose, and blood routine, etc., in order to promptly detect possible adverse reactions and metabolic abnormalities, and adjust the treatment plan according to the monitoring results.
Observe the patient's clinical symptoms, such as whether there are allergic reactions like fever, rash, and difficulty breathing, as well as symptoms of gastrointestinal discomfort. Once any abnormalities occur, inform the doctor immediately and take corresponding treatment measures.
III. Storage and Shelf Life
Storage Conditions: L-alanyl-L-tyrosine usually needs to be stored in a cool and dry place. The specific storage temperature requirements should refer to the drug instruction manual. Generally speaking, avoid high temperatures, humidity, and light to ensure the stability and effectiveness of the drug.
Shelf Life: Carefully check the shelf life of the drug before use. It is strictly prohibited to use expired drugs. At the same time, pay attention to the usage period after the drug is opened. If it has been opened but not used up, it should be properly stored according to the requirements of the instruction manual and used up within the specified time.
