USES
Aralast NP is administered as an intravenous (IV) infusion. A healthcare professional will prepare the medication to ensure it is mixed and diluted appropriately before injection.
Preparation: The Aralast NP vial is reconstituted with sterile water, and the solution is then prepared for infusion.
Administration: Aralast NP is typically administered once a week. The patient will receive the infusion in a clinical setting or at home if the healthcare provider approves home infusion.
Monitoring: The patient will be monitored for immediate allergic reactions and side effects during infusion. Infusions are relatively tolerated; however, in some cases, patients do report symptoms of fever and chills.
Patients should adhere to the prescribed regimen and regularly come for follow-up to ensure that the drug is not causing any adverse reactions. The infusion schedule or the dose can be altered depending on the patient’s response and any side effects he or she may experience.
WORKING
Aralast NP works by replacing the deficient alpha-1 antitrypsin protein in AATD patients. This protein produced by the liver is transported into the blood stream wherein it exerts its action. In the healthy organism, alpha-1 antitrypsin prevents the action of enzymes, for instance, neutrophil elastase, from causing any damage to lung tissue.
In individuals with AATD, neutrophil elastase does not have sufficient alpha-1 antitrypsin to inhibit it properly. This results in an unchecked neutrophil elastase that destroys lung tissue and leads to emphysema or other types of lung diseases. Since this drug delivers a purified version of this protein, Aralast NP prevents further deterioration of the lungs, slow the progression of emphysema, and hence decrease the use of supplementary treatment, such as bronchodilators or inhaled steroids.
The protein provided by Aralast NP also reduces inflammation and can have a protective effect on the liver, which is particularly important for individuals who are at risk of liver disease due to AATD.
SIDE EFFECTS
Common side effects of Aralast NP may include:
Infusion-related reactions: These involve fever, chills, rash, and nausea, which usually resolve after infusions are completed. Such patients may need medical evaluation if the reaction is particularly severe.
Allergic reaction: This is a rather rare occurrence but can develop as hives, shortness of breath, or swelling for some patients. Such symptoms should be evaluated immediately to avoid further complications.
Other side effects: Some patients may suffer from joint pains, fatigue, or even mild respiratory symptoms. The side effects are usually mild and temporary.
Serious side effects are rare and include:
Anaphylactic reaction: This is a severe allergic reaction that requires immediate medical attention.
Hepatic complications: Although this is rare, some patients may suffer from liver problems due to the infusion therapy.
WARNINGS
Allergic Reactions: Patients have to be kept under a close watch for any symptoms of allergic reaction to the Aralast NP through and after infusion. Special care may have to be taken for the patient that has had some history of severe allergic reaction to an intravenous therapy.
Infusion Reactions: Health care should keep the patient under regular observation while infusion is made. Some infusion reactions experienced are fever, chills, or even hives, though it is minimal.
Liver Disease: Patients with existing liver conditions should be closely monitored, as alpha-1 antitrypsin deficiency itself can cause liver damage, and Aralast NP may exacerbate this in some individuals.
Pregnancy and Breastfeeding: The safety of Aralast NP during pregnancy and breastfeeding has not been fully established. It is important for pregnant or breastfeeding women to discuss the risks and benefits with their healthcare provider before starting treatment.
INTERACTIONS
Since Aralast NP is a replacement therapy for a protein in the body, it is unlikely to interact with most drugs. However, as with any infusion therapy, patients receiving Aralast NP should be monitored for potential allergic reactions or infusion-related side effects.
There are no known major drug-drug interactions with Aralast NP; however, all medications the patient is taking should be brought to the attention of the healthcare provider, including over-the-counter drugs and supplements.
DOSAGE
The standard dose of Aralast NP is based on the patient’s weight. The average dose is 60 mg/kg body weight, and it is administered once a week via intravenous infusion. The healthcare provider can adjust the dosing regimen based on the clinical response of the patient and side effects experienced. Follow-up visits are necessary to monitor the condition of the patient and see if changes are required.
PRESCRIPTION
Aralast NP can only be prescribed, thus a healthcare provider should possess experience in the treatment and management of alpha-1 antitrypsin deficiency. A health professional will assess the clinical status of the patient to know the appropriate dosing regimen. Patients on Aralast NP will also require constant assessment and follow-up appointments so that the effectiveness of their treatment and any possible adverse effects can be reviewed.
