Prolastin-C Liquid
Prolastin-C Liquid, commonly known as simply Prolastin, is an alpha-1 proteinase inhibitor. It's used as augmentation therapy to manage lung problems (emphysema) in adults with a genetic condition called alpha-1 antitrypsin (AAT) deficiency. This medication helps replace an enzyme that's missing in the body called AAT. Prolastin is given as an infusion into the veins (IV) once a week. Side effects aren't common, but can include headache and common cold symptoms.
What is Prolastin?
What is Prolastin used for?
- Augmentation therapy for lung damage (emphysema) due to severe alpha-1 antitrypsin (AAT) deficiency
How Prolastin works
Alpha-1 antitrypsin (AAT), or alpha-1 proteinase inhibitor, is an enzyme (protein) that your body normally makes to help protect the lungs from damage. Without enough AAT, there's a higher risk for lung problems, like emphysema.
Prolastin is an enzyme replacement therapy. It restores the levels of AAT in adults with (AAT deficiency) to help protect the lungs.

Pharmacist tips for Prolastin
- Mark your calendar with your appointments to see your provider and when your Prolastin once-weekly infusions are due. This will help you and your provider keep track of your treatment and make sure you don't miss any doses.
- Allergic reactions or infusion-related reactions can happen during or after your Prolastin infusion. Get medical help right away if you have any signs of an allergic reaction or anaphylaxis, including trouble breathing or rash, so you can get treated as soon as possible.
Getting Prolastin infusions at home (if instructed by your provider):
- Depending on your insurance coverage and discussions with your provider, you might be able to get your Prolastin infusions at home. Your care team can arrange for a trained nurse to make a home visit to help administer the medication.
- You'll get the Prolastin vials delivered directly to your home before your appointments with the nurse for your infusions.
- Store Prolastin vials in the refrigerator and in the original container to protect them from light. You can also store them at room temperature for up to 1 month. But once the medication is at room temperature, don't put it back in the refrigerator and don't use it if it's been at room temperature for longer than 1 month.
- When the nurse arrives for the appointment for your Prolastin infusion, they'll help prepare your dose. The nurse might need to transfer the liquid from multiple vials into an empty, sterile bag that's then used for the infusion.
- Once your dose is prepared, it must be given within 3 hours. The medication doesn't contain any preservatives, so bacteria might start to grow in the solution if it hasn't been used for some time. Your nurse will need to prepare a new dose for your infusion.
- After each Prolastin infusion, the home nurse will help you keep track of your infusions. The nurse will probably use a treatment log to write down the lot number of the vial(s) used, the time and date of your infusions, and any side effects or reactions that you have.
Common questions about Prolastin
You'll probably get your first few Prolastin infusions at a clinic or infusion center so you can be closely monitored for side effects and allergic reactions to the medication. Plan for some time at the beginning of your appointment to check in and fill out some paperwork. Your care team might check your vitals and ask some questions to see how you're generally doing. The actual Prolastin infusion only takes about 15 minutes, as long as you're tolerating the infusion okay. It's also safe to drive yourself to and from the appointment because the medication doesn't typically cause sleepiness or dizziness. Call the place where you'll get Prolastin infusions if you have specific questions about what to expect.
It's possible to get your Prolastin infusions at home, depending on your insurance coverage and if your provider feels it's safe for you to do so. Your care team might arrange for a trained healthcare provider to make a home visit to administer Prolastin. In this case, you'll get the medication delivered directly to your home before your appointments with the home nurse. Discuss with your providers to see whether getting Prolastin infusions at home is right for you.
If you're feeling sick during the Prolastin infusion, let a healthcare provider know right away. The provider might slow down your infusion or stop the infusion until you feel better. They also might recommend other medications to help relieve your symptoms, for example acetaminophen (Tylenol) for fever. If you feel generally sick and aren't well enough to get your infusion, call your provider to see what to do and whether to reschedule your appointment.
Both Prolastin-C Liquid (or sometimes simply known as Prolastin) and Zemaira are brand-name medications that contain the same active ingredient, alpha 1-proteinase inhibitor. These two brands are very similar to each other. Studies show that brands of alpha 1-proteinase inhibitors are safe and work just as well as each other. Prolastin-C Liquid and Zemaira are given as once-weekly infusions through the vein with the help of a trained healthcare provider. The main difference between them is that Prolastin-C Liquid is available as a liquid that's ready for infusion, whereas Zemaira comes as a powder that needs to be mixed before administration. Discuss with your provider about which brand is right for you.

Risks and warnings for Prolastin
Prolastin can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Severe allergic reactions
- Risk factors: Immunoglobulin A (IgA) deficiency
Prolastin might contain a tiny amount of immunoglobulin A (IgA), which is a type of protein that's naturally found in the body. People who have IgA deficiency can have antibodies against IgA. Having antibodies against IgA raises the risk of having an allergic reaction, including anaphylaxis, to Prolastin.
Let your provider know right away or contact emergency medical help if you have any signs of a severe allergic reaction, such as hives, itching, swelling in the mouth or throat, chest tightness, trouble breathing, wheezing, or feeling faint or lightheaded. Your provider might prescribe an epinephrine pen (EpiPen) for you to use in case of a severe allergic reaction.
Risk of infection
Because Prolastin is made from human blood products, there's a risk that it might contain viruses and other germs that can make you sick. But your risk of infection is low since the donors of these blood products are carefully screened. Also, there are high manufacturing standards put into place to make sure the germs are killed or removed.
To prevent serious infections in the rare case that your doses of Prolastin are affected, let your provider know right away if you start to feel sick or have symptoms, such as feeling confused and anxious or having trouble maintaining your balance.
Prolastin dosage
Typical dosage for Prolastin
The typical dose is 60 mg/kg of body weight, given as an infusion into the vein (intravenous or IV) once a week.
Interactions between Prolastin and other drugs
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Prolastin contraindications
Contraindications are specific health conditions or situations in which a person should not take a medication due to safety concerns. If you have any of the following conditions or if any of the following apply to you, let your healthcare provider know because Prolastin will not be safe for you to take.
- People who are immunoglobulin A (IgA) deficient with antibodies against IgA
- Severe allergy to other alpha 1-proteinase inhibitors
