Question 1

What is berotralstat?

Accepted Answer

Berotralstat is a medication classified as a plasma kallikrein inhibitor. It functions by blocking the activity of plasma kallikrein, an enzyme that triggers the release of bradykinin in the blood.

By controlling the levels of bradykinin, the medication helps manage the underlying biological processes that lead to excessive swelling. This mechanism is intended to provide a preventive approach to managing hereditary angioedema attacks.

Question 2

What is berotralstat used for?

Accepted Answer

berotralstat is used to treat hereditary angioedema .

Question 3

How does berotralstat work?

Accepted Answer

Mechanism of Action

Berotralstat belongs to a class of medications called plasma kallikrein inhibitors. It is used for the routine prevention of attacks of hereditary angioedema (HAE), a genetic condition that causes episodes of severe swelling in various parts of the body.

How it Prevents Swelling

In people with HAE, a substance in the blood called bradykinin is produced in excessive amounts. Bradykinin causes blood vessels to widen and leak fluid into surrounding tissues, which results in the characteristic swelling and pain of an HAE attack.

Berotralstat works by targeting the biological pathway that creates bradykinin:

Inhibiting Plasma Kallikrein: The medication binds to plasma kallikrein, which is an enzyme (a type of protein) responsible for releasing bradykinin.

Lowering Bradykinin Levels: By blocking the activity of plasma kallikrein, berotralstat reduces the overall production of bradykinin in the body.

Preventing Inflammation: With less bradykinin circulating, blood vessels are less likely to leak, which helps prevent the onset of swelling episodes.

Because berotralstat works by maintaining a steady level of enzyme inhibition, it is taken daily to provide ongoing protection. It is important to note that this medication is a preventive treatment and is not intended to treat an acute HAE attack once it has already started.

Question 8

What is the dosage of berotralstat and how do I take it?

Accepted Answer

How to Take Berotralstat

Berotralstat is a capsule taken by mouth, usually once daily. It should be taken with food to ensure proper absorption. Try to take your dose at the same time each day to maintain a consistent level of medicine in your body.

Missed Doses

If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your regular schedule. Do not take more than one dose in a single day.

Administration Tips

Swallow the capsule whole. Do not break, chew, or open the capsule.

This medication is used for the prevention of hereditary angioedema attacks and should not be used to treat an acute attack once it has started.

Keep the medication in its original container at room temperature, protected from moisture and light.

Question 9

Is berotralstat safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There are no adequate and well-controlled studies of berotralstat in pregnant women. While animal studies did not show evidence of harm to the fetus at doses significantly higher than the recommended human dose, human data are currently insufficient to determine if there is a drug-associated risk of birth defects or miscarriage.

Breastfeeding

It is not known whether berotralstat is present in human breast milk, how it affects milk production, or if it has any effect on a breastfed infant. Animal studies have shown that the drug is present in the milk of lactating rats. Because of the potential for adverse reactions in a nursing infant, the benefits of breastfeeding should be weighed against the mother's clinical need for the medication.

If you are pregnant, planning to become pregnant, or breastfeeding, you should discuss the potential risks and benefits of berotralstat with your healthcare provider to determine the best course of treatment.

Question 10

What forms and strengths does berotralstat come in?

Accepted Answer

FDA Approval Status

The U.S. Food and Drug Administration (FDA) approved berotralstat in December 2020. It was the first oral, non-steroidal treatment option approved specifically for the prevention of hereditary angioedema (HAE) attacks.

Approved Indications

Berotralstat is indicated for routine prophylaxis to prevent attacks of hereditary angioedema in adults and pediatric patients aged 12 years and older. It is designed for long-term, daily use to reduce the frequency of swelling episodes.

Limitations of Use

The FDA-approved labeling includes specific limitations regarding the use of this medication:

It should not be used to treat an acute HAE attack. Patients must have access to separate rescue medications for the immediate treatment of breakthrough symptoms.

The safety and effectiveness of berotralstat for the treatment of acute attacks have not been established.

Safety and Monitoring

There are currently no boxed warnings or Risk Evaluation and Mitigation Strategies (REMS) programs required by the FDA for berotralstat. As with all approved medications, it is subject to ongoing safety monitoring through the FDA MedWatch program to track adverse events and ensure continued safety for the public.

Question 12

What should I know about berotralstat and cost?

Accepted Answer

Insurance and Prior Authorization

Most insurance providers require a process called prior authorization before they will cover the cost of berotralstat. Your healthcare provider will need to submit specific medical information to your insurance company to justify the use of this medication for hereditary angioedema prophylaxis.

Specialty Pharmacy Requirements

Berotralstat is typically dispensed through specialty pharmacies. These pharmacies specialize in high-cost medications that require unique handling or monitoring. The cost may be influenced by the specific specialty pharmacy your insurance plan requires you to use.

Patient Support and Savings

Financial assistance may be available to help manage the out-of-pocket costs of berotralstat.
