Question 1

What is Orladeyo?

Accepted Answer

Orladeyo is a plasma kallikrein inhibitor that works by decreasing the activity of an enzyme responsible for fluid leakage and inflammation in the body. By regulating this pathway, the medication helps control the biological processes that lead to sudden and severe swelling.

This therapy is designed to provide ongoing management of the proteins that trigger inflammatory responses. It functions by limiting the production of certain substances in the blood that cause blood vessels to dilate and leak fluid into surrounding tissues.

Question 2

What is Orladeyo used for?

Accepted Answer

Orladeyo is used to treat routine prevention of hereditary angioedema attacks.

Question 3

How does Orladeyo work?

Accepted Answer

Mechanism of Action

Orladeyo belongs to a class of medications known as plasma kallikrein inhibitors. It is designed to prevent attacks of hereditary angioedema (HAE) by targeting the underlying cause of swelling in the body.

In people with HAE, an enzyme called plasma kallikrein becomes overactive. This overactivity leads to the excessive release of a substance called bradykinin. Bradykinin is a natural peptide that causes blood vessels to widen and leak fluid into nearby tissues, which results in localized swelling, pain, and inflammation.

Orladeyo works by:

Binding to the plasma kallikrein enzyme.

Reducing the enzyme's ability to produce bradykinin.

Lowering the overall levels of bradykinin in the body.

By keeping bradykinin levels under control, the medication helps prevent the blood vessels from leaking, thereby reducing the frequency of HAE attacks. It is important to note that Orladeyo is a preventive treatment and is not intended to treat an acute HAE attack once it has already started.

Question 7

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

Accepted Answer

How to Take This Medication

Orladeyo is typically taken once a day. It should be swallowed whole with food. Do not crush, chew, or open the capsules. It is helpful to take the medication at the same time each day to maintain a consistent level in your body.

Missed Dose

If you miss a dose of Orladeyo, skip the missed dose and take your next dose at the regular scheduled time. Do not take two doses at once or take more than one dose in a single day to make up for a missed one.

Storage and Handling

Store the capsules at room temperature in a dry place. Keep the medication in its original container and out of reach of children.

Question 8

Is Orladeyo safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Data regarding the use of Orladeyo in pregnant individuals are insufficient to determine if there is a drug-associated risk for major birth defects, miscarriage, or other adverse outcomes. In animal reproduction studies, no evidence of harm to the fetus was observed when berotralstat was administered at doses significantly higher than the recommended human dose.

If you are pregnant or planning to become pregnant, talk to your doctor about the potential benefits and risks of using this medication during pregnancy.

Breastfeeding

It is not known whether Orladeyo passes into human breast milk, how it affects a nursing infant, or if it impacts milk production. Research in animals has shown that berotralstat is present in the milk of lactating rats. Because many drugs are excreted in human milk, caution is advised.

Consult your healthcare provider to discuss the best way to feed your baby while taking Orladeyo and to weigh the benefits of breastfeeding against the potential risks to the infant.

Question 9

What forms and strengths does Orladeyo come in?

Accepted Answer

Orladeyo is supplied as a capsule for oral administration. It is intended to be taken by mouth, typically once daily with food.
