Question 1

What is Inbrija?

Accepted Answer

This medication is a formulation of levodopa that serves as a dopamine precursor to assist with motor control. It is designed to supplement existing maintenance therapies by providing an additional source of medication that the brain converts into dopamine to help manage fluctuations in movement symptoms.

This therapy helps address periods when standard maintenance treatments are not providing sufficient relief. By increasing available dopamine, it supports more consistent control over physical activity and coordination.

Question 2

What is Inbrija used for?

Accepted Answer

Inbrija is used to treat Parkinson's disease off episodes.

Question 3

How does Inbrija work?

Accepted Answer

How Inbrija Works

Inbrija is an inhaled form of levodopa, which belongs to a class of drugs known as dopamine precursors. It is used to treat "off" episodes in people with Parkinson's disease who are already taking carbidopa/levodopa oral medications.

Parkinson's disease occurs when the brain does not produce enough dopamine, a chemical messenger responsible for controlling body movements. When dopamine levels are low, it can lead to tremors, stiffness, and difficulty moving.

The medication works in the following ways:

Rapid Absorption: Because the medication is inhaled, it enters the bloodstream through the lungs. This allows it to bypass the digestive tract, which can be helpful during "off" periods when oral medications may take longer to work or are less effective.

Dopamine Replacement: Once levodopa enters the brain, it is converted into dopamine. This helps to replenish the brain's supply of the chemical.

Restoring Movement: By increasing dopamine levels, the drug helps the brain send signals to the muscles more effectively, reducing the physical symptoms that return during an "off" period.

Question 7

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

Accepted Answer

How to Use Inbrija

Inbrija is for oral inhalation only. The medication comes in capsules that are placed into a specific inhaler device. Do not swallow the capsules. To use the medication, insert the capsules into the inhaler, pierce them using the device, and inhale the powder through your mouth.

When using the inhaler, breathe out fully before placing the mouthpiece in your mouth. Take a deep, steady breath to pull the powder into your lungs, then hold your breath for a few seconds before exhaling slowly. You may need to repeat the inhalation process for each capsule in a dose as directed by your healthcare provider.

General Dosing Information

This medication is used as needed when you begin to feel Parkinson's symptoms returning. It is not intended to replace your regular carbidopa/levodopa maintenance therapy. There is a limit to how many times you should use this medication within a day; follow the specific instructions provided by your doctor.

Missed Dose

Because Inbrija is used only when needed for "off" episodes, you do not have a regular dosing schedule. If you miss a dose during an "off" period, you may take it when you remember, provided you do not exceed the maximum daily limit. Do not use extra medication to make up for a missed dose.

Question 8

Is Inbrija safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There is limited data on the use of Inbrija in pregnant women. It is currently unknown if the medication can cause harm to a developing fetus. In animal studies, high doses of levodopa were linked to developmental concerns, though these results do not always translate to human outcomes.

If you are pregnant or planning to become pregnant, discuss your treatment options with your doctor to determine if the benefits of using Inbrija outweigh the potential risks.

Breastfeeding

It is not known whether Inbrija passes into breast milk or how it might affect a nursing infant. Additionally, levodopa may potentially decrease the production of breast milk. Healthcare providers typically recommend caution when considering breastfeeding while using this medication.

Question 9

What forms and strengths does Inbrija come in?

Accepted Answer

Inbrija is available as a dry powder for oral inhalation. The medication is contained within capsules that are designed to be used exclusively with a specific plastic inhaler device provided with the prescription.

Administration Method

Inhalation Powder: The powder is released from the capsule when used with the inhaler.

Capsule Use: The capsules are for oral inhalation only and must not be swallowed.

Question 10

What is the FDA approval status of Inbrija?

Accepted Answer

FDA Approval and Indication

Inbrija was approved by the U.S. Food and Drug Administration (FDA) in December 2018. It is specifically indicated for the intermittent treatment of "off" episodes in people with Parkinson's disease. These episodes occur when a patient's regular maintenance medication (carbidopa/levodopa) wears off and symptoms such as tremors or difficulty moving return.

Regulatory Requirements

Inbrija is not intended to replace regular maintenance therapy. It must be used as an add-on treatment for patients already receiving carbidopa/levodopa. There are currently no boxed warnings or Risk Evaluation and Mitigation Strategies (REMS) required for this medication.

Safety Monitoring

While no major safety communications or recalls have been issued, the FDA requires the medication to be used only with the specific inhaler device provided. Patients are monitored for potential respiratory issues, as the drug is inhaled into the lungs.

Question 11

What should I know about Inbrija and cost?

Accepted Answer

Insurance and Medicare Coverage

The out-of-pocket cost for Inbrija varies based on your specific health insurance plan. Many commercial insurance and Medicare Part D plans cover the medication, but it may be subject to prior authorization or placed in a higher cost tier, which can affect your copayment amount.

Brand-Name Status

Inbrija is currently available only as a brand-name medication. There is no generic version available at this time, which generally means the cost will be higher than for generic Parkinson's medications.

Financial Assistance

Patients may be able to reduce their costs through manufacturer-sponsored programs. These often include copay savings cards for those with private insurance or patient assistance programs for individuals who meet certain income requirements or lack insurance coverage.

Pharmacy Variations

Prices can fluctuate between different pharmacies. Some insurance plans may require you to use a specific specialty pharmacy to fill your prescription for the Inbrija inhaler and capsules.
