About Inbrija: This medication is used when needed to treat the return of Parkinson's symptoms (known as OFF episodes) in people with Parkinson's disease who are treated with carbidopa/levodopa medicines. Show more ▾

Parkinson's disease tends to worsen over time, and you may need extra levodopa from time to time to keep symptoms (such as shakiness, stiffness, difficulty moving) from returning. This medication does not replace your regular carbidopa/levodopa medicine. Keep taking your carbidopa/levodopa medicine regularly as directed by your doctor. Parkinson's disease is thought to be caused by too little of a naturally occurring substance (dopamine) in the brain. Levodopa changes into dopamine in the brain, helping to control movement. The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system.

In 2024, this provider wrote 13 Medicare prescriptions for Inbrija, about 61% of the volume of the typical District Of Columbia prescriber of this medication (21.3). Medicare paid an average of $3,747.38 per fill, versus $3,284.68 statewide.

About this data. The prescription history for GONUL D OZAY MD is compiled from the Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescriber Public Use File for calendar year 2024, the most recent federal release.

Reading the costs. Drug costs are gross amounts paid to pharmacies under Part D, including both plan and beneficiary payments. They are not the price a patient pays at the pharmacy counter. Medications with fewer than 11 claims are excluded from the federal source data, and state comparisons use the average among DC prescribers of the same medication and form, shown only when at least five prescribers contribute. Always confirm current medications and costs directly with the provider and your plan.

About the medication summaries. Drug use descriptions come from the CMS Medicare Part D Drug Spending Dashboard (2024), and substance definitions from Medical Subject Headings (MeSH) 2026, U.S. National Library of Medicine. They are summaries that do not contain all possible information about a medication and are not individual medical advice.
