INBRIJA Positioned for Stronger Market Penetration as Demand Grows for Inhaled Parkinson's Therapy| DelveInsight
INBRIJA is an inhalable dry powder formulation of levodopa designed for use with the INBRIJA inhaler. The medication is delivered via white hypromellose capsules, each containing 42 mg of levodopa in a spray-dried powder form, along with excipients such as 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and sodium chloride.
Levodopa, the active ingredient in INBRIJA, is an aromatic amino acid with the chemical name (2S)-2-amino-3-(3,4-dihydroxyphenyl)propanoic acid. Its molecular formula is C₉H₁₁NO₄, and it has a molecular weight of 197.19 g/mol.
INBRIJA is indicated for the intermittent relief of OFF episodes in patients with Parkinson's disease who are already receiving treatment with carbidopa/levodopa. It is not intended to replace regular carbidopa/levodopa therapy but is used to reduce OFF periods and improve motor symptoms.
Each therapeutic capsule is used with a specially designed plastic inhaler featuring a blue body, blue cap, and a white mouthpiece. Patients may use INBRIJA up to five times per day, with the maximum daily dose limited to 420 mg.

Parkinson's disease is a chronic and progressive neurological condition that primarily affects the ability to control movement. It is caused by the gradual loss of dopamine-producing neurons in the brain, particularly in the substantia nigra—a region vital for regulating voluntary muscle activity. According to DelveInsight, there were approximately diagnosed prevalent cases of Parkinson's disease across the 7MM in 2024, with the United States accounting for about 45% of these. Although there is currently no cure, symptom management involves a mix of medications and supportive therapies. Treatment typically includes physical, occupational, and speech therapy, and certain patients may benefit from surgical interventions. Complementary therapies are also sometimes used to help manage specific symptoms.
Commonly used drugs for Parkinson's include . These medications primarily aim to alleviate motor symptoms, which significantly impact patients' quality of life. DelveInsight estimates the Parkinson's disease market in the 7MM to have been worth in 2024. DelveInsight's analysis forecasts market growth due to the introduction of emerging therapies, expecting a rise in market size during the study period (2020–2034). The anticipated increase in market size is driven by advancements in treatment options, greater healthcare access, and a rising prevalence of the condition, which together foster higher demand for innovative and effective therapies.

Some of the emerging competitors to INBRIJA in the Parkinson's disease treatment landscape include (Cerevance) (Annovis Bio) (Roche/Protherna) (Jupiter Neurosciences), (UCB Biopharma), and others. In reported that the pivotal Phase III ARISE trial evaluating Solengepras as an adjunctive treatment for Parkinson's disease was ongoing, with topline results expected in the first half of 2026.
Cerevance's GPR6 antagonist, Solengepras, did not meet its primary endpoint in the Phase II ASCEND trial as a monotherapy for early, untreated Parkinson's disease patients, demonstrating only a modest and statistically non-significant improvement compared to placebo, as reported at AD/PD 2025.
According to the results presented at AD/PD 2025, has been shown to prevent cognitive decline across the entire treated ITT population. In patients with existing cognitive impairment, it improved cognitive performance along with MDS-UPDRS, WAIS, and CGI-S scores. A meeting with the US FDA to discuss the future development strategy is scheduled for the second Quarter of 2025.
The design for was presented at AD/PD 2025, highlighting its potential as a Parkinson's treatment. As a D1PAM, it boosts dopamine signaling without directly activating receptors.
