How Did Kynmobi Work?

Apomorphine stimulates dopamine receptors. Its effect on Parkinson off episodes is thought to involve stimulation of postsynaptic dopamine D2-type receptors in the caudate-putamen.

Who Used Kynmobi?

Kynmobi was used as needed for acute off episodes in patients with Parkinson disease. Dose initiation and titration occurred under healthcare professional supervision. Concomitant use with 5-HT3 antagonists such as ondansetron, granisetron, dolasetron, or palonosetron was contraindicated due to reports of profound hypotension and loss of consciousness.

How Was Kynmobi Dosed?

The initial dose was 10 mg placed under the tongue. Doses could increase in 5 mg steps until symptom control was reached with acceptable tolerability, within a range of 10 mg to 30 mg. Doses were separated by at least two hours, with no more than five doses per day and no more than 30 mg for a single off episode.

What Serious Risks Were Linked to Kynmobi?

Serious concerns included nausea and vomiting, sudden sleep episodes, somnolence, syncope, orthostatic hypotension, falls, hallucinations, psychotic behavior, impulse-control problems, withdrawal-related fever and confusion, QTc prolongation, and priapism. Oral mucosal irritation also occurred.
