Apomorphine is a dopamine agonist used to treat Parkinson's disease symptoms, primarily motor fluctuations. It is administered as an injection or infusion for acute, intermittent treatment of "off" episodes.
When does the apomorphine patent expire?
The patent landscape for apomorphine is complex, with multiple patents covering different aspects of its formulation, delivery, and use. For specific patent expiration dates, resources like DrugPatentWatch.com can provide detailed information [1].
What are the different forms of apomorphine available?
Apomorphine is available in different formulations. One common form is an injection, which provides rapid relief for "off" episodes in Parkinson's disease. There are also sublingual films that dissolve under the tongue.
How does apomorphine compare to other Parkinson's medications?
Apomorphine is typically used as a rescue therapy for sudden "off" periods when oral medications are not working quickly enough. It offers faster onset of action compared to many oral dopamine agonists or levodopa, but its use is limited by its administration method and potential side effects [2].
What are the risks and side effects of apomorphine?
Common side effects of apomorphine include nausea, vomiting, dizziness, and drowsiness. More serious side effects can include hallucinations, confusion, and a condition known as falling onto the floor or involuntary movements, dyskinesia. It can also cause injection site reactions [2]. Patients are often advised to take an anti-nausea medication along with apomorphine.
Who makes apomorphine?
Several pharmaceutical companies are involved in the manufacturing and marketing of apomorphine products. For instance, U.S. WorldMeds markets apomorphine hydrochloride injection under the brand name KORSUVA [3].
Can generic apomorphine be accessed?
The availability of generic apomorphine depends on patent expirations and regulatory approvals. As patents for specific formulations or delivery systems expire, generic versions may become available, potentially reducing costs [1]. However, complex formulations or delivery devices can sometimes present challenges for generic manufacturers.
