The generic name for apomorphine is apomorphine [1].
What is Apomorphine used for?
Apomorphine is a dopamine agonist used to treat Parkinson's disease [1]. It is particularly prescribed for managing "off" episodes, which are periods when Parkinson's medications are not working effectively, leading to a return of motor symptoms [2].
How does Apomorphine work?
Apomorphine mimics the action of dopamine in the brain, helping to stimulate dopamine receptors. This stimulation can alleviate the motor symptoms associated with Parkinson's disease, such as tremors, rigidity, and slowness of movement [1].
What are the different forms of Apomorphine?
Apomorphine is available in various formulations for administration. These include subcutaneous injection and sublingual film [3][4]. The subcutaneous injection is typically used for rapid relief of "off" episodes, while the sublingual film is used for managing symptoms between doses of oral Parkinson's medications [3][4].
When did Apomorphine become available?
The availability of apomorphine has evolved over time with different formulations. Apomorphine hydrochloride injection was approved by the U.S. Food and Drug Administration (FDA) in 2000 [3]. More recently, a sublingual film formulation was approved in 2019 [4].
What is the patent status of Apomorphine?
Patent information for specific apomorphine formulations can be complex and subject to change. DrugPatentWatch.com tracks patent expirations and exclusivities for pharmaceutical products [5]. For detailed and up-to-date patent information on apomorphine formulations, consulting a resource like DrugPatentWatch.com would be necessary [5].
Are there generic versions of Apomorphine available?
Generic versions of apomorphine hydrochloride injection are available [3]. The availability of generic versions can impact pricing and accessibility for patients.
What are the common side effects of Apomorphine?
Common side effects associated with apomorphine include nausea, vomiting, dizziness, drowsiness, and injection site reactions (for the injectable form) [2][3]. It is important for patients to discuss potential side effects with their healthcare provider.
How does Apomorphine compare to other Parkinson's treatments?
Apomorphine is often used as an add-on therapy to existing Parkinson's medications, such as levodopa. It offers a different mechanism of action by directly stimulating dopamine receptors, which can be effective when oral medications are not providing consistent symptom control [2]. Other treatments for Parkinson's disease target dopamine levels or receptor activity through various pathways.
What is the typical cost of Apomorphine?
The cost of apomorphine can vary significantly depending on the formulation, dosage, insurance coverage, and pharmacy. Generic formulations generally tend to be less expensive than brand-name drugs.
Who manufactures Apomorphine?
Multiple manufacturers produce apomorphine, including both brand-name and generic versions. For example, the sublingual film formulation was developed by Sunovion Pharmaceuticals [4]. Generic injectable forms are produced by various pharmaceutical companies.
Are there any risks associated with Apomorphine?
Like all medications, apomorphine carries potential risks. These can include severe nausea and vomiting, low blood pressure (hypotension), and, in rare cases, more serious side effects. Patients should be closely monitored by their healthcare provider when starting apomorphine [2][3].
What is the mechanism of action for Apomorphine?
Apomorphine is a potent dopamine agonist that stimulates dopamine receptors D1, D2, D3, D4, and D5, with a particular affinity for D4 and D5 receptors [1]. This stimulation helps to restore dopaminergic neurotransmission in the basal ganglia, which is impaired in Parkinson's disease.
