What is the mechanism of action of apomorphine?
Apomorphine is a non-ergoline dopamine agonist with high binding affinity to dopamine D2, D3, and D5 receptors. Stimulation of D2 receptors in the caudate-putamen, a region of the brain responsible for locomotor control, may be responsible for apomorphine's action.
What does apomorphine do to the body?
Apokyn (apomorphine hydrochloride injection) is a dopamine agonist, which works by helping restore the balance of dopamine in the brain, used to treat "wearing-off" episodes (muscle stiffness, loss of muscle control) in people with advanced Parkinson's disease.
Is apomorphine a form of morphine?
Contrary to its name, apomorphine does not actually contain morphine or its skeleton, nor does it bind to opioid receptors. The apo- prefix relates to it being a morphine derivative ("[comes] from morphine").
What is the main action of apomorphine in a patient with Parkinson's disease?
Apokyn (apomorphine) is used by injection to treat loss of body movement control in patients with advanced Parkinson's disease between doses of levodopa treatment. It has the same effect as dopamine, a naturally occurring chemical messenger found in the brain.
How does apomorphine work for erectile dysfunction?
Apomorphine is a novel, oral erectogenic agent taken sublingually. It exerts its effect on hypothalamic centres involved in the triggering of the erection cascade. It dissolves rapidly and results in an erection in responders in approximately 20 min.
Where does the apomorphine act to cause the emesis?
APOMORPHINE (6.25-MG TABLETS).
Apomorphine acts directly on the chemoreceptor trigger zone to induce emesis. Apomorphine is generally the emetic of choice because of its rapid onset and the ability to reverse its action.
Is apokyn a dopamine agonist?
Apokyn (apomorphine hydrochloride injection) is a dopamine agonist, which works by helping restore the balance of dopamine in the brain, used to treat "wearing-off" episodes (muscle stiffness, loss of muscle control) in people with advanced Parkinson's disease.
Is bromocriptine a dopamine agonist?
Bromocriptine is a sympatholytic D2-dopamine agonist that has been approved for the treatment of type 2 diabetes.
Is apomorphine a dopamine agonist?
Apomorphine injection is in a class of medications called dopamine agonists. It works by acting in place of dopamine, a natural substance produced in the brain that is needed to control movement.
What is apomorphine challenge?
The apomorphine challenge test has at least 80% overall predictive ability to clinically diagnose Parkinson's disease across the different stages of the disease and parkinsonian syndromes.
Does apomorphine cross the blood brain barrier?
The hydrophilic character of apomorphine allows it to be solubilized and therefore, formulated as an aqueous solution. Moreover, it is readily mixed in tissue fluids and can be absorbed into the systemic circulation and subsequently cross the lipophilic blood-brain barrier [14].
Why is apomorphine controlled?
Currently, apomorphine is classified as a schedule II controlled substance, a classification that is generally defined by drugs that have an accepted medical value, present a high potential for abuse, and may lead to severe psychological or physical dependence if abused.
Can apomorphine help Parkinsons?
Apomorphine is the oldest dopaminergic drug available for Parkinson's disease, and—to date—it remains the only drug with efficacy comparable to that of levodopa. Subcutaneous apomorphine, delivered as a continuous infusion or as intermittent injections, has proven well-tolerated and effective.
What do dopamine agonists do?
Dopamine agonists (DA) are medications that work by imitating the actions of dopamine when levels are low. These medications improve condition-related symptoms by fooling the brain into thinking dopamine is available.
