Dược Lực Học :
Apomorphine is a type of dopaminergic agonist, a morphine derivative which primarily affects the hypothalamic region of the brain. Drugs containing this substance are sometimes used in the treatment of Parkinson's disease or erectile dysfunction. In higher doses it is a highly effective emetic.
Cơ Chế Tác Dụng :
A derivative of morphine that is a dopamine D2 agonist. It is a powerful emetic and has been used for that effect in acute poisoning. It has also been used in the diagnosis and treatment of parkinsonism, but its adverse effects limit its use. [PubChem]
The precise mechanism of action of apomorphine as a treatment for Parkinson's disease is unknown, although it is believed to be due to stimulation of post-synaptic dopamine D2-type receptors within the brain. Apomorphine has been shown to improve motor function in an animal model of Parkinson's disease. In particular, apomorphine attenuates the motor deficits induced by lesions in the ascending nigrostriatal dopaminergic pathway with the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in primates.

Tương Tác Thuốc :
-
Artemether
Additive QTc-prolongation may occur. Concomitant therapy should be avoided.
-
Entacapone
Entacapone increases the effect and toxicity of the sympathomimetic, apomorphine.
-
Lumefantrine
Additive QTc-prolongation may occur. Concomitant therapy should be avoided.
-
Paliperidone
The atypical antipsychotic agent, paliperidone, may decrease the therapeutic effect of the anti-Parkinson's agent, apomorphine. This interaction may be due to the dopamine antagonist properties of paliperidone. Consider an alternate antipsychotic in those with Parkinson's disease or consider using clozapine or quetiapine if an atypical antipsychotic is necessary.
-
Tacrolimus
Additive QTc-prolongation may occur increasing the risk of serious ventricular arrhythmias. Concomitant therapy should be used with caution.
-
Thiothixene
May cause additive QTc-prolonging effects. Increased risk of ventricular arrhythmias. Thiothixene may also antagonize the effects of the anti-Parkinsonian agent, Apomorphine. Consider alternate therapy or monitor for changes in the therapeutic and adverse effects of both agents if concomitant therapy is initiated, discontinued or doses changed.
-
Toremifene
Additive QTc-prolongation may occur, increasing the risk of serious ventricular arrhythmias. Consider alternate therapy. A thorough risk:benefit assessment is required prior to co-administration.
-
Voriconazole
Additive QTc prolongation may occur. Consider alternate therapy or monitor for QTc prolongation as this can lead to Torsade de Pointes (TdP).
-
Vorinostat
Additive QTc prolongation may occur. Consider alternate therapy or monitor for QTc prolongation as this can lead to Torsade de Pointes (TdP).
-
Ziprasidone
Additive QTc-prolonging effects may increase the risk of severe arrhythmias. Concomitant therapy is contraindicated.
-
Zuclopenthixol
Additive QTc prolongation may occur. Consider alternate therapy or use caution and monitor for QTc prolongation as this can lead to Torsade de Pointes (TdP). Antagonism may also occur between zuclopenthixol, a dopamine D2 receptor antagonist, and apomorphine, a dopamine agonist. Consider alternate therapy or monitor for changes in the therapeutic and adverse effects of both agents if concurrent therapy is initiated, discontinued or dose(s) changed.
