Researchers have also found that an acute dose of dopamine antagonist
haloperidol reduced the amplitude of the ERG in humans (Holopigian et al.
APD421 comprises a low dose intravenous formulation of the marketed dopamine antagonist
amisulpride, which Acacia Pharma has repurposed for the completely new, patent-protected use of management of PONV.
Domperidone is a dopamine antagonist
that cannot cross the blood-brain barrier, so is useful for limiting non-motor symptoms and dopaminergic drug effects.
Breast-feeding women should not take the dopamine antagonist
domperidone to induce or increase lactation, because the drug may put them at risk of developing a fatal cardiac arrhythmia, the Food and Drug Administration has warned.
Testing with the dopamine antagonist
, domperidone, (10 mg, administered intravenously) produced a normal increase in serum prolactin 30 min after administration (basal prolactin, 663 mIU/L, increasing to 5220 mIU/L; prolactin measured at our endocrine center).
APD403 is a novel and proprietary product containing the dopamine antagonist
amisulpride, which Acacia Pharma is also developing as APD421 for the prevention and treatment of post-operative nausea & vomiting (PONV).
drugs may act centrally, or can increase gastric emptying and contraction of the gastro-oesophageal sphincter to reduce nausea, reflux and vomiting.
5) Dopamine release was defined as amphetamine-induced changes in the ability of the dopamine antagonist
raclopride to bind to dopamine receptors.
If nausea is present or if the pain is escalating, then the patient can add a dopamine antagonist
, but no more than twice a week; these drugs are helpful in treating pain and also speed up NSAID absorption.
Data generated by Acacia Pharma in Phase 2 and Phase 3 clinical trials indicate that APD421, its proprietary low dose intravenous formulation of the marketed dopamine antagonist

haloperidol (Haldol(r)), a medication commonly prescribed to treat severe psychiatric illness (Modell et al.
Our clinical data indicate APD421 is an effective dopamine antagonist
antiemetic, which has the potential to become a mainstay of therapy, contributing greatly to the well-being of patients following surgery.
