Treat patients with symptomatic and supportive measures.
The intraperitoneal LD50 in mice is 145µg/kg.
[L14012]
Given the incidence of nausea and vomiting in patients taking apomorphine, treatment with [trimethobenzamide] may be recommended prior to or during therapy. Antiemetic pretreatment may be started three days prior to beginning therapy with apomorphine - it should only be continued as long as is necessary and generally for no longer than two months.[L41915]
How the body processes this drug — absorption, distribution, metabolism, and elimination
[A203549]
The Cmax and AUC of apomorphine vary significantly between patients, with 5- to 10-fold differences being reported.

It can be glucuronidated by various UGTs,[L13919] or sulfated by SULTs 1A1, 1A2, 1A3, 1E1, and 1B1.
[A203447]
Approximately 60% of sublingual apomorphine is eliminated as a sulfate conjugate, though the structure of these sulfate conjugates are not readily available.
[A203447][L13919]
The remainder of an apomorphine dose is eliminated as apomorphine glucuronide and norapomorphine glucuronide.
[L13919]
Only 0.3% of subcutaneous apomorphine is recovered as the unchanged parent drug.
[A203402]
[L13919][L13922]
A study in rats has shown apomorphine is predominantly eliminated in the urine.

Regulates the transvesicular monoaminergic gradient that determines the quantal size.
Mediates somatodendritic dopamine release in hippocampal neurons, likely as part of a regulated secretory pathway that integrates retrograde synaptic signals (By similarity). Acts as a primary transporter for striatal dopamine loading ensuring impulse-dependent release of dopamine at the synaptic cleft (By similarity).

Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity).
Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity).
Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli .
