Rotigotine
 

Rotigotine (Neupro) is a non-ergoline dopamine agonist indicated for the treatment of Parkinson's disease (PD) and restless legs syndrome (RLS) in Europe and the United States. It is formulated as a once-daily transdermal patch which provides a slow and constant supply of the drug over the course of 24 hours. Like other dopamine agonists, rotigotine has been shown to possess antidepressant effects and may be useful in the treatment of depression as well. Rotigotine was developed by Aderis Pharmaceuticals. In 1998, Aderis licensed worldwide development and commercialization rights for rotigotine to the German pharmaceutical company Schwarz Pharma (today a subsidiary of the Belgian company UCB S.A.). The drug has been approved by the EMEA for use in Europe in 2006 and is today being sold in several European countries. In 2007, the Neupro patch was approved by the Food and Drug Administration (FDA) as the first transdermal treatment of Parkinson's disease in the United States. However, as of 2008, Schwarz Pharma has recalled all Neupro patches in the United States and some in Europe because of problems with the delivery mechanism. Rotigotine has been authorized as a treatment for RLS since August 2008.

indication

For use/treatment in neurologic disorders and parkinson's disease as well as moderate-to-severe primary Restless Legs Syndrome.

pharmacology

There is no indication of a QT/QTc prolonging effect of Neupro in doses up to 24 mg/24 hours. The effects of Neupro at doses up to 24 mg/24 hours (supratherapeutic doses) on the QT/QTc interval was evaluated in a double-blind, randomized, placebo- and positive-controlled (moxifloxacin 400 mg IV, single dose) parallel-group trial with an overall treatment period of 52 days in male and female patients with advanced-stage Parkinson's disease. Assay sensitivity was confirmed by significant QTc prolongation by moxifloxacin.

mechanism of action

Rotigotine, a member of the dopamine agonist class of drugs, is delivered continuously through the skin (transdermal) using a silicone-based patch that is replaced every 24 hours. A dopamine agonist works by activating dopamine receptors in the body, mimicking the effect of the neurotransmitter dopamine. The precise mechanism of action of rotigotine as a treatment for Restless Legs Syndrome is unknown but is thought to be related to its ability to stimulate dopamine

toxicity

The most likely symptoms of overdose would be those related to the pharmacodynamic profile of a dopamine agonist, including nausea, vomiting, hypotension, involuntary movements, hallucinations, confusion, convulsions, and other signs of excessive dopaminergic stimulation.

biotransformation

Hepatic (CYP-mediated).

absorption

Bioavailability is 37% (transdermal)

half life

After removal of the patch, plasma levels decreased with a terminal half-life of 5 to 7 hours. The pharmacokinetic profile showed a biphasic elimination with an initial half-life of 3 hours.

route of elimination

Urine (71%), Fecal (23%)

drug interactions

Thiothixene: Thiothixene may antaonize the effects of the anti-Parkinsonian agent, Rotigotine. Consider alternate therapy or monitor for decreased effects of both agents.

Triprolidine: The CNS depressants, Triprolidine and Rotigotine, may increase adverse/toxic effects due to additivity. Monitor for increased CNS depressant effects during concomitant therapy.

Ziprasidone: The atypical antipsychotic, ziprasidone, may antagonize the effect of the dopamine agonist, rotigotine. Consider alternate therapy or monitor for worsening of movement disorder.

Zuclopenthixol: Antagonism may occur between zuclopenthixol, a dopamine D2 receptor antagonist, and rotigotine, 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.
