4.2 Drug Indication

Sifrol is indicated for treatment of the signs and symptoms of idiopathic Parkinson's disease, alone (without levodopa) or in combination with levodopa, i. e. over the course of the disease, though to late stages when the effect of levodopa wears off or becomes inconsistent and fluctuations of the therapeutic effect occur (end-of-dose or 'on-off' fluctuations).

Sifrol is indicated for symptomatic treatment of moderate to severe idiopathic restless-legs syndrome in dosages up to 0. 54 mg of base (0. 75 mg of salt).


Mirapexin is indicated for treatment of the signs and symptoms of idiopathic Parkinson's disease, alone (without levodopa) or in combination with levodopa, i. e. over the course of the disease, through to late stages when the effect of levodopa wears off or becomes inconsistent and fluctuations of the therapeutic effect occur (end-of-dose or 'on-off' fluctuations).

Mirapexin is indicated for symptomatic treatment of moderate to severe idiopathic restless-legs syndrome in dosages up to 0. 54 mg of base (0. 75 mg of salt).


Oprymea is indicated for treatment of the signs and symptoms of idiopathic Parkinson's disease, alone (without levodopa) or in combination with levodopa, i. e. over the course of the disease, through to late stages when the effect of levodopa wears off or becomes inconsistent and fluctuations of the therapeutic effect occur (end of dose or "on off" fluctuations).

Oprymea is indicated in adults for symptomatic treatment of moderate to severe idiopathic Restless Legs Syndrome in doses up to 0. 54 mg of base (0. 75 mg of salt) (see section 4. 2).


Pramipexole Teva is indicated for treatment of the signs and symptoms of idiopathic Parkinson's disease, alone (without levodopa) or in combination with levodopa, i. e. over the course of the disease, through to late stages when the effect of levodopa wears off or becomes inconsistent and fluctuations of the therapeutic effect occur (end-of-dose or 'on-off' fluctuations).

Pramipexole Teva is indicated in adults for symptomatic treatment of moderate to severe idiopathic Restless Legs Syndrome in doses up to 0. 54 mg of base (0. 75 mg of salt) (see section 4. 2).


Pramipexole Accord is indicated in adults for treatment of the signs and symptoms of idiopathic Parkinson's disease, alone (without levodopa) or in combination with levodopa, i. e. over the course of the disease, through to late stages when the effect of levodopa wears off or becomes inconsistent and fluctuations of the therapeutic effect occur (end-of-dose or 'on-off' fluctuations).


DAQUIRAN tablets are indicated for treatment of the signs and symptoms of advanced idiopathic Parkinson's disease in combination with levodopa, i. e. over the course of the disease, when the effect of levodopa wears off or becomes inconsistent and fluctuations of the therapeutic effect occur (end of dose or "on off" fluctuations).

5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Antiparkinson Agents

Agents used in the treatment of Parkinson's disease. The most commonly used drugs act on the dopaminergic system in the striatum and basal ganglia or are centrally acting muscarinic antagonists. (See all compounds classified as Antiparkinson Agents.)


Antioxidants

Naturally occurring or synthetic substances that inhibit or retard oxidation reactions. They counteract the damaging effects of oxidation in animal tissues. (See all compounds classified as Antioxidants.)


Dopamine Agonists

Drugs that bind to and activate dopamine receptors. (See all compounds classified as Dopamine Agonists.)
