Mirapex PD, 1.5 mg 30 pcs
€42.49 €36.83
Mirapex PD is an antiparkinsonian drug – dopamine receptor agonist. With high selectivity and specificity it binds to dopamine receptors of subgroup D2, of which it has the most pronounced affinity for D3 receptors.
It reduces motor deficits in Parkinson’s disease by stimulating dopamine receptors in the striatum. Pramipexole inhibits the synthesis, release and metabolism of dopamine. In vitro, pramipexole protects dopamine neurons from degeneration occurring in response to ischemia or methamphetamine neurotoxicity.
Pramipexole in vitro protects neurons from levodopa neurotoxicity.
Decreases prolactin secretion (dose-dependent).
In clinical studies in healthy volunteers in whom the dose of Mirapex PD was increased faster than necessary (every 3 days) up to 4.5 mg/day, an increase in BP and HR was observed. This effect was not observed in patient studies.
Pharmacokinetics
Intake and distribution
Pramipexole is quickly and completely absorbed after oral administration. Absolute bioavailability is greater than 90% and Cmax in plasma is reached after approximately 6 h. As a rule, food intake does not affect the bioavailability of pramipexole.
A slight increase, approximately 20%, in Cmax and a delay, approximately 2 h, in time to reach Cmax after a fatty meal are not clinically significant.
Pramipexole exhibits linear kinetics and relatively little variability in plasma levels between patients, regardless of pharmaceutical form. Pramipexole binds very little to plasma proteins (
Metabolism and excretion
It is metabolized to a negligible degree.
About 90% of the dose is excreted through the kidneys (80% unchanged) and less than 2% is found in the feces. Total clearance of pramipexole is about 500 ml/min, renal clearance is about 400 ml/min. T1/2 fluctuates from 8 h in young adults to 12 h in the elderly.
Indications
Parkinson’s disease.
Active ingredient
Composition
Active ingredient:
pramipexole dihydrochloride monohydrate 1.5 mg;
Excipients:
Hypromellose 2208,

How to take, the dosage
Long-acting tablets should be taken once a day, at approximately the same time of day. The tablets should be swallowed whole with water and should not be chewed, crushed or crushed. The tablets may be taken with or without food.
If the time of the next dose has been missed, the daily dose should be taken if no more than 12 hours have passed since the usual time of taking the medicine. If more than 12 hours have passed, you should not take the medication; the next dose should be taken the next day at the usual time.
Patients who are already taking Mirapex tablets may be switched to taking Mirapex PD long-acting tablets overnight, at the same dose.
Interaction
Pramipexole to a small degree
Drugs that inhibit active renal tubular secretion of cationic drugs (e.g., cimetidine), or that are themselves excreted by active renal tubular secretion, may interact with pramipexole, which is reflected in decreased clearance of one or both drugs.
If such drugs (including amantadine) and pramipexole are used concomitantly, watch out for signs of excessive dopamine stimulation such as dyskinesia, agitation or hallucinations. In such cases, the dose should be reduced.
Selegyline and levodopa do not affect the pharmacokinetics of pramipexole. Pramipexole does not affect the overall absorption or elimination of levodopa. Interaction with anticholinergic drugs and amantadine has not been studied.
However, interaction with amantadine is possible because the drugs have a similar excretion mechanism. Anticholinergic drugs are mostly excreted metabolically, so interactions with pramipexole are unlikely.
Lower doses of levodopa are recommended when increasing the dose in patients with Parkinson’s, and the dose of other antiparkinsonian medications must be maintained at a constant level.
Because of possible cumulative effects, patients should be advised to exercise caution when taking other sedative medications or alcohol in combination with Mirapex PD, as well as when taking concomitant medications that increase plasma concentrations of pramipexole (e.g., cimetidine).
