N.04.B.C.05   Pramipexole

Pharmacodynamics:

Pramipexole, a dopamine receptor agonist, with high selectivity and specificity binds to dopamine D2receptors, has a pronounced affinity for dopamine D3receptors.

Reduces the lack of motor activity in Parkinson's disease by stimulating dopamine receptors in the striatum.

Pramipexole inhibits synthesis, release and metabolism of dopamine, protects dopaminergic neurons from degeneration arising in response to ischemia or methamphetamine neurotoxicity.

Clinical studies have shown the effectiveness of pramipexole therapy in the late stages of Parkinson's disease, in which there was a significant reduction in the number of motor disorders and a much later development of complications compared with monotherapy with levodopa.

Pharmacokinetics:

Suction. Pramipexole after intake quickly and completely absorbed, reaching the maximum concentration in the plasma (CmOh) after about 1-3 hours. Absolute bioavailability of pramipexole exceeds 90%. The rate of absorption decreases with food intake, but the total intake is not affected by food intake. Pramipexole is characterized by linear kinetics and a relatively small variability in the concentrations between individual patients.

Distribution. Volume of distribution (Vd) is 400 liters. Binding to plasma proteins - less 20%.

Metabolism and excretion. Slightly metabolized in the body. About 90% of the dose is excreted by the kidneys (80% - unchanged) and less than 2% - with feces. The total clearance of pramipexole is about 500 ml / min, the renal clearance is about 400 ml / min. The value of the final half-life (T1/2) is 8 hours in young healthy volunteers and about 12 hours - in the elderly.

Indications:

Symptomatic treatment of Parkinson's disease as a monotherapy or in combination with drugs of levodopa at a late stage of the disease, when the effects of levodopa become weakened or become unstable and fluctuations of the therapeutic effect (on-off) occur.

Contraindications:

Hypersensitivity to pramipexole or any of the components of the drug; the period of breastfeeding; age to 18 years.

Carefully:

Renal failure, arterial hypotension, cardiovascular diseases, simultaneous use with dopamine receptor agonists, sedatives, cimetidine, amantadine, ethanol, pregnancy.

Pregnancy and lactation:

The possibility of using the drug during pregnancy and during breastfeeding in humans has not been investigated.

Pregnancy

The possible effect of pramipexole on reproductive function was studied in animal experiments. Pramipexole does not show teratogenicity in rats and rabbits, but at doses toxic to pregnant females, it was embryotoxic in rats.

During pregnancy, the drug should be given only if the potential benefit to the mother exceeds the potential risk to the fetus.

Breast-feeding

Excretion of the drug with breast milk has not been studied. The concentration of the drug in the milk of rats was higher than in plasma. Because the pramipexole inhibits the secretion of prolactin, we can assume that it also suppresses lactation. Therefore, the drug should not be taken during breastfeeding.

Fertility

The effect on fertility in humans has not been studied. The results of studies conducted on animals do not indicate the presence of direct or indirect signs of adverse effects on fertility in males.

Dosing and Administration:

Inside, regardless of food intake, with enough liquid. The daily dose should be evenly divided into 3 divided doses.

Doses of the drug Pramipexole-Teva, described in the literature, refer to the salt form. Thus, the doses will be expressed in the form of a base and in the form of salt (in parentheses). The initial daily dose of 264 μg of pramipexole base (375 μg of pramipexole dihydrochloride) should be increased every 5-7 days. To reduce side effects, the dose should be selected gradually until the maximum therapeutic effect is achieved (see Table).

If it is necessary to further increase the daily dose, 540 μg pramipexole base (750 μg pramipexole dihydrochloride) is added weekly to a maximum daily dose of 4.5 mg.

The incidence of drowsiness increases with a daily dose of more than 1.5 mg. The individual maintenance daily dose is from 264 μg pramipexole base (375 μg pramipexole dihydrochloride) to 3.3 mg pramipexole base (4.5 mg pramipexole dihydrochloride). At both early and late stages of the disease, the drug Pramipexol-Teva was effective starting at a daily dose of 1.5 mg. It is not excluded that in some patients doses above 1.5 mg per day can give an additional therapeutic effect, especially at a late stage of the disease, when a decrease in the dose of levodopa is indicated.

With simultaneous therapy with levodopa, it is recommended to lower the dose of levodopa as the dose increases, and during maintenance therapy with Pramipexol-Teva. This is necessary to avoid excessive dopaminergic stimulation.

With a sharp cessation of therapy with Pramipexol-Teva, a malignant neuroleptic syndrome may develop, so the drug should be withdrawn gradually over several days. The dose should be reduced by 540 μg pramipexole base (750 μg pramipexole dihydrochloride) per day until the daily dose is 540 μg pramipexole base (750 μg pramipexole dihydrochloride).The dose should then be reduced to 264 μg pramipexole base (375 μg pramipexole dihydrochloride) per day.

Patients with kidney failure

For initial therapy in patients with creatinine clearance (CK) of more than 50 ml / min, a daily dose reduction is not required.

In patients with SC from 20 to 50 ml / min, the initial daily dose of the drug Pramipexole-Teva should be divided into 2 doses and begin with a dose of 88 μg pramipexole base (125 μg pramipexole dihydrochloride) 2 times a day, daily dose of 176 μg pramipexole base (250 μg pramipexole dihydrochloride).

Patients with SC less than 20 ml / min show a single intake of the entire daily dose, starting with a dose 88 μg pramipexole base (125 μg pramipexole dihydrochloride) per day.

If the function of the kidneys decreases against the background of maintenance therapy, the daily dose of Pramipexol-Teva is reduced by the same percentage as the decrease in QC (for example, if the CC decreased by 30%, the daily dose should also be reduced by 30%).

The daily dose should be divided into 2 doses, if the CK value is 20-50 ml / min.

The drug Pramipexol-Teva should be taken 1 time per day, if the SC is less than 20 ml / min.

Patients with hepatic failure

Dose adjustments for patients with liver failure are not required.

Side effects:

When using Pramipexole-Teva, the following side effects are listed: abnormal behavior (symptoms of impulsive and compulsive actions) such as a tendency to overeating (hyperphagia), obsessive desire to shop (pathological shopping), hypersexuality and pathological craving for gambling, abnormal dreams, amnesia, confusion, constipation, delirium, dizziness, dyskinesia, dyspnoea, weakness, hallucinations, headache, hiccups, hyperkinesia, hyperphagia, hypotension, insomnia, libido disorders, t nausea, paranoia, peripheral edema, pneumonia, pruritus, rash and other hypersensitivity reactions, anxiety, drowsiness, sudden falling asleep, fainting, blurred vision (including diplopia, decreased visual acuity and clear perception), vomiting, weight loss, including decreased appetite .

The risk of a sharp decrease in blood pressure during therapy with Pramipexol-Teva is not higher than in the treatment of placebo. However, hypotension may occur in some patients at the beginning of treatment, especially if the dose is increased too quickly.With therapy with the drug Pramipexol-Teva, libido disorders (increase or decrease) can be associated.

Patients receiving pramipexole, reported a sudden fall asleep during daytime activity, including driving, which sometimes led to traffic accidents. At the same time, some of them did not report having anxious signs such as drowsiness, often observed in patients taking pramipexole tablets at doses above 1.5 mg per day, which, according to modern knowledge of the physiology of sleep, always lead to sudden falling asleep. A clear connection with the duration of treatment was not revealed. At the same time, some patients took other drugs with potentially sedative properties. In most cases where such information was available, there were no such episodes after a dose reduction or discontinuation of treatment.

Patients with Parkinson's disease who received dopamine agonist therapy, including pramipexole in high doses, reported a pathological craving for gambling, increased libido and hypersexuality, which usually occurred after a dose reduction or discontinuation of treatment.

From the nervous system: often confusion, insomnia, dizziness, impaired consciousness, depression, anxiety; infrequently extrapyramidal syndrome, amnesia, hypoesthesia, dystonia, myoclonus, tremor, ataxia, hypokinesia, delirium, suicidal mood; rarely - malignant neuroleptic syndrome (hyperthermia, muscle rigidity, akathisia, autonomic lability, disturbance of thinking).

From the musculoskeletal system: rarely - hypertension of muscles, leg muscle cramps, muscle twitching, arthritis, bursitis, myasthenia gravis, pain in the lumbosacral spine, pain in the chest, pain in the neck.

From the digestive system: often - decreased appetite, dysphagia, dyspepsia, abdominal pain, flatulence, diarrhea, dry mouth, vomiting.

From the respiratory system: infrequently - pharyngitis, sinusitis, rhinitis, shortness of breath, coughing, voice change; very rarely - flu-like syndrome, pulmonary infiltration, pleural effusion.

From the genitourinary system: rarely - urinary tract infection, frequency of urination.

From the cardiovascular system: often - orthostatic hypotension, infrequently - tachycardia, increased activity of creatine phosphokinase (CK), stenocardia, arrhythmias. In individual patients, lowering blood pressure may occur at the beginning of treatment, especially if the dose of the drug is increased too quickly.

From the sense organs: often - conjunctivitis, paralysis of accommodation, diplopia, cataract, increased intraocular pressure, hearing loss

Other: often - allergic reactions, increased body temperature, weight loss, increased sweating; rarely - retroperitoneal fibrosis. There were cases of development of peripheral edema.

Overdose:

Symptoms: nausea, vomiting, hyperkinesia, hallucinations, excitation and lowering of blood pressure (BP).

Treatment: gastric lavage, symptomatic therapy. There is no specific antidote. The effectiveness of hemodialysis is not established.

Interaction:

Pramipexole to a minor extent (less than 20%) binds to plasma proteins and undergoes biotransformation. Therefore, interactions with other drugs that affect binding to plasma proteins,or excretion due to biotransformation is unlikely.

Selegelin and levodopa do not affect the pharmacokinetics of pramipexole. Pramipeh increases Cmax levodopa by 40% and reduces the time it reaches from 2.5 to 0.5 h.

Drugs that inhibit the active secretion of cationic drugs through the renal tubules (eg, cimetidine), or which are themselves excreted through active secretion through the renal tubules, can interact with pramipexole, which is manifested in a decrease in the clearance of one or both drugs. In the case of simultaneous use of amantadine and pramipexole, it is necessary to pay attention to such signs of dopamine excess stimulation as dyskinesia, excitation or hallucinations. In such cases, it is necessary to reduce the dose.

Diltiazem, triamterene, verapamil, quinidine, quinine, reduce the clearance of pramipexole on 20%.

Interaction with anticholinergic drugs and amantadine has not been studied. However, interaction with amantadine is possible, because drugs have a similar elimination mechanism. Anticholinergic drugs are largely excreted by the metabolic pathway, so interaction with pramipexole is unlikely.

With an increase in the dose of pramipexole, a reduction in the dose of levodopa is recommended, while maintaining the concentration of other antiparkinsonian drugs at a constant level.

Dopamine receptor agonists (derivatives of phenothiazine, butyrofen, thioxanthene, metoclopramide) reduce the effectiveness of pramipexole.

Because of the possible cumulative effects, patients should be advised to exercise caution while using sedatives or ethanol (alcohol) and pramipexole while also taking medications that increase the concentration of pramipexole in plasma (eg, cimetidine).

Special instructions:

Patients with renal insufficiency

Patients with renal failure need a dose adjustment of Pramipexole-Teva (see "Method of administration").

Hallucinations

Hallucinations and confusion are known undesirable effects in the treatment of dopamine receptor agonists and levodopa.

With the simultaneous use of pramipexole-Teva with levodopa in later stages of the disease, hallucinations were more frequent than with monotherapy with Pramipexole-Teva in patients at an early stage of the disease.

Drowsiness

Patients should be warned about a possible sedative effect of Pramipexol-Teva. There were reports of cases of falling asleep during daily activities (including driving), which sometimes led to accidents. In some cases, sleep was not preceded by a state of drowsiness, which is often observed in patients taking Pramipexole-Teva in doses above 1.5 mg per day. A clear relationship between the severity of drowsiness and the duration of treatment was not traced. In most cases (according to available data), after a dose reduction or cessation of treatment, no further episodes of falling asleep were observed.

The risk of orthostatic hypotension

Care should be taken in patients with cardiovascular disease. In connection with the risk of orthostatic hypotension during dopaminergic therapy, it is recommended to monitor blood pressure, especially at the beginning of treatment.

Dyskinesia

When using Pramipexole-Teva in combination with levodopa, in the late stages of Parkinson's disease, at the initial stage of dose selection, dyskinesia may develop, in which case the dose of levodopa should be reduced.

Visual disorders

In case of appearance of visual disturbances, a regular ophthalmological examination is necessary.

Behavior Changes

Patients and caregivers should be warned about possible behavioral changes (increased libido, increased appetite, excessive gambling, etc.), in the event of which it is necessary to reduce the dose of Pramipexol-Teva.

Psychotic disorders

In patients with mental disorders, simultaneous use of antipsychotic drugs with Pramipexol-Teva is possible only if the potential benefit exceeds the possible risk.

Malignant neuroleptic syndrome

It was reported that with a sharp discontinuation of therapy, there was a symptom complex, suggesting a malignant neuroleptic syndrome (see "Method of application").

Effect on the ability to drive transp. cf. and fur:

Care should be taken when taking Pramipexole-Teva because it is possible to develop arterial hypotension, hallucinations and drowsiness, which can affect the ability to drive vehicles and work with potentially dangerous mechanisms.
