    Pharmacotherapeutic group:antiparkinsonian means - MAO inhibitor
    ATX: & nbsp

    N.04.B.D   Inhibitors of monoamine oxidase type B

    N.04.B.D.02   Razagilin

    Pharmacodynamics:

    Razagilin is selective irreversible inhibitor of monoamine oxidase type B (MAO-B), an enzyme that determines the activity of monoamine oxidase in the brain and the metabolism of dopamine by 80%. He is 30-80 times more active against MAO-B than to another type of this enzyme - MAO-A. As a result of the inhibitory effect of the drug on MAO-B in the central nervous system, the level of dopamine increases, the formation of toxic free radicals, excessive formation of which is observed in patients with Parkinson's disease, decreases. Razagilin has also a neuroprotective effect.

    Unlike indiscriminate MAO inhibitors, the drug in therapeutic doses does not block the metabolism of biogenic amines coming from food (for example, tyramine), and therefore does not cause a tyramine-mediated hypertensive syndrome ("cheese effect").

    Pharmacokinetics:

    Rasagiline is rapidly absorbed after oral administration; its maximum concentration in the blood plasma (Сmах) is achieved after 0.5 hours. Absolute bioavailability of the drug after a single administration is about 36 %. Food does not affect the time to reach the maximum concentration of rasagiline in the blood, however, when consuming fatty foods Сmах and the area under the drug concentration curve (AUC) are reduced by 60% and 20%, respectively. Pharmacokinetics of the drug is linear in the dose range of 0.5-2 mg. The connection with plasma proteins varies from 60 to 70%. Razagilin almost completely metabolized in the liver. Biotransformation is carried out by Ndealkylation and / or hydroxylation to form the main biologically inactive metabolite - 1-aminoindane, as well as 2 other metabolites of 3-hydroxy-M-propargyl-1 aminoindane and 3-hydroxy-1-aminoindane.The drug is metabolized with isoform CYP 1A2 of the cytochrome P-450 system. Razagilin is excreted mainly by the kidneys (more than 60%) and to a lesser extent through the intestine (more than 20%). Less than 1% of the administered dose of the drug is released unchanged. The half-life is 0.6-2 hours. The parameters of pharmacokinetics of rasagiline practically do not change in patients with mild and moderate renal insufficiency. With mild hepatic insufficiency, there may be an increase in the values ​​of the parameters AUC and Сmах by 80% and 38%, and in patients with moderate impairment of liver function these parameters reach more than 500% and 80%, respectively.

    Indications:

    Monotherapy or combination therapy of Parkinson's disease (with levodopa preparations).


    Contraindications:
    • hypersensitivity to rasagiline or any of the components of the drug;

    • concomitant therapy with pethidine or other MAO inhibitors, fluoxetine and fluvoxamine. The break between the cancellation of rasagiline and the initiation of therapy with these drugs should be at least 14 days;

    • moderate or severe hepatic impairment (Child-Pugh);

    • joint therapy with decongestants, sympathomimetics (including those containing them), dextromethorphan.

    Carefully:

    Mild form of hepatic insufficiency; joint administration with selective serotonin reuptake inhibitors, tricyclic and tetracyclic antidepressants, active inhibitors of CYP1A2

    Pregnancy and lactation:


    Dosing and Administration:

    Razagilin is administered orally at a dose of 1 mg once a day, both in monotherapy and in the presence of levodopa, for a long time. The intake of the drug is not dependent on food intake.

    Side effects:

    From the side of the musculoskeletal and connective tissue:

    According to the post-experience experience, these symptoms were noted in patients with Parkinson's disease,

    who received rasagiline.

    About serious undesirable reactions arising at simultaneous these symptoms were noted in patients with Parkinson's disease,

    who received rasagiline.

    About serious undesirable reactions arising at simultaneous

    application of SSRIs, SSRIs,

    tricyclic / tetracyclic antidepressants and MAO inhibitors are well known.In the post-marketing period, cases of the development of serotonin syndrome, manifested in agitation, confusion,

    rigidity, fever, and myoclonus, in patients concomitantly taking antidepressants / SSRIs and rasagiline.

    In clinical studies of rasagiline, the simultaneous use of it with fluoxetine or fluvoxamine was not allowed. However, the following antidepressants were allowed in these doses: amitriptyline not more than 50 mg / day, trazodone not more than 100 mg / day, citalopram not more than 20 mg / day, sertraline not more than 100 mg / day and paroxetine not more than 30 mg / day. In a clinical research program in which rasagiline simultaneously applied with tricyclic

    antidepressants (115 patients) and SSRIs / SSRIs (141 patients), cases of serotonin syndrome were not observed. When rasagiline was used during the postgistribution period, it was reported that blood pressure (BP) increased, including rare cases of hypertensive crises, in patients using an undefined diet in the diet

    number of products rich in tyramine. There are cases of drug

    interaction with the simultaneous use of MAO inhibitors with sympathomimetic drug preparations.

    Overdose:

    Symptoms of drug overdose are similar to those in overdose with indiscriminate MAO inhibitors (arterial hypertension, postural hypotension, etc.).

    Treatment: There is no specific antidote. Gastric lavage, reception of activated charcoal, symptomatic therapy.

    Interaction:

    Due to the fact that the mechanism of action of rasagiline is associated with MAO inhibition, as in the case of other drugs of a similar mechanism of action, it can not be administered simultaneously with other inhibitors of this enzyme because of the risk of developing a hypertensive crisis. Combined use of rasagiline with medications should be avoided, the mechanism of action of which includes inhibition of reverse neuronal seizure of serotonin (fluoxetine, fluvoxamine and others), tricyclic and tetracyclic

    antidepressants, MAO inhibitors, as it is possible to develop a "serotonergic syndrome" manifested in confusion, hypomania, motor anxiety, chills, tremor,diarrhea. If necessary, use by patients receiving rasagiline, similar drugs - they are used with caution.

    It is also not recommended that the combined use of rasagiline with sympathomimetic drugs, including ephedrine, pseudoephedrine, contained in preparations for the treatment of rhinitis or colds (decongestants). In addition, the use of rasagiline with analgesic / antitussive drug dextromethorphan and its combined agents is not recommended.

    Due to the fact that the isoform of the cytochrome P450 1A2 enzyme (CYP1A2) participates in the metabolism of rasagiline, the active inhibitors of this enzyme (for example, ciprofloxacin) can increase the concentration of the drug in the blood plasma, which determines caution when combining such drugs with rasagiline.

    In patients with Parkinson's disease, the use of levodopa drugs does not affect the clearance of rasagiline.

    Special instructions:

    The use of Azilec in the recommended therapeutic dose does not cause a "tyramine syndrome" ("cheese effect"), which allows patients without restrictions to use in food products,containing significant amounts of tyramine (cheeses, chocolate and DR -) -

    There is evidence that Parkinson's disease, rather than the use of any were observed in the post-marketing period in patients taking Azilect (see "Side effect" section). It is necessary to observe patients, in connection with the possibility of developing an impulsive personality disorder. Patients and carers should be informed of the possibility of developing behavioral disorders in patients taking Azilekt, including compulsive behavior, obsessions, gambling, increased libido, hypersexuality.

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

    Influence on the ability to drive vehicles and work with techniques that require increased concentration of attention

    The study of the influence of rasagiline on driving and control of other mechanisms was not carried out.

    However, given the possibility of significant side effects from the central nervous system, during the period treatment with Azilekt

    impulsive behavior and compulsive needs to buy or acquire.Simultaneous use of the drug Azilekt with dextromethorphan, with sympathomimetics or complex anti-cold medications for oral or nasal use, containing ephedrine or pseudoephedrine, is not recommended (see section "Interaction with other medicinal products").

    There is evidence that Parkinson's disease, and not the use of any drug, including Azilekt, is a risk factor for the development of skin cancer, in particular melanoma (see section "Side effect"). It is necessary to warn the patient about the need to consult a doctor if any pathological changes in the skin occur. It should be borne in mind that such symptoms as hallucinations and confusion that appear on the background of Azilect treatment can be considered both as a manifestation of Parkinson's disease and as undesirable reactions of Azilect (see "Side ("Pharmacokinetics")).

    Impact on the ability to manage vehicles and mechanisms

    The study of the influence of rasagiline on the ability to control vehicles and mechanisms was not carried out.

    However, given the possibility of significant side effects from the central nervous system, during the treatment with the drug Azilect follows andInform patients about the need to be cautious when driving vehicles and engage in potentially dangerous activities that require a high concentration of attention and speed of psychomotor reactions until they make sure that the drug does not have a negative effect.
