ব্যবহার

Rasagiline tablet is indicated as monotherapy or as adjunct therapy for the treatment of Parkinson's disease (PD).

ফার্মাকোলজি

Rasagiline is an irreversible inhibitor of monoamine oxidase and is used as a monotherapy in early Parkinson's disease or as an adjunct therapy in more advanced cases. The way it acts is related to its MAO-B inhibitory activity, which causes an increase in extracellular levels of dopamine in the striatum. The elevated dopamine level and subsequent increased dopaminergic activity are likely to mediate rasagiline's beneficial effects seen in models of dopaminergic motor dysfunction.

সেবনবিধি

The recommended dose is 1 mg orally once daily as monotherapy or as adjunct therapy in patients not taking levodopa. In patients taking levodopa, with or without other PD drugs (e.g., dopamine agonist, amantadine, anticholinergics), the recommended initial dose of Rasagiline is 0.5 mg once daily. If the patient tolerates the daily 0.5 mg dose, but a sufficient clinical response is not achieved, the dose may be increased to 1 mg once daily. When Rasagiline is used in combination with levodopa, a reduction of the levodopa dose may be considered, based upon individual response. The recommended dose of Rasagiline should not be exceeded because of risk of hypertension.Pediatric use: The safety & effectiveness in pediatric patients have not been established.Geriatric use: There were no significant differences in the safety profile of the geriatric & nongeriatric patients.

সতর্কতা

Hypertension: Exacerbation of hypertension may occur during treatment with Rasagiline. Medication adjustment may be necessary if elevation of blood pressure is sustained. Dietary tyramine restriction is not required during treatment with recommended doses of Rasagiline. However, certain foods that may contain very high amounts (more than 150 mg) of tyramine that could potentially cause severe hypertension because of tyramine interaction in patients taking Rasagiline, even at the recommended doses, due to increased sensitivity to tyramine. In that case, patients should be advised to avoid foods containing a very large amount of tyramine.Serotonin Syndrome: Serotonin syndrome has been reported with concomitant use of an antidepressant (e.g., SSRIs, SNRIs, tricyclic & tetracyclic antidepressants, Triazolopyridine antidepressants) and a nonselective MAOI (e.g., phenelzine, tranylcypromine) or selective MAO-B inhibitors, such as Rasagiline.Ciprofloxacin or other CYP1A2 Inhibitors: Patients taking concomitant ciprofloxacin or other CYP1A2 inhibitors should not exceed a dose of Rasagiline 0.5 mg once daily.Hepatic impairment: Patients with mild hepatic impairment should be given the dose of Rasagiline 0.5 mg once daily. Rasagiline should not be used in patients with moderate or severe hepatic impairment.The concomitant use of Rasagiline and fluoxetine or fluvoxamine should be avoided. At least five weeks shouldelapse between discontinuation of fluoxetine and initiation of treatment with Rasagiline. At least 14 days should elapse between discontinuation of Rasagiline and initiation of treatment with fluoxetine or fluvoxamine.The concomitant use of Rasagiline and dextromethorphan or sympathomimetics such as, those present in nasal and oral decongestants or cold medicinal product containing ephedrine or pseudoephedrine is not recommended.During the clinical development program the occurrence of cases of melanoma prompted the consideration of a possible association with Rasagiline. The data collected suggests that Parkinson's disease and not any medicinal products in particular, is associated with a higher risk of skin cancer (not exclusively melanoma). Any suspicious skin lesion should be evaluated by a specialist.

Pregnancy category C. Caution should be exercised when prescribing to pregnant women. Experimental data indicated that Rasagiline inhibits prolactin secretion and, thus, may inhibit lactation. It is not known whether Rasagiline is excreted in human milk. Caution should be exercised when Rasagiline is administered to a breastfeeding mother.

Signs and symptoms of Rasagiline overdose may include drowsiness, dizziness, faintness, irritability, hyperactivity, agitation, severe headache, hallucinations, trismus, opisthotonos, convulsions and coma; rapid and irregular pulse, hypertension, hypotension and vascular collapse; precordial pain, respiratory depression and failure, hyperpyrexia, diaphoresis, and cool, clammy skin.Treatment: There is no specific antidote for Rasagiline overdose. The following suggestions are offered: Respiration should be supported by appropriate measures, including management of the airway, use of supplemental oxygen, and mechanical ventilator assistance, as required. Body temperature should be monitored closely. Intensive management of hyperpyrexia may be required. Maintenance of fluid and electrolyte imbalance is essential. For this reason, in cases of overdose with Rasagiline, dietary tyramine restriction should be observed for several weeks to reduce the risk of hypertensive tyramine reaction. Moreover, a poison control center should be called for the most current treatment guidelines.
