Parkinson's disease, Parkinson's syndrome.
Dosage and administration
Parkinson's disease, Parkinson's syndrome: amantadine is prescribed in an initial dose of 100 mg daily for the first week, then the dose increases to 100 mg twice a day. The required dose should be established depending on the severity of the symptoms of parkinsonism and tolerability of the drug. A dose greater than 200 mg per day may provide some additional effect, but is associated with an increased risk of toxicity. Do not exceed a dose of 400 mg per day. The daily dose should be increased gradually, at intervals of not less than one week. Since patients older than 65 years, as a rule, have reduced renal function and, therefore, higher concentrations of amantadine in plasma, these patients should be assigned the lowest dose, leading to the desired effect.
Cancellation of amantadine should be carried out gradually, that is, reducing the dose twice at intervals of one week. Abrupt withdrawal of amantadine can exacerbate the symptoms of parkinsonism, regardless of the patient's response to the therapy.
