Benefits of a new galenic form of levodopa and benserazide in the treatment of patients with Parkinson disease

: We describe a new, water-soluble formulation of levodopa plus benserazide (Madopar LIQ) for the treatment of Parkinson's disease. Two dosage strengths are available: 100 mg levodopa plus 25 mg benserazide and 50 mg levodopa plus 12.5 mg benserazide. Pharmacokinetic data show that levodopa absorption is more rapid than with standard Madopar, resulting in a shorter time to peak plasma concentration. Other pharmacokinetic values are comparable to those obtained with the standard formulation. We discuss the clinical advantages of this new water-soluble formulation, particularly when the patient requires rapid onset of action for morning or circadian akinesia. The indications of this formulation in patients with dysphagia and in other clinical situations, e.g. during the postoperative period and for levodopa dosage adjustment in ambulatory care, are discussed.
