benserazide profile

Benserazide: An inhibitor of DOPA DECARBOXYLASE that does not enter the central nervous system. It is often given with LEVODOPA in the treatment of parkinsonism to prevent the conversion of levodopa to dopamine in the periphery, thereby increasing the amount that reaches the central nervous system and reducing the required dose. It has no antiparkinson actions when given alone. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

benserazide : A carbohydrazide that results from the formal condensation of the carboxy group of DL-serine with the primary amino group of 4-(hydrazinylmethyl)benzene-1,2,3-triol. An aromatic-L-amino-acid decarboxylase inhibitor (DOPA decarboxylase inhibitor) that does not enter the central nervous system, it is used as its hydrochloride salt as an adjunct to levodopa in the treatment of parkinsonism. By preventing the conversion of levodopa to dopamine in the periphery, it causes an increase in the amount of levodopa reaching the central nervous system and so reduces the required dose. Benserazide has no antiparkinson actions when given alone.

The validated method was applied in a pharmacokinetic study with a levodopa/benserazide tablet formulation in healthy volunteers. Half-life and bioavailability increased approximately 2-fold compared with placebo. Maximum plasma concentration (Cmax) and time to Cmax (tmax) were unaffected.

Bioavailability

Tolcapone had similar effects on plasma levodopa concentrations with the standard-release formulations. Half-life and bioavailability increased approximately 2-fold compared with placebo. In conclusion, the novel COMT inhibitor BIA 3-202 was well tolerated.
