From: An updated calculator for determining levodopa-equivalent dose
Levodopa equivalent dose is calculated according to conversion factors and parameters reported elsewhere by submitting daily doses of commonly used anti-Parkinson drugs (single or in combination) [2, 4, 5]. Immediate-release levodopa 100Â mg 8 times daily is given as an example. Decarboxylase inhibitor in combination with levodopa is understood; difference in bioavailability of levodopa due to presence of benserazide or carbidopa is not considered
