I live in the US and use carbidopa/levodopa and am familiar with it's dosing protocols. My mother in law lives in El Salvador and takes Prolopa which is levodopa and benserazide (instead of carbidopa). I understand that Prolopa and Madopar are essentially the same.
We just visited my mother in law and I was surprised that she is on Prolopa 250/50 twice a day. I know that standard dosing of C/L calls for three times a day, and more recently doctors are also using four times a day, as this may work better to achieve a steady state.
I'm wondering if the dosing difference is due to a difference between carbidopa and benzeraside, or if it's a difference in what is customarily prescribed in different countries?
