(1) Anyone have the experience in taking comtan & levodopa together? I take comtan 100mg & levodopa(sinemet) 50mg after each meal. There are two statements about above doses : (a) the comtan may enhance the levodopa dose from 50mg to 75mg(enhance 50% entering the brain). (b) the comtan,as the inhibitor role, may extend the levodopa active state 25%,ex. from 2hrs to 2.5hrs. I not assure which one is correct ? or,both correct ? (2) What is the purpose about Selegiline ? What is it good to PD patient ?
