Video Summary:
Pathophysiology of Parkinson’s disease was covered in first video. Antiparkinsonian drugs are levodopa, peripheral dopa decarboxylase inhibitors like carbidopa and benserazide, COMT inhibitors like tolcapone and entacapone, amantadine, dopamine receptor agonists like bromocriptine, pergolide, ropinirole and pramipexole, MAO-B inhibitors like selegiline and rasagiline and centrally acting antimuscarinic agents.
Levodopa is precursor of dopamine. So, when given to patients of Parkinson’s disease, remaining healthy neurons synthesize more dopamine from levodopa. This increases dopamine activity in brain and thus relieves symptoms. However, most of the levodopa is lost due to its peripheral conversion into dopamine by peripheral dopa decarboxylase and degradation by catechol o methyl transferase. To limit this loss DDC inhibitors like carbidopa and benserazide, and COMT inhibitors like tolcapone and entacapone can be used.
