Carbidopa is too polar to cross the blood brain barrier and does not inhibit the enzyme in the brain. As a result, L-Dopa is only converted to dopamine in the brain where it is needed. Page reference: 242-243. a. It binds to dopamine receptors in the brain and acts as an agonist. b. It binds to dopamine receptors in the brain and acts as an ...

Dopamine: A Neurotransmitter | Everyday Health
Examples of agonist action are drugs that bind to beta receptors in the heart and increase the force of myocardial contraction or drugs that bind to alpha receptors on blood vessels to increase blood pressure. The binding of the agonist often triggers a series of biochemical events that ultimately leads to the alteration in function.

-this means more L-dopa will reach the CNS Dopamine Agonist Bromocriptine Actions similar to L-Dopa. Potent agonist of D2 receptor. (suppresses prolactin; was used to treat galactorrhoea) Selegiline Indirect agonist. Specifically inhibits MAO-B in the CNS, extending dopamine’s half-life. MAO-B is responsible for the metabolism of dopamine.

Bromocriptine mesylate, a dopamine agonist, is also used to treat NMS. Bromocriptine is given to reverse the hypodopaminergic state and is administered orally (or via nasogastric tube), starting with 2.5 mg given 2 to 3 times daily and increasing doses by 2.5 mg every 24 hours until a response or until reaching a maximum dose of 45 mg/day.
