      Dopamine Agonists. My be preferred to levodopa because have longer DOA and less likely to cause dyskinesia. Less effective than levodopa as monotherapy. Examples in this category include: Bromocriptine (Parledel) (B) MOA- dopamine receptor agonist at D2 receptor and partial D1 antagonist and ergot alkaloid

      As a centrally active dopamine receptor agonist, it could take the place of levodopa-generated dopamine, and might be a good alternative therapy if the extent of neurodegeneration progresses to where ST can no longer decarboxylate levodopa. Dopamine agonists like ropinirole are sometimes used in combination with levodopa, allowing a lower dose ...

      The important receptor systems and their ligands are listed in Table 2. There are four types of ligand that act by binding to a cell surface receptor, agonists, antagonists, partial agonists, and inverse agonists (Figure 1). (a) Agonists. Ligand s that bind to a receptor and produce an appropriate response are called agonists.

      The best example is risperidone that has ten-fold greater affinity at this receptor than at the dopamine D2 receptor [table 1], so that in clinical practice all 5-HT 2A. receptors are blocked by doses of 5 mg risperidone or above [PET ref]. Other drugs used in psychiatry with

      Clonidine is an agonist, an alpha-2 agonist to be precise. But it acts primarily on noradrenergic autoreceptors thereby decreasing norepinephrine release. Thus clonidine is a direct-acting noradrenergic agonist with indirect-acting antagonist action at other noradrenergic targets.

      An agonist is a compound that binds to the receptor of the molecule it is imitating (dopamine in this case) and causes the normal biological repercussions. In Dilmore’s model, dopamine is actually used to model dopamine’s effects [9]. SKF38393 is a D1 receptor agonist. Thus, it preferentially binds to the D1 receptor.
