As mentioned above, the 5-HT 1 B/D agonist sumatriptan, 5-HT 2A antagonists, and the 5-HT 3 receptor antagonist tropisetron have been shown to reduce pain behavior in certain animal models. Furthermore, a state-dependent … An adrenergic agonist is a drug that stimulates a response from the adrenergic receptors. The five main categories of adrenergic receptors are: α1, α2, β1, β2, and β3, although there are more subtypes, and agonists vary in specificity between these receptors, and may be classified respectively. However, there are also other mechanisms of adrenergic agonism. Epinephrine and norepinephrine are endogenous and broad-spectrum. More selective agonists are more useful in …
