Abstract:
Twelve normal male volunteers took part in a double-blind placebo-controlled study to measure the effects of d- and l-fenfluramine singly and in combination with d-amphetamine on plasma prolactin levels. Both isomers of fenfluramine were found to differ significantly in their effects from d-amphetamine, and from placebo, causing prolactin levels to rise. d-Fenfluramine produced the greatest change. There were minor differences between the level of activity of the two drugs when given in conjunction with d-amphetamine. d-Amphetamine produced a non-significant reduction in prolactin secretion. The neurochemical basis for the experimental findings reported is considered, with special reference to the use of d-fenfluramine as a specific serotonergic probe.

Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
