Testing the Efficacy of Pharmacological Agents in a Pericardial Target Delivery Model in the Swine
Published on: July 7, 2016
Abstract:
The i.v. administration of amphepramone in dogs induced a dose-related depressor reaction. This effect was due to a peripheral myotropic vasodilatation. When the drug was administered intracerebroventricularly it elicited a marked pressor response, due, to the release of catecholamines with its subsequent action on alpha-adrenergic receptors. Small doses of amphepramone administered in dogs, rats and rabbits, induced a sinus tachycardia. Larger doses brought about a sinus bradycardia, bradyarrhythmias, extrasystoles, ventricular bradycardia and ventricular fibrillation or asystolia. The respiratory movements as well as the EEG tracings were depressed by larger doses of amphepramone.

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
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.
