A Novel Procedure for Evaluating the Reinforcing Properties of Tastants in Laboratory Rats: Operant Intraoral Self-administration
Published on: February 6, 2014
Abstract:
(1) In 1999, all amphetamine derivatives still sold in France as appetite suppressants were withdrawn from the market because of serious cardiovascular adverse effects. Sibutramine, marketed in France since 2001, is closely related to this group of drugs. (2) The adverse effects shared by these drugs are mainly neuropsychiatric (due to a psychostimulant action) and cardiovascular (arterial hypertension and tachycardia). (3) More specific cardiovascular adverse effects, such as pulmonary hypertension and severe cardiac valve damage, emerged after several years of use. The first reports date back to the 1960s. (4) The pulmonary hypertension associated with appetite suppressants can be fatal or necessitate transplantation. (5) Cardiac valve damage due to appetite suppressants is generally irreversible and sometimes requires surgery.

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: 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: 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.
Separation of the aromatic...

Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
