Abstract:
Salbutamol, a beta-adrenergic agonist, which transiently increases cAMP levels, was tested for its potential adjuvant activity in nasal vaccination. SAG1, the major surface protein of Toxoplasma gondii was used as vaccinating protein to protect CBA mice from a challenge with the parasite. Mice, vaccinated with SAG1 in the presence of salbutamol, showed a highly significant decrease in cerebral cysts, compared to non-vaccinated mice or mice receiving the vaccinating protein alone. Lymph node cells from BALB/c mice, receiving in the footpads a dendritic cell line pulsed with the antigen in the presence of salbutamol, showed a proliferative response in the presence of SAG1. The adjuvant properties of salbutamol are thus partially mediated by its effect on antigen presenting cells.

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: Therapeutic Classification
Vasopressor or pressor agents: They increase blood pressure and function as cardiac stimulants. Examples include endogenous catecholamines (norepinephrine and dopamine) and synthetic agents (phenylephrine).
Bronchodilators: β2-agonists can relax bronchial muscles and widen airways. They are commonly used for treating obstructive pulmonary...
Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
Antiasthma Drugs: β2-Adrenoceptor Agonists
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce relaxation in these...
