Feedback:
Antihistamines are H1-receptor antagonists. Medications in the classification of H2-receptor antagonists (e.g., cimetidine, ranitidine) are used to treat gastric and duodenal ulcers. Leukotrienes are chemical mediators that are 1001,000 times more potent than histamine in causing bronchospasm. Clients may receive epinephrine in emergencies to neutralize the adverse effects of histamine.
