CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY vs PERIACTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fexofenadine is a selective peripheral H1-receptor antagonist. It inhibits histamine release from mast cells and basophils, reducing allergic symptoms.
Cyproheptadine is a first-generation antihistamine with anticholinergic and antiserotonergic properties. It acts as a competitive antagonist at histamine H1 receptors and serotonin 5-HT2 receptors, thereby inhibiting histamine-mediated allergic symptoms and serotonin-mediated effects such as increased gastrointestinal motility and vascular permeability.
Fexofenadine hydrochloride 60 mg orally twice daily or 180 mg orally once daily.
4 mg orally three times daily; adjust as needed. Maximum: 32 mg/day.
