Astemizole in perennial allergic rhinitis with seasonal exacerbations: a placebo-controlled double-blind study
1Clinical Immunology and Allergy Unit, Edith Wolfson Medical Center, Holon, Israel.
Abstract:
Astemizole is a nonsedative H1-antagonist. It was used in a randomized double-blind, placebo-controlled in-season trial to assess its efficacy in patients with perennial allergic rhinitis showing seasonal exacerbations. By the last (6th) week of the study, the mean overall symptomatology, as rated by a global composite score, was significantly mitigated in the astemizole-treated group (18 patients) compared with their first week's global composite score (P less than .01). No such improvement was observed in the placebo-treated group (18 patients). Side effects were not appreciable throughout this short-term study. We conclude that astemizole is effective in the treatment of patients with perennial allergic rhinitis showing seasonal enhancement of symptoms.

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...

Antiasthma Drugs: Muscarinic Receptor Antagonists
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
