Beclometasone is a synthetic corticosteroid with potent anti-inflammatory properties, commonly used as an inhaled treatment for asthma and allergic rhinitis. It acts by reducing airway inflammation and bronchial hyperresponsiveness. Beclometasone is approved and widely used in current clinical practice.
Pharmacokinetics
Pharmacokinetic data reported for healthy adult volunteers (both sexes) after inhalation administration.
