Description

Salbutamol Sulfate CAS NO 39971-61-4 is a selective β2-adrenergic receptor agonist widely recognized for its bronchodilatory effects. This active pharmaceutical ingredient (API) is critical for the formulation of respiratory medications that provide rapid relief from bronchospasm. It is essential for pharmaceutical manufacturers developing treatments for asthma, chronic obstructive pulmonary disease (COPD), and other respiratory conditions requiring immediate symptom management.

Application

• Primary Pharmaceutical API: Core active ingredient in metered-dose inhalers (MDIs), dry powder inhalers (DPIs), and nebulizer solutions for asthma and COPD.
• Tablet and Syrup Formulations: Used in oral dosage forms for the management and prevention of exercise-induced bronchoconstriction.
• Veterinary Medicine: Employed in veterinary practice for the treatment of bronchoconstrictive conditions in animals.
• Research and Development: Serves as a key reference standard and building block in pharmacological research for new respiratory therapeutics.
• Compounding Pharmacy: Utilized by specialized pharmacies for preparing customized medication formulations for patients with specific needs.
