Description

Formoterol is a highly selective long-acting beta2-adrenergic receptor agonist (LABA) used as a bronchodilator. It is valued for its rapid onset and prolonged duration of action, making it a cornerstone in the management of obstructive airway diseases. This active pharmaceutical ingredient (API) is essential for manufacturers developing inhalation therapies, such as dry powder inhalers (DPIs) and metered-dose inhalers (MDIs), for conditions like asthma and chronic obstructive pulmonary disease (COPD).

Application

• Primary Active Pharmaceutical Ingredient (API) in dry powder inhalers (DPIs) for asthma control.
• Key component in pressurized metered-dose inhalers (pMDIs) for the treatment of COPD.
• Used in combination inhaler formulations with corticosteroids (e.g., budesonide/formoterol) for enhanced therapeutic effect.
• Critical material in pharmaceutical R&D for developing novel respiratory drug delivery systems.
• Reference standard in analytical laboratories for quality control and method validation.
• Used in clinical research studies investigating long-acting bronchodilator therapies.

Quality Control

Our Formoterol is manufactured under strict quality management systems. Each batch is tested to meet high-purity pharmacopeial standards, including identification, assay, and control of specified impurities and residual solvents. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing results against specifications for identity, purity, and strength.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to maintain stability and potency.
