2. Formoterol (Beta-Agonist)
Formoterol is a long-acting beta-agonist (LABA) that helps to relax the muscles in the airways, improving airflow and reducing symptoms like wheezing and shortness of breath. It is also typically used in powder form or as part of a solution for inhalation.
3. Excipients
Excipients are non-active ingredients used to formulate the medication into an inhalable powder or aerosol. These include:
- Lactose: Used as a carrier for the drug powder in inhalers.
- Stabilizers: To prevent degradation and improve the shelf life of the formulation.
- Propellants: If producing a metered-dose inhaler (MDI), propellants such as hydrofluoroalkane (HFA) are used to deliver the medication.
4. Inhaler Device
The inhaler device is a critical component in delivering the medication. For metered-dose inhalers (MDIs), the device must be carefully manufactured to ensure precise dose delivery and ease of use for patients. Components include:
- Canister: Holds the medication and propellant.
- Valve and Actuator: Controls the release of the drug when the patient inhales.
Machinery and Equipment
