Ventolin is a brand product that contains Salbutamol, which is a type of bronchodilator. It works by relaxing the muscles in the throat to open up the airways for easier breathing.
It is used to relieve acute symptoms (e.g. shortness of breath, wheezing) that occurs in asthma and COPD.
Ventolin is used as an metered-dose inhaler (MDI), dry powder inhaler (DPI, e.g. accuhaler) or nebulizer, but each inhaler works in a slightly different way. Intravenous infusion is used only in severe conditions under the direction of a physician.
Listed below are the usual dosages for adults, whereas the doses for children vary with their ages and the intentions for uses. Consult your doctor or pharmacist for details.
Inhalation of aerosol (MDI or DPI)
100-200 mcg (2 puffs for MDI / 1 puff for DPI) for acute relief. Inhalation can be repeated every 4-6 hours as needed. To prevent exercise-induced bronchospasm, you can use 15-30 minutes before exercise.
