Budesonide is often used as an inhaler medication prescribed for the maintenance treatment of asthmatic patients. It belongs to a class of drugs called corticosteroids.
The drug is used to control symptoms of asthma such as shortness of breath, difficulty breathing, or wheezing. It is often not used alone to treat asthma. Budesonide is a glucocorticoid, which has anti inflammatory action that reduces the inflammation and spasms of the air passage that are caused by asthma. The anti inflammatory action is due to the reduced cytokines of the mast cells and lymphocytes. It also reduces the quantity and viscosity of the secreted mucus during an allergic reaction that blocks the airway. Once inhaled, it travels from the mouth to the lungs and relaxes the lungs as well as the airways to ease the breathing process.
Dosage and administration
Budesonide is available as rotacaps in doses of 100 mcg, 200 mcg, and 400 mcg. The rotacaps must be used with a rotahaler. The rotacaps should not be swallowed. The prescribed dose may vary depending on the individual’s age, sex, and weight. Always follow the doctor’s instructions and read the directions stated on the prescription label.
The initial prescribed dose is 400 mcg per day in 2 divided doses, which can gradually be increased up to 1.6 mg per day if the case is severe.
The usual maintenance dose is 200-400 mcg/day. In case you miss a regular dose of the drug, do not take two doses at once. Just go for the next dose.
