[Description]

Budesonide (brand name: Pulmicort) is a synthetic corticosteroid medication. It is indicated for the maintenance and prophylactic treatment of asthma. It is also used for the long-term management of chronic obstructive pulmonary disease (COPD). It is also useful for the treatment of inflammatory bowel disease including Crohn’s disease, ulcerative colitis and microscopic colitis, and also for treating allergic rhinitis. It exhibits potent glucocorticoid activity and weak mineralocorticoid activity in vivo. It is effective in inhibiting the activities of multiple cell types and mediators participating in either allergic or non-allergic-mediated inflammation.
[indications]

Budesonide is a commonly used in the treatment of bronchial asthma clinical drug in China.it can be used for non-hormone-dependent or hormone-dependent asthma, and chronic asthmatic bronchitis. Or it is used for the treatment of seasonal allergic rhinitis and many years occurring allergic rhinitis and it is used for preventing polyps regeneration after the removal of nasal polyps . It can also be used to treat various skin diseases.
Budesonide is a halogen-free, topically applied , adrenal corticosteroid,it has significant anti-inflammatory, anti-allergic, anti-itching and anti-exudative effects. Its local effects is the same as beclomethasone dipropionate , it is mainly used for bronchial asthma which in the past bronchodilator or an antiallergic agent can not well control. This product can relieve bronchial spasm, pulmonary inhalation has anti-inflammatory effects, long-term use is well tolerated, it can reduce oral glucocorticoid dosage, without systemic effects of corticosteroids. It has the same effect on Children and adults with asthma as beclomethasone dipropionate , it has good effect, and it can be tolerated in long-term use ,for glucocorticoid-dependent or glucocorticoid-independent patients, mist inhaled can control asthma attacks and can effectively relapse prevention, inhaled treatment for 3 to 6 months, improvement in lung function is shown,the number of acute episodes is reduced , recoverability of plasma corticosterone concentration is gradually increased, and the daily dose of oral corticosteroids can be reduced by 40% to 50%. Thus,for glucocorticoid-dependent asthma patients, especially in patients with a larger amount of dose,the product can be used as an ideal alternative to thedrug for oral administration. Glucocorticoid effects of budesonide are strong, but mineralocorticoid effects are weak . Animal tests show that the drug’s effects on glucocorticoid receptor affinity are 200 times of cortisone, anti-inflammatory effects when it is applied topically are 1,000 times of cortisone , and subcutaneous and oral anti-inflammatory effects are only 40 and 25 times stronger than cortisone .
[Precaution and Inhibition]

Take Caution when it is used in tuberculosis, airway fungal infection or viral infection. Avoid pregnancy administration. Oral steroid-dependent patients, should gradually reduce oral steroid dose after 10d use , until it reaches a stable respiratory capacity minimum. In severe stress, the dose of oral steroids should be increased, such as severe infection, trauma, surgery. When sputum thickens and congests the airway , the short-term oral steroid should be supplemented . Fast Reduction of Oral hormone, can cause withdrawal symptoms, such as arthritis, rhinitis, eczema, muscle and joint pain,which should be paid attention to prevent it.
Budesonide can be used for mild asthma, when asthma symptoms are obvious,they should be added with a larger dose of water-soluble corticosteroids or bronchodilators and antihistamines. Aerosol has throat irritation on individual patient , Candida albicans infections may occur , rinse mouth and throat immediately after inhalation which can reduce irritation.
