简要总结
National clinical trial, phase III, multicenter, single-arm, efficacy study, 80 participants of both sexes, aged equal or more than 12 and less than 65 years. The group will use Busonid® (budesonide 200mcg and 400mcg) one application (inhalation) of 200 mcg every 12 hours (400mcg / day). During follow-up visits if the participant has not shown an increase in forced expiratory volume in one second greater than 12% and greater than 0,20L or 200ml in spirometry compared with baseline visit, will increase the dose to 800 mcg / day (2x 400 mcg day).
The study aims to revalidate by the National Health Surveillance Agency (ANVISA) the registration of the drug Busonid® which there is a vast scientific literature on the pre-clinical and clinical evidence that the efficacy and safety of budesonide. Thus, outlined is a single-arm study, which is applied to the study of the group of participants the same intervention for a certain period and the participants are evaluated for response.
详细描述
Busonid® is composed of budesonide and has two performances of 200mcg and 400mcg. It is a corticosteroid hormone with topical anti-inflammatory activity. The slow and continuous release of budesonide in the airways due to their esterification and their short plasma half life increases the selectivity of the corticosteroid to the airways, in patients with asthma, inhaled corticosteroids have a broad spectrum of anti-inflammatory effects, such as reducing the number of inflammatory cells in the lungs and inhibiting the synthesis and release of cytokines and other inflammatory mediators.

研究组 & 干预措施
Busonid (budesonide 200mcg and 400mcg)
It´s a capsule with inhalatoin powder composed of budesonide 200mcg or 400mcg. The experimental drug will be dispensed in a cartridge containing 60 capsules of 200 mcg or 400 mcg and an inhaler. It should be stored at room temperature (between 15 and 30°C) and protected from moisture.
Regarding the dosage, the 80 study participants will perform an inhalation 200mcg every 12 hours (400 mcg / day). During follow-up visits (V1 and V2) the attending physician will assess the need for increased PSI dose to 400 mcg every 12 hours (800mcg / day). Study participants should rinse the mouth with water and / or brush your teeth immediately after use of the drug.
The duration of treatment may be 12 weeks.

结局指标
主要结局
Efficacy of Busonid® (budesonide 200 mcg and 400 mcg) in the treatment of asthma after the initiation of treatment (FEV1)
时间窗: 12 weeks
The absolute change in forced expiratory volume in one second \[FEV1 (L)\], 12 weeks after start of treatment (VF) compared to baseline (V0) was measured by spirometry test.
