Title: Phase III: The Study of Acid Reflux in Children With Asthma
Brief Summary: Many individuals with asthma also experience gastroesophageal reflux disease (GERD), a condition in which excess stomach acid flows backwards into the esophagus. This study will evaluate the effectiveness of lansoprazole, a medication commonly used to treat GERD in improving asthma control and reducing symptoms in children with poorly controlled asthma.

All patients including the patients under age (under 20 years old) must sign and date an Informed Consent Form consistent with ICH-GCP guidelines and Good Clinical Practice (GCP) prior to participation in the trial \[i.e. prior to any trial procedures, including any pre-trial washout of medications and medication restrictions for pulmonary function test (PFT) at Visit 1\]. Regarding patients under age, a guardian or a legally authorised representative must also sign and date an Informed Consent Form.

4. The initial diagnosis of asthma must have been made before the patient's age of 40.
5. The diagnosis of asthma has to be confirmed at Visit 1 with a bronchodilator reversibility (15-30 minutes after 400 µg salbutamol) resulting in a Forced Expiratory Volume in one second (FEV1) increase of at least 12% and at least 200 mL .
