**Study on Asthma Treatment** This study tests a new asthma medicine for people aged 12 and older. Asthma is a condition that makes it hard to breathe. The medicine combines two drugs: **fluticasone propionate** and **albuterol sulfate**. These drugs are taken using a special inhaler that helps you breathe them in. This study will last about 10 weeks, but you can have a visit before starting the study to see if you're a good fit. - **Key Points:** - You will need to use the inhaler four times a day for four weeks. - The study will check how safe and effective the medicine is. - You can't join if you've had certain health problems like severe asthma attacks or if you smoke. **To Join:** You need to have had asthma for at least 6 months and be using certain asthma medicines already. If you're a girl, you cannot be pregnant or trying to get pregnant. Some conditions will keep you from joining, like recent lung infections or smoking.
