A Study to Assess and Compare Safety and Tolerability of 3 Months Treatment With Salbutamol Administered Via MDI Containing Propellant HFA-152a or HFA-134a in Participants 12 Years of Age and Older With Asthma

This study looks at how safe and easy it is to take a medicine called **salbutamol** for asthma. Asthma makes it hard to breathe because the airways in your lungs get narrow. People who join the study will use a special spray inhaler called a **Metered Dose Inhaler (MDI)**, which helps deliver the medicine directly to your lungs. The study will compare two types of MDI sprays that use different gases (HFA-152a and HFA-134a) to push the medicine out.

• The study lasts for 3 months, and participants must be 12 years or older.
• Participants will have to go for regular check-ups to make sure the treatment is working well for them.
• Participants should not have had severe asthma problems in the last 6 months.

It's important to talk with your doctor before joining, especially if you've had serious asthma issues before or other lung problems. This study helps researchers find the best way to help people with asthma breathe better.
