A popular bronchodilator that is intended to offer prompt relief from asthma and other respiratory disorders like chronic obstructive pulmonary disease (COPD) is the Asthalin 100 mcg inhaler.  During instances of wheezing, shortness of breath, or tightness in the chest, it contains salbutamol, a fast-acting drug that helps relax the muscles in the airways.  This inhaler is commonly used as a "rescue inhaler" to treat acute asthma symptoms or avoid exercise-induced bronchospasm. It delivers 100 microgrammes of salbutamol every puff.  For those who need quick relief from respiratory distress, the Asthalin 100 mcg inhaler is indispensable. It starts working in a matter of minutes.  Although it works well for controlling symptoms temporarily, it should not be used in place of long-term controller drugs and should only be used under a doctor's supervision.
