Albuterol is a short acting beta 2 adrenergic agonist. It acts by stimulating the adrenalin (epinephrine) receptors in the bronchial tubes of your lungs which cause the smooth muscle to relax and open up your airways.
The adrenalin receptors in you lungs are primarily beta2 and the receptors in your heart are primarily beta1. Unfortunately, there is still some activity of albuterol on your heart's receptors. When these are stimulated, they can cause a rapid heart rate.
Albuterol can also affect adrenergic receptors elsewhere in your body, including the skeletal muscles and nerves resulting in shaking or tremors.

In general, asthma medication attempts to mimic a sympathetic response >>> bronchodilation by stimulating SPECIFIC receptors, particularly beta 2 adrenergic receptors, because beta 1 receptors would cause an increase in heart rate, which you do not necesarrily want.
Bronchodilation of course opens up the airways, improving O2/CO2 exchange.

I feel your pain. I've had asthma for 14 years now and have seen several doctors. The truth is, there is no known cure for asthma at the moment. But the symptoms can be prevented. It really depends on what causes your brother's asthma. Mine is usually dust and hot weather. But I think the universal method is using the control inhaler.
I cured my Asthma the natural way?
