Any good tablet for permanent Asthma Patient? and any good suggestion to reduce stomach for me?

I am an ASTHMA (a breath trouble or Decease) patient. I takes a tablet every night named ETO SALBETOL. (FORMULA: Etotylline + Salbutamol + bromhexine Tablets). I got too much shivering and extra faster heartbeats after taking this tablet. this shivering go continue for 4-5 hours then i get regular blood pressure, no shivering & normal heartbeats. My age is 23 but i am shivering like 90 year old man after taking this tablet, but there is no other option to kill the attack of this breath trouble. and because of asthma, i cant do any hard work, long walk or outdoor games. so my waist is 28 and my stomach is 34!!! :( very bad looking my figure is! give me another good tablet or Formula for asthma which would not give me side effects like shivering and give me a sure and safe way to reduce my stomach less that my chest. (well, i got this trouble in Heredity.) Thank you to all of you readers in advance, God bless you.
