Theophylline (Aminophylline, Deriphyllin, Theolong, Theomac)
This is a frequently prescribed bronchodilator to relieve and prevent symptoms of asthma, chronic bronchitis, and emphysema. In smokers, the drug is more rapidly eliminated from the body than in non-smokers, and thus its level in the blood decreases faster, reducing the duration of action.
Some heavy smokers may require as much as one and a half to two time the maintenance dose of theophylline. It may take six months to three years to return to normal after smoking is stopped.
Propranolol (Inderal Corbeta), Metoprolol (Metolar, Betaloc)
