Theophyllines work differently to beta-agonists and are often used in combination with them to provide an added benefit. Similar to beta-agonists, they also help relieve bronchial spasms and clear excessive mucus from the lungs. Theophyllines cannot be administered as sprays. The range of theophylline drugs includes standard formulations and sustained-release preparations. Some commonly used types of theophylline drugs are Brondecon, Quibron, Elexophyllin, Cardophyllin, Choledyl, Nuelin and Somophyllin. These drugs start taking effect within about 20 minutes of being administered and their effects normally last for approximately four hours.
Sustained-release theophyllines are specially formulated capsules or tablets that are absorbed very slowly into the system. They ate designed to maintain therapeutic levels of medication over a long period — about ten to 12 hours. They are not to be used in the event of an acute attack as they take too long to become effective. Some of the commonly prescribed sustained-release theophylline drugs are Nuelin SR, Nuelin sprinkle capsules, Theo-Dur, Somophyllin CRT and Austyn.
SIDE EFFECTS OF THEOPHYLLINES
Theophyllines can produce a number of discomforting side effects. The most common are nausea, vomiting and a bitter taste in the mouth. Occasional side effects include headaches and upset stomachs. In children, theophyllines often cause hyperactivity, sleeplessness and nightmares; sometimes personality changes occur. If you or your child experience side effects from taking a normal dose, the medication may have to be reduced or gradually built up over a period of time.
