The most common adverse effects are gastric irritation, nausea, vomiting, diarrhea, hematemesis, epigastric pain and tremor. These are usually early signs of toxicity; however, with high doses, ventricular arrhythmias or seizures may be the first signs to appear and reactivation of peptic ulcer, headache, irritability, restlessness, insomnia, twitching, convulsion and reflex hyperexcitability, palpitation, tachycardia, hypotension, circulatory failure, ventricular arrhythmias, and flushing, albuminuria, diuresis and hematuria. Also inappropriate ADH syndrome may occur.
Aminophylline is a combination of theophylline and ethylenediamine. Ethylenediamine is inactive; it increases the solubility of theophylline in water. Theophylline relaxes bronchial smooth muscle. Suggested mechanisms are an increase in intracellular cAMP through inhibition of phosphodiesterase; adenosine receptor antagonism, prostaglandin antagonism and effects on intracellular calcium.
Aminophylline should be given with caution to patients with peptic ulceration, hyperthyroidism, hypertension, cardiac arrhythmias or other cardiovascular disease, or epilepsy, as these conditions may be exacerbated. They should also be given withcaution to patients with heart failure, hepatic dysfunction, chronic alcoholism, acute febrile illness, and to neonates and the elderly, since in all of these circumstances theophylline clearance may be decreased, resulting in increases in serum-theophylline concentrations and serum half-life.
Use of aminophylline in pregnant women should be balanced against the risk of uncontrolled disease.
Aminophylline should not be administered to patients with hypersensitivity to xanthines or ehylenediamine. It should not be administered to patients with active peptic ulcer, since it may increase the volume and acidity of gastric secretions.
