Theophylline - Gyógyszerkereső A kereséshez írja be a keresendő gyógyszer nevét, hatóanyagát, esetleg valamely tulajdonságát! Gyógyszernevek között kere Theophylline is structurally classified as a methylxanthine. It occurs as a white, odorless, crystalline powder with a bitter taste. Anhydrous Theophylline has the chemical name 1 H- Purine -2, 6-dione, 3,7-dihydro-1, 3-dimethyl-, and is represented by the following structural formula: C 7 H 8 N 4 O 2 M.W. 180.17 Theophylline is used to prevent and treat wheezing, shortness of breath, and chest tightness caused by asthma, chronic bronchitis, emphysema, and other lung diseases. It relaxes and opens air passages in the lungs, making it easier to breathe Theophylline in overdose can cause vomiting (which may be severe and intractable), agitation, restlessness, dilated pupils, sinus tachycardia, and hyperglycaemia. More serious effects are haematemesis, convulsions, and supraventricular and ventricular arrhythmias. Severe hypokalaemia may develop rapidly
Theophylline is also thought to increase contraction of the diaphragm muscles. Because of theophylline's similarity in structure to caffeine, it produces a well-known caffeine-like side effect profile such as insomnia, nausea, and headache. Serious adverse effects can occur at higher doses especially in overdoses Theophylline is a widely available medication which may further improve lung function and exercise performance. Previous studies evaluating the effects of theophylline on exercise capacity in.
Theophylline is used in the treatment of reversible airway obstruction due to chronic asthma, chronic bronchitis, or COPD. Both the bronchodilator and the adverse effects are closely related to drug concentration. Theophylline is well absorbed when taken orally as a rapid-release tablet or when administered as a liquid solution Theophylline relaxes the smooth muscle of the bronchial airways and pulmonary blood vessels and reduces airway responsiveness to histamine, methacholine, adenosine, and allergen. Theophylline competitively inhibits type III and type IV phosphodiesterase (PDE), the enzyme responsible for breaking down cyclic AMP in smooth muscle cells, possibly resulting in bronchodilation
Child: Individualise dosing based on serum theophylline levels; use ideal body weight to calculate dose. As theophylline monohydrate modified-release tab: ≥6 years Usual maintenance dose: 9 mg/kg bid. As theophylline (anhydrous) modified-release tab/cap: 6-12 years 20-35 kg: 125-250 mg bid; >12 years Same as adult dose.

Theophylline
In COPD, low-dose theophylline is the first drug to demonstrate clear anti-inflammatory effects, and thus it may even have a role in preventing progression of the disease. Furthermore, the reversal of the steroid resistance induced by oxidative stress suggests that theophylline may increase responsiveness to corticosteroids Theophylline (dimethylxanthine) has been used to treat airway diseases for more than 80 years. It was originally used as a bronchodilator, but the relatively high doses required are associated with frequent side effects, so its use declined as inhaled β2-agonists became more widely used.
