1 Theophylline is roughly as potent as caffeine; theobromine is seven times weaker than either.

2 Seizures occasionally occur in patients taking theophylline for control of bronchial asthma.

3 Exceptions include phenytoin, theophylline, and heparin.

4 Conclusion: Theophylline transdermal patch has good permeation in vitro.

5 Other bronchodilating agents include theophylline and anticholinergics.

6 The vitro release result which used theophylline as model drug showed, the release behavior can divide to sharp release , relaxedly release and equilibrium release periods.

7 Contain caffeine, theobromine , or theophylline, which can be toxic and affect the heart and nervous system.

8 The preparation of theophylline molecular imprinted polymers ( MIPs ) and its polymerization conditions was expounded.

9 Methods Blood concentration of theophylline was determined by double - wavelength ultraviolet spectrophotometry.

10 The insoluble capsule body, fast - release theophylline tablet and erodible plug were prepared , respectively.

11 Xanthan gum hydrophilic matrix tablets were prepared using theophylline as a model drug.

12 The primary bulk pharmaceuticals produced are: Caffeine, Theophylline, Aminophylline, Metronidazole , Metronidazole benzoate,[] Secnidazaole and Nifedipine.

13 The experts, Yunwu Cha - rich theophylline, tea tannins, vitamins.

14 Theophylline and aminophylline are given by mouth and are less commonly used in Britain because they are more likely to produce side effects than inhaled treatment.

15 Among these hypokalaemia is the most consistent and important finding, and its magnitude correlates well with the concurrent serum theophylline concentration.

16 Any of the methods discussed will easily separate the structurally unrelated compounds nicotine and amphetamine from theophylline. 405.

17 It indicated that it is necessary to make dissolubility test for the theophylline in aminophylline tablets to control the quality.

18 All the samples were investigated with reference to the requirements and the method for Theophylline extended-release capsules in the twenty-third edition of United States Pharmacopoeia.

19 HPLC method was established for determination of theobromine, ephedrine hydrochloride(), theophylline and caffeine in Compound Theophylline and Ephedrine Hydrochloride Tablets.

20 Water, does not contain saccharin, without caffeine, even without theophylline.

21 Theobromine, like caffeine, and also like the asthma drug theophylline, belong to the chemical group known as xanthine alkaloids.

22 To establish a method for determination of formic acid residue in theophylline.

23 AIM : To investigate the effects of low - dose theophylline on differentiation of the naive T lymphocyte.

24 To investigate the mechanism of anti - inflammatory action of theophylline on asthma.

25 Objective: To establish an HPLC method for determination the contents of theophylline, theobromine, ephedrine hydrochloride and caffeine in Compound Theophylline and Ephedrine Tablets.

26 Theophylline is typically used for the treatment of bronchial asthma as a third line of treatment. Aminophylline is a preparation of theophylline used intravenously.
