As a member of the xanthine family, it bears structural and pharmacological similarity to caffeine. It is naturally found in tea and in cocoa beans. 1,3-Dimethyl-2,6-dioxo-1,2,3,6-tetrahydropurine 1,3-Dimethyl-3,7-dihydro-1H-purine-2,6-dione 1,3-Dimethyl-3,9-dihydro-1H-purine-2,6-dione 1,3-Dimethyl-7H-purine-2,6-dione 1,3-Dimethylxanthine 1H-Purine-2,6-dione, 3,7-dihydro-1,3-dimethyl- 1H-Purine-2,6-dione, 3,9-dihydro-1,3-dimethyl- 2,6-Dihydroxy-1,3-dimethylpurine 3,7-Dihydro-1,3-dimethyl-1H-purine-2,6-dione, 9CI Accurbron Acet-theocin Aerolate Aerolate III Aerolate sr Aminophylline Aquaphyllin Armophylline Asbron Asmax Austyn Bronkodyl Bronkodyl sr Choledyl sa Constant-t Diphyllin Doraphyllin Duraphyl Dyspne-inhal Elixex Elixicon Elixomin Elixophyllin Elixophyllin sr Elixophylline Euphylline Euphylong Labid Labophylline Lanophyllin Liquophylline Liquorice Maphylline Medaphyllin Mudrane Nuelin Optiphyllin Parkophyllin Pseudotheophylline Purine-2,6(1H,3H)-dione, 1,3-dimethyl- Quibron t/sr Quibron-t Quibron-t/sr Respbid Slo-bid Slo-phyllin Slophyllin Solosin Somophyllin-crt Somophyllin-df Somophyllin-t Spophyllin retard Sustaire Synophylate Synophylate-l.a. cenules T-phyl Tefamin Teofilina Teofyllamin Teolair Teonova Theacitin Theal tabl.
