| | 8-Bromotheophylline Usage And Synthesis |
| Description | Bromotheophylline is the active moiety of pamabrom, a mixture of 2-amino-2-methyl-propanol and bromotheophylline. From this mixture, bromotheophylline acts as a weak diuretic that has been used along with some analgesics to relieve the symptoms of premenstrual syndrome. Bromotheophylline is categorized on the FDA as a drug substance with an inactive state since March, 1980. It is also approved by Health Canada to be used alone or in combination with [DB00316] in OTC products. | | Chemical Properties | White Crystalline Powder | | Uses | The active component in the diuretic Diurex. | | Purification Methods | It is purified by dissolving in the minimum volume of dilute NaOH (charcoal), filtering and acidifying to pH ca 3.5-4. The solid that separates is collected, dried in vacuo at 100o and stored in a dark container. It has also been recrystallised from EtOH or AcOH.
