SlimWorks Keto Methylxanthines (Theophylline) and other available bronchhodilator drugs have various properties that might make them useful in certain cases. Theophylline (Theo-Dur, Uniphyl) is a drug given orally (tablets). This can have a continuous effect on keeping the airway open. Theophylline levels must be monitored by blood tests. Too much theophylline can cause an overdose, but if it is too little, this drug will not have enough effect to relieve breathing. In addition, other drugs can interact with theophylline, changing their blood levels without being noticed. For this reason, doctors now prescribe theophylline very carefully taking into account the potential for other drug interactions. http://leoalexanderformayor.com/
