Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.
Professional:Methylxanthines may antagonize the sedative effects of benzodiazepines. Aminophylline in particular has been demonstrated to attenuate the sedative effects of diazepam. The mechanism of this interaction may be related to competitive binding to intracerebral adenosine receptors. One study demonstrated that alprazolam serum concentrations were significantly lower in patients receiving chronic theophylline therapy than in patients not receiving theophylline. Clinical and laboratory monitoring is warranted if these agents are given concurrently. Patients receiving this combination should be monitored for adequate response to the benzodiazepine.
