      Mechanism Description
  • Antagonize the effect of Guanadrel when combined with Isometheptene 

Recommended Action
      Management Due to their pressor effect, sympathomimetic amines should be used cautiously in patients with hypertension. alternatives to postganglionic adrenergic blocking agents should be considered if patients are treated with sympathomimetic amines, since effects of the latter may be intensified or diminished depending on whether they are direct- or indirect-acting. Most agents with indirect sympathomimetic activity are mixed-acting, thus it may be difficult to predict how they will be affected by postganglionic adrenergic blocking agents. If the combination is used, blood pressure and heart rate should be monitored.
