Nitroglycerin kan give hypertension

The patient was an 82-year-old woman with orthostatism, who was administrated one normal dose of glycerylnitrate as a part of a tilt table test. The following ten minutes after administration, a paradoxical and significant blood pressure response was registered in the form of a rise to 205/111 mmHg. The conclusion was that her response was a paradoxical response to glycerylnitrate, orthostatism and a pathological response to massage of the carotid artery. This is the third reported case on paradoxical hypertension induced by glyceryl nitrates. It is speculated that dysfunction of the cerebral bloodflow autoregulation may be one of the causes of this phenomenon.
