title: Blood pressure elevation in a patient treated with salsalate.
abstract: OBJECTIVE
  To report a case of increased blood pressure associated with the use of salsalate in an elderly patient with no prior history of hypertension.
  
  
  METHODS
  A 78-year-old white man with no prior history of hypertension initiated salsalate therapy for low-back pain. Over the 15 months prior to the initiation of salsalate, his blood pressure averaged 127 +/- 7 mm Hg systolic and 84 +/- 6 mm Hg diastolic (mean +/- SD). After initiation of salsalate, he experienced significant elevations in blood pressure, which led to a preliminary diagnosis of hypertension. Blood pressure after initiation of salsalate averaged 150 +/- 13 mm Hg systolic and 95 +/- 5 mm Hg diastolic. No changes in medications or medication doses (with the exception of warfarin) occurred in the 18 months prior to or during salsalate therapy. His weight remained stable. A detailed review of his medical records and history revealed no other causes for these elevations in blood pressure. Salsalate therapy was discontinued and his blood pressure returned to normotensive levels (119 +/- 2 mm Hg systolic and 81 +/- 2 mm Hg diastolic).
  
  
  CONCLUSIONS
  Nonsteroidal antiinflammatory drug (NSAID)-induced elevations in blood pressure have been well documented in patients receiving antihypertensive medications. Due to its relative weak inhibition of cyclooxygenase and lack of published literature in hypertensive patients, salsalate is considered to have little or no effect on blood pressure. Our report documents a possible case of salsalate-induced hypertension in a previously normotensive elderly man. Observational studies suggest that NSAID use may increase the risk of developing hypertension in older patients.
  
  
  CONCLUSIONS
  Clinicians should be aware of the possible effects of NSAIDs on blood pressure. Blood pressure monitoring following the initiation of salsalate may be warranted, particularly in older patients.
