How should blood pressure be managed before administering IV tPA?

• A. Lower to SBP <185 and DBP <110 before tPA; avoid rapid, large reductions
• B. Keep BP below 120/80
• C. Lower to SBP <200 and DBP <120
• D. No BP management is required before tPA

Answer: (A)

Before giving IV tPA, bring blood pressure down to a systolic <185 and diastolic <110 mm Hg, and do so gradually rather than with sudden large drops. This threshold minimizes the risk of hemorrhagic transformation during thrombolysis while still preserving cerebral perfusion. If BP is above this level, use IV antihypertensives (such as labetalol, nicardipine, or clevidipine) to lower it to target before initiating tPA. Once tPA is underway or completed, continue to keep BP below 180/105 to reduce bleeding risk.
