Area of Science:

  • Cardiology
  • Pharmacology

Background:

  • Severe hypertension requires effective treatment.
  • Oral captopril has a slow onset of action, limiting its use in hypertensive emergencies.
  • Sublingual administration of captopril may offer a faster therapeutic effect.

Purpose of the Study:

  • To evaluate the efficacy and safety of sublingual captopril 50 mg in patients experiencing a hypertensive crisis.

Main Methods:

  • A study involving 26 patients diagnosed with hypertensive crisis.
  • Administration of 50 mg of captopril via sublingual route.
  • Monitoring of blood pressure response over a two-hour period.

Main Results:

  • Significant reduction in blood pressure observed within 10 minutes of administration.

  • Maximum hypotensive effect achieved at 30 minutes post-administration.
  • Mean systolic blood pressure decreased from 202.5 mmHg to 160.6 mmHg.
  • Mean diastolic blood pressure decreased from 105.6 mmHg to 86.9 mmHg.
  • The blood pressure-lowering effect was sustained for over two hours.
  • No adverse side effects were reported during the study.

    • Conclusions:

    • Sublingual captopril is a highly effective treatment for hypertensive crisis.
    • The gradual hypotensive action of sublingual captopril prevents dangerous abrupt drops in blood pressure.
    • Sublingual captopril presents a safe and rapid alternative for managing hypertensive emergencies.
