Therapeutic Strategies for Patient Safety.

American journal of therapeutics·2025

Multiple drug intolerance (MDI) affects 2-5% of the population, complicating hypertension management. A novel algorithm successfully controlled blood pressure in a patient with multiple drug-intolerant hypertension (MDI-HTN) without adverse reactions.

Area of Science:

  • Cardiology
  • Clinical Pharmacology

Background:

  • Multiple drug intolerance (MDI) is defined as adverse drug reactions to over 3 medication classes without immunological cause.
  • Multiple drug-intolerant hypertension (MDI-HTN) presents a significant therapeutic challenge, leading to treatment non-adherence and poor blood pressure control.
  • MDI affects 2-5% of the population, often with comorbidities and high cardiovascular risk, yet hypertension guidelines lack specific management algorithms for MDI-HTN.

Observation:

  • A 63-year-old male patient presented with third-degree hypertension and documented intolerance to 4 major antihypertensive drug classes.
  • Current hypertension management guidelines do not offer a clear strategy for patients with MDI-HTN.
  • The patient exhibited high cardiovascular risk and numerous comorbidities, further complicating treatment decisions.

Findings:

  • A recently proposed four-step algorithm was implemented for MDI-HTN management over a 1-month follow-up period.
  • The strategy involved cautious re-administration of previously intolerant drug classes at lower doses and in combination, prioritizing agents with fewer side effects.
  • The patient achieved satisfactory blood pressure control (135.5/83.0 mm Hg via 24-hour ABPM) without reported adverse drug reactions.

Implications:

  • The successful application of the four-step algorithm demonstrates a viable approach to managing MDI-HTN.
  • This strategy offers a potential solution for treatment-resistant hypertension in patients with multiple drug intolerances.
  • Further research and integration of this algorithm into clinical practice could improve outcomes for a challenging patient population.
