Dipyrone effectively treats episodic tension-type headaches and migraines in adults. While no serious adverse events were noted in trials, the rare risk of agranulocytosis requires ongoing study.

Area of Science:

  • Pharmacology and Therapeutics
  • Clinical Trials and Evidence Synthesis
  • Pain Management

Background:

  • Dipyrone is widely used for headaches but restricted in some countries due to rare blood dyscrasia risks.
  • Concerns exist regarding dipyrone's safety profile, specifically agranulocytosis.
  • The effectiveness and safety for acute primary headaches require thorough investigation.

Purpose of the Study:

  • To evaluate the efficacy and safety of dipyrone for acute primary headaches.
  • To synthesize evidence from randomized controlled trials on dipyrone's use in adults and children.
  • To determine dipyrone's effectiveness compared to placebo and other analgesics.

Main Methods:

  • Systematic review of double-blind randomized controlled trials.

  • Searched multiple databases including Cochrane, MEDLINE, EMBASE, and LILACS.
  • Data extraction and analysis included relative risks and weighted mean differences.

    • Main Results:

    • Four trials with 636 adults were included; no pediatric trials were identified.
    • Dipyrone demonstrated significant effectiveness for episodic tension-type headache and migraine pain relief compared to placebo.
    • No serious adverse events were reported; dipyrone showed comparable safety to placebo and acetylsalicylic acid in the trials.

    Conclusions:

    • Dipyrone is an effective treatment for acute primary headaches, including episodic tension-type headache and migraine.
    • The available trial data did not reveal serious adverse events, but rare risks like agranulocytosis need further monitoring.
    • Ongoing studies aim to further clarify the safety profile of dipyrone, particularly concerning agranulocytosis.
