The effect of dexamethasone on platelet function.

K M Lichtenfeld, C A Schiffer

    Transfusion
    |March 1, 1979
    PubMed
    Summary

    Dexamethasone, a corticosteroid, minimally impacts platelet function and aggregation. While it may slightly prolong bleeding times in women, it does not cause clinically significant effects on hemostasis.

    Area of Science:

    • Pharmacology
    • Hematology
    • Clinical Medicine

    Background:

    • Corticosteroids like dexamethasone are widely used.
    • Understanding their effects on hemostasis is crucial for patient safety.

    Purpose of the Study:

    • To evaluate the impact of dexamethasone on platelet function and bleeding times.
    • To determine if dexamethasone causes clinically significant alterations in hemostasis.

    Main Methods:

    • Platelet aggregation studies were conducted on healthy adults and patients on daily dexamethasone.
    • Bleeding times were measured in volunteers before and after a single dexamethasone dose.

    Main Results:

    • Dexamethasone did not alter platelet aggregation in response to ADP, epinephrine, or collagen.
    • Bleeding times were moderately prolonged in women but not in men, with effects less pronounced than aspirin.
    • No subjects experienced delayed bleeding.

    Conclusions:

    • Single high doses of dexamethasone likely do not produce clinically significant effects on platelet function.
    • Dexamethasone's impact on hemostasis appears minimal, particularly compared to other medications like aspirin.
