Abstract: Objective To investigate the clinical characteristics, management strategies and outcomes of extremely severe thrombocytopenia induced by tirofiban. Methods One case of severe thrombocytopenia induced by tirofiban was analyzed, the correlation between thrombocytopenia and tirofiban was studied, and related literature was retrieved before the mechanisms underlying tirofiban-induced thrombocytopenia were investigated. Results Tirofiban was discontinued immediately after detection of the adverse reaction, followed by quick symptomatic treatment. Subsequent blood routine indices returned to normal, clinical parameters were stabilized, and the patient showed favorable recovery with a good prognosis. Conclusion Cases of extremely severe thrombocytopenia caused by tirofiban are relatively rare. Clinical pharmacists’ analysis of the treatment process can facilitate individualized medications in similar cases. It is recommended that clinicians monitor platelet counts while tirofiban is used and remain vigilant against adverse reactions.
