Name the pharmaceutical agent that is strictly contraindicated in patients with hemophilia_________________?
Show answer Hide answer
Answer: A. Aspirin
Explanation
Aspirin irreversibly inhibits platelet cyclooxygenase and suppresses normal platelet aggregation. Hemophiliacs suffer from inherent clotting factor deficiencies that impair normal hemostasis. Combining impaired clotting factors with inhibited platelets causes uncontrollable bleeding episodes. Hemophilia is a genetic bleeding disorder involving missing coagulation factors like eight or nine. Normal hemostasis requires both intact coagulation cascades and functional platelet aggregation. Antiplatelet drugs pose severe hemorrhage risks in patients with underlying bleeding diatheses.
Patients with hemophilia must avoid all aspirin and nonsteroidal anti-inflammatory medications. Dental extractions in bleeding disorders require specialized hematological preparation and support. Careful medication reconciliation prevents accidental administration of contraindicated anticoagulants. Penicillinium is a fungal source for antibiotics and lacks antiplatelet properties. Amino epsilon caproic acid is an antifibrinolytic agent actually used to promote blood clotting. Diphenylhydantoin is an anticonvulsant medication unrelated to acute hemophilic bleeding risks.
