    Which coagulation factors are inactivated by Heparin?

    • Factor X

    • FActor Xa, IXa IIa, XIa, XIIa =multisites of coag pathway + neutralises thromboplastin (factor III)

    • Antithrombin

    • Factor VII

    • FActor XIII

    Correct Answer
    A. FActor Xa, IXa IIa, XIa, XIIa =multisites of coag pathway + neutralises thromboplastin (factor III)
    Explanation
    Heparin inactivates Factor Xa, IXa, IIa, XIa, and XIIa, which are multiple sites in the coagulation pathway. Additionally, it neutralizes thromboplastin (Factor III).

    What is the principal anticoagulant action of heparin?

    • Binds factors IIA, IXa + Xa

    • Binds to factor X

    • Binds to antithrombin III

    • Binds to fibrin

    • Inhibits platelet aggregation

    Correct Answer
    A. Binds to antithrombin III
    Explanation
    Heparin's principal anticoagulant action is binding to antithrombin III. Antithrombin III is a natural anticoagulant protein in the body that inhibits the activity of several blood clotting factors, including factors IIa, IXa, and Xa. By binding to antithrombin III, heparin enhances its inhibitory effect on these clotting factors, preventing the formation of blood clots.

    Correct Answer
    naturally occuring mucopolysaccharide, anticoagulant, X, prothrombin, thrombin, fibrin, fibrin stabilising factor
    Explanation
    Heparin is a naturally occurring mucopolysaccharide with anticoagulant activity. It works by inactivating factor X and inhibiting the conversion of prothrombin to thrombin. Additionally, heparin further activates thrombin, preventing the conversion of fibrinogen to fibrin. Lastly, heparin inhibits the activation of fibrin stabilizing factor, thereby stopping the formation of a stable fibrin clot.

    What category of drug does Heparin belong to?

    • Anticoagulant

    • Haematologic drug

    • Haematologic drug + anticoagulant

    • NSAIDS

    • Antipsychotic

    Correct Answer
    A. Haematologic drug + anticoagulant
    Explanation
    Heparin belongs to the category of drugs known as haematologic drugs + anticoagulants. This is because Heparin is a medication that is commonly used as an anticoagulant, meaning it prevents the formation of blood clots. Additionally, Heparin is also classified as a haematologic drug because it is used to treat and prevent various disorders related to the blood and blood vessels.
