Usage
- Benzyl Nicotinate + Heparin is prescribed for the treatment of superficial thrombophlebitis, a condition characterized by inflammation and swelling of a vein just beneath the skin due to a blood clot. It is also used to relieve pain and inflammation associated with varicose veins, hemorrhoids, bruises, and swelling from injuries or surgery.
- Pharmacological classification: This combination medication falls under two categories: vasodilators (benzyl nicotinate) and anticoagulants (heparin).
- Mechanism of Action: Benzyl nicotinate dilates blood vessels, increasing blood flow to the affected area. Heparin acts as an anticoagulant, preventing further clot formation and promoting the dissolution of existing clots. The combined effect reduces pain, inflammation, and promotes healing.
Alternate Names
- No widely recognized alternate names exist for this specific combination.
- Brand names: Thrombophob, Thrombotas, Thromnix, Thrombonot, Thrombozen H, Thermothur.
How It Works
- Pharmacodynamics: Benzyl nicotinate causes vasodilation, increasing blood flow to the application site. Heparin prevents clot formation by activating antithrombin III, which inhibits thrombin and other clotting factors.
- Pharmacokinetics: The combination is applied topically. Benzyl nicotinate enhances local absorption of heparin. Heparin’s systemic absorption is minimal with topical application. Metabolism and elimination pathways for topical application are not well-defined.
- Mode of action: Benzyl nicotinate exerts its vasodilatory effect by relaxing smooth muscle in blood vessels. Heparin binds to antithrombin III, accelerating its inactivation of clotting factors.
- Receptor binding, enzyme inhibition, neurotransmitter modulation: Benzyl nicotinate’s vasodilatory mechanism is not fully elucidated, but it may involve nitric oxide pathways. Heparin primarily inhibits thrombin and other clotting factors through its interaction with antithrombin III.
- Elimination pathways: Minimal systemic absorption occurs with topical heparin. Benzyl nicotinate’s elimination pathways after topical administration are not well-characterized.
