Usage
- Hemocoagulase is prescribed to control bleeding during surgical procedures, after tooth extractions, and in individuals with bleeding disorders. It is also used in intensive care settings, particularly for mechanically ventilated patients.
- Pharmacological classification: Hemostatic agent.
- Mechanism of Action: Hemocoagulase acts as a topical hemostatic agent, promoting rapid blood clotting at the site of application.
Alternate Names
How It Works
- Pharmacodynamics: Hemocoagulase is a thrombin-like enzyme derived from snake venom (Bothrops atrox). It directly converts fibrinogen to fibrin, bypassing several steps in the coagulation cascade. This leads to the formation of a stable clot at the application site.
- Pharmacokinetics: Primarily acts locally. When administered intravenously, it has a short half-life and is rapidly cleared. Topical administration limits systemic absorption.
- Mode of Action: Directly converts fibrinogen to fibrin, leading to clot formation. Does not activate Factor XIII and as a result does not lead to cross-linking of fibrin monomers.
- Elimination pathways: Information on specific metabolic pathways and elimination routes is limited. Primarily metabolized and excreted locally when applied topically. Intravenous administration likely involves hepatic and renal clearance.
Dosage
Standard Dosage
Adults:
- Intravenous: 0.25 KU every 4-6 hours.
- Topical: 1 KU applied directly to the bleeding site.
Children:
- Dosage needs to be adjusted based on the child’s weight and the specific clinical situation. Pediatric safety considerations must be taken into account.
Special Cases:
- Elderly Patients, Patients with Renal Impairment, Patients with Hepatic Dysfunction, Patients with Comorbid Conditions: Dosage adjustments may be necessary based on the individual patient’s condition and should be determined by the treating physician.
Clinical Use Cases
- Intubation, Surgical Procedures, Mechanical Ventilation, Intensive Care Unit (ICU) Use, Emergency Situations: The dosage and administration route (intravenous or topical) will depend on the specific clinical situation.
Dosage Adjustments
- Dose modifications are based on patient-specific factors such as renal/hepatic function, coexisting medical conditions, and the severity of bleeding.
Side Effects
Common Side Effects
- Data on common side effects is limited based on the provided sources.
Rare but Serious Side Effects
Long-Term Effects
- Data on long-term effects is limited.
Adverse Drug Reactions (ADR)
- Severe allergic reactions require immediate medical attention.
Contraindications
- Known hypersensitivity to hemocoagulase or any component of the formulation.
Drug Interactions
- Limited information is available on specific drug interactions. Concomitant use with anticoagulants may theoretically reduce hemocoagulase’s efficacy.
Pregnancy and Breastfeeding
- The safety of hemocoagulase during pregnancy and breastfeeding has not been well established. It should be used with caution in these populations.
