Drug Information
Antithrombin III (ATI) is a naturally occurring protein that plays a crucial role in the body’s coagulation system. It belongs to the class of anticoagulant proteins, which inhibit the formation of blood clots.
Pharmacological Classification
- Anticoagulant
- Serine protease inhibitor
Mechanism of Action, Ati dosage calculation proctored exam answers
ATI acts as a potent inhibitor of thrombin, the enzyme responsible for converting fibrinogen into fibrin, the insoluble protein that forms blood clots. By binding to thrombin, ATI prevents it from interacting with fibrinogen, effectively blocking the formation of fibrin and subsequent clot formation.
Pharmacokinetic Properties
- Absorption:ATI is not absorbed orally and must be administered intravenously.
- Distribution:ATI distributes widely throughout the body, binding to endothelial cells and circulating in the plasma.
- Metabolism:ATI is primarily metabolized by the liver.
- Excretion:ATI is excreted in the urine.
Dosage Calculation
| Dosage Form | Strength |
|---|---|
| Intravenous Injection | 500 units/mL |
| Intravenous Infusion | 1,000 units/mL |
The appropriate dosage of ATI is determined based on the patient’s weight and the severity of their condition. The following formula is used to calculate the dosage:
Dosage (units) = Patient’s Weight (kg) x Desired Antithrombin Activity (%) x 50
For example, to calculate the dosage for a patient weighing 70 kg who requires an antithrombin activity of 80%, the formula would be:
Dosage (units) = 70 kg x 0.8 x 50 = 2,800 units
It is crucial to calculate the dosage accurately to ensure patient safety. Underdosing may not provide adequate anticoagulation, while overdosing can increase the risk of bleeding.
Proctored Exam Preparation

Exam Answers
Question 1:What is the pharmacological classification of ATI? Answer:Anticoagulant and serine protease inhibitor Question 2:Describe the mechanism of action of ATI. Answer:ATI binds to thrombin, preventing it from converting fibrinogen to fibrin, thereby inhibiting clot formation. Question 3:How is ATI administered? Answer:Intravenously Question 4:What is the formula used to calculate the dosage of ATI? Answer:Dosage (units) = Patient’s Weight (kg) x Desired Antithrombin Activity (%) x 50 Question 5:Why is accurate dosage calculation important? Answer:To ensure patient safety by providing adequate anticoagulation without increasing the risk of bleeding.
