Study Notes
Antiplatelet Drugs
- Aspirin, Ticlopidine, and Clopidogrel are all antiplatelet drugs.
- Antiplatelet drugs inhibit platelet aggregation, preventing blood clots from forming.
Parenteral Anticoagulant
- Heparin is classified as a parenteral anticoagulant.
- Heparin is administered intravenously or subcutaneously.
Fibrinolytic Drugs
- Fibrinolytic drugs are used to dissolve existing blood clots.
- They are used in the treatment of myocardial infarction, stroke, and pulmonary embolism.
Aspirin and Myocardial Infarction
- Aspirin is used to prevent recurrent myocardial infarction (heart attack).
- Aspirin inhibits platelet aggregation, preventing blood clots from forming in the coronary arteries.
Drug Classifications
- Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) with antiplatelet properties.
- Heparin is an anticoagulant.
- Ticlopidine and Clopidogrel are antiplatelet drugs.
- Fibrinolytics are a class of drugs that dissolve blood clots.
Side Effects of Antiplatelet Drugs
- Bleeding is a common side effect of Ticlopidine and Clopidogrel.
- This is because they inhibit platelet aggregation, which is essential for normal blood clotting.
Adverse Effects of Anticoagulant Therapy
- Bleeding is a major adverse effect associated with anticoagulant therapy.
- Other adverse effects include hematuria (blood in urine) and gastrointestinal bleeding.
Anticoagulant Overdose
- Protamine sulfate is an antidote for severe bleeding due to anticoagulant overdose.
- It binds to heparin, neutralizing its anticoagulant effects.
New Oral Anticoagulant
- Rivaroxaban is a new oral anticoagulant.
- It is a direct factor Xa inhibitor, meaning it directly inhibits the coagulation factor Xa, a key enzyme in the coagulation cascade.
Vitamin K Content
- Green leafy vegetables are considered to have a high vitamin K content.
- Vitamin K is essential for blood clotting and can affect the effectiveness of anticoagulants.
