While many medications have weight-related side effects, clinical studies have not identified weight gain as a direct side effect of Eliquis. However, many patients start taking Eliquis (apixaban) after a major health event, which can lead to lifestyle changes that contribute to weight gain.

Despite some confusion, metoprolol is explicitly not a blood thinner but a beta-blocker used to treat high blood pressure and other heart conditions. It is crucial for patients to understand this fundamental distinction, as these medications work in entirely different ways to manage cardiovascular health.

According to the American Stroke Association, ischemic strokes account for approximately 87% of all stroke cases, making it the most common type. Determining **what is the drug of choice for a stroke patient** depends entirely on whether the stroke is caused by a clot (ischemic) or bleeding (hemorrhagic), highlighting the need for a rapid and accurate diagnosis.

Antithrombin is a critical protein that accounts for up to 80% of the inhibition of thrombin, a key enzyme in blood clot formation [1.2.1, 1.6.3]. So, **what does antithrombin do to thrombin?** It acts as a natural anticoagulant, neutralizing thrombin's activity to maintain hemostatic balance and prevent excessive clotting [1.6.2].

Antithrombin is a natural anticoagulant that accounts for up to 80% of the inhibition of thrombin formation in the body [1.2.1]. The critical question is, what is the mechanism of action of heparin antithrombin 3 that so dramatically enhances this effect to prevent blood clots?

Antithrombin, commonly known as antithrombin 3 (AT3), accounts for up to 80% of the anticoagulant activity in blood plasma and is crucial for regulating the body's clotting process. This protein's primary purpose is to inhibit several key enzymes in the coagulation cascade, preventing the formation of dangerous blood clots.

In 2022, approximately 3.5 million Medicare Part D enrollees filled prescriptions for the anticoagulant Eliquis (apixaban) [1.7.1]. A common question for these patients is, 'What foods should I avoid while on Eliquis?' to ensure safety and efficacy.

The annual risk of major bleeding for patients using oral anticoagulants ranges from 2% to 5% [1.2.2]. The critical question, 'Does anticoagulant cause bleeding?', is best answered by understanding that bleeding is not just a side effect, but an extension of the medication's intended purpose [1.2.2, 1.3.3].

The incidence of hospital-acquired deep vein thrombosis (DVT) can be as high as 40–60% for patients after major orthopedic surgery if no preventive anticoagulants are used [1.3.4]. A common question in pharmacology is whether heparin, a cornerstone anticoagulant, is a direct thrombin inhibitor. The answer is no; it functions as an **indirect** thrombin inhibitor [1.4.3].

Heparin is a powerful anticoagulant medication widely used in medicine, with studies showing its anti-thrombotic activity is primarily mediated by potentiating the natural inhibitor, antithrombin. By doing so, it effectively inhibits the intrinsic and common pathways of the coagulation cascade.
