Pulmonary Embolism

A pulmonary embolism (PE) occurs when a blood clot, usually formed in a deep vein of the leg, travels to the lungs and blocks one of the pulmonary arteries. It is a medical emergency. Classic symptoms include sudden breathlessness, sharp chest pain that worsens when breathing in, a rapid heart rate, and coughing up blood. Anyone with these symptoms should seek emergency care immediately.

Medicine used to treat Pulmonary Embolism

Anticoagulation: the core of PE treatment

Stopping the clot from growing and preventing new ones is the immediate priority. Anticoagulant medicines are the backbone of PE management, used both in hospital and during the weeks of recovery that follow. Direct oral anticoagulants have largely replaced older agents in many countries across South and Southeast Asia because they do not require routine blood-test monitoring. Rivaroxaban is one such agent, approved for the treatment of PE and for reducing the risk of recurrence. Treatment duration depends on whether the clot had an identifiable trigger or arose spontaneously; longer courses are used when the underlying risk persists. People with heart and blood pressure conditions may have additional considerations that affect which anticoagulant is chosen and for how long.
