Which patients are not recommended to take estramustine (Adelax) and the potential risks

Estramustine (Estramustine) is a drug commonly used in the treatment of prostate cancer. Its main mechanism of action is to interfere with the microtubule structure of tumor cells, thereby inhibiting the division and proliferation of cancer cells. However, due to its pharmacological properties and potential side effects, not all patients are suitable for this drug.

First, estramustine should be used with caution in patients at risk for blood clots or thrombotic disorders. This drug may increase the tendency of the blood to clot, increasing the risk of serious complications such as deep vein thrombosis and pulmonary embolism. Therefore, patients with a history of thrombosis, abnormal coagulation function, or long-term bed rest should weigh the pros and cons under the guidance of a doctor and avoid use if necessary.

Secondly, patients with liver dysfunction are not recommended to take estramustine. Drugs are metabolized in the liver. If the patient's liver function is impaired, slowed drug metabolism may lead to an increase in blood drug concentration, thereby increasing the probability of toxic side effects, including hepatotoxic reactions and other systemic adverse reactions. Caution is also required in patients with renal insufficiency as the excretion of the drug and its metabolites may be affected.

In addition, patients with cardiovascular disease and elderly patients need to pay special attention when using estramustine. Medications may cause cardiovascular burden such as high blood pressure and water retention, while increasing the risk of irregular heartbeats. For pregnant and lactating women, estramustine is contraindicated due to its potential teratogenic risks and effects on milk secretion. In short, the patient's past medical history and potential risks should be carefully assessed before use, and the doctor's instructions should be strictly followed for individualized treatment.
