Letrozole: What Is It?

Letrozole is a medication primarily used in the treatment of hormone-receptor-positive breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by lowering estrogen levels in the body. This reduction in estrogen is crucial because many types of breast cancer depend on the hormone to grow and multiply.

How Does Letrozole Work?

When discussing letrozole what is, it’s essential to understand its mechanism of action. The drug inhibits the aromatase enzyme, which is responsible for converting androgens (male hormones) into estrogens (female hormones). By blocking this conversion, letrozole effectively decreases the overall estrogen levels in the bloodstream, slowing the growth of estrogen-dependent tumors.

Indications for Use

Letrozole is primarily prescribed for:

• Postmenopausal women with early-stage breast cancer.
• Women who have already undergone surgery or radiation therapy.
• Patients with metastatic breast cancer that is hormone receptor-positive.

Dosage and Administration

The standard dosage of letrozole is typically one 2.5 mg tablet taken once daily. It can be taken with or without food, but consistency in how it is taken each day is important for maintaining stable drug levels in the body. Patients should follow their healthcare provider’s instructions regarding dosage and duration of treatment.

Potential Side Effects

Letrozol Zentiva Filmtabletten 2.5mg 100 letrozole may cause side effects. Common side effects include:

• Hot flashes
• Joint pain or stiffness
• Fatigue
• Nausea
• Bone thinning (osteoporosis)

It’s vital for patients to discuss any concerning side effects with their healthcare provider, as some may require monitoring or intervention.

Conclusion

In summary, understanding letrozole what is involves recognizing its role as an effective treatment option for specific types of breast cancer. Its ability to lower estrogen levels makes it a valuable tool in managing hormone-receptor-positive tumors. As always, individuals should consult with their healthcare professionals to determine if letrozole is the right choice for their treatment plan.
