What is Letrozole?
Letrozole, the active ingredient in Letrozole Pharmacare, is an aromatase inhibitor presented as an oral tablet for oral use. It is indicated for the treatment of postmenopausal hormone receptor‑positive breast cancer, reducing estrogen‑driven tumor growth.
GNH USA supplies Letrozole Pharmacare as a licensed, GDP‑compliant international pharmaceutical supplier serving oncology centres worldwide.
What is Letrozole used for?
Letrozole acts on estrogen‑dependent breast cancer pathways and is used in several clinical settings. - Postmenopausal hormone receptor‑positive breast cancer: reduces tumor progression by lowering circulating estrogen levels. - Adjuvant therapy of early‑stage hormone‑dependent breast cancer: helps prevent recurrence after surgery. - Metastatic hormone‑dependent breast cancer: slows disease spread in advanced cases.
What are the side effects of Letrozole?
Letrozole may cause a range of adverse reactions, varying from mild to severe.
Common Side Effects: - Hot flashes: sudden feeling of warmth and sweating. - Joint or muscle pain: arthralgia or myalgia. - Fatigue: persistent tiredness. - Nausea: mild gastrointestinal upset. - Headache: tension‑type or migraine‑like pain.
Serious or Rare Side Effects: - Osteoporosis or bone fractures: decreased bone mineral density. - Severe liver injury: elevated transaminases or hepatitis. - Cardiovascular events: thromboembolism or myocardial infarction. - Allergic reactions: rash, pruritus, or anaphylaxis. - Elevated cholesterol: significant dyslipidemia.
What precautions apply to Letrozole?
When prescribing Letrozole, clinicians should consider several safety measures. - Assess bone health: baseline DEXA scan and monitor for osteoporosis. - Monitor liver function: periodic liver enzyme tests. - Evaluate cardiovascular risk: check blood pressure and lipid profile. - Counsel on menopausal symptoms: manage hot flashes and vaginal dryness. - Review concomitant medications: avoid drugs that strongly affect CYP2A6. - Store at ambient temperature: keep below 25 °C in original packaging, protect from moisture.
What does Letrozole interact with?
Letrozole can interact with other medicines that affect its metabolism or hormonal pathways.
Major Interactions (Avoid): - Strong CYP2A6 inhibitors (e.g., ketoconazole): may increase Letrozole exposure. - Estrogen‑containing therapies (e.g., hormone replacement): counteract therapeutic effect. - Tamoxifen: antagonistic action on estrogen pathways.
Moderate Interactions (Monitor Closely): - Warfarin: potential alteration of anticoagulant effect. - Corticosteroids: may affect bone density when combined. - Antidepressants (SSRIs): possible impact on estrogen metabolism. - Anticonvulsants (e.g., carbamazepine): may reduce Letrozole levels. - Herbal supplements (St. John’s wort): may induce metabolism.
