🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a potent and selective non-steroidal aromatase inhibitor. It binds reversibly to the heme iron of the aromatase enzyme (CYP19A1), thereby blocking the conversion of androgens such as androstenedione and testosterone to estrone and estradiol. This leads to a significant reduction in circulating estrogen levels, which in turn deprives estrogen-dependent breast cancer cells of their growth stimulus. In premenopausal women, the ovaries are the main source of estrogen, and aromatase inhibition alone is insufficient to suppress estrogen; therefore, this medicine is typically used in postmenopausal women or in combination with ovarian suppression.
Mechanism Steps
💡 How to Take arolet tablet
Strength: Arolet tablet contains 2.5 mg of letrozole. The dosage form is a tablet for oral administration.
Dosage Information
| Adult Dosage | The usual adult dose of this medicine for breast cancer is 2.5 mg taken orally once daily, with or without food. For ovulation induction, the dose is typically 2.5 mg to 5 mg once daily for 5 days, starting on day 3 to 5 of the menstrual cycle. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | No dose adjustment is required for elderly patients based on age alone. However, elderly patients may be more susceptible to side effects such as bone loss and cardiovascular events, and should be monitored closely. |
| Renal Impairment | No dose adjustment is required for patients with renal impairment. However, caution is advised in severe renal impairment (creatinine clearance <10 mL/min) as letrozole has not been studied extensively in this population. |
| Hepatic Impairment | In patients with mild to moderate hepatic impairment, no dose adjustment is needed. In severe hepatic impairment, the dose should be reduced by 50% (i.e., 2.5 mg every other day) due to increased exposure. |
| Maximum Daily Dose | The maximum recommended daily dose is 2.5 mg for breast cancer. For ovulation induction, doses up to 7.5 mg daily have been used in clinical trials, but must be under specialist supervision. |

Additional Safety Advice
This medicine should only be taken under the supervision of a qualified oncologist or gynecologist. Do not share it with others, even if they have similar symptoms. Inform your doctor about all other medications, supplements, and herbal products you are taking, as interactions can occur. Use effective non-hormonal contraception during treatment if you are of childbearing potential, as this medicine can harm an unborn baby. Avoid driving or operating heavy machinery if you feel dizzy or fatigued. Regular monitoring of bone health, liver function, and cholesterol levels is recommended. Do not stop taking this medicine without consulting your doctor, as it may affect treatment outcomes.
👴 Special Considerations for Elderly
💡 For Patients Above 65
Elderly patients may be more susceptible to side effects such as bone loss, cardiovascular events, and liver enzyme abnormalities. Regular monitoring of bone density, lipid profile, and liver function is recommended. Dose adjustment is not required based on age alone, but caution is advised.
🤰 Pregnancy Planning (TTC)
This medicine is contraindicated in pregnancy and should not be used by women planning to conceive. If you are planning pregnancy, consult your doctor to stop this medicine and switch to a safer alternative. Use effective contraception during treatment and for at least 3 weeks after the last dose.
🏥 Post-Surgery Considerations
After surgery for breast cancer, this medicine may be prescribed as adjuvant therapy to reduce the risk of recurrence. It is usually started after surgery and continued for several years. Follow your surgeon's and oncologist's advice regarding wound care and activity restrictions.
🦷 Dental Procedures
Inform your dentist that you are taking this medicine. There is no specific contraindication for dental procedures, but if you have bone loss, caution is advised with dental implants or extractions. Maintain good oral hygiene.
💚 Lifestyle Tips for Better Results
🏋️ Exercise Considerations
Regular exercise is encouraged, but if you experience joint pain or bone pain, modify activities to low-impact exercises such as swimming or cycling. Avoid high-impact activities that may increase fracture risk if you have osteoporosis. Consult your doctor before starting any new exercise regimen.
🥗 Diet Recommendations
💼 Impact on Daily Work & Life
This medicine may cause fatigue, dizziness, or joint pain, which can affect your ability to drive or operate machinery. Avoid driving until you know how it affects you. Most patients can continue their normal daily activities, but listen to your body and rest when needed. Inform your employer if you need accommodations.
🛑 When to Stop This Medicine
Do not stop taking this medicine without consulting your doctor. For breast cancer, treatment is typically continued for 5 years unless disease progression or unacceptable side effects occur. For ovulation induction, it is stopped after the prescribed course. If you experience severe side effects, contact your doctor immediately; they may adjust the dose or switch to an alternative.
📅 Long-Term Use Effects
Long-term use of this medicine can lead to decreased bone mineral density, increasing the risk of osteoporosis and fractures. Regular monitoring of bone health with DEXA scans is recommended, and calcium and vitamin D supplements may be advised. It can also cause elevated cholesterol levels and cardiovascular events. Liver function should be monitored periodically. The benefits of long-term use in breast cancer outweigh the risks for most patients, but regular follow-up is essential.

🛑 Myths vs. Facts

Fact: Letrozole is an aromatase inhibitor that lowers estrogen levels, whereas hormone replacement therapy adds hormones to the body. - Myth: Letrozole can be taken by premenopausal women without any additional treatment.
Fact: In premenopausal women, letrozole alone is not effective for breast cancer because the ovaries produce high estrogen levels; it must be combined with ovarian suppression. - Myth: Letrozole causes immediate menopause.
Fact: Letrozole reduces estrogen but does not cause immediate menopause; it may cause menopausal symptoms like hot flashes.
