Indications of Palboxen 125 mg
Palboxen 125 mg is primarily prescribed for the treatment of hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced or metastatic breast cancer. This medication is an essential component of targeted therapy and is typically used in combination with hormone (endocrine) therapies such as aromatase inhibitors or fulvestrant. It is especially indicated for patients with estrogen receptor-positive (ER+) breast cancer who may not respond to traditional chemotherapy. Palboxen works to slow cancer progression and can help to delay tumor growth when used alongside endocrine treatments.
Due to its mechanism of action, Palboxen 125 mg is beneficial for postmenopausal women as a first-line therapy when combined with aromatase inhibitors. It also serves as an effective treatment option for patients whose disease has progressed after previous endocrine therapy when combined with fulvestrant.
Therapeutic Class
Palboxen 125 mg belongs to the therapeutic class of cyclin-dependent kinase (CDK) inhibitors, specifically targeting CDK4 and CDK6. These are enzymes that regulate the progression of the cell cycle, particularly the transition from the G1 to the S phase, which is crucial for cell division and proliferation. In cancer cells, especially those in estrogen receptor-positive (ER+) breast cancer, CDK4/6 plays a significant role in promoting uncontrolled growth.
By inhibiting CDK4 and CDK6, Palboxen effectively slows down cell division, reducing the proliferation of cancer cells. This class of drugs is part of targeted therapy, which focuses on specific mechanisms of cancer cells, allowing for more precise and effective treatment with fewer side effects than conventional chemotherapy.

Pharmacology
Palboxen 125 mg contains the active ingredient palbociclib, which exerts its pharmacological action by selectively inhibiting CDK4 and CDK6. These kinases are essential for transitioning cancer cells from the G1 phase to the S phase of the cell cycle. By blocking CDK4/6 activity, Palboxen 125 mg prevents cancer cells from progressing through the cell cycle, thus halting their division and proliferation. This interruption of the cell cycle is particularly effective in estrogen receptor-positive (ER+) breast cancer cells, where estrogen signaling drives cancer cell growth.
Furthermore, the combination of Palboxen 125 mg with endocrine therapies, such as aromatase inhibitors or fulvestrant, enhances its effectiveness. By reducing the phosphorylation of the retinoblastoma protein (Rb), Palboxen 125 mg decreases E2F signaling, a critical pathway involved in cell proliferation. This dual inhibition results in a potent anti-cancer effect, which significantly slows tumor growth and improves the overall outcome for patients with HR+, HER2- breast cancer.
Dosage of Palboxen 125 mg
The recommended dosage of Palboxen 125 mg is one 125 mg tablet taken orally once a day, for 21 consecutive days, followed by a 7-day break. This forms a 28-day treatment cycle, which should be repeated throughout the course of therapy. The dosage may need adjustment depending on the patient’s tolerance, blood test results (especially white blood cell counts), and any side effects experienced during treatment.
If a dose is missed, it should be skipped, and the patient should proceed with the next scheduled dose. It is important not to double doses to make up for a missed one, as this could lead to an overdose or exacerbate side effects. Always follow the prescribed dosage regimen strictly and consult with your healthcare provider before making any changes.
Administration of Palboxen 125 mg
Palboxen 125 mg should be taken orally, with food, at the same time every day. It is crucial to swallow the tablet whole, as crushing, chewing, or breaking the tablet may alter its efficacy. Taking the medication with food can help minimize gastrointestinal side effects such as nausea or upset stomach.
Patients are advised to follow a consistent schedule for taking the medication, ensuring it is taken at the same time each day. If a dose is missed, the patient should skip it and take the next dose at the usual time. Do not take additional doses to compensate for a missed dose.
Interaction of Palboxen 125 mg
Palboxen 125 mg may interact with other medications, which could either increase the risk of side effects or reduce the drug’s effectiveness. For example, medications that inhibit the enzyme CYP3A (such as ketoconazole) may increase the levels of Palboxen 125 mg in the blood, potentially leading to heightened side effects. On the other hand, drugs that induce CYP3A (such as rifampin) may reduce the effectiveness of Palboxen 125 mg.
Additionally, certain medications such as anticoagulants, antifungals, or antivirals may interact with Palboxen 125 mg, requiring dose adjustments or close monitoring during treatment. It is essential to inform your healthcare provider about all the medications, supplements, or herbal products you are taking to prevent potential interactions.
