What is Selinexor 20 mg Tablet?

Selinexor 20 mg Tablet is an oral anti-cancer medicine used to treat certain relapsed or refractory blood cancers. It is a first-in-class targeted therapy belonging to a group of medicines known as Selective Inhibitors of Nuclear Export (SINE). Selinexor works by interfering with cellular mechanisms that allow cancer cells to survive and evade programmed cell death.

Selinexor is the active ingredient in the original reference brand, Xpovio®, and generic formulations are designed to provide therapeutic equivalence under approved regulatory standards.

Selinexor is prescribed under specialist supervision for patients with advanced malignancies who have limited treatment options or whose disease has returned after previous therapies.

Uses of Selinexor 20 mg Tablet

Selinexor is indicated for adult patients with the following conditions:

Multiple Myeloma

• Relapsed or refractory multiple myeloma.
• Used alone or in combination with other anti-cancer medicines.
• Suitable for patients who have received previous lines of therapy.
• Helps slow disease progression and induce cancer cell death.

Diffuse Large B-Cell Lymphoma (DLBCL)

• Relapsed or refractory DLBCL not otherwise specified.
• For patients who are not eligible for certain intensive treatments.
• May help reduce tumor burden and delay disease progression.

How Selinexor Works

Selinexor targets a protein called Exportin-1 (XPO1), which transports tumor suppressor proteins out of the cell nucleus. Many cancer cells overexpress XPO1, allowing them to escape normal growth regulation.

Mechanism of Action

• Inhibits the activity of the XPO1 protein.
• Prevents tumor suppressor proteins from leaving the nucleus.
• Restores the natural ability of cells to control abnormal growth.
• Triggers programmed cancer cell death (apoptosis).
• May reduce the proliferation of malignant cells while minimizing damage to normal cells.

Dosage and Administration

The dosage, treatment schedule, and duration of therapy should always be determined by a qualified oncologist based on the patient’s diagnosis, previous treatments, and overall health status.

Administration Guidelines

• Take Selinexor exactly as prescribed by your doctor.
• Swallow the tablets whole with water.
• May be taken with or without food.
• Often administered in combination with corticosteroids or other anti-cancer medicines.
• Take doses on the specific days recommended by your healthcare provider.
