Kayzoni 250mg Capsules (Crizotinib)

Introduction

Kayzoni 250mg Capsules contain Crizotinib, a targeted anti-cancer medicine used for the treatment of specific types of advanced or metastatic cancers that carry certain genetic mutations. Crizotinib belongs to a class of medicines known as tyrosine kinase inhibitors (TKIs). It works by blocking abnormal proteins that promote the growth and spread of cancer cells, helping to slow disease progression and improve treatment outcomes. Crizotinib is primarily prescribed for patients with ALK-positive or ROS1-positive non-small cell lung cancer (NSCLC).

• Targeted therapy for genetically identified cancers
• Helps slow the growth and spread of cancer cells

Uses of Kayzoni 250mg Capsules

Kayzoni 250mg Capsules are commonly prescribed for:

ALK-Positive Non-Small Cell Lung Cancer (NSCLC)

Crizotinib is used in adults with advanced or metastatic NSCLC whose tumors test positive for anaplastic lymphoma kinase (ALK).

ROS1-Positive Non-Small Cell Lung Cancer

The medicine is also indicated for patients with ROS1-positive metastatic NSCLC, a rare genetic subtype of lung cancer.

Other Specialized Cancer Treatments

In certain cases, Crizotinib may be prescribed by oncology specialists for ALK-positive inflammatory myofibroblastic tumors (IMT) and ALK-positive anaplastic large cell lymphoma (ALCL).

How Kayzoni 250mg Works

Crizotinib targets and inhibits specific proteins known as ALK, ROS1, and MET kinases. These proteins can become abnormally active due to genetic mutations, leading to uncontrolled cancer growth. By blocking these signals, Kayzoni helps reduce tumor cell multiplication and may shrink existing tumors.
