Lorlatinib

Introduction

Lorlatinib is an anti-cancer medicine mainly used to treat certain types of lung cancer. It belongs to a class of medicines called targeted therapy, which works by blocking specific proteins responsible for the growth and spread of cancer cells. Lorlatinib is usually prescribed for patients with ALK-positive non-small cell lung cancer (NSCLC), especially when other treatments are not effective or have stopped working. This medicine should be taken only under the supervision of an oncologist (cancer specialist). Regular medical monitoring and follow-ups are important during treatment to check its effectiveness and manage side effects safely.

Uses of Lorlatinib

• Treatment of ALK-positive non-small cell lung cancer
• Treatment of ROS1-positive non-small cell lung cancer
• Used in patients who have progressed on other ALK inhibitors

How Lorlatinib Works

Lorlatinib works by inhibiting the activity of abnormal ALK and ROS1 proteins, which are involved in the growth and spread of cancer cells. By blocking these proteins, Lorlatinib slows down or stops cancer progression.
