Chloroquine

Introduction

Chloroquine is a widely used medication primarily prescribed for the prevention and treatment of malaria. It belongs to a class of drugs called antimalarials and works by killing the parasites that cause malaria. Apart from malaria, it is also used for treating autoimmune diseases like rheumatoid arthritis and lupus due to its anti-inflammatory properties. Chloroquine has been in use for decades and remains a key medicine in areas where malaria is prevalent. However, due to increasing resistance, its use is now limited to specific cases. Always take chloroquine under medical supervision to ensure safe and effective treatment.

Uses of Chloroquine

• Treatment and prevention of malaria
• Management of rheumatoid arthritis
• Treatment of systemic lupus erythematosus (SLE)
• Used in certain viral infections under medical guidance
• Helps control inflammation in autoimmune conditions

How Chloroquine Works

Chloroquine works by interfering with the growth and replication of the malaria parasite inside red blood cells. It increases the pH levels in the parasite` s food vacuole, disrupting its ability to digest hemoglobin, ultimately leading to the parasite` s death. In autoimmune diseases, chloroquine helps regulate the immune system and reduce inflammation, preventing joint and tissue damage.

Always take it with food to reduce stomach discomfort and follow the prescribed schedule strictly.
