Hydroxychloroquine and Chloroquine: Drug Classification and Uses

Introduction Hydroxychloroquine and chloroquine are medications primarily known for their antimalarial properties. They belong to a specific class of drugs and have various applications in medical treatments. This essay delves into their classification, mechanisms, and uses.

Drug Classification

1. Antimalarials Both hydroxychloroquine and chloroquine are classified as antimalarial drugs. They are used to prevent and treat malaria, a disease caused by parasites transmitted through the bites of infected mosquitoes¹.

2. Disease-Modifying Antirheumatic Drugs (DMARDs) Hydroxychloroquine is also classified as a DMARD. These drugs are used to treat autoimmune diseases by slowing down the overactive immune system².

Mechanism of Action

1. Antimalarial Mechanism Hydroxychloroquine and chloroquine work by interfering with the growth of parasites in the red blood cells. They increase the pH within intracellular vacuoles, disrupting the parasite’s ability to process and utilize hemoglobin¹.

2. Immunomodulatory Effects In autoimmune diseases, hydroxychloroquine modulates the immune response. It inhibits certain cellular processes, reducing inflammation and preventing tissue damage².

Medical Uses

1. Malaria Treatment and Prevention Both drugs are effective in treating and preventing malaria. They are particularly useful in regions where malaria remains sensitive to chloroquine³.

2. Rheumatoid Arthritis Hydroxychloroquine is used to manage rheumatoid arthritis by reducing inflammation and slowing disease progression².

3. Systemic Lupus Erythematosus (SLE) Hydroxychloroquine is also used to treat SLE, an autoimmune disease that affects various parts of the body².

Side Effects and Management

1. Common Side Effects Both drugs can cause side effects such as nausea, vomiting, and diarrhea. Long-term use may lead to more severe side effects like retinopathy².

2. Monitoring and Management Regular monitoring by healthcare providers is essential to manage side effects and ensure the safe use of these medications².
