Introduction to Aralen (Chloroquine) – Benefits, Uses, and Side Effects

Introduction to Aralen (Chloroquine)

Aralen, also known as Chloroquine, is a medication that has been used for several decades to prevent and treat malaria. It belongs to a class of drugs called antimalarials, which work by killing the parasites that cause the disease.

Malaria is a life-threatening mosquito-borne disease that affects millions of people worldwide, particularly in tropical and subtropical regions. It is caused by parasites from the Plasmodium family, which are transmitted to humans through the bites of infected mosquitoes.

The use of Aralen has been studied extensively and has proven to be effective in treating uncomplicated malaria caused by Plasmodium vivax, Plasmodium malariae, Plasmodium ovale, and some strains of Plasmodium falciparum. However, it may not be effective against strains of malaria that are resistant to chloroquine.

Mechanism of Action

Chloroquine works by interfering with the parasite’s ability to break down and utilize hemoglobin, a protein found in red blood cells. It accumulates within the parasite and disrupts the process of heme polymerization, leading to the accumulation of toxic heme molecules. These toxic molecules ultimately kill the parasite.

“Chloroquine accumulates in the food vacuole of the parasite. It inhibits plasmodial heme polymerase and acts by concentrating within parasite acid-vesicles where it becomes protonated and concentrated 500-fold higher than in the plasma.” – Source

Usage and Dosage

Aralen usually comes in tablet form, and the dosage prescribed by healthcare professionals may vary depending on factors such as the patient’s age, weight, and the severity of the malaria infection.

It is important to follow the prescribed dosage and complete the full course of treatment, even if symptoms improve, to ensure the complete elimination of the parasite and prevent a relapse. Failure to do so may result in the development of drug-resistant strains of malaria.

Possible Side Effects

As with any medication, Aralen may cause side effects in some individuals. Common side effects may include headache, dizziness, nausea, vomiting, and diarrhea. These side effects are usually mild and go away on their own. However, if any severe or persistent side effects occur, it is important to seek medical attention immediately.

It is also worth noting that Aralen can interact with certain medications, such as blood thinners and medications used to treat heart conditions. Therefore, it is important to inform your healthcare provider about all the medications you are currently taking.

Conclusion

Aralen, or Chloroquine, is a well-established and effective medication for the treatment and prevention of malaria. Its mechanism of action in targeting the parasites that cause the disease has made it a valuable tool in the fight against malaria in many parts of the world.

“Chloroquine has been used for decades in the prevention and treatment of malaria. It is cost-effective, readily available, and has a low rate of resistance when used appropriately. It plays a crucial role in malaria control efforts, especially in regions where access to healthcare facilities and other antimalarial drugs may be limited.” – World Health Organization
