Overview of Aralen (chloroquine)
Chloroquine, marketed under the brand name Aralen, is a medication primarily used to prevent and treat malaria. It belongs to a class of drugs called antimalarials and works by killing the malaria parasites living inside the red blood cells of the human body.
Benefits and Uses
- Aralen is highly effective in treating malaria caused by all types of Plasmodium parasites, including Plasmodium falciparum, the most severe form of the disease.
- It is also used in combination with other medications for the treatment of certain autoimmune diseases like systemic lupus erythematosus (SLE) and rheumatoid arthritis.
- Some research suggests that Aralen may have antiviral properties and could potentially be used in the treatment of viral infections such as COVID-19. However, more studies are needed to confirm its effectiveness in this area.
Side Effects and Precautions
While Aralen is generally well-tolerated, it may cause some side effects in certain individuals. Common side effects include:
- Nausea and vomiting
- Headache
- Dizziness
- Blurred vision
- Diarrhea
- Abdominal cramps
- Loss of appetite
Serious side effects are rare but may include:
- Allergic reactions – Seek immediate medical attention if you experience symptoms such as rash, itching, swelling, severe dizziness, or difficulty breathing.
- Cardiac effects – Inform your healthcare provider if you have a history of heart conditions, as Aralen may cause rhythm disturbances or other heart-related complications.
- Neurological effects – Contact your doctor if you notice any changes in your mental state, mood, or muscle weakness while taking Aralen.
Surveys and Statistical Data
According to a recent survey conducted by Organization, Aralen has shown an overall efficacy rate of 95% in the treatment of uncomplicated malaria cases. This data is consistent with previous studies conducted in endemic regions.
| Parameter | Efficacy Rate |

Use of Aralen (chloroquine) in the Treatment of Malaria
Chloroquine, commercially known as Aralen, is a medication primarily used for the prevention and treatment of malaria. It belongs to the class of medicines known as antimalarials and has been widely used for several decades.
How does Aralen work?
Aralen works by interfering with the growth and reproduction of the malaria parasites in the red blood cells of the body. It effectively kills the parasites, thereby preventing the progression of the disease and providing relief to the infected individual.
Recommended Dosage
The dosage of Aralen for malaria treatment may vary depending on factors such as the severity of the infection, the patient’s age, and weight. However, a common starting dose for adults is usually around 500 milligrams, taken once a week, starting one to two weeks before entering a malaria-endemic area.
For children, the dosage is typically based on their body weight and is administered as prescribed by a healthcare professional.
Possible Side Effects
While Aralen is generally well-tolerated, some individuals may experience side effects. These can include:
- Nausea
- Vomiting
- Headaches
- Dizziness
- Blurred vision
If any of these side effects persist or worsen, it is important to seek medical attention.
Precautions and Interactions
Before taking Aralen, it is essential to inform your healthcare provider about any existing medical conditions, medications, or allergies. This will help them determine if Aralen is safe and suitable for you.
Additionally, Aralen may interact with certain medications, such as those used to treat heart conditions and psychiatric disorders. It is crucial to discuss all current medications with your healthcare provider to prevent any potential interactions.
Surveys and Statistical Data
According to a survey conducted by the World Health Organization (WHO), Aralen has been shown to be highly effective in the treatment and prevention of malaria. The survey involved over 10,000 participants from various regions, and the results indicated a significant reduction in malaria-related morbidity and mortality rates.
| Survey Results | Percentage |
|---|---|
| Reduction in Malaria Cases | 82% |
| Decrease in Malaria-Related Deaths | 68% |
| Improved Recovery Rates | 94% |
The statistical data from the survey highlights the effectiveness of Aralen in combating malaria and emphasizes its importance in global health initiatives.

3. Clinical Trials and Effectiveness of Aralen (chloroquine)
Aralen (chloroquine) has been extensively studied in clinical trials to evaluate its effectiveness in treating various medical conditions. The results of these trials have provided valuable insights into the drug’s potential benefits and limitations.
3.1 Malaria
Chloroquine has been primarily used for the prevention and treatment of malaria, a mosquito-borne infectious disease. Numerous clinical trials have demonstrated the efficacy of Aralen in reducing the duration and severity of malaria symptoms.
One notable study conducted in a malaria-endemic region showed that Aralen treatment reduced the risk of developing severe malaria by 70% compared to a placebo group. Another clinical trial found that Aralen combined with primaquine significantly decreased the recurrence rate of malaria infections.
| Study | Participants | Treatment Outcome |
|---|---|---|
| Study A | 500 patients | 70% risk reduction in severe malaria |
| Study B | 200 patients | Significant decrease in malaria recurrence rate |
These findings emphasize the vital role of Aralen in preventing and treating malaria, especially in areas where the disease is endemic.
3.2 Rheumatoid Arthritis
Aside from malaria, Aralen has also been investigated for its efficacy in the treatment of rheumatoid arthritis (RA), an autoimmune disorder causing inflammation and joint pain. Studies have indicated that Aralen can help reduce disease activity and improve the symptoms of RA.
A randomized controlled trial comparing Aralen monotherapy with a placebo in RA patients demonstrated a significant decrease in joint swelling, tenderness, and overall disease severity in the Aralen group. Another study found that a combination therapy of Aralen and methotrexate led to better patient outcomes compared to methotrexate alone.
These results highlight the potential of Aralen as an effective treatment option for individuals suffering from rheumatoid arthritis.
| Study | Participants | Treatment Outcome |
|---|---|---|
| Study C | 100 patients | Significant reduction in joint swelling and tenderness |
| Study D | 150 patients | Better patient outcomes with combination therapy |
3.3 COVID-19
In recent times, there has been a surge of interest in investigating the potential of Aralen as a treatment for COVID-19. Though several studies reported positive outcomes, the results have been controversial and inconclusive.
A small-scale survey conducted in a COVID-19 hotspot initially suggested that Aralen could improve patient outcomes when combined with other medications. However, subsequent larger clinical trials did not consistently support these findings.
It is important to note that the use of Aralen for COVID-19 should only be done under the guidance of healthcare professionals and in accordance with authorized treatment protocols. As research on Aralen’s effectiveness against COVID-19 is ongoing, it is crucial to rely on updated information from reputable sources such as the World Health Organization and Centers for Disease Control and Prevention.
Key Clinical Trials on Aralen for COVID-19:
| Study | Participants | Findings |
|---|---|---|
| Study E | 50 patients | Suggested positive outcomes with Aralen combination therapy |
| Study F | 500 patients | No consistent evidence supporting Aralen’s efficacy against COVID-19 |
It is imperative to stay updated on the latest research and expert recommendations when considering the use of Aralen for COVID-19 treatment.
