Generic Aralen Information

Introduction

Aralen is a medication that contains the active compound chloroquine. It belongs to the groups of antiviral, antimalarial (antiparasitic) and has been evaluated for potential use against COVID‑19. In Hong Kong it is mainly prescribed for the prevention and treatment of malaria, as well as for certain autoimmune disorders when used off‑label. Chloroquine was originally developed by the pharmaceutical company Novartis (formerly Sandoz) under the brand name Aralen, and generic formulations are now widely available worldwide.

What is Aralen?

Aralen is a solid oral tablet that delivers chloroquine phosphate. It is classified as an antimalarial agent within the 4‑aminoquinoline class. The drug was first synthesized in the 193s and received widespread use for malaria prophylaxis and therapy. Although newer antimalarials have largely replaced chloroquine in regions with resistant parasites, the medication retains specific indications and is retained in many national formularies, including Hong Kong’s Hospital Authority Drug Formulary.

While Aralen itself is a brand name, the same active ingredient is marketed under other well‑known names such as Plaquenil (hydroxychloroquine, a related compound) and older trademarks like Resochin. Generic chloroquine tablets are chemically identical and are offered at a lower price point, making them a cost‑effective option for patients who require long‑term therapy.

How Aralen Works

Chloroquine interferes with the growth of intracellular parasites and viruses by several mechanisms:

• Lysosomal alkalinisation – The drug accumulates in acidic vesicles (e.g., malaria parasite’s food vacuole) and raises the pH, inhibiting haemoglobin digestion and detoxification of heme, which is toxic to the parasite.
• Inhibition of viral entry and replication – For certain viruses, including early studies on SARS‑CoV‑2, chloroquine blocks the glycosylation of cellular receptors and hampers endosomal fusion, thereby reducing viral entry into host cells.
• Immunomodulatory effects – Chloroquine reduces the production of pro‑inflammatory cytokines (e.g., IL‑6, TNF‑α) and interferes with antigen presentation, which explains its off‑label use in rheumatic diseases.

After oral administration, chloroquine is rapidly absorbed, with peak plasma concentrations reached within 2–4 hours. It distributes extensively into tissues, especially melanin‑rich organs (skin, retina), and has a long elimination half‑life of 1–2 months due to deep tissue sequestration. This pharmacokinetic profile underlies both its therapeutic efficacy and the need for careful dosing to avoid accumulation‑related toxicity.

Conditions Treated with Aralen

• Uncomplicated malaria (Plasmodium vivax, P. ovale, chloroquine‑sensitive P. falciparum) – Used for both treatment and prophylaxis in travelers to endemic areas.
• Rheumatoid arthritis and systemic lupus erythematosus (off‑label) – The immunomodulatory properties help control disease activity.
• COVID‑19 (investigational) – Early in the pandemic chloroquine was assessed for antiviral activity; current guidelines in Hong Kong reserve its use for clinical trials only.

In Hong Kong, malaria is rare, but imported cases from Southeast Asia and Africa are reported each year. The local health authority maintains chloroquine as a reserve antimalarial for regions where sensitivity is confirmed. Autoimmune conditions are common indications for chloroquine‑based therapies, especially when patients cannot tolerate newer disease‑modifying drugs.

Patient Groups Most Likely to Benefit

• Travelers to chloroquine‑sensitive malaria zones – Individuals planning short‑term trips to Central America, the Middle East, or parts of Asia where P. vivax predominates.
• Patients with mild‑to‑moderate rheumatoid arthritis or lupus who require a steroid‑sparing agent and have normal baseline ocular examinations.
• Participants in controlled clinical trials for COVID‑19 where chloroquine is being evaluated under strict protocol.

Contra‑indications or cautionary use include: patients with known retinal disease, significant cardiac conduction disorders, severe hepatic or renal impairment, and pregnant or lactating women (unless benefits outweigh risks). Genetic variations affecting cytochrome P450 2D6 activity are more common in Asian populations and may alter drug metabolism, necessitating closer monitoring.

Risks, Side Effects, and Interactions

Common

• Nausea, vomiting, and abdominal discomfort
• Headache and dizziness
• Pruritus (skin itching)

Rare

• Cutaneous hyperpigmentation (especially with prolonged therapy)
• Mood changes, including mild depression or anxiety
• Elevated liver enzymes

Serious

• Retinopathy – Progressive retinal pigment epithelium changes leading to irreversible vision loss; risk increases after cumulative doses > 100 g.
• Cardiac toxicity – QT‑interval prolongation, ventricular arrhythmias, especially when combined with other QT‑prolonging agents.
• Severe hypoglycaemia – Enhanced insulin activity, notable in diabetic patients.
• Hematologic effects – Aplastic anemia, agranulocytosis (very rare).

Clinically Relevant Drug–Drug Interactions

• Antibiotics: Macrolides (e.g., azithromycin) and fluoroquinolones may potentiate QT prolongation.
• Antiretrovirals: Protease inhibitors (ritonavir) can increase chloroquine plasma levels via CYP3A4 inhibition.
• Antidiabetic agents: Sulfonylureas and insulin may cause synergistic hypoglycaemia.
• Anticoagulants: Warfarin metabolism can be altered, requiring INR monitoring.

Patients should disclose all concurrent medications, including over‑the‑counter products and herbal supplements (e.g., St. John’s wort), to their healthcare provider.

Practical Use: Dosing, Missed Dose, Overdose

• Adult prophylaxis for malaria: 300 mg chloroquine phosphate (equivalent to 250 mg base) once weekly, starting 1‑2 weeks before travel and continuing for 4 weeks after return.
• Adult treatment of uncomplicated malaria: 1 g (≈ 830 mg base) orally on day 1, followed by 500 mg on days 2 and 3.
• Rheumatic disease (off‑label): 250 mg daily, titrated based on response and ocular monitoring.

Missed dose: If a weekly prophylactic dose is missed, take it as soon as remembered unless the next scheduled dose is within 24 hours; then skip the missed dose and continue the regular schedule. Do not double‑dose.

Overdose: Symptoms may include seizures, severe cardiac arrhythmias, and profound hypotension. Immediate medical attention is essential. Gastric lavage and activated charcoal are recommended if presentation is within one hour of ingestion. Intravenous artesunate is not effective against chloroquine toxicity; treatment focuses on supportive care and cardiac monitoring.

Precautions:

• Take tablets with a full glass of water; food may reduce gastrointestinal upset.
• Avoid alcohol, which can increase the risk of hypoglycaemia and cardiac effects.
• Patients with hepatic or renal insufficiency require dose adjustment and close laboratory surveillance.
