Generic Albendazole Information

Introduction

Albendazole is a broad‑spectrum antiparasitic medication widely used to treat a variety of helminthic infections. In Hong Kong, the drug is prescribed for both common community‑acquired parasitic diseases and for infections that may be imported through travel. The active compound, albendazole, belongs to the benzimidazole class of anthelmintics. It is manufactured by several global pharmaceutical firms, most notably Pfizer under the brand name Albenza®; generic versions are available at a lower cost. Besides its primary role in eradicating intestinal worms, albendazole is employed for tissue‑invasive parasites such as echinococcosis and neurocysticercosis, conditions that can have serious neurological sequelae if untreated.

What is Albendazole?

Albendazole is the generic version of Albenza®, containing the same active compound Albendazole. It is an oral antiparasitic agent classified as a benzimidazole derivative. First synthesized in the 197s by the pharmaceutical company Johnson & Johnson, albendazole has since been licensed worldwide and is listed on the World Health Organization’s Model List of Essential Medicines. In Hong Kong, it is supplied by domestic distributors and can be imported under a doctor’s prescription. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, delivering the same therapeutic effect as the branded product while reducing the financial burden on patients.

How Albendazole Works

Albendazole exerts its antiparasitic effect by binding to β‑tubulin of helminths, thereby inhibiting microtubule polymerisation. Microtubules are essential for glucose uptake and intracellular transport in parasites. Disruption of this process leads to depletion of parasite glycogen stores, impaired metabolism, and ultimately parasite death. After oral administration, albendazole is rapidly absorbed, but its bioavailability is enhanced when taken with a fatty meal because the drug is lipophilic. Hepatic cytochrome P450 enzymes (primarily CYP3A4) convert albendazole to the active metabolite albendazole sulfoxide, which attains systemic concentrations sufficient to treat tissue‑invasive parasites. The onset of therapeutic action usually occurs within 24 hours for intestinal nematodes, while treatment of cystic lesions may require several weeks of therapy to achieve complete parasite clearance.

Conditions Treated with Albendazole

• Intestinal nematodes – Ascaris lumbricoides, Enterobius vermicularis, Trichuris trichiura, and hookworms (Ancylostoma duodenale, Necator americanus). These infections remain prevalent in Hong Kong’s peri‑urban areas and among travelers returning from endemic regions.
• Tissue‑invasive helminths – Cystic echinococcosis (hydatid disease) caused by Echinococcus granulosus and alveolar echinococcosis (E. multilocularis). Albendazole is the first‑line medical therapy, often in conjunction with surgical intervention.
• Neurocysticercosis – Central nervous system infection by Taenia solium larvae. Prolonged albendazole courses (often 8–12 weeks) reduce viable cyst burden and alleviate seizures.
• Giardiasis and other protozoal infections – While not the primary indication, albendazole has demonstrated activity against Giardia lamblia and certain Trichomonas species.

Epidemiological data from the Hong Kong Centre for Health Protection indicate that intestinal helminth infections affect up to 6 % of school‑age children, and cases of neurocysticercosis, though rare, have risen with increased global migration. Albendazole’s broad spectrum makes it a valuable tool for clinicians addressing these public‑health concerns.

Patient Groups Most Likely to Benefit

• Children and adolescents with confirmed or suspected intestinal worm infestations, especially those attending schools in districts with limited sanitation.
• Pregnant women in the second and third trimesters requiring treatment for echinococcosis, where surgical options are contraindicated. (First‑trimester exposure is generally avoided due to limited safety data.)
• Immunocompromised individuals (e.g., transplant recipients, HIV‑positive patients) who are at higher risk for disseminated parasitic disease.
• Travelers returning from endemic regions (Southeast Asia, Middle East, Africa, South America) who present with gastrointestinal or neurological symptoms suggestive of helminth infection.

Contra‑indications include known hypersensitivity to benzimidazoles, severe hepatic impairment, and, for prolonged high‑dose regimens, pregnancy in the first trimester. Clinicians must assess liver function before initiating therapy and monitor throughout treatment.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal disturbances – Nausea, abdominal pain, and transient diarrhoea are reported in up to 10 % of patients.
• Transient elevation of liver enzymes – Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) may rise modestly; routine monitoring is advised for courses longer than three weeks.
• Headache and dizziness – Usually mild and self‑limiting.

Rare

• Hair loss (alopecia) – Documented in isolated case reports during prolonged therapy (≥6 months).
• Leukopenia or neutropenia – Occurs infrequently; complete blood count should be checked in patients receiving extended treatment.

Serious

• Severe hepatotoxicity – Rare but potentially fatal liver injury has been described, particularly with high‑dose regimens for echinococcosis. Prompt discontinuation and supportive care are required.
• Bone marrow suppression – Pancytopenia may develop, mandating immediate cessation of the drug and hematology consultation.
• Hypersensitivity reactions – Anaphylaxis or severe skin rash (Stevens‑Johnson syndrome) warrant emergency treatment.

Clinically Relevant Drug‑Drug Interactions

• CYP3A4 inducers (e.g., rifampicin, carbamazepine, St. John’s wort) reduce albendazole plasma levels, potentially compromising efficacy.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin) may increase albendazole sulfoxide concentrations, heightening the risk of hepatotoxicity.
• Warfarin – Albendazole can potentiate anticoagulant effects; INR monitoring is recommended.
• Antiepileptic drugs – Concomitant use with phenytoin may alter seizure thresholds; clinical judgement is required.

Patients should disclose all medications, herbal supplements, and over‑the‑counter products to their prescriber before initiating albendazole.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing for most intestinal nematodes: 400 mg orally once daily for 3 days.
• Echinococcosis: 400 mg twice daily for 28 days, followed by a drug‑free interval; cycles are repeated up to three times depending on imaging response.
• Neurocysticercosis: 400 mg twice daily for 8–12 weeks, often combined with steroids to reduce inflammatory reactions.

Administration tips – Take tablets whole with a meal containing fat (e.g., milk, yogurt) to maximise absorption. Swallow with water; crushing may diminish efficacy.

Missed dose – If a dose is missed within 12 hours, take it as soon as remembered. If it is close to the time of the next scheduled dose, skip the missed dose and continue the regular schedule; do not double‑dose.

Overdose – Acute overdose is uncommon but may present with nausea, vomiting, abdominal pain, and transient hepatic enzyme elevation. Management is supportive: gastric lavage if presentation is within one hour, activated charcoal, and monitoring of liver function. No specific antidote exists. Seek immediate medical attention.

Precautions – Patients with pre‑existing liver disease should have baseline liver function tests and periodic monitoring. Alcohol consumption should be limited during therapy to reduce hepatic stress. Pregnant women must confirm gestational age before therapy; breastfeeding is generally not recommended while on albendazole.
