1. Basic Product Identification
Albendazole
INN Name: Albendazole
Therapeutic Class: Anthelmintic (anti-parasitic)
Pharmacological Class: Benzimidazole derivative
ATC Code: P02CA03
Dosage Forms: Tablets, chewable Andorra tablets, oral suspension
Primary Use: Treatment of parasitic worm infections
2. Therapeutic Knowledge
Albendazole is used for broad-spectrum parasitic infections:
Intestinal helminths:
Ascaris lumbricoides
Hookworm (Ancylostoma, Necator)
Whipworm (Trichuris trichiura)
Enterobius (pinworm)
Tissue parasites:
Neurocysticercosis (Taenia solium larvae)
Hydatid disease (Echinococcus granulosus)
???? Key advantage:
Broad-spectrum + tissue penetration activity
3. Mechanism of Action (MOA)
Albendazole works by targeting parasite energy metabolism:
Binds to β-tubulin in parasites
Inhibits microtubule polymerization
Blocks glucose uptake
Depletes glycogen stores
???? Result:
Parasite immobilization → energy starvation → death
4. Pharmacokinetics (ADME)
Absorption: Poor oral absorption (~5%) → improved with fatty meals
Bioavailability: Increased with high-fat food
Prodrug conversion: Albendazole → Albendazole sulfoxide (active metabolite)
Distribution: Wide, including CNS (important for neurocysticercosis)
Metabolism: Hepatic (CYP3A4)
Half-life: ~8–12 hours (metabolite)
Excretion: Urine (metabolites), bile
5. Dosage & Administration
Adults & children (>2 years):
Intestinal worms:
400 mg single dose or 3-day regimen
Neurocysticercosis:
15 mg/kg/day (max 800 mg/day) for 8–28 days
