| Specification |
Appearance: White to off-white crystalline powder Assay: ≥ 98% (API standard) Solubility: More soluble in water compared to albendazole sulfoxide (free base), due to hydrochloride salt form Common dosage forms: Veterinary oral suspensions, bolus, injectable formulations |
| Pharmacodynamic Properties |
Mode of Action: Active metabolite of albendazole; binds to β-tubulin in parasites, inhibiting microtubule formation and glucose uptake → energy depletion → parasite death. Spectrum: Broad-spectrum activity against gastrointestinal nematodes, lungworms, tapeworms, and liver flukes (larval and adult stages). Key Features: Hydrochloride salt form improves solubility and absorption compared to base compound Maintains strong systemic activity as the main active metabolite of albendazole Effective in both ruminants and non-ruminant species In short: Albendazole Sulphoxide Hydrochloride (Ricobendazole HCl) is a soluble active metabolite of albendazole that kills parasites by disrupting microtubules and starving them of energy, with broad-spectrum efficacy. |
