Wormentel 150mg

What is Wormentel 150 mg?

Wormentel 150 mg is an anthelmintic medication that contains Fenbendazole as an active agent. Fenbendazole belongs to the benzimidazole class of compounds and is a broad spectrum agent. It is highly effective against various parasitic worm infections affecting animals. Wormentel 150 mg tablets come in chewable formulation for easier administration that provides patient compliance.

Key Features

How does Wormentel 150 mg work?

The mode of action of Fenbendazole consists of an inhibition of microtubule synthesis in parasites. It binds to β-tubulin of the parasite, preventing its polymerization into microtubules. This disrupts cell division and structure, impairing glucose uptake and other vital processes, leading to the death of the worm. This is selectively toxic to parasites because helminthic β-tubulin has a higher affinity for the drug compared to mammalian tubulin.

Uses

Wormentel 150 mg is used for the treatment of several types of Intestinal parasitic infections like:

• Ascariasis (roundworm infections)
• Enterobiasis (pinworm infections)
• Hookworm infections
• Trichuriasis (whipworm infections)
• Hydatid disease
• Neurocysticercosis

Dosage

Wormentel 150 mg dosage can vary depending on the condition being targeted, animal factors, and medication form. The following are some guidelines on general dosing:

Route of administration: For oral administration only

Standard dosage:

Sheep & Goat: 5 mg/kg body weight as a single dose

Cattle & Horse: 7.5 mg/kg body weight as a single dose

Dog & Cat: 100 mg/kg weight as a single dose

Side effects

• Abdominal pain
• Nausea
• Vomiting
• Diarrhea
• Headache
• Light headedness
• Fever

Interaction

• Cimetidine, dexamethasone, and praziquantel enhance plasma levels of Fenbendazole sulfoxide (active metabolite)
• Antacids can reduce absorption
• Carbamazepine and phenytoin may reduce efficacy

Pharmacokinetics

• Fenbendazole is poorly absorbed, absorption increases with fatty meals.
• It undergoes rapid first-pass metabolism to active metabolite Fenbendazole sulfoxide.
• Peak plasma levels reach within 2-5 hours. Half-life is 8-12 hours.
• Excreted mainly in feces.

Precautions

• Contraindicated in pregnancy (Category C) and hypersensitivity
• Caution in animals with liver disease and lactation
• Monitor the liver enzymes profile in animals with prolonged use
• It should not be used for animal infants less than 3 months of age

Safety Profile

• Common adverse events: mild gastrointestinal upset (nausea, vomiting, diarrhea), headache, dizziness.
• Less common but important side effects: liver enzyme elevation, bone‑marrow suppression, allergic reactions.
• Long‑term or high‑dose safety unknown; monitoring recommended for liver function.

Efficacy Evidence

• Established antiparasitic activity: effective against roundworms, hookworms, whipworms, pinworms in observational use.
• No approved indication for cancer or other non‑parasitic conditions.
• Pre‑clinical studies (cell lines & animal models) report anti‑proliferative effects via microtubule disruption, glucose‑uptake inhibition, apoptosis induction.

Conclusion

Wormentel 150 mg tablet is an efficacious single-dose therapy for common intestinal parasitic infections and is well-tolerated when used appropriately. It is a reliable, single‑dose anthelmintic for common intestinal helminths with a favorable short‑term safety record. Its role beyond parasitology (e.g., oncology) remains experimental, rigorous clinical trials are essential to define safety, dosing, and therapeutic benefit in those contexts. Use only under physician guidance, especially for off‑label purposes.
