Which of the following drugs is found to be effective in worm infections like Ascariasis?

Appeared in: Raj. CHO - 2023

Explanation

  • Albendazole is a broad-spectrum anthelmintic (anti-worm) drug, making it the appropriate choice for treating infections caused by worms like Ascaris lumbricoides.
  • Its mechanism of action involves inhibiting microtubule synthesis within the parasite, which disrupts essential functions like glucose uptake, leading to the worm's death.
  • It is listed as a first-choice drug for Ascariasis, often requiring only a single 400 mg dose for effective treatment.

Why Other Options Were Wrong

  • Option A: Rabeprazole is a proton pump inhibitor (PPI) used to decrease stomach acid production.
  • Option B: Allopurinol is a xanthine oxidase inhibitor used to reduce the production of uric acid in the body.
  • Option D: Fluconazole is an antifungal medication belonging to the azole class.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Pharmacological treatment of helminthic infections (Ascariasis) as background academic context rather than a clinical decision trigger.
  • A key nursing role is patient education on hygiene to break the cycle of reinfection. This includes proper handwashing, safe food preparation, and sanitation.
  • When administering Albendazole, instructing the patient to take it with a fatty meal can increase its systemic absorption, which is crucial for treating tissue-dwelling parasites, though less critical for purely intestinal worms.
  • Nurses in community health settings may participate in mass drug administration (MDA) programs, where Albendazole is given periodically to at-risk populations (like schoolchildren) to control worm burden and associated malnutrition.
How to Approach the Question
  • First, identify the core of the question. It asks for a drug to treat a specific type of 'worm infection' (Ascariasis). This means you are looking for an anthelmintic drug.
  • Next, evaluate each option based on its drug class and primary use.
  • Option A, Rabeprazole, is a PPI for acid reflux.
  • Option B, Allopurinol, is for gout.
  • Option D, Fluconazole, is an antifungal.
  • Option C, Albendazole, is a known broad-spectrum anthelmintic.
Concept Tested & Keywords
