Globally, an estimated 1.5 billion people, or 24% of the world's population, are infected with soil-transmitted helminths alone [1.8.2]. This raises the question: what antibiotics are used to treat parasitic infections, and how do they work?

First introduced for medical use in 1960, the active ingredient in Metrogyl, metronidazole, has become a mainstay for treating anaerobic bacterial infections and protozoal parasites. Metrogyl’s effectiveness against microscopic organisms makes it a critical tool in clinical pharmacology. If you're wondering what parasites does METROGYL treat, the list includes some of the most common protozoal pathogens affecting humans worldwide.

Over 2 million prescriptions for metronidazole were filled in the U.S. in 2023, highlighting its widespread use against specific infections. While it's a powerful antibiotic, its spectrum is surprisingly limited, raising the question: what bacteria does metronidazole get rid of? This article explores its selective action against obligate anaerobic bacteria and certain protozoal parasites.

Ponazuril is often confused with traditional dewormers, but it is actually a powerful anti-protozoal medication. As a result, it does not treat worms at all but is highly effective against single-celled parasitic organisms like Coccidia and *Sarcocystis neurona*.

Ponazuril, also known as toltrazuril sulfone, is a major active metabolite of the drug toltrazuril, a key fact distinguishing these two widely used veterinary antiparasitic medications. This fundamental relationship leads to significant differences in their formulation, pharmacokinetics, approved uses across species, and overall clinical application.

Millions of pets are affected by intestinal parasites annually, but not all parasites respond to the same medication. A common question from owners is: **Does Panacur treat coccidia?** The answer is that Panacur is ineffective against this protozoan infection and different medications are required for proper treatment.

First approved for use in the United States in 2004, the antimicrobial drug tinidazole is prescribed for several key parasitic and bacterial infections. It is a second-generation nitroimidazole, similar to metronidazole, that acts by damaging the DNA of the infectious organism, leading to its death.

Metronidazole has been a cornerstone treatment for various infections since the 1960s, a testament to its unique and effective mechanism. To understand its power, one must delve into the biochemical process that explains how does metronidazole work to selectively target harmful microbes while leaving host cells largely unharmed. This powerful medicine is actually a prodrug, meaning it must be activated inside the pathogen to become a toxic agent.
