RIFAXIMIN

Rifaximin, an antibiotic that is partly made in a laboratory has quickly become a medication in the field of therapy. It is mainly used to treat disorders related to the system and holds a prominent position in modern pharmacology.

In today's healthcare landscape, antibiotics play a role in the treatment of bacterial infections. They not only reduce illness but also significantly lower mortality rates. The emergence of antibiotics such as rifaximin has revolutionized the field of science.

This article aims to provide an overview of rifaximin. It covers aspects such, as its chemical makeup, how it works, approved and off-label uses recommended dosages, and important considerations related to side effects and potential interactions.

The main component in this medication is rifaximin while other ingredients include colloidal silicon dioxide, disodium edetate, and microcrystalline cellulose.

Rifaximin is mainly found in the form of tablets, which makes it easy to take and encourages patients to follow the treatment.

When compared to antibiotics rifaximin is absorbed very little by the body, which means it mainly works in a specific area. This special way that it behaves in the body makes it commonly used for treating problems related to the system.

Rifaximin works by blocking the synthesis of RNA. It attaches to the RNA polymerase, which is responsible for transcribing DNA into RNA, and interrupts this process. As a result, it hinders the growth of bacteria.

Regarding infections, rifaximin works effectively because it specifically targets and eliminates harmful bacteria without causing significant harm to the beneficial bacteria, in the gut.

Rifaximin is effective against a range of bacteria, including both Gram positive and Gram negative aerobic and anaerobic bacteria. This broad effectiveness makes it useful, for treating gastrointestinal conditions.

Rifaximin is a minimally absorbed antibiotic with high luminal activity, used to treat various gastrointestinal diseases. Although rifaximin has been proposed as first line treatment for small intestinal bacterial overgrowth (SIBO), few data are available regarding its efficacy in non-IBS subjects ¹. Rifaximin is almost completely non-absorbable, which means it stays in the intestines, having a local action and doesn’t cause systemic side effects, such as urinary tract infections ². ²: Antibiotics - SIBO - Small Intestinal Bacterial Overgrowth. Link ¹: Rifaximin for small intestinal bacterial overgrowth in non-IBS subjects: A prospective study. Link

Rifaximin is a non-absorbed antibiotic that has shown promise in treating individuals with recurrent Clostridium difficile infections, especially in cases where the primary treatment has not been effective ¹²³⁴⁵.
