The question, **is silvex an antibiotic?**, is complex because the name now also belongs to a modern, over-the-counter wound care product with antimicrobial properties [1.2.2].

According to a Pharmacy Times survey, Pepto-Bismol is the #1 pharmacist-recommended brand for upset stomachs. But what is the science behind the iconic pink liquid and **why does Pepto make me feel better** for a wide range of digestive issues? The answer lies in its unique, multi-symptom approach.

Cephamycins are a distinct class of $\beta$-lactam antibiotics that are closely related to cephalosporins, but their unique structure grants them enhanced stability against certain bacterial enzymes.

Less than 10% of conjunctivitis cases are bacterial, yet antibiotics are overprescribed for this common eye condition. This highlights a crucial misunderstanding: not all eye drops are antibiotics, and using the wrong type can be ineffective or even harmful.

In the battle against bacterial infections, antimicrobial agents are fundamentally categorized by their action: a **bactericidal agent** directly kills bacteria, as opposed to merely inhibiting their growth. This foundational distinction dictates their use in various clinical scenarios, particularly for severe infections where rapid pathogen eradication is necessary. The development and refinement of these potent substances have transformed modern medicine, offering critical tools for fighting a wide range of microbial threats.

Chlorhexidine (CHX) was first discovered in the 1950s as part of a research program for antimalarial agents but is now considered a gold-standard antiseptic in various medical and dental applications. This article explores the nuanced and concentration-dependent **mechanism of action of chlorhexidine** and its impact on a wide range of microorganisms.

Benzoyl peroxide is the only over-the-counter treatment that can completely clear acne. A 2.5% benzoyl peroxide gel is primarily used for the topical treatment of mild-to-moderate acne vulgaris, offering an effective and less irritating alternative to higher concentrations.

In clinical trials, colloidal bismuth subcitrate (CBS) has shown comparable efficacy to H2-receptor antagonists for healing peptic ulcers, with significantly lower relapse rates. This powerful therapeutic agent achieves its effects through a unique, multi-pronged approach that combines protective, healing, and antimicrobial actions in the gastrointestinal tract.

Povidone-iodine has been used as a trusted antiseptic and disinfectant for over 70 years, a significant improvement over earlier, more irritating iodine solutions. Understanding what is the mode of action of povidone provides insight into how this powerful antimicrobial agent effectively neutralizes pathogens on the skin and in wounds.
