Knowra Clindamycin Clindamycin Clindamycin is a lincosamide antibiotic that binds the bacterial 50S ribosomal subunit, inhibiting protein synthesis. It treats susceptible bacteria, including some anaerobes, but does not treat viral infections.
50S ribosomal subunit : The large subunit of bacterial ribosomes, where peptide bonds form and several antibiotics bind. Clindamycin binds this subunit and disrupts bacterial protein synthesis.
Clostridioides difficile infection : An intestinal infection caused by toxin-producing Clostridioides difficile, often following disruption of the gut microbiota. Clindamycin is a prominent risk factor for this infection because it can disrupt intestinal flora.
Lincosamide : A class of antibiotics that inhibits bacterial protein synthesis by binding the 50S ribosomal subunit. Clindamycin is the best-known member of this antibiotic class.
Vancomycin : A glycopeptide antibiotic that inhibits bacterial cell-wall synthesis and is used against serious gram-positive infections. Vancomycin offers a different mechanism and is often chosen when clindamycin resistance or intolerance rules it out.
Antibiotic-associated diarrhea : Loose or frequent stools arising during or after antibiotic treatment, caused by altered intestinal microbial communities or other effects. Clindamycin can cause diarrhea, including severe cases linked to C. difficile.
Protein synthesis inhibitor : A substance that impedes the production of proteins by disrupting translation or its supporting processes. Clindamycin belongs to this broad class of antibacterial drugs.
Bacterial vaginosis : A vaginal condition involving a shift from lactobacillus-dominant flora to a diverse anaerobic bacterial community. Clindamycin is one treatment option, given orally or as a vaginal preparation.
Anaerobic bacteria : Bacteria that grow without oxygen; some tolerate oxygen, while others are harmed by it. Clindamycin covers many anaerobes, but susceptibility varies by species and location.
Metronidazole : An antimicrobial drug that damages DNA in susceptible anaerobic bacteria and certain protozoa. Metronidazole is an alternative for many anaerobic infections, with a distinct mechanism and spectrum.
Antibiotic stewardship : Practices that improve antimicrobial selection, dosing, and duration to preserve effectiveness and reduce harm. Stewardship limits unnecessary clindamycin exposure because of its resistance and colitis risks.
