IV. Dosing: General

  1. Take capsules with water to prevent esophageal irritation
  2. May take with or without food
  3. Reduce dose in hepatic dysfunction

V. Dosing: Adult

  1. Oral
    1. Moderate infections: 300 to 450 mg orally three to four times daily
    2. Severe or complicated infections: 600 mg orally three times daily
  2. IV: 600 to 900 mg IV every 8 hours
  3. IM: up to 600 mg every 8 hours

VI. Dosing: Child

  1. Preterm Infant
    1. IV: 15 mg/kg/day IV divided three times daily
  2. Term Infants < 1 month
    1. IV: 15 to 20 mg/kg/day IV divided three times daily
  3. Child
    1. IV: 20 to 40 mg/kg/day IV divided every 6 to 8 hours
    2. PO: 8 to 20 mg/kg/day orally divided three to four times daily

VII. Pharmacokinetics

  1. Both renal and hepatic excretion
  2. Actively transported into abscesses
  3. Does not enter cerebrospinal fluid

VIII. Adverse Effects

  1. Abdominal cramping
  2. Diarrhea
  3. Pseudomembranous colitis (Clostridioides difficile)
    1. Although most systemic Antibiotics risk C. diff, Clindamycin has been most associated

IX. Safety

  1. Considered safe in pregnancy
  2. Considered safe in Lactation

X. Drug Interactions

  1. CYP3A4 Inducers
    1. Decrease Clindamycin serum levels

Definition (CHV) an antibacterial drug
Definition (CHV) an antibacterial drug
Definition (NCI) A semisynthetic broad spectrum antibiotic produced by chemical modification of the parent compound lincomycin. Clindamycin dissociates peptidyl-tRNA from the bacterial ribosome, thereby disrupting bacterial protein synthesis. (NCI04)
Definition (MSH) An antibacterial agent that is a semisynthetic analog of LINCOMYCIN.

Ontology: Lincosamide Antibiotic (C2826567)

Definition (NCI) Any synthetic or semi-synthetic derivative of lincomycin, first isolated from a soil actinomycete Streptomyces lincolnensis, with antibacterial activity. Lincosamide antibiotics bind to the 23S rRNA in the large 50S subunit of bacterial ribosomes, thereby preventing the peptidyl-tRNA translocation from the A site to the P site. This results in peptidyl-tRNA dissociation from ribosomes, and leads to the release of incomplete proteins, ultimately causing cell death.
