, Drugs that inhibit bacterial synthesis of DNA and RNA, or disrupt DNA
function
Anti-metabolites
Drugs that suppress viral replication
Drugs that inhibit cell wall synthesis - 🧠ANSWER ✔✔Penicillins and
cephalosporins
Weaken cell wall, hence promote bacterial lysis and death
Drugs that increase cell membrane permeability - 🧠ANSWER
✔✔Amphotericin B
Increase the permeability of cell membranes causing leakage of
intracellular material
Drugs that cause lethal inhibition of bacterial protein synthesis -
🧠ANSWER ✔✔Aminoglycosides; gentamicin
Drugs that cause non-lethal inhibition of protein synthesis - 🧠ANSWER
✔✔Tetracyclines
Inhibit bacterial protein synthesis, and only slow microbial growth, but do
not kill the bacteria at clinically achievable concentrations
