Summary Chapter 3.12 Aminoglycosides

Chapter 3.12 covers aminoglycosides, a potent broad-spectrum antibiotic class that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit. Commonly used for severe infections like streptococcal endocarditis, they are administered intravenously or intramuscularly. Major concerns include nephrotoxicity, ototoxicity, and neurotoxicity, requiring close monitoring of renal function, hearing, and nerve damage.
