| Term | Definition |
| Sulphonamide | inhibit nucleic acid synthesis; inhibit dihydrofolate synthestase (inhibiting folate production, required for DNA replication); bacteriostatic, most well absorbed from gut, cojugated by liver |
| Trimethoprim | inhibit nucleic acid synthesis; inhibits dihydrofolate reductase (inhibiting folate production, required for DNA replication) |
| Co-trimoxazole | mixture of trimethorprim and sulphamethoxazole (a sulphonamide); rapidly absorbed from GIT, excreted in urine, excreted by urine |
| Penicillin | B-lactam; Inhibits cell wall synthesis (preventing cross-linkage between peptidoglycan chains) e.g. amoxycillin |
| Cephalosporin | B-lactam; Inhibits cell wall synthesis (preventing cross-linkage between peptidoglycan chains) e.g. cephalexin |
| carbapenem | B-lactam; Inhibits cell wall synthesis (preventing cross-linkage between peptidoglycan chains) e.g. imipenem |
| monobactam | B-lactam; Inhibits cell wall synthesis (preventing cross-linkage between peptidoglycan chains) e.g. aztreonam |
| vancomycin | inhibits cell wall synthesis; inhibits peptidoglycan formation |
| aminoglycoside | inhibits protein synthesis; binds to 30S subunit and inhibits binding of aminoacyl-tRNA |
| tetracycline | inhibits protein synthesis; binds to 30S subunit and inhibits binding of aminoacyl-tRNA |
| macrolide | inhibit protein synthesis; inhibits peptidyl transferase activity at 50S subunit e.g. erthromycin, roxithromycin |
