Across
- 2. A core antitubercular prodrug that inhibits mycolic acid synthesis, frequently co-prescribed with vitamin B6 to prevent peripheral neuropathy.
- 5. A urinary tract antiseptic concentrated rapidly in the renal tubules, contraindicated in patients with a creatinine clearance below thirty.
- 7. A sulfonamide antimetabolite that competitively inhibits dihydropteroate synthase, routinely paired with trimethoprim for synergistic efficacy.
- 10. An aminoglycoside antibiotic requiring therapeutic drug monitoring due to its high potential for permanent ototoxicity and acute tubular necrosis.
- 11. An oxazolidinone antibiotic that treats resistant Gram-positive infections, carrying a risk of serotonin syndrome if combined with SSRIs.
- 12. A pharmacologically inactive compound, such as valaciclovir, that must be converted by enzymes into its active antimicrobial form.
- 15. An older polymyxin class antibiotic revived as a last-resort option to treat multi-drug resistant Gram-negative superbugs.
- 17. An extended-spectrum antipseudomonal penicillin routinely combined with tazobactam to overcome bacterial beta-lactamase defenses.
- 22. A macrolide antibiotic that binds to the 50S ribosomal subunit to inhibit protein synthesis, widely used for atypical respiratory pathogens.
- 23. A third-generation cephalosporin with excellent cerebrospinal fluid penetration, commonly selected for treating bacterial meningitis.
- 25. The historical beta-lactam antibiotic class discovered by Alexander Fleming, primarily targeting Gram-positive cell wall cross-linking.
- 26. A foundational macrolide antibiotic that acts as a strong motilin receptor agonist, frequently causing severe gastrointestinal cramping.
- 27. An oral neuraminidase inhibitor administered within forty-eight hours of symptom onset to shorten the duration of influenza infections.
- 28. A glycopeptide antibiotic that inhibits cell wall synthesis by binding to D-alanyl-D-alanine, associated with red man syndrome if infused too rapidly.
- 29. A classification of antimicrobial action where the agent directly kills the target pathogen rather than merely inhibiting its reproduction.
Down
- 1. The development of harmful target-organ adverse profiles, such as bone marrow suppression or hepatotoxicity, during chemotherapeutic regimens.
- 3. A primary antimycobacterial agent that inhibits bacterial RNA polymerase, routinely counseling patients regarding benign orange-red discoloration of bodily fluids.
- 4. A potent polyene antifungal agent that binds to ergosterol to form membrane pores, notorious for severe nephrotoxicity and infusion reactions.
- 5. A topical polyene antifungal suspension utilized as a swish-and-swallow rinse to treat oral candidiasis infections.
- 6. A class of bactericidal protein synthesis inhibitors that bind to the 30S subunit, requiring oxygen for active transport into cells.
- 8. A tetracycline antibiotic that binds reversibly to the 30S ribosomal subunit, commonly avoided in young children due to permanent tooth discoloration.
- 9. An antiprotozoal and antibacterial agent that disrupts DNA structures in anaerobic organisms, famous for triggering a disulfiram-like reaction with alcohol.
- 13. The evolutionary mechanism by which microorganisms develop strategies to survive exposures to previously effective antimicrobial agents.
- 14. An azole antifungal drug that inhibits the synthesis of ergosterol by targeting fungal cytochrome P450 enzymes.
- 16. A spontaneous genetic alteration in an organism's DNA or RNA code that can rapidly confer immediate drug insensitivity.
- 18. A lincosamide antibiotic that binds to the 50S subunit, carrying a high clinical correlation with Clostridioides difficile pseudo-membranous colitis.
- 19. A guanosine analogue antiviral drug that requires activation by viral thymidine kinase, first-line for herpes simplex virus infections.
- 20. A specialized enzyme system targeted by novel antifungal compounds to disrupt the structural integrity of fungal cell membranes.
- 21. A broad-spectrum carbapenem antibiotic highly resistant to beta-lactamases, reserved for severe multi-drug resistant nosocomial infections.
- 24. A fluoroquinolone antibiotic that inhibits bacterial DNA gyrase, carrying a prominent black-box warning for tendonitis and tendon rupture.
