Pharmacology Flashcards
-Penicillin & Aminoglicosides are never mixed in the same syringe.
≫ Inactivation
Bactericidal & bacteristatic antibiotics shouldn’t be combined for the simultaneous treatment of the same organism
Bactericidal is effective in presence of actively growing bacteria

≫ Both can cause ototoxicity & nephrotoxicity

Which of the following antibiotics for UTI treatment would not be given orally?
a. Amoxicillin
b. Ciprofloxacin
c. Ceftriaxone
d. Trimethoprim/sulphamethoxazole
