The patient has NKDA and a history of COPD, atrial fibrillation, and shingles. She is given IV fluids to treat the dehydration, 1 gram of Rocephin® IVPB and discharged with a prescription for penicillin drug therapy to treat the UTI. Medication history is as follows: 1. amoxicillin 250mg PO qid x 7 days 2. warfarin 2mg PO q am 3. digoxin 0.25mg PO q am 4. prednisone 10mg q am

Answer 1

Ans) a. cell wall synthesis inhibitor

Explaination:

- Mechanism of Action
Amoxicillin is similar to penicillin in its bactericidal action against susceptible bacteria during the stage of active multiplication. It acts through the inhibition of cell wall biosynthesis that leads to the death of the bacteria.

b. Bactericidal - inhibits growth and prevents replication

As a beta-lactam antibiotic, amoxicillin is mainly bactericidal. Inhibits third and final stage of bacterial cell wall synthesis by preferentially binding to specific PBPs located inside the bacterial cell wall.
