What group on the 5th generation cephalosporin is going to be cleaved and makes the molecule a prodrug?
What type of adverse effect/side effect is described by: - cytotoxic antibiotics, hemolytic anemia, leukopenia, thrombocytopenia, drug - induced nephritis
What is the only fourth generation cephalosporin that is on the market for clinical use?
Penicillins that are poor acidic stability are best to be given in what route?
Which enzyme cleaves the beta - lactam ring and have catalytic activity to developing bacterial resistance?
What type of adverse effect/side effect it described by: - immediate urticaria, hypotension, laryngeal edema, bronchospasm with or without CV collapse
Definition: - this section of certain drugs (cefiderocol) binds to iron atoms that are necessary for the normal biochemistry of an organism in order to follow the iron into the cell and when this is attached to a drug molecule then the drug also gets into the organism to do its work
Reduced uptake of the drug is a significant mutation in ___________ bacteria
Which enzyme is a hydrolytic enzyme that cleaves in a way that still keeps the beta - lactam ring in tact that has catalytic activity to bacterial resistance to beta - lactams?
What kind of substitution group is the best for parenteral formulations in penicillins?
What functional group does aztreonam have in place of carboxylic acid that makes it extremely polar and therefore has gram negative activity?
Insoluble salts of a penicillin are used in what formulations?
What specific type of beta - lactamase uses the hydroxyl group of a serine to open up the beta - lactam ring?
Elimination by biliary route is important for what drug?
What specific type of beta - lactamase uses metals to open up the beta - lactam ring?
