Is Cefuroxime a penicillin or antibiotic?

Pharmacodynamics. Cefuroxime is a β-lactam type antibiotic. More specifically, it is a second-generation cephalosporin. Cephalosporins work the same way as penicillins: they interfere with the peptidoglycan synthesis of the bacterial wall by inhibiting the final transpeptidation needed for the cross-links. This effect is bactericidal.

How are bicyclic -lactams numbered?from en.wikipedia.org

By convention, the bicyclic β-lactams are numbered starting with the position occupied by sulfur in the penams and cephems, regardless of which atom it is in a given class. That is, position 1 is always adjacent to the β-carbon of β-lactam ring. The numbering continues clockwise from position one until the β-carbon of β-lactam is reached, at which point numbering continues counterclockwise around the lactam ring to number the remaining to carbons. For example, the nitrogen atom of all bicyclic β-lactams fused to five-membered rings is labelled position 4, as it is in penams, while in cephems, the nitrogen is position 5.

What are the roles of healthcare professionals in the use of azithromycin?from ncbi.nlm.nih.gov

Healthcare professionals in many different roles can contribute to the appropriate use of azithromycin, and all antimicrobial agents. Physicians and non-physician prescribers should use azithromycin judiciously and make use of available evidence and society guidelines. Physicians working with and/or supervising non-physician prescribers should ensure that all prescriptions accord with evidence- and guideline-based practice.[40] [ Level 3] Additionally, patients requesting antimicrobial therapy when it is not necessary, or sharing concerns about drug allergies, should be provided with education and appropriate follow-up. Nurses can play an important role in addressing patient questions and facilitating continuity of care. Pharmacists are an invaluable resource for helping providers select the most appropriate antimicrobial agent, dosing, and duration of treatment. They can also help providers and patients avoid interactions between azithromycin and other drugs that affect the QTc interval.

How long does penicillin last?

Most of the available penicillins have a short half-life, less than an hour mostly. Administration of the parenteral agents is every four hours, usually when treating serious systemic infections with normal renal function.  Piperacillin and ampicillin require dose adjustment when given in patients with renal insufficiency (GFR less than 10 ml/min).  Other agents like nafcillin, oxacillin, cloxacillin, and dicloxacillin have the hepato-biliary mode of excretion and therefore require no modification in renal impairment.
