Beta-lactamase inhibitors are co-administered with beta-lactam antimicrobials to prevent antimicrobial resistance. They do this by inhibiting serine beta-lactamases, enzymes that inactivate the beta-lactam ring which are a common chemical structure to all beta-lactam antimicrobials. This activity outlines the different types of beta-lactamase inhibitors. It discusses the pharmacological properties of beta-lactamase inhibitors, their medical uses, administration methods, side effects, and other properties. It also highlights providers' critical role in correctly administering beta-lactamase inhibitors in combination with beta-lactam antimicrobials and counseling patients regarding medication adherence. Objectives: Identify the different forms of beta-lactamase inhibitors, their pharmacological properties, and their medical indications. Assess the potential adverse effects of beta-lactamase inhibitors. Determine the methods of monitoring and administration of beta-lactamase inhibitor therapy. Communicate the importance of medication adherence, routine monitoring of patients taking beta-lactamase inhibitor therapy, and the importance of collaboration amongst the interprofessional team to enhance care delivery.

Many causes of organ toxicity due to beta-lactamase inhibitor therapy are directly related to the toxic effects of the beta-lactam antimicrobial with which they are coadministered. Allergic reactions can lead to bronchoconstriction, urticaria, intravascular hemolysis, and immune-mediated hemolytic anemia. Neurotoxicity, nephrotoxicity, genotoxicity, and urogenital organ toxicity have also been noted.[31] Though beta-lactamase inhibitor therapy is generally considered safe, the wide array of toxic effects associated with these drugs underscores the importance of routinely monitoring patients taking beta-lactam antimicrobial/beta-lactamase inhibitor combinations. The treatment for toxicity associated with beta-lactamase inhibitor therapy is the cessation of drug use.

Beta-lactamase inhibitors are medications used ubiquitously in modern medicine due to their ability to combat bacterial antimicrobial resistance mechanisms. Antimicrobial resistance poses an enormous global public health challenge.[32] Therefore, careful monitoring and prescribing of patients taking Beta-lactamase inhibitors combined with beta-lactam antimicrobials are paramount. Interprofessional health teams of doctors, nurses, pharmacists, and other healthcare professionals must work together to determine the necessity of treatment and counsel patients regarding the proper administration of this class of medications. Patients must complete their entire course of medication and must not share this medication with others. By working together, members of an interprofessional healthcare team can strive to prevent adverse outcomes for the patient and antimicrobial resistance in the community.
