The Centers for Disease Control and Prevention (CDC) recommends its use for post-exposure prophylaxis for anthrax inhalation.[2] It also has other off-label uses, such as erysipeloid, Lyme disease (if doxycycline contraindications exist), and infectious endocarditis prophylaxis, as well as prophylaxis in patients with prosthetic joints undergoing dental procedures. It can be effective in periodontitis in combination with metronidazole and is one of the first-line treatments for group A streptococcus pharyngitis. Amoxicillin is in the class of beta-lactam antibiotics. Beta-lactams act by binding to penicillin-binding proteins that inhibit a process called transpeptidation, leading to activation of autolytic enzymes in the bacterial cell wall. This process leads to lysis of the cell wall, and thus, the destruction of the bacterial cell.

This type of activity is referred to as bactericidal killing. Amoxicillin administration can also be in combination with a beta-lactamase inhibitor. Some examples of these are clavulanic acid and sulbactam. These beta-lactamase inhibitors work by binding irreversibly to the catalytic site of an organism’s penicillinase enzyme, which causes resistance to the original beta-lactam ring.

These drugs do not have inherent bactericidal activity; however, when coupled with amoxicillin, they may broaden spectrum amoxicillin to organisms that produce the penicillinase enzyme.[3] Administration.

Bactericidal antibiotics, such as amoxicillin, often are most effective in a “time-dependent” manner, rather than a “concentration-dependent” manner. Time-dependent refers to the time that serum concentrations exceed the minimum-inhibitor-concentration for the

microorganism

Therefore, they are often dosed more frequently, rather than the concentration-dependent drugs, which can be dosed, for example, daily. The more “around-the-clock” dosing provides less variation in peak and trough serum levels.

Amoxicillin is an oral antibiotic; whereas, ampicillin can be given orally, intravenously, or intramuscularly. Amoxicillin comes in immediate-release or extended-release tablets. If given in suspension, it may be mixed and

administered

Extended-release tablets should not be crushed, and the administration should be within 1 hour after finishing a meal. Amoxicillin is sometimes preferred over penicillin in children because of its taste. It is important to note that it is excreted by in the majority of people by the kidney, and some renal adjustment and extra caution may be necessary for renal insufficiency. It is reported to be partially dialyzable, and therefore, immediate-release tablets can be an option for dosing after hemodialysis. There are no

guidelines

Crystalluria, nephritis, and hemolytic anemia can happen with prolonged administration.

Of note, patients who take amoxicillin may have less diarrhea than those who take ampicillin, which may lead to better absorption in the gut. Another significant complication to be aware of is hypersensitivity reactions.

Amoxicillin can lead to type-I, II, III, or IV reactions. It is important to differentiate between a type-I and type-IV hypersensitivity reaction because one may be more dangerous than the other.

A type-I reaction is an IgE-mediated hypersensitivity to a sensitized patient that triggers widespread histamine release leading to an urticarial like pruritic rash or even more severe systemic symptoms, such as anaphylaxis. A type-IV hypersensitivity reaction does not get mediated by histamine release, and is more papular or morbilliform

and

type

These types of reactions are not known to lead to anaphylaxis.

Any previous anaphylactic reaction or serious skin reaction (for example, Stevens-Johnson syndrome) to amoxicillin or any other beta-lactam is a significant contraindication to amoxicillin. These reactions may have crossover sensitivity with cephalosporins or carbapenems. It is important to note that newer data has suggested a much lower cross-reactivity with cephalosporins and carbapenems than once suspected.

Another important consideration is to determine if the patient’s allergic rash is a type-I or a type-IV hypersensitivity reaction.

Occasionally patients will report a childhood allergy to amoxicillin, which is, in fact, a type-IV-mediated hypersensitivity reaction, often in the setting of infectious mononucleosis; this is not a contraindication to giving repeat amoxicillin. A type-1 mediated hypersensitivity reaction is, however, a contraindication given that a repeat exposure puts the patient at risk for anaphylaxis.

Skin testing has been approved to help assist in hypersensitivity to penicillins.

Reports are that the risk of an allergic reaction in a patient with a positive skin test is roughly four percent, whereas a negative skin test has a relatively high sensitivity in ruling out a type-I hypersensitivity reaction.[4] Monitoring. It is essential to be aware of hypersensitivity reactions, and the patient should understand to notify their physician of any rashes.[4] Mild diarrhea is often toleratable.[5] However, prolonged diarrhea with fever and abdominal pain should prompt evaluation by a clinician.

In a patient on a short-term course of amoxicillin, no specific laboratory monitoring parameters are suggested.

During prolonged administration, such as for osteomyelitis, it is essential to monitor renal and hepatic function as well as hematologic function periodically throughout treatment. Amoxicillin is a common antibiotic that is often prescribed by nurse practitioners, primary care providers, and internists. The drug is very safe, but it is essential always to get a proper history of allergy before prescribing the medication.[4][6] Despite its safety record and frequency of use, amoxicillin still requires the efforts of an interprofessional healthcare team.

The clinician (MD, DO, NP, PA) will initiate therapy, but a pharmacist should verify the dosing and duration are correct for the infection being treated and verify that there are no drug interactions that could impede treatment.

Nursing can counsel on administration, verify compliance, reinforce along with the pharmacist to take the entire course, and not stop when they start to feel better.

Any issues the nurse or pharmacist encounters need to go to the prescriber immediately.

These examples of interprofessional team stewardship will improve the likelihood of positive
