What are the different classes of antibiotics?

1. Penicillins. Another name for this class is the beta-lactam antibiotics, referring to their structural formula. The penicillin class contains five groups of antibiotics: aminopenicillins, antipseudomonal penicillins, beta-lactamase inhibitors, natural penicillins, and the penicillinase resistant penicillins.

What is the most highly utilized class of medicine?

From treatments for painful strep throat or ear infections as a child, to burning urinary tract infections or itchy skin infections as an adult, antibiotics are one of the most highly utilized and important medication classes we have in medicine.

What is beta lactam used for?

These injectable beta-lactam antibiotics have a wide spectrum of bacteria-killing power and may be used for moderate to life-threatening bacterial infections like stomach infections, pneumonias, kidney infections, multidrug-resistant hospital-acquired infections and many other types of serious bacterial illnesses.

How do aminoglycosides inhibit bacterial synthesis?

Aminoglycosides inhibit bacterial synthesis by binding to the 30S ribosome and act rapidly as bactericidal antibiotics (killing the bacteria). These drugs are usually given intravenously (in a vein through a needle). Common examples in this class are: Generic.

What is glycopeptide used for?

Members of this group may be used for treating methicillin-resistant staphylococcus aureus (MRSA) infections, complicated skin infections, C. difficile-associated diarrhea, and enterococcal infections such as en docarditis which are resistant to beta-lactams and other antibiotics.

They should only be considered when treatment with other, less toxic antibiotics, has failed. Ask your doctor about the warnings associated with this class of drug before you take it.

However, patients with bloodstream infections have typically been excluded from these studies, and so data to inform the duration of antibiotic therapy for this patient population are lacking.

Why is it important to prescribe a shorter antibiotic treatment course?

However, it also is important to provide a substantial treatment course so that an infection is treated adequately and relapse is prevented. This article is a review of the general principles for setting optimal antibiotic durations of therapy.

What antibiotics are used for urinary tract infections?

Fosfomycin tromethamine, quinolones, nitrofurantoin, trimethoprim-sulfamethoxazole and beta-lactams are some of the antibiotics used to treat urinary tract infections. Even though these antibiotics can concentrate well in the genitourinary tract, each can differ in duration of treatment.

What is the procalcitonin test?

The use of biomarkers, such as C-reactive protein (CRP), and the procalcitonin test also has been instrumental in evaluating antibiotic response and determining the duration of antibiotic therapy. Unlike CRP, procalcitonin is more specific to bacterial infections; therefore, the test has been used to curtail unnecessary antibiotic usage. Use of the procalcitonin-guided algorithm has been shown to reduce the duration of exposure to antibiotics by ≤25% in patients with lower respiratory tract infections 16 and 23% in patients who are critically ill. 17
