The strongest antibiotics available include carbapenems, vancomycin, fidaxomicin, tetracyclines (eravacycline, omadacycline, tigecycline), and macrolides (erythromycin). These antibiotics are chosen based on their broad-spectrum activity and effectiveness against a wide range of bacterial infections.
The carbapenems, imipenem and meropenem, are considered the most potent of any antibiotic class, and are for use in serious infections or when resistance compromises all other agents.
We suggest the following regimens: doxycycline + clindamycin; doxycycline + cefazolin; linezolid. We use doxycycline (usually active against MRSA) in combination because it is poorly active against Streptococcus pyogenes.
The guidelines recommend tetracycline and amoxicillin as “preferred” antibiotics. In cases of hypersensitivity, macrolides are recommended as an “alternative” antibiotic.
Examples of prescription cough medicines include benzonatate (Tessalon) and codeine-containing cough syrups, such as promethazine / codeine.
Amoxicillin (50 mg/kg/day) alone or with clavulanate is the first line antibiotic. Ceftriaxone (50 mg/kg/day) should be given to children who cannot take oral medications. Duration of the treatment varies from 10 to 28 days.
There is not one type of antibiotic that cures every infection. Antibiotics specifically treat infections caused by bacteria, such as Staph., Strep., or E. coli., and either kill the bacteria (bactericidal) or keep it from reproducing and growing (bacteriostatic).
The 'Big Three' - Most people diagnosed with NTM and who start treatment, take three antibiotics. These are usually azithromycin or clarithromycin, together with rifampicin or rifabutin, and ethambutol.
Sir Alexander Fleming FRS FRSE FRCS (6 August 1881 – 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin.
Antibiotics for pneumonia include Zithromax (azithromycin), clarithromycin, and Erythrocin (erythromycin). Azithromycin is often the first-line treatment since it is effective against many different microbes that can cause pneumonia. Antibiotics treat pneumonia caused by bacteria and some types caused by fungi.
Symptoms of cellulitis
Cellulitis makes your skin painful, hot and swollen. The area usually looks red, but this may be less obvious on brown or black skin. Your skin may also be blistered. You may also feel unwell and have flu-like symptoms, with swollen, painful glands.
Neomycin, polymyxin, bacitracin, and hydrocortisone combination is used to treat skin infections caused by certain bacteria and to treat the redness, swelling, itching, and discomfort of various skin conditions. Neomycin, polymyxin, and bacitracin are in a class of medications called antibiotics.
They discovered an intermediate compound — called premethylenomycin C lactone — whose antimicrobial activity was 100 times stronger than that of the final product. Tiny doses killed strains of bacteria known to cause hard-to-treat infections.
MRSA is one of the most common antibiotic-resistant bacteria. Symptoms of MRSA infection often begin as small red bumps on the skin that can progress to deep, painful abscesses or boils, which are pus-filled masses under the skin.
The key target molecules were members of the 'Big Four' classes of antibiotics (macrolides, aminoglycosides, β-lactams and tetracyclines), naphthoquinone antibiotics and their related antibiotics.

The 5 most over-prescribed antibiotics
Use Azithromycin 3 Day Dose Pack 3 Day Dose Pack for the full prescribed length of time, even if your symptoms quickly improve. Skipping doses can increase your risk of infection that is resistant to medication. Azithromycin 3 Day Dose Pack will not treat a viral infection such as the flu or a common cold.
Researchers from the University of Warwick and Monash University have uncovered a powerful new antibiotic compound, pre-methylenomycin C lactone, hidden inside a known bacterial pathway. In lab tests, it proved over 100 times more potent than existing antibiotics against drug-resistant bacteria like MRSA and E.
Serious bacterial infections can be effectively treated with antibiotics. These medicines either kill the bacteria or stop them multiplying. This helps your body's immune system fight the bacteria.
The following are some basic guidelines:
Treatment for a respiratory tract infection (RTI) will depend on the cause of your infection. If your RTI is caused by a virus (like the common cold), it will usually clear up by itself after a few weeks. Antibiotics will not help. If your RTI is caused by bacteria (like pneumonia), a GP may prescribe antibiotics.
Macrolides provide the best coverage for the most likely organisms in community-acquired bacterial pneumonia (CAP). Macrolides have effective coverage for gram-positive, Legionella, and Mycoplasma organisms. Azithromycin administered intravenously is an alternative to intravenous erythromycin.
Viral infections often develop gradually, such as a cold that starts with a scratchy throat and progresses to a cough and congestion. Bacterial infections, however, tend to appear suddenly and with more intensity. For example, strep throat can cause a severe sore throat and high fever that comes on quickly.
