Phenoxymethylpenicillin, also known as penicillin V (PcV) and penicillin VK, is an antibiotic useful for the treatment of a number of bacterial infections. [2] Specifically it is used for the treatment of strep throat, otitis media, and cellulitis. [2] It is also used to prevent rheumatic fever and to prevent infections following removal of the ...
However, these classifications are based on laboratory behavior. The development of antibiotics has had a profound effect on the health of people for many years. Also, both people and animals have used antibiotics to treat infections and diseases. In practice, both treat bacterial infections. [1]
The usual dose by mouth is one capsule of 250 mg 4 times a day in adults and half the adult dose as a syrup for children under the age of 10 years but over 2. [4] For children below the age of 2 years, the oral dose is a quarter of the adult oral dose. [3] Ampicillin/flucloxacillin is taken orally about half an hour before food. [5]
Streptomycin is an antibiotic medication used to treat a number of bacterial infections, [3] including tuberculosis, Mycobacterium avium complex, endocarditis, brucellosis, Burkholderia infection, plague, tularemia, and rat bite fever. [3] For active tuberculosis it is often given together with isoniazid, rifampicin, and pyrazinamide. [4]
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
Ampicillin/sulbactam is also used when the cause of an infection is not known (empiric therapy), such as intra-abdominal infections, skin infections, pneumonia, and gynecologic infections. It is active against a wide range of bacterial groups, including Staphylococcus aureus , Enterobacteriaceae , and anaerobic bacteria .
Group B streptococcal infection, also known as Group B streptococcal disease or just Group B strep infection, is the infectious disease caused by the bacterium Streptococcus agalactiae. Streptococcus agalactiae is the most common human pathogen belonging to group B of the Lancefield classification of streptococci —hence the name of group B ...
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. [1] [2] They may either kill or inhibit the growth of bacteria.
