Antibiotics Classification

An antibiotic was originally a material created by one microorganism that selectively inhibits another’s development. Since then, synthetic antibiotics have been developed that perform comparable tasks, typically chemically similar to natural antibiotics. There are no effects of antibiotics on viral infections.

Antibiotics are antibiotics that help stop bacteria-caused infections. By destroying the bacteria or preventing them from cloning themselves or reproducing, they do this. The word antibiotic means “against life.” Literally, any medicine that destroys germs in your body is an antibiotic.

What are Antibiotics?

A chemical material produced by a living organism, normally a microorganism, which is harmful to other microorganisms. Antibiotics are typically developed by soil microorganisms and are likely to be a means by which organisms regulate the growth of competing microorganisms in complex environments, such as soil.

In 1926, Alexander Fleming discovered penicillin, a compound that seemed to be able to suppress bacterial growth produced by fungi. Edward Chain and Howard Florey further studied penicillin in 1939 and subsequently performed penicillin studies on humans (with what were considered fatal bacterial infections). For their work that ushered in the antibiotic age, Fleming, Florey and Chain shared the Nobel Prize in 1945.

Antibiotics Classification with Examples

Antibiotics that contain an original chemical molecule from a microorganism but are further altered are called semi synthetic – for example, Penicillin V. Thos made completely in a laboratory are called synthetics such as cephalosporins.

Antibiotics are further classified according to susceptible bacteria against which they are effective or their antibacterial spectrum. Some drugs called broad spectrum antibiotics, have a wide range of effectiveness against both gram positive and gram negative bacteria. With broad spectrum antibiotics it is possible to eliminate pathogen without initially performing laboratory tests to identify the exact pathogen involved, so treatment to identify the exact pathogen involved. Other antibiotics are called narrow spectrum antibiotics.

List of Classification of Antibiotics

While there are many antibiotic classification schemes based on the bacterial continuum (broad versus narrow) or route of administration (injectable versus oral versus topical) or action type (bactericidal versus bacteriostatic), the chemical structure is the most useful. Antibiotics will normally exhibit identical trends of potency, toxicity, and allergic potential within a systemic class.

1. Penicillin:

Penicillin V is an antibiotic in the penicillin group of drugs which helps to fight bacteria in the body system. Penicillin is used to treat many types of infections caused by bacteria which an example is ear infection. During the stage of active replication, penicillin G is bactericidal against microorganisms prone to penicillin. It works by inhibiting cell-wall mucopeptide biosynthesis. It is not active against penicillinase-producing bacteria containing several staphylococcal strains.

2. Cephalosporins:

In wealthy countries, cephalosporin antibiotics have been a big part of the antibiotic formulation for hospitals. Every day, they are recommended for a large range of infections. Their undoubted success is focused on lower risks of allergens and toxicity, as well as a wide variety of sports. However, it is the above attribute that allows microorganisms that are immune to these agents to be chosen.

3. Fluoroquinolone:

Fluoroquinolones are certified antibiotics for serious , life-threatening bacterial infections. As on all antibiotic products, official guidelines on the proper use of antibacterial agents should be taken into account.

4. Tetracycline:

Tetracycline has commonly been used to treat acne and lots of infection in the skin and also respiratory tract infections, it is also known to be effective in the treatment of urinary infections. Since the 1950s, tetracyclines have been used in the treatment of a large spectrum of gram-positive and gramme-negative bacterial infections. In addition to being effective against typical bacteria, tetracyclines and a number of non-infectious diseases have been used to treat infections due to intracellular chlamydiae, mycoplasmas, rickettsiae and protozoan parasites.

5. Macrolides:

Macrolides are often indicated for treating community acquired bacterial pneumonia because of their action against numerous causative organisms. Microbial resistance is becoming increasingly common, however. Macrolides have also been used for the treatment of sexually transmitted infections caused by Chlamydia trachomatis. Macrolides are also used for skin and soft tissue infections caused by staphylococci, Propionobacter acnes.

Frequently Asked Questions on Antibiotics Classification

How do antibiotics work?

By either killing bacteria or halting and suspending their development, antibiotics combat bacterial infections. They do this by attacking the wall or covering the bacteria inside it. Disrupting the replication of bacteria.

What’s a natural antibiotic?

Honey, traced back to ancient times, is one of the oldest antibiotics known. Honey is also used by Egyptians as a natural antibiotic and skin protectant. There is hydrogen peroxide in honey, which may account for some of its antibacterial effects.

What can be treated with penicillin?

In patients with an infection caused by bacteria, penicillin is given. According to the National Library of Medicine, certain forms of bacterial infections that can be treated with penicillin include pneumonia, strep throat, meningitis, syphilis and gonorrhoea. To avoid dental infections, it can also be used.

Is amoxicillin a cephalosporin?

Although each beta-lactam antibiotic incorporates cephalexin and amoxicillin, they are not the same. Cephalexin is an antidote for cephalosporin, and amoxicillin is a derivative of penicillin. Although some of the same bacterial species are covered by them, they each cover various species.

What are the side effects of fluoroquinolones?

In general, fluoroquinolones are very effective antibiotics that do not cause severe or life-threatening adverse events. Gastrointestinal reactions (nausea, dyspepsia, vomiting) and CNS reactions such as dizziness, insomnia and headaches are the most common side effects.
