Antibiotics are a group of medicines that are used to treat infections caused by bacteria and certain parasites.They are normally prescibed for more serious bacteria infections.
When prescibed,it is important to take the entire course of antibiotics which helps to prevent resistance developing to that antibiotic.Antibiotic can be taken by mouth as liquids,tablets,or capsules,or they can be given by injection.It is also available as creams,ointments or lotions to apply to the skin to treat certain infections.
There are various antibiotics available and they come in various different brand names.Antibiotics are usually grouped together based on how they work.Each type of antibiotic only works against certain types of of bacteria or parasites.This is why different antibiotics are used to treat different types of infection.
The main types of antibiotics include:
Penicillins-For example penicillin V,flucloxacillin and amoxicillin.
Cephalosporins-For example cefaclor,cefadroxil,cefalexin
Tetracyclines-For example tetracycline,doxycyline and minocycline
Aminoglycosides-For gentamicin,amikacin and tobramycin
Macrolides-For example erythromycin,azithromycin and clarithromycin
Clindamycin,Sulfonamides and trimethoprim-
Metronidazole and tinidazole-For example ciprofloxacin,levofloxacin and norfloxacin
How does Antibiotics work:- Antibiotics work by killing bacteria or the parasite.This is often done by interfering with the structure of the cell wall of the bactreium or parasite.Some work by stopping bacteria or parasite from multiplying.
How antibiotic is prescibed:-The choice of antibiotic mainly depends on which infection you have and the bacterium or parasite your doctor thinks is causing your infection.This is because each antibiotic is effective only against certain bacteria or parasite.Other factors for choice of antibiotic include how severe the infection is ,how well your kidneys and liver is working,dosing schedule,othe r medications you may be taking,common side –effects,a history of having an allergy to a certain type of antibiotics or if you are breast feeding or pregnant.
When taking antibiotics:-It is important to take antibiotics in the correct way.If you do not take it in the right way it may reduce how well they work and affect their absorption and therefore may not work as well.When the entire course prescibed by the doctor is not taken and stopped mid-course,the bacteria may be partially treated and not completely killed,bacteria may then become resistant to that antibiotic.Overuse of antibiotics has led to some bacteria mutating and become resistant to some antibiotics,which may then not work when really needed,for e.gMRSA which has become resistant to may different antibiotics and difficult to treat with orthodox antibiotics!
