What is an antibiotic simple definition?
Antibiotics are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply.
What is the role of antibiotics?
Antibiotics are used to treat or prevent some types of bacterial infection. They work by killing bacteria or preventing them from reproducing and spreading. Antibiotics aren’t effective against viral infections, such as the common cold, flu, most coughs and sore throats.
What is antibiotic and its classification?
Antibiotics can be divided into two classes based on their mechanism of action. Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics inhibit their growth or reproduction. One way that bactericidal antibodies kill bacteria is by inhibiting cell wall synthesis.
What are the 7 types of antibiotics?
7 Types of Antibiotics
- Penicillins such as penicillin and amoxicillin.
- Cephalosporins such as cephalexin (Keflex)
- Macrolides such as erythromycin (E-Mycin), clarithromycin (Biaxin), and azithromycin (Zithromax)
- Fluoroquinolones such as ciprofolxacin (Cipro), levofloxacin (Levaquin), and ofloxacin (Floxin)
What are antibiotics in one word?
An antibiotic is a substance used to kill bacteria. If you’re coughing up green stuff, the doctor might give you an antibiotic to fight the infection. Since the prefix anti- means fighting, opposing, or killing, and bios is the Greek word for “life,” antibiotic literally means life-killing.
Do antibiotics weaken immune system?
Will antibiotics weaken my immune system? Very rarely, antibiotic treatment will cause a drop in the blood count, including the numbers of white cells that fight infection. This corrects itself when the treatment is stopped.
What is the best antibiotic?
Which Antibiotic Will Work Best?
- Ceftriaxone (Rocephin)
- Cephalexin (Keflex)
- Ciprofloxacin (Cipro)
- Fosfomycin (Monurol)
- Levofloxacin (Levaquin)
- Nitrofurantoin (Macrodantin, Macrobid)
- Trimethoprim/sulfamethoxazole (Bactrim, Septra)
What happens when you take antibiotics?
When you take an antibiotic, the sensitive bacteria are eliminated. The bacteria that survive during antibiotic treatment are often resistant to that antibiotic. These bacteria often have unique characteristics that prevent antibiotics from working on them.
What are the 2 types of antibiotics?
The main types of antibiotics include:
- Penicillins – for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin.
- Cephalosporins – for example, cefaclor, cefadroxil and cefalexin.
- Tetracyclines – for example, tetracycline, doxycycline and lymecycline.
- Aminoglycosides – for example, gentamicin and tobramycin.
What is a common antibiotic?
Top 10 List of Generic Antibiotics
- sulfamethoxazole and trimethoprim.
What are the 5 mechanisms of action of antibiotics?
- Five Basic Mechanisms of Antibiotic Action against Bacterial Cells:
- Inhibition of Cell Wall Synthesis.
- Inhibition of Protein Synthesis (Translation)
- Alteration of Cell Membranes.
- Inhibition of Nucleic Acid Synthesis.
- Antimetabolite Activity.
What is the most expensive antibiotic?
The cephalosporins are among the most expensive antibiotics in use today; thus, use of these expensive agents must be justified by lower toxicity, greater efficacy, or both in comparison with drugs of more reasonable cost.
What is the best antibiotic for a bacterial infection?
Bacterial infections are treated with antibiotics such as amoxicillin, erythromycin and ciprofloxacin. There are many different types of antibiotic, with different ways of working; the choice depends on the type of infection you have. Fungi commonly cause skin infections such as athlete’s foot and ringworm.
How do I choose antibiotics?
How to Choose an Antibiotic
- Make sure you know normal flora and the causes of common infections.
- Know your specialities serious and common infections, the micro-organisms that cause these and the usual treatments for them.
