What is tetracycline and how does it work?

Tetracycline is used to treat a wide variety of infections, including acne. It is an antibiotic that works by stopping the growth of bacteria. This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu).

What is the work of tetracycline in the body?

Tetracycline is an antibiotic that fights infection caused by bacteria. Tetracycline is used to treat many different bacterial infections of the skin, intestines, respiratory tract, urinary tract, genitals, lymph nodes, and other body systems.

What are the limitations of antibiotics?

Cons of taking antibiotics

• If you take antibiotics often, your body can build a resistance to antibiotic drugs, which could cause antibiotics to become less effective.
• The longer the course of treatment for an antibiotic, the more damage that can be done to the body’s immune system.

What is the exact action of tetracycline?

Tetracycline is a short-acting antibiotic that inhibits bacterial growth by inhibiting translation. It binds to the 30S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome. It also binds to some extent to the 50S ribosomal subunit. This binding is reversible in nature.

How does tetracycline affect and destroy bacteria?

Tetracyclines probably penetrate bacterial cells by passive diffusion and inhibit bacterial growth by interfering with protein synthesis or by destroying the membrane. A growing number of various bacterial species acquire resistance to the bacteriostatic activity of tetracycline.

Why does tetracycline not affect human cells?

They inhibit protein synthesis in both bacterial and human cells. Bacteria have a system that allows tetracyclines to be transported into the cell, whereas human cells do not; human cells therefore are spared the effects of tetracycline on protein synthesis.

What are some of the side effects of tetracycline and when is it contraindicated?

Who should not take TETRACYCLINE HCL?

• diarrhea from an infection with Clostridium difficile bacteria.
• pseudotumor cerebri, a condition with high fluid pressure in the brain.
• liver problems.
• decreased kidney function.
• pregnancy.

What are the advantages of restricting antibiotics?

If bacterial spread between patients is significant, the advantages of deliberately using the restricted antibiotics can outweigh the disadvantages, and lead to fewer instances of bacteria resistant to all available drugs in the long term as well as more effective treatment in the short term.

How do antibiotics become ineffective?

Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.

Who should not use tetracycline?

Do not give tetracyclines to infants or children 8 years of age and younger unless directed by your doctor. Tetracyclines may cause permanently discolored teeth and other problems in patients in these age groups.
