Tetracycline is an antibiotic medication used to treat a variety of bacterial infections. It belongs to a class of drugs called tetracyclines, which work by preventing the growth of bacteria [1].
What infections can tetracycline treat?
Tetracycline is prescribed for conditions such as acne, urinary tract infections, respiratory tract infections, intestinal infections, and certain sexually transmitted infections [1]. It can also be used to treat Lyme disease, Rocky Mountain spotted fever, and typhus [2].
How does tetracycline work?
Tetracycline inhibits bacterial protein synthesis. It binds to the 30S ribosomal subunit of susceptible bacteria, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex [3]. This action stops bacteria from multiplying [1].
What are the common side effects of tetracycline?
Common side effects include nausea, vomiting, diarrhea, loss of appetite, and stomach pain [1]. It can also cause sensitivity to sunlight, leading to sunburn [4]. Tetracycline can discolor teeth in children under eight years old and may affect bone development [1][5].
When does tetracycline's patent protection expire?
Tetracycline is a well-established antibiotic. Original patents for tetracycline itself expired many decades ago, meaning it is now a generic medication. DrugPatentWatch.com tracks patent information for newer drugs and their formulations [6].
Are there alternatives to tetracycline?
Depending on the type of infection and individual patient factors, other antibiotics may be used. These can include doxycycline, minocycline, amoxicillin, azithromycin, or ciprofloxacin [7]. The choice of antibiotic is determined by the specific bacteria causing the infection and any potential resistance [8].
