Azithromycin is an antibiotic medicine, containing an active ingredient of the same name. Following its development, it was marketed by Pfizer under the brand name Zithromax in the early 1990s. The medicine is employed by doctors to treat a range of bacterial infections, including chlamydia.
- Easy to use tablet medication
- Single dose treatment for chlamydia
The most common sexually transmitted infection in the UK, there are over 100,000 cases of chlamydia reported to the NHS every year. The illness is caused by a bacteria called chlamydia trachomatis, and is passed from one person to another through unprotected intercrouse.
Symptoms of chlamydia include pain, irregular vaginal or penile discharge, or increased menstrual bleeding in women; however it is thought that around three quarters of female cases and half of all male cases will be asymptomatic, producing no visible effects. This makes it doubly important to get tested if you have had unprotected with multiple partners, or think you may have come into contact with the disease.
As a macrolide antibiotic, Azithromycin works by combatting the bacterial cells responsible for spreading infection. These bacteria increase their number through self-reproduction. To do this, they must generate a protein, which facilitates the correct conditions for them to multiply. The antibiotic works by inhibiting the production of this protein. Once the bacteria can no longer develop its presence, it becomes susceptible to the body’s natural defences, which kill the infection.
For the the treatment of STIs and urethral infections, only one dose of Azithromycin may be needed.
The main agent in Azithromycin is an antibiotic substance of the same name. It belongs to the macrolide category within this medicine, and has a versatile range of uses in treating bacterial infections. It works by stopping the bacteria causing the infection from developing and spreading, which it does by interfering with the process of protein synthesis.
These bacteria require the generation of certain proteins, to be able to copy their genetic material and multiply. Once their capacity to do this has been inhibited, their growth pattern comes to a halt, and the immune system destroys what remains of the bacteria.
