What is the use of polymyxin B eye drops?
Polymyxin B is useful in the treatment of some bacterial infections. In a specific case of eye problems, polymyxin b eye drops are suitable for use when a physician suspects an infection caused by a group of bacteria classified as a Gram negative. Symptoms that may indicate this type of infection include inflamed eyelids and the presence of pink eye or conjunctivitis.
bacterial species are widely divided into two categories for science and medicine. They are based on the appearance of bacteria after being colored with a specific technique called gram stains. A gram of negative bacteria seem reddish pink, while a gram of positive bacteria look bluish purple. The reason is a significant difference in the structure of cell walls between the two groups, which is also related to the bacteria react to antibiotics.
type of bacteria that polymyxin b eye drops and other products containing an antibiotic can kill them part of the gram negativa groups. Therefore, this antibiotic is only used when the doctor suspects that the patient has an infection caused by one of these bacterial species. One type of this type, which is an important cause of eye infections and which is sensitive to polymyxin b eye drops, is pseudomonas aeruginosa .
The sign that the bacterial species of the eye infects and causing the disease may be similar to symptoms caused by other infectious substances such as viruses. The doctor can take samples from the infected eye to send to the laboratory to check the presence of different bacterial species. In general, doctors do not want to use polymyxin b eye drops for all patients, as excessive use may lead to the development of antibiotics resistance in species. If the infection is caused by unusual bacteria, such as gram positive species or other microbes such as fungi or viruses, then the antibiotic does not have a beneficial effect.
, however, the samples analysis tend to take time, so the doctor can simply prescribe an antibiotic if any of these characteristic symptoms of infection are present. The inflammation of the eyelid and the conjunctiva, which are tissues bordering the eye itself, indicates an infection. The pink eye is another name for conjunctivitis and swelling and irritation of the inflamed area can lead to pain, tearing and even pus production. Polymixin B eye drops are designed for external use, so they are most effective in trying to treat external infections such as these.
