erythromycin - in the form of intramuscular or intravenous injections. With this method, the drug enters the site of infection faster and acts more actively. The disadvantage of this route of administration is painfulness during the erythromycin. Injections are used for moderate and severe diseases.
Local - applying ointments or creams directly to the site of infection. This method of drug delivery is mainly used for skin infections - erysipelas, as well as in ophthalmology - with an infectious lesion of the eyefor, for example, tetracycline ointment for conjunctivitis.
Important: erythromycin only a nurse in a polyclinic or hospital should give injections! Injecting antibiotics at home is strongly discouraged. The route of administration is determined only by the doctor.
In this case, many factors are taken into account: the absorption of the drug in the gastrointestinal tract, the state of the digestive system as a whole (in some diseases, the absorption rate decreases, and the effectiveness of treatment decreases). Some drugs can only be administered one way.
