1. How to choose antibiotic route?
Antibiotics are substances of microbial origin, prepared by synthetic or semi-synthetic chemical methods. Antibiotics are used to inhibit the growth or kill pathogenic bacteria. The two main dosage forms of antibiotics are oral and injectable. Depending on the specific condition of the patient, the doctor will consider deciding to use the appropriate antibiotic route. Oral antibiotics are usually preferred. However, in cases of severe infection or the patient cannot drink, the doctor will prescribe injectable antibiotics. During treatment, the doctor will flexibly switch parenteral antibiotics to oral and vice versa depending on the course of the disease.
