The most likely explanation is that the original patent of ofloxacin is about to expire. In order to keep the patent and continue to earn profits, pharmaceutical companies have to separate the two optical rotators and sell levofloxacin separately, which is the highest interest.
The main side effects of levofloxacin hydrochloride are as follows:
(1) If it is taken with non-steroidal anti-inflammatory and analgesic drugs, such as aspirin and ibuprofen, it may cause muscle convulsions.
(2) If it is used together with oral hypoglycemic drugs, it may cause blood sugar disorders, including hyperglycemia and hypoglycemia. Some people will have gastrointestinal reactions, such as nausea, vomiting, diarrhea and indigestion, and some people will also have allergic situations, such as edema, urticaria, rash, itching, erythema and maculopapular rash.
(3) Some people may also have nervous system reactions, such as muscle tremor, numbness, abnormal vision and drowsiness, and some people also have headaches and dizziness.
(4) Long-term use of this drug may also lead to the increase of urea nitrogen in urine or transient liver damage, and sometimes anemia, leukopenia and thrombocytopenia may also occur. Patients under the age of 18 are forbidden to take such drugs because it will affect the development of patients' nervous system.
