Disease analysis: the difference between first-line drugs and second-line drugs for tuberculosis mainly lies in the efficacy, side effects, etc.

1. Therapeutic effect

First line drugs usually refer to anti tuberculosis drugs with good therapeutic effects, such as rifampicin tablets, ethambutol hydrochloride tablets, etc., which can kill Mycobacterium tuberculosis and have good therapeutic effects. Second line drugs usually refer to drugs that inhibit drug-resistant tuberculosis bacteria, such as pyrazinamide tablets and ethambutol hydrochloride tablets, which have relatively poor efficacy but can delay the development of drug resistance.

2. Side effects

The side effects of first-line drugs are relatively small, such as rifampicin tablets and ethambutol hydrochloride tablets, while the side effects of second-line drugs are relatively large, such as pyrazinamide tablets and ethambutol hydrochloride tablets, which may cause visual impairment.

In addition, the differences also include aspects such as price and drug resistance. It is recommended that patients choose appropriate medication under the guidance of a doctor for treatment, and not blindly use medication to avoid adverse reactions.
