Tuberculosis (TB) remains a major global health issue, with millions of people diagnosed every year.
Treatment for TB is primarily divided into two categories: AFB (Mycobacterial) Drug 1st line and 2nd line therapies. These two groups of drugs are vital in treating both standard and drug-resistant TB cases, with first-line drugs being the most commonly used, and second-line drugs reserved for more complex cases, such as multidrug-resistant TB (MDR-TB).
AFB (Mycobacterial) drug treatments are divided into 1st and 2nd line options to manage tuberculosis (TB) infections effectively. 1st line drugs are the primary choice for treating drug-susceptible TB and include Isoniazid (INH), Rifampicin (RIF), Ethambutol (EMB), Pyrazinamide (PZA), and Streptomycin (SM). These medications work by disrupting vital bacterial processes, such as inhibiting cell synthesis and protein synthesis. Given together, these drugs prevent resistance and reduce treatment time, generally requiring 6-9 months for a complete course. Isoniazid and Rifampicin are especially powerful, while Pyrazinamide is particularly effective in acidic environments, which makes it suitable for fighting bacteria within immune cells.
When TB bacteria develop resistance to 1st line drugs, 2nd line drugs are used, especially in cases of multidrug-resistant (MDR) or extensively drug-resistant TB (XDR-TB). These drugs include Fluoroquinolones (like Levofloxacin and Moxifloxacin), injectable agents (such as Amikacin, Kanamycin, and Capreomycin), Ethionamide, Prothionamide, Cycloserine, Para-Aminosalicylic Acid (PAS), and Linezolid. Although effective, 2nd line drugs are more potent and often have a higher risk of side effects, so they’re reserved for more resistant TB cases. Treatment with 2nd line drugs is usually longer, lasting from 18 to 24 months, depending on resistance severity and the patient’s response. The choice of treatment is tailored carefully to each case, ensuring optimal management and minimizing potential adverse effects.
Tuberculosis is a serious infectious disease that primarily affects the lungs but can also spread to other parts of the body, including the kidneys, spine, and brain. Treatment is essential for curing the infection, preventing its spread to others, and avoiding complications, such as drug-resistant strains of TB.
Importance of First-Line Drugs:
Highly Effective: First-line drugs have a high success rate in treating drug-susceptible TB.
Prevention of Resistance: Taking these medications as prescribed reduces the risk of developing drug-resistant strains.
Faster Recovery: A proper regimen can cure TB within 6 to 9 months.

D) Comprehensive Care: From diagnosis to treatment monitoring, we provide thorough support throughout the entire treatment journey, ensuring a smooth recovery process.
Yes, the vast majority of TB cases can be cured with 1st line drugs, provided they are taken correctly for the full duration of the prescribed course.
1st line TB drugs are the primary medications used to treat regular, drug-susceptible TB infections. These drugs are effective and have fewer side effects compared to 2nd line drugs, which are used for drug-resistant TB cases and have more side effects and a longer treatment duration.
Treatment with 1st line drugs typically lasts between 6 to 9 months. 2nd line drugs for drug-resistant TB can extend treatment duration to 18 to 24 months or longer, depending on the patient's response to therapy.
If resistance to 1st line drugs occurs, your doctor will prescribe 2nd line drugs to treat the infection. This will require longer treatment and more monitoring.
