Indications
A-Tetra 500 is used to treat various infections, including rickettsial infections like Rocky Mountain spotted fever and scrub typhus. A-Tetra 500 also treats infections caused by Mycoplasma pneumoniae, which is common in places like barracks. A-Tetra 500 is effective against chlamydial infections, including psittacosis (a disease caught from infected birds). A-Tetra 500 helps in treating non-gonococcal urethritis, Lyme disease, brucellosis, and other infections like cholera and relapsing fever. A-Tetra 500 is also used for treating acne, urinary tract infections, bronchitis, pelvic inflammatory disease, and travelers’ diarrhea. A-Tetra 500 is sometimes used for syphilis in penicillin-allergic patients and for anaerobic infections.
Pharmacology
A-Tetra 500 works by stopping bacteria from making proteins, which is crucial for their growth. The drug is absorbed into the body and binds to bacteria inside, preventing them from producing proteins. A-Tetra 500 is effective against many bacteria, but some bacteria, like certain staph and strep strains, may resist A-Tetra 500. A-Tetra 500 is still used for some urinary tract infections and infections caused by Brucella species, cholera, and Vibrio vulnificus. Tetracycline is not well absorbed in the body, with 60-80% of the dose becoming available. A-Tetra 500 is widely spread in body tissues and fluids and has a half-life of about 12 hours. A-Tetra 500 is removed from the body through urine and feces.
Dosage & Administration
Adults: The usual dose is 1-2 grams per day, split into 2-4 doses. Children over 8 years: The usual dose is 25-50 mg/kg daily, divided into 2-4 doses. Alternatively, some doctors suggest children get 0.6-1.2 grams per square meter of body surface daily.
For acne: 250 mg four times a day or 500 mg twice daily for 1 week, then 125-250 mg for several weeks. For staph infections: 1-2 grams per day for 10-14 days. For streptococcal infections: 1-2 grams per day for 10 days. For brucellosis: 500 mg four times a day with streptomycin for 1 week, then continue without streptomycin. For syphilis: 30-40 grams in divided doses over 10-15 days.
Interaction
Its absorption may be reduced by antacids containing aluminum, calcium, magnesium, or iron, and by certain other medications like kaolin-pectin, bismuth subsalicylate, and sucralfate. A-Tetra 500 may reduce the effect of penicillin and interfere with birth control pills. A-Tetra 500 can increase the effect of blood thinners, and its side effects may worsen if taken with diuretics or certain other drugs. A-Tetra 500 may also increase the effects of insulin or sulfonylureas in diabetic patients.
