Bio-Tetra
Bio-Tetra - General Information
A naphthacene antibiotic that inhibits amino acyl TRNA binding during protein synthesis.
Pharmacology of Bio-Tetra
Bio-Tetra is a short-acting antibiotic semisynthetically produced from chlortetracycline, which is derived from Streptomyces aureofaciens. Bio-Tetra inhibits cell growth by inhibiting translation. It binds to the 30S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome. This binding is reversible in nature.
Bio-Tetra for patients
When Actisite® fiber is in place, patients should avoid actions that may dislodge the fiber. Patients should receive the following instructions:
- Do not chew hard, crusty, or sticky foods.
- Do not brush or floss near any treated areas. (Continue to clean other teeth.)
- Do not engage in any other hygienic practices that could potentially dislodge the fibers.
- Do not probe at the treated area with tongue or fingers.
- Notify the dentist promptly if the fiber is dislodged or falls out before the scheduled recall visit, or if pain or swelling or other problems occur.
Bio-Tetra Interactions
Interactions
Interaction may occur with Antacids, Calcium supplements, Cholestyramine, Choline and
magnesium salicylates, Colestipol, Iron-containing drugs, Laxatives, Magnesium
salicylate: these drugs may decrease the potency of tetracyclines. Oral contraceptives
containing estrogen: tetracyclines may decrease the contraceptive effect and increase the
chance of unwanted pregnancy.
Bio-Tetra Contraindications
Actisite fiber should not be used in patients who are hypersensitive to any tetracycline.
Additional information about Bio-Tetra
Bio-Tetra Indication: Used to treat bacterial infections such as Rocky Mountain spotted fever, typhus fever, and tick fevers; upper respiratory infections; pneumonia; gonorrhea; amoebic infections; and urinary tract infections. It is also used to help treat severe acne and to treat trachoma (a chronic eye infection) and conjunctivitis (pinkeye). Bio-Tetra is often an alternative drug for people who are allergic to penicillin.
Mechanism Of Action: Bio-Tetra passively diffuses through porin channels in the bacterial membrane and reversibly binds to the 30S ribosomal subunit, preventing binding of tRNA to the mRNA-ribosome complex, and thus interfering with protein synthesis.
Drug Interactions: Not Available
Food Interactions: Avoid milk, calcium containing dairy products, iron, antacids, or aluminium salts 2 hours before or 6 hours after using antacids while on this medication.
Take on empty stomach: 1 hour before or 2 hours after meals.
Take with a full glass of water.
