Introduction
A tetracycline analog isolated from the actinomycete streptomyces rimosus and used in a wide variety of clinical conditions.
Uses
Zenoxy Capsule 250 mg is a tetracycline antibiotic used to treat a wide variety of susceptible bacterial infections.
Zenoxy Capsule 250 mg is indicated for treatment of infections caused by a variety of Gram positive and Gram negative microorganisms including Mycoplasma pneumoniae, Pasteurella pestis, Escherichia coli, Haemophilus influenzae (respiratory infections), and Diplococcus pneumoniae.
Associated Conditions
Pharmacodynamics
Zenoxy Capsule 250 mg is known as a broad-spectrum antibiotic due to its activity against such a wide range of infections. It was the second of the tetracyclines to be discovered. Zenoxy Capsule 250 mg, like other tetracyclines, is used to treat many infections common and rare. Its better absorption profile makes it preferable to tetracycline for moderately severe acne, but alternatives sould be sought if no improvement occurs by 3 months.
Mechanism of Action
Zenoxy Capsule 250 mg 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. The binding is reversible in nature. Zenoxy Capsule 250 mg is lipophilic and can easily pass through the cell membrane or passively diffuses through porin channels in the bacterial membrane.
Absorption
Readily absorbed following oral administration.
Toxicity
Adverse effects may include stomach or bowel upsets and rarely allergic reactions. Very rarely severe headache and vision problems may be signs of dangerous intracranial hypertenion.
