Oxytetracycline Hydrochloride - Definition & Core Information

Oxytetracycline Hydrochloride (CAS No.: 2058-46-0) is a broad-spectrum tetracycline antibiotic, with the molecular formula C₂₂H₂₄N₂O₉·HCl and molecular weight 496.89 g/mol. It is a synthetic salt form of oxytetracycline, soluble in water and methanol, and stable under normal storage conditions (sealed, dry, away from light).

Key Uses

Oxytetracycline hydrochloride exerts antibacterial activity by inhibiting bacterial protein synthesis (binding to the 30S ribosomal subunit of susceptible bacteria, blocking aminoacyl-tRNA attachment), and it is active against a wide range of gram-positive and gram-negative bacteria, as well as some mycoplasma, chlamydia, and rickettsiae. Its main applications are categorized as follows:

1. Veterinary Medicine (Primary Application)

It is one of the most commonly used antibiotics in animal husbandry and aquaculture, indicated for:

Treatment of bacterial infections in livestock (cattle, sheep, pigs) such as respiratory tract infections (e.g., pasteurellosis), gastrointestinal infections (e.g., colibacillosis, salmonellosis), and genitourinary tract infections.
Management of bacterial diseases in poultry (chickens, ducks) including mycoplasmosis (chronic respiratory disease), pullorum disease, and fowl cholera.
Control of bacterial infections in aquaculture species (fish, shrimp) like Aeromonas hydrophila-induced septicemia and vibriosis.
Note: It is used in compliance with veterinary drug residue standards to avoid excessive use leading to bacterial resistance or residue in animal-derived foods.

2. Human Medicine (Limited, for Specific Indications)

Due to the rise of bacterial resistance, its clinical use in humans has decreased, but it is still prescribed for:

Treatment of rickettsial diseases (e.g., Rocky Mountain spotted fever, typhus).
Infections caused by susceptible bacteria (e.g., brucellosis, cholera) when other antibiotics are not suitable.
Acne vulgaris (topical or oral formulations for moderate inflammatory acne, as an alternative to other tetracyclines).

3. Other Applications

Agricultural field: Used as a bacteriostatic agent in some crop protection formulations (regulated strictly to prevent environmental resistance).
Laboratory research: Served as a selective agent in microbial culture media to inhibit the growth of susceptible bacteria.

Important Notes

Contraindications: Hypersensitivity to tetracyclines, pregnant women, and children under 8 years old (may cause tooth discoloration and bone development abnormalities).
Resistance: Long-term use may lead to the emergence of resistant strains, so it should be used under the guidance of a physician/veterinarian.
Drug interactions: Avoid concurrent use with metal ion-containing preparations (e.g., calcium, magnesium supplements) as they form insoluble complexes and reduce absorption.
