Mechanism of Action

Tetracycline Hydrochloride works by inhibiting bacterial protein synthesis. It binds reversibly to the 30S subunit of the bacterial ribosome, preventing the attachment of transfer RNA (tRNA) to the ribosome-mRNA complex. This action blocks the addition of new amino acids to the growing protein chain, thereby inhibiting bacterial growth.

Tetracycline is primarily bacteriostatic, meaning it prevents bacteria from multiplying and allows the body’s immune system to eliminate the infection. Its broad-spectrum activity makes it effective against a wide variety of organisms.

Dosage and Administration

A-Tetra Capsule 500 mg should be taken orally as prescribed by a healthcare professional. It is usually recommended to take the capsule on an empty stomach, either one hour before or two hours after meals, to enhance absorption.

The capsule should be swallowed whole with a full glass of water while sitting or standing upright to reduce the risk of esophageal irritation. Patients should complete the full prescribed course of treatment, even if symptoms improve earlier.

Precautions and Warnings

• Not recommended for use in pregnant or breastfeeding women, as tetracycline may affect fetal and infant development.

• Contraindicated in children below 8 years of age due to the risk of tooth discoloration and impaired bone growth.

• Use with caution in patients with liver or kidney impairment.

• Avoid concurrent intake with milk, antacids, or iron supplements, as these may reduce absorption.

Possible Side Effects

Common side effects may include:

• Nausea or vomiting

• Diarrhea

• Abdominal discomfort

• Photosensitivity reactions

Rare but serious adverse effects include allergic reactions and liver dysfunction. Medical advice should be sought if severe side effects occur.
