Tetracycline HCl belongs to the pharmacological group of antibacterial agents, specifically tetracyclines (ATC code: J01A A07).

• Pharmacodynamics: Tetracycline HCl exerts its antimicrobial effect by inhibiting bacterial protein synthesis, thereby preventing bacterial growth and replication. It is active against a broad spectrum of Gram-positive and Gram-negative bacteria, as well as certain protozoa.
• Pharmacokinetics: Following oral administration, tetracycline HCl is well-absorbed from the gastrointestinal tract. It is distributed widely in various body tissues and fluids, achieving therapeutic concentrations in the skin, respiratory tract, and urinary tract. Tetracycline HCl is primarily excreted unchanged in the urine via renal filtration and tubular secretion.

Tetracycline HCl is indicated for the treatment of various infections caused by susceptible pathogens, including:

• Respiratory tract infections (e.g., pneumonia, bronchitis)
• Skin and soft tissue infections
• Urinary tract infections
• Sexually transmitted infections (e.g., chlamydia, gonorrhea)
• Acne vulgaris
• Rickettsial infections
• Helicobacter pylori eradication in combination therapy for peptic ulcer disease

Tetracycline HCl is contraindicated in individuals with a known hypersensitivity to tetracyclines or any component of the formulation. It should not be used in children under 8 years of age or in pregnant women due to the risk of tooth discoloration and bone development impairment.

Tetracycline HCl may interact with various medications, including antacids, iron supplements, and oral contraceptives, potentially reducing its absorption or efficacy. Caution is advised when co-administering tetracycline HCl with such drugs.

Tetracycline HCl tablets and capsules should be taken orally with a full glass of water, preferably on an empty stomach, at least 1 hour before or 2 hours after meals, to enhance absorption and minimize gastrointestinal side effects.

The recommended dosage of Tetracycline HCl varies depending on the type and severity of the infection, as well as patient factors such as age, weight, and renal function. Healthcare providers will determine the appropriate dose and duration of therapy based on clinical judgment and guidelines.

Common side effects of Tetracycline HCl may include gastrointestinal disturbances (e.g., nausea, vomiting, diarrhea), photosensitivity, and fungal overgrowth (e.g., oral or vaginal candidiasis). Serious adverse effects such as hepatotoxicity and pseudomembranous colitis are rare but require medical attention if they occur.

Tetracycline HCl tablets and capsules should be stored at room temperature (15-30°C) in a dry place, protected from light and moisture.

Tetracycline HCl is contraindicated during pregnancy and breastfeeding due to the risk of adverse effects on fetal tooth development and bone growth. Alternative antibiotics should be considered in these situations.

Tetracycline HCl does not typically impair cognitive or motor functions. However, patients should be cautious when driving or operating machinery, especially if they experience dizziness or visual disturbances.

In the event of overdose, supportive measures should be initiated as needed. Overdose symptoms may include gastrointestinal symptoms and intracranial hypertension.

Tetracycline HCl is an important antibiotic for the treatment of various bacterial infections. By understanding its mechanisms of action, indications, dosage, and precautions, patients and healthcare providers can work together to achieve optimal treatment outcomes. Always consult a healthcare provider for personalized medical advice.
