Pharmacology of Eromycin DS Tablet

Erythromycin blocks the translocation process, which stops microsomal protein synthesis in sensitive organisms. These organisms have specific binding to the 50S subunit or the 70S ribosome, but no binding to the stable 80S mammalian ribosome. Erythromycin is effective against a wide range of Gram-positive and Gram-negative bacteria, as well as mycoplasmas and chlamydia. Because the base of erythromycin is destroyed by acid, it is given in the form of a stable ester. The presence of food reduces the rate of absorption of the base and esters. In the gut, the stearate is hydrolyzed, and the free erythromycin is absorbed. Peak serum concentrations of 0.9 to 1.4 or 0.4 to 1.8 mg/ml respectively are achieved in 1 to 4 hours after an oral dose of 500 mg of the base of stearate. The serum half-life ranges from 1.2 to 4 hours. The half-life in oliguria patients is roughly 5 hours.

Erythromycin is broadly dispersed throughout bodily tissue and fluids, with some retention in the liver and spleen. Erythromycin base has a 73 percent protein binding rate. When the meninges become inflamed, erythromycin enters the cerebrospinal fluid. It also passes through the placenta and is secreted in breast milk. The unmodified active ingredient is excreted in substantial amounts in the bile, and 5 to 15% of the erythromycin dose is eliminated in the urine.

Interaction of Eromycin DS Tablet

According to new research, using erythromycin in individuals who are taking a high dose of theophylline may result in a rise in serum theophylline levels and probable theophylline toxicity. In such circumstances, theophylline dosage should be lowered.

Contraindications

Erythromycin hypersensitivity is known.

Side effects of Eromycin DS Tablet

Gastrointestinal: Abdominal cramp & discomfort, nausea, vomiting & diarrhea. Hypersensitivity reaction may also be responsible for hepatotoxicity sometimes in patients receiving Erythromycin or its derivatives.

Pregnancy & Lactation

• Use in pregnancy: A-Mycin (Erythromycin) crosses the placenta. Fetal plasma concentrations are variously stated to the 5 to 20% of these in the mother.
• Use in lactation: It is readily excreted in breast milk.

Precautions & Warnings

Erythromycin should be used with care in patients with existing hepatic impairment. It has been suggested that Erythromycin should be used with care in patients with a history of arrhythmia.

Storage Conditions

Keep the temperature below 25°C and away from light and moisture. Keep out of children's reach.
