Actions and SpectrumÂ
Antibiotic medications like erythromycin lactobionate are used to treat bacterial infections. It works by attaching to the bacterial ribosome and preventing protein synthesis, which ultimately causes the death of the bacteria.Â
erythromycin lactobionate has a wide range of gram-positive bacteria it can kill, including Corynebacterium, Staphylococcus, and Streptococcus species. It also works against some Gram-negative microorganisms.Â

Black Box WarningÂ
erythromycin lactobionate has a black box warning because it has the potential to cause cardiac arrhythmias, especially when administered at large doses or in those with pre-existing cardiac problems.
When erythromycin lactobionate is used with specific medicines, such as some antiarrhythmic medications or some antipsychotic medications, this risk is raised.Â
erythromycin lactobionate carries a black box warning indicating the possibility of hepatotoxicity, or liver damage. Patients who take erythromycin lactobionate for an extended period or those who already have liver disease are at higher risk.Â
Contraindication/Caution:Â
Contraindication:Â
Caution:Â
Pregnancy warnings:    Â
Pregnancy category: BÂ Â
Lactation: Excretion into human milk is known Â
Pregnancy Categories:        Â
Category A: Studies that were well-controlled and met expectations revealed no risk to the fetus in either the first or second trimester.Â
Category B: There were lack of studies on pregnant women and no evidence of risk to the foetus in animal experiments.  Â
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.   Â
Category D: adequate data available with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.  Â
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.   Â
Category N: There is no data available for the drug under this category
PharmacologyÂ
A macrolide antibiotic called erythromycin lactobionate works by preventing bacterial protein synthesis. It specifically attaches to the bacterial ribosome’s 50S subunit to stop the peptide chain from lengthening during translation.Â
PharmacodynamicsÂ
Streptococcus, Staphylococcus, and Corynebacterium species are only a few of the many Gram-positive bacteria that erythromycin lactobionate is successful against. Additionally, it is effective against some gram-negative bacteria like Moraxella catarrhalis and Haemophilus influenzae.Â
A few processes, including changes to the target site, active drug efflux, or enzymatic drug modification, might lead to resistance to erythromycin lactobionate.Â
PharmacokineticsÂ
Absorption  Â
Given intravenously, erythromycin lactobionate is completely absorbed and quickly reaches high concentrations in the blood and tissues.Â
DistributionÂ
The body has erythromycin lactobionate in large amounts, including in the heart, liver, kidneys, lungs and other organs. It can pass through the placenta and end up in breast milk.Â
MetabolismÂ
The primary cytochrome P450 system enzyme, CYP3A4, in the liver is responsible for erythromycin lactobionate metabolism and its main metabolite of erythromycin lactobionate.Â
Elimination and excretionÂ
erythromycin lactobionate is eliminated in the bile and urine, with 2 to 5% of the medication leaving the body unchanged. erythromycin lactobionate has an elimination half-life of about 1.5 hours, however patients with compromised liver or kidney function may experience a longer half-life.Â
Administration: Â
The medication erythromycin lactobionate is given intravenously. Â
To reduce the risk of infusion-related responses, erythromycin lactobionate should be infused gradually over a minimum of 20 to 30 minutes. In the same syringe or infusion bag, the medication should not be mixed with any other medications.Â
