| drugs | | 1 | | name | Erythromycin | | classification | Macrolide antibiotic | | pharmacokinetics | Erythromycin is primarily absorbed from the gastrointestinal tract. Absorption is variable and can be affected by food. Peak plasma levels are reached within 1-4 hours. Erythromycin is widely distributed throughout tissues and fluids, including lungs, sinuses, and bones. It is metabolized by the liver, and some metabolites may accumulate in patients with hepatic impairment. Elimination is primarily via the liver, with a half-life of approximately 6-12 hours. Multiple formulations exist (e.g., oral, intravenous, topical). | | suggested dosage | Dosage varies depending on the indication and formulation. Consult a healthcare professional for specific recommendations. | | indications | Erythromycin is indicated for a variety of bacterial infections, including respiratory tract infections, skin and soft tissue infections, and some sexually transmitted infections. It is also used to treat atypical pneumonia caused by *Mycoplasma pneumoniae* and *Chlamydia pneumoniae*. Specific indications may vary by formulation. Consult a healthcare professional for specific recommendations. | | safety in pregnancy | Erythromycin is generally considered safe for use during pregnancy, but careful consideration should be given to potential maternal and fetal effects, and the specific indication should guide the decision to prescribe. Consult with a healthcare professional. | | safety in breastfeeding | Erythromycin is excreted into breast milk in low concentrations and is generally considered safe for use during breastfeeding. However, consult with a healthcare professional. | | side effects | Common side effects include nausea, vomiting, diarrhea, abdominal pain, and flatulence. More serious, but less frequent, side effects may include jaundice, hepatitis, and potentially serious cardiac arrhythmias. Patients with underlying cardiac conditions, liver disease, or renal insufficiency require special monitoring and caution when treated with erythromycin. | | alternatives | | | contraindications | Hypersensitivity to macrolides; severe hepatic impairment; concomitant use with certain drugs, such as terfenadine or astemizole (which can cause potentially fatal cardiac arrhythmias). Consult a healthcare professional. | | interactions | Erythromycin can interact with numerous drugs, including anticoagulants, calcium channel blockers, digoxin, theophylline, and others. Consult a healthcare professional to assess potential drug interactions. | | warnings and precautions | Erythromycin can prolong the QT interval in some individuals. This is a particular concern in patients with underlying cardiac conditions. Careful monitoring of ECG is recommended in such cases. Assess renal function, especially in patients with underlying kidney disease. | | additional information | Available in various dosage forms like oral tablets, capsules, intravenous, and topical preparations. | | special considerations for patient age and weight | Dosage needs to be adjusted based on the specific indication and renal function, not simply age and weight. Consult a physician. |
| | 2 | | name | Azithromycin | | classification | Macrolide antibiotic | | pharmacokinetics | Azithromycin is well-absorbed orally and has a long half-life, allowing for once-daily dosing. It is widely distributed in tissues and fluids. It is primarily eliminated through the liver. Absorption can be affected by food, though usually not to a large degree. | | suggested dosage | Dosage varies depending on the indication and formulation. Consult a healthcare professional for specific recommendations. | | indications | Azithromycin is indicated for a variety of bacterial infections, including respiratory tract infections, skin and soft tissue infections, and some sexually transmitted infections. Consult a healthcare professional for specific recommendations. | | safety in pregnancy | Consult with a healthcare professional for potential risks and benefits of Azithromycin during pregnancy. | | safety in breastfeeding | Consult with a healthcare professional regarding the safety of Azithromycin while breastfeeding. | | side effects | Common side effects may include nausea, vomiting, diarrhea, abdominal pain. Less common, but potentially serious side effects may include liver dysfunction, and cardiac arrhythmias. Consult with your healthcare professional. | | contraindications | Hypersensitivity to azithromycin or macrolides; severe hepatic impairment; consult with a healthcare professional. | | alternatives | | | interactions | Azithromycin can interact with numerous drugs, including anticoagulants, certain antifungals, and others. Consult a healthcare professional. | | warnings and precautions | Monitor renal function, especially in patients with pre-existing kidney disease. Carefully monitor patients with cardiac conditions. Evaluate for possible QT interval prolongation. | | additional information | Available in oral tablet and IV forms. | | special considerations for patient age and weight | Dosage needs to be adjusted based on the specific indication and renal function, not simply age and weight. Consult a physician. |
