Food can slow or reduce absorption. High concentrations in tissues and fluids. | | distribution | Distributed throughout the body, including lungs, liver, and kidneys. Excreted in bile and urine. | | metabolism | Metabolized primarily in the liver, but some active metabolites may be formed. Some genetic polymorphisms may affect metabolism. | | elimination | Eliminated through the liver (bile) and kidneys (urine). Elimination can be prolonged in patients with renal impairment. |
| | suggested dosage | | oral | 250-500 mg every 6 hours or as directed by physician, adjust based on patient needs and infection. | | IV | Dosage and frequency by IV administration are determined by clinical conditions. Requires expert medical supervision. |
| | indications | Treats various bacterial infections, including respiratory tract infections, skin infections, and some sexually transmitted infections.

| | alternatives | | | contraindications | Known hypersensitivity to erythromycin or any macrolide antibiotics. Use with caution in patients with liver or kidney disease. | | interactions | Erythromycin can interact with several drugs, including certain medications used for heart conditions, blood thinners, and certain immunosuppressants. | | warnings precautions | Monitor liver function tests, especially in patients with pre-existing liver conditions. Patients with known allergies to erythromycin or similar antibiotics may show cross-reactivity. | | additional information | Different formulations and dosage forms are available.

The specific type should be consulted by a healthcare provider. | | patient profile | | | notes | These details are for general information only and should not be considered as a substitute for professional medical advice. |
| | 2 | | drug name | Clindamycin | | classification | Lincosamide antibiotic | | pharmacokinetics | | absorption | Well absorbed orally. Affected by presence of food. Achieves therapeutic levels in many tissues. | | distribution | Widely distributed in tissues, including bone, and penetrates into the meninges. Excreted in urine and bile. | | metabolism | Metabolized by the liver. Elimination can be prolonged with liver impairment. | | elimination | Eliminated primarily by the liver and kidneys, in urine. |
| | suggested dosage | | oral | 150-450 mg every 6 hours, or as directed by physician. |
| | indications | Treats various bacterial infections, including skin infections and bone infections. | | safety pregnancy | Use during pregnancy should be considered carefully, and only if the benefit outweighs the potential risk to the fetus.
