Cefpodoxime sodium (R3763 sodium; U76253A) is a broad spectrum antibacterial agent that acts by binding to penicillin binding proteins (PBPs), thus inhibiting peptidoglycan synthesis, leading to disruption of bacterial cell wall biosynthesis. Cefpodoxime is active against most Gram-positive and Gram-negative organisms. Cefpodoxime Proxetil has been widely used to treat acute otitis media, pharyngitis, sinusitis, and gonorrhea.
| Toxicity/Toxicokinetics |
Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation Limited information indicates that cefpodoxime produces low levels in milk and is not be expected to cause any adverse effects in breastfed infants. Occasionally disruption of the infant's gastrointestinal flora, resulting in diarrhea or thrush have been reported with cephalosporins, but these effects have not been adequately evaluated. Cefpodoxime is acceptable in nursing mothers. ◉ Effects in Breastfed Infants Relevant published information was not found as of the revision date. ◉ Effects on Lactation and Breastmilk Hyperprolactinemia and bilateral galactorrhea occurred in a nonpregnant, 40-year-old woman taking cefpodoxime 200 mg twice daily for 2 days. Seven days after stopping the drug, galactorrhea ceased and the serum prolactin dropped markedly into the normal range. One month later it had dropped further. Because no other cause could be found, the authors determined that the galactorrhea and hyperprolactinemia were probably caused by cefpodoxime. A 22-year-old woman who had been taking slow-release venlafaxine 150 mg daily for 3 months reported bilateral breast engorgement and galactorrhea for 3 days after being prescribed cefpodoxime 200 mg twice daily for 14 days 2 weeks prior. Laboratory and head CT results were normal except for a slight elevation in alkaline phosphatase and an elevated serum prolactin level. Her galactorrhea began decreasing within 2 weeks and disappeared in 3 weeks with no change in venlafaxine dosage. Her serum prolactin level also returned to normal. The authors felt that her symptoms and hyperprolactinemia were probably caused by cefpodoxime. The prolactin level in a mother with established lactation may not affect her ability to breastfeed. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.2250 mL | 11.1252 mL | 22.2504 mL | |
| 5 mM | 0.4450 mL | 2.2250 mL | 4.4501 mL | |
| 10 mM | 0.2225 mL | 1.1125 mL | 2.2250 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
