The Brand Name: Claforan
While cefotaxime is the official generic name of the drug, it was originally marketed and is most widely recognized under the brand name Claforan. The brand name is a proprietary term used by the manufacturer, while the generic name is the non-proprietary, scientific name of the active ingredient. Even though generic versions of cefotaxime are now commonly available, the brand name Claforan is still frequently used in clinical practice and in medical literature. In some international markets, other trade names such as Cefotax, Oritaxim, and Taxime may also be used, though availability can vary by region.
Understanding Cefotaxime
Cefotaxime belongs to the class of third-generation cephalosporin antibiotics, which are bactericidal agents used to treat a broad spectrum of bacterial infections. These drugs work by inhibiting the synthesis of the bacterial cell wall, leading to the death of the bacterial cells.
Clinical Uses and Spectrum of Activity
Cefotaxime is a versatile antibiotic employed against a variety of serious and potentially life-threatening bacterial infections. Its broad-spectrum activity includes both Gram-positive and Gram-negative bacteria, as well as some anaerobes.
Common indications for cefotaxime include:
- Lower Respiratory Tract Infections: Such as pneumonia caused by susceptible organisms.
- Central Nervous System (CNS) Infections: Including meningitis and ventriculitis caused by specific susceptible bacteria.
- Intra-abdominal Infections: Peritonitis and other abdominal infections.
- Genitourinary Infections: Including complicated urinary tract infections (UTIs) and uncomplicated gonorrhea.
- Gynecologic Infections: Such as pelvic inflammatory disease.
- Bone and Joint Infections: Caused by susceptible bacteria.
- Skin and Skin Structure Infections: Used for a range of skin infections.
- Sepsis: For severe, systemic bacterial infections.
- Surgical Prophylaxis: To prevent infections after certain types of surgeries, particularly cesarean sections and gastrointestinal procedures.
Mechanism of Action: How Cefotaxime Works
The bactericidal action of cefotaxime stems from its ability to disrupt the construction of the bacterial cell wall. Specifically, it works by binding to and inhibiting penicillin-binding proteins (PBPs), which are enzymes crucial for the final steps of peptidoglycan synthesis—the primary component of the bacterial cell wall. By interfering with this process, the structural integrity of the cell wall is compromised, leading to cell lysis and death. It is also known for its stability against many common beta-lactamase enzymes produced by bacteria, which are a mechanism of antibiotic resistance.
Administration and Dosing
Cefotaxime is administered by healthcare professionals through either intramuscular (IM) or intravenous (IV) injection. The specific dosage and frequency depend on factors like the type and severity of the infection, the patient's age and weight, and renal function. For severe infections, IV administration is generally preferred, often through a slower infusion over 20-60 minutes. Due to its short half-life of around one hour, cefotaxime often requires more frequent dosing compared to some other cephalosporins.
Cefotaxime vs. Ceftriaxone: A Clinical Comparison
Cefotaxime is often compared to another third-generation cephalosporin, ceftriaxone (brand name Rocephin). While both have a similar antibacterial spectrum, there are notable differences in their pharmacokinetics, as detailed in the table below:
| Feature | Cefotaxime (Claforan) | Ceftriaxone (Rocephin) |
|---|---|---|
| Half-life | Short (~1 hour) | Long (~8.8 hours) |
| Dosing Frequency | Multiple daily doses (e.g., every 4-8 hours) | Often once-daily dosing |
| Protein Binding | Low (~35%) | High (~95%) |
| Biliary Excretion | Low (~10%) | High (~40%) |
| Biliary Concerns | Less likely to cause pseudolithiasis/cholelithiasis | Associated with potential biliary pseudolithiasis |
| Convenience | Less convenient due to more frequent dosing | More convenient due to once-daily dosing |

Potential Side Effects and Precautions
Like all medications, cefotaxime can cause side effects. The most common are localized reactions at the injection site, including pain, swelling, and redness. Other frequent side effects include gastrointestinal issues like diarrhea, nausea, and vomiting.
More serious side effects can occur, including:
- Severe Allergic Reactions: A rare but life-threatening possibility, especially in those with a history of penicillin or cephalosporin allergies.
- C. difficile-associated diarrhea: A potentially severe form of colitis that can occur during or after antibiotic treatment.
- Neurological Effects: High doses, particularly in patients with kidney problems, can lead to encephalopathy, confusion, and seizures.
- Blood Disorders: Rare cases of neutropenia, leukopenia, or agranulocytosis have been reported, necessitating blood count monitoring during prolonged therapy.
It is important to use caution in patients with a history of gastrointestinal disease, especially colitis, and to adjust dosage in those with renal impairment. Cefotaxime should not be mixed with aminoglycoside solutions.
Conclusion
For those asking "What is another name for cefotaxime?", the primary brand name is Claforan. As a potent third-generation cephalosporin, cefotaxime plays a crucial role in treating a variety of serious bacterial infections, from meningitis to pneumonia and septicemia. Its unique pharmacokinetic profile and broad spectrum of activity make it a valuable tool in a healthcare provider's arsenal, although potential side effects and differences from similar drugs like ceftriaxone must be considered. Understanding both its generic and brand identities is essential for proper identification and effective communication in a clinical setting. For more detailed medical information, reliable sources like the US National Library of Medicine (NIH) offer extensive drug information on cefotaxime.
