CEFOPROX CV Tablets / Suspension (Cefpodoxime proxetil + Clavulanate potassium)

Table of Content

The most important concern in the management of upper respiratory tract infections (URTIs) is antibiotic resistance.

Worldwide evidence suggests that inappropriate antibiotic use for non-severe URTIs, most of which are viral, adds to the overall burden of antibiotic resistance, a phenomenon which is becoming more prevalent. This resistance to antibiotics constitutes a major threat to public health. Nowadays, the resistance pattern for Cefpodoxime in India for various pathogens is on the increasing trend such as for E.coli (85%), K. pneumoniae (65%), S. aureus (60%), P. aeruginosa (100%), A. baumannii (67%) etc.

Over the last 15 years, β-lactamase enzymes that have an extended spectrum of activity (ESBL) against the majority of β-lactams, including cephalosporins have evolved. Combinations of β-lactam antibiotics and β-lactamase inhibitors have proved successful at treating infections caused by bacteria producing β -lactamases. Therefore, reintroduction of currently available penicillins and cephalosporins along with other agents such as β-lactamase inhibitors is an attractive opportunity for many reasons: Well established safety and efficacy profile, Antibiotic resistance. Convenience of use, and more essentially an understanding that using such combination empirically may help in not only overcome therapeutic failures due to resistant bacteria but will also delay resistance development in susceptible bacteria.

Hence the combination of Cefpodoxime (3rd generation cephalosporin) and Clavulanic acid (β-lactamase inhibitor) provides a solution for treatment of bacterial infections caused by beta lactam resistant pathogens.

CEFOPROX CV is a combination of a third generation β-lactam antibiotic Cefpodoxime proxetil with β-lactamase inhibitor Clavulanic acid.

Available as 325 mg tablet containing Cefpodoxime proxetil 200 mg along with a β-lactamase inhibitor Clavulanic acid 125 mg.

Also, available as Cefoprox CV Suspension, 50/31.25mg, 100/62.5 mg

CEFOPROX CV are a fixed-dose combination of cefpodoxime proxetil and potassium clavulanate. Cefpodoxime proxetil is an orally administered, extended-spectrum, semi-synthetic antibiotic of the cephalosporin class. The chemical name is (RS)-I(isopropoxycarbonyloxy) ethyl (+)-(6R,7R)-7--3-methoxymethyl-8-oxo-5-thia-I-azabicyclooct-2-ene-2-carboxylate. Its empirical formula is C21H27N5O9S2. The molecular weight of cefpodoxime proxetil is 557.6 and its structural formula is represented below:

Clavulanic acid is produced by the fermentation of Streptomyces clavuligerus. It is a beta-lactam structurally related to the penicillins and possesses the ability to inactivate a wide variety of beta-lactamases by blocking the active sites of these enzymes. Clavulanic acid is particularly active against the clinically important plasmid-mediated beta-lactamases frequently responsible for transferred drug resistance to penicillins and cephalosporins. The clavulanate potassium molecular formula is C8H8KNO5 and the molecular weight is 237.25. Chemically, clavulanate potassium is potassium (Z)-(2R,5R)-3-(2-hydroxyethylidene)-7-oxo-4-oxa-1-azabicyclo-heptane-2-carboxylate, and may be represented structurally as:


The bactericidal action of cefpodoxime results from inhibition of cell wall synthesis. Cefpodoxime is active against a wide-spectrum of Gram-positive and Gram-negative bacteria. Cefpodoxime has shown to be active against most strains of the following microorganisms, both in vitro and in clinical infections.

Cefpodoxime proxetil

Cefpodoxime proxetil is a prodrug that is absorbed from the gastrointestinal tract and de-esterified to its active metabolite, cefpodoxime.

Absorption: Bioavailability of cefpodoxime is 50% in fasting subjects and it increases in presence of food.

Distribution: Well distributed after oral administration. Cefpodoxime reaches therapeutic concentrations in respiratory tract and genito-urinary tracts and bile. Protein binding of cefpodoxime ranges from 20 to 30%. The plasma half-life of cefpodoxime is about 2 to 3 hours and is prolonged in patients with impaired renal function.

Excretion: Cefpodoxime is excreted unchanged in urine.

Clavulanate Potassium

Absorption: Well absorbed after oral administration

Distribution: Well distributed after oral administration. Protein binding of clavulanic acid is about 30%. The plasma half-life of clavulanic acid is one hour.

Excretion: About 60% of clavulanic acid is excreted unchanged in urine. The clavulanic acid component protects cefpodoxime from degradation by beta-lactamase enzymes and effectively extends the antibiotic spectrum of cefpodoxime to include many bacteria normally resistant to cefpodoxime and other beta-lactam antibiotics. Thus, possesses the distinctive properties of a broad-spectrum antibiotic and a beta-lactamase inhibitor.

Special Population

Renal Impairment

Elimination of cefpodoxime is reduced in patients with moderate to severe renal impairment (<50 mL/min creatinine clearance). In subjects with mild impairment of renal function (50 to 80 mL/min creatinine clearance), the average plasma half-life of cefpodoxime was 3.5 hours. In subjects with moderate (30 to 49 mL/min creatinine clearance) or severe renal impairment (5 to 29 mL/min creatinine clearance), the half-life increased to 5.9 and 9.8 hours, respectively. Approximately 23% of the administered dose was cleared from the body during a standard 3-hour hemodialysis procedure.

Hepatic Impairment

Absorption was somewhat diminished and elimination unchanged in patients with cirrhosis. The mean cefpodoxime T1/2 and renal clearance in cirrhotic patients were similar to those derived in studies of healthy subjects. Ascites did not appear to affect values in cirrhotic subjects. No dosage adjustment is recommended in this patient population.


Elderly subjects do not require dosage adjustments unless they have diminished renal function.


CEFOPROX CV are indicated for the treatment of patients with mild-to-moderate infections caused by susceptible strains of the designated microorganisms in the conditions listed below:

  • Acute otitis media caused by Streptococcus pneumoniae (excluding penicillin-resistant strains), Streptococcus pyogenes, Haemophilus influenzae (including beta-lactamase-producing strains), or Moraxella (Branhamella) catarrhalis (including beta-lactamase-producing strains).

Is contraindicated in patients with a known allergy to cephalosporin group of antibiotics.

Warnings and Precautions


Before therapy with cefpodoxime proxetil is instituted, careful inquiry should be made to determine whether the patient has had previous hypersensitivity reactions to cefpodoxime, other cephalosporins, penicillins, or other drugs.  If cefpodoxime is to be administered to penicillin-sensitive patients, caution should be exercised because cross-hypersensitivity among beta-lactam antibiotics has been clearly documented and may occur in up to 10% of patients with a history of penicillin allergy.  If an allergic reaction to cefpodoxime proxetil occurs, the drug should be discontinued.  Serious acute hypersensitivity reactions may require treatment with epinephrine and other emergency measures, including oxygen, intravenous fluids, intravenous antihistamine and airway management as clinically indicated.

Clostridium difficile-associated diarrhea (CDAD) has been reported with the use of nearly all antibacterial agents, including cefpodoxime proxetil, and may range in severity from mild diarrhoea to fatal colitis.  Treatment with antibacterial agents alters the normal flora of the colon, leading to the overgrowth of Clostridium difficile.

Drug interactions


Concomitant administration of high doses of antacids (sodium bicarbonate and aluminum hydroxide) or H2-blockers reduces peak plasma levels by 24–42% and the extent of absorption by 27–32%, respectively.  The rate of absorption is not altered by these concomitant medications. Oral anti-cholinergics (e.g., propantheline) delay peak plasma levels (47% increase in the Tmax), but do not affect the extent of absorption (AUC).


As with other beta-lactam antibiotics, renal excretion of cefpodoxime was inhibited by probenecid and resulted in an approximately 31% increase in the AUC and a 20% increase in peak cefpodoxime plasma levels.

Nephrotoxic Drugs

Although nephrotoxicity has not been noted when cefpodoxime proxetil was given alone, close monitoring of renal function is advised when cefpodoxime proxetil is administered concomitantly with compounds of known nephrotoxic potential.


The bioavailability increases if CEFOPROX CV Tablets are administered during meals.

Drug/Laboratory Test Interactions

A false-positive reaction for glucose in the urine may occur with Benedict’s or Fehling’s solutions or with copper sulfate test tablets, but not with tests based on enzymatic glucose oxidase reactions.

Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.

Sunset yellow (E110) may cause allergic reactions.

Renal impairment

For patients with severe renal impairment (<30 mL/min creatinine clearance), the dosing intervals should be increased to q24 hours. In patients maintained on hemodialysis, the dose frequency should be three times/week after hemodialysis. No data are available in case of pediatric patients with impaired renal function (please refer to DOSAGE AND ADMINISTRATION).

Hepatic impairment

No dose adjustment is recommended for patients with hepatic insufficiency.


Pregnancy category B. There are no adequate and well-controlled studies of cefpodoxime proxetil use in pregnant women. Because animal reproduction studies are not always predictive of human response, CEFOPROX CV Tablets should be used during pregnancy only if clearly needed.


Cefpodoxime Proxetil:  Cefpodoxime is excreted in human milk. 

Clavulanate Potassium: In studies, excretion of clavulanate potassium in milk occurs to a limited extent, the concentrations being lower than those detected in the serum. Because of the potential for serious reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use

Safety and efficacy of CEFOPROX CV in infants less than 2 months of age have not been established.

Geriatric Use

Dose adjustment in elderly patients with normal renal function is not necessary.

Effects on Ability to Drive and Use Machines

Cephalosporin-Class Labeling

In addition to the adverse reactions listed above, which have been observed in patients treated with cefpodoxime proxetil, the following adverse reactions and altered laboratory tests have been reported for cephalosporin-class antibiotics:

Adverse Reactions and Abnormal Laboratory Tests

Renal dysfunction, toxic nephropathy, hepatic dysfunction, including cholestasis, aplastic anemia, hemolytic anemia, serum sickness-like reactions, hemorrhage, agranulocytosis, and pancytopenia. 

Several cephalosporins have been implicated in triggering seizures, particularly in patients with renal impairment, when the dosage was not reduced. If seizures associated with drug therapy occur, the drug should be discontinued.  Anticonvulsant therapy can be given if clinically indicated.


In the event of a serious toxic reaction from overdosage, hemodialysis or peritoneal dialysis may aid in the removal of cefpodoxime from the body, particularly if renal function is compromised.

The toxic symptoms following an overdose of beta-lactam antibiotics may include nausea, vomiting, epigastric distress, and diarrhea.

In cases of overdosage, particularly in patients with renal insufficiency, encephalopathy may occur. The encephalopathy is usually reversible once cefpodoxime plasma levels have fallen.
