What is Cotrimoxazole Ratiopharm?

Cotrimoxazole Ratiopharm and Trimethoprim (Cotrimoxazole Ratiopharm) combination is used to treat infections such as urinary tract infections, middle ear infections (otitis media), bronchitis, traveler's diarrhea, and shigellosis (bacillary dysentery). Cotrimoxazole Ratiopharm and Trimethoprim (Cotrimoxazole Ratiopharm) is also used to prevent or treat Pneumocystis jiroveci pneumonia or Pneumocystis carinii pneumonia (PCP), a very serious kind of pneumonia. This type of pneumonia occurs more commonly in patients whose immune systems are not working normally, such as cancer patients, transplant patients, and patients with acquired immune deficiency syndrome (AIDS).

Cotrimoxazole Ratiopharm and Trimethoprim (Cotrimoxazole Ratiopharm) combination is an antibiotic. It works by eliminating the bacteria that cause many kinds of infections. Cotrimoxazole Ratiopharm and Trimethoprim (Cotrimoxazole Ratiopharm) will not work for colds, flu, or other virus infections.

Cotrimoxazole Ratiopharm and Trimethoprim (Cotrimoxazole Ratiopharm) is available only with your doctor's prescription.

Cotrimoxazole Ratiopharm indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Cotrimoxazole Ratiopharm and other antibacterial drugs, Cotrimoxazole Ratiopharm should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Urinary Tract Infections

For the treatment of urinary tract infections due to susceptible strains of the following organisms: Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis, and Proteus vulgaris. It is recommended that initial episodes of uncomplicated urinary tract infections be treated with a single effective antibacterial agent rather than the combination.

Acute Otitis Media

For the treatment of acute otitis media in pediatric patients due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when, in the judgment of the physician, Cotrimoxazole Ratiopharm offers some advantage over the use of other antimicrobial agents. To date, there is limited data on the safety of repeated use of Cotrimoxazole Ratiopharm in pediatric patients under two years of age. Cotrimoxazole Ratiopharm is not indicated for prophylactic or prolonged administration in otitis media at any age.

Acute Exacerbations of Chronic Bronchitis in Adults

For the treatment of acute exacerbations of chronic bronchitis due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when, a physician deems that, Cotrimoxazole Ratiopharm could offer some advantage over the use of a single antimicrobial agent.

Travelers' Diarrhea in Adults

For the treatment of travelers' diarrhea due to susceptible strains of enterotoxigenic E. coli.

Shigellosis

For the treatment of enteritis caused by susceptible strains of Shigella flexneri and Shigella sonnei when antibacterial therapy is indicated.

Pneumocystis jiroveci Pneumonia

For the treatment of documented Pneumocystis jiroveci pneumonia. For prophylaxis against Pneumocystis jiroveci pneumonia in individuals who are immunosuppressed and considered to be at an increased risk of developing Pneumocystis jiroveci pneumonia.

How should I use Cotrimoxazole Ratiopharm?

Use Cotrimoxazole Ratiopharm suspension as directed by your doctor. Check the label on the medicine for exact dosing instructions.

Ask your health care provider any questions you may have about how to use Cotrimoxazole Ratiopharm suspension.

Uses of Cotrimoxazole Ratiopharm in details

There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease.

Potential for Cotrimoxazole Ratiopharm to Affect Other Drugs

Trimethoprim (Cotrimoxazole Ratiopharm) is an inhibitor of CYP2C8 as well as OCT2 transporter. Cotrimoxazole Ratiopharm is an inhibitor of CYP2C9. Caution is recommended when Cotrimoxazole Ratiopharm is co-administered with drugs that are substrates of CYP2C8 and 2C9 or OCT2.

In elderly patients concurrently receiving certain diuretics, primarily thiazides, an increased incidence of thrombocytopenia with purpura has been reported.

It has been reported that Cotrimoxazole Ratiopharm may prolong the prothrombin time in patients who are receiving the anticoagulant warfarin (a CYP2C9 substrate). This interaction should be kept in mind when Cotrimoxazole Ratiopharm is given to patients already on anticoagulant therapy, and the coagulation time should be reassessed.

Cotrimoxazole Ratiopharm may inhibit the hepatic metabolism of phenytoin (a CYP2C9 substrate). Cotrimoxazole Ratiopharm, given at a common clinical dosage, increased the phenytoin half-life by 39% and decreased the phenytoin metabolic clearance rate by 27%. When administering these drugs concurrently, one should be alert for possible excessive phenytoin effect.

Sulfonamides can also displace methotrexate from plasma protein binding sites and can compete with the renal transport of methotrexate, thus increasing free methotrexate concentrations.

There have been reports of marked but reversible nephrotoxicity with coadministration of Cotrimoxazole Ratiopharm and cyclosporine in renal transplant recipients.

Increased digoxin blood levels can occur with concomitant Cotrimoxazole Ratiopharm therapy, especially in elderly patients. Serum digoxin levels should be monitored.

Increased Cotrimoxazole Ratiopharm blood levels may occur in patients who are also receiving indomethacin.

Occasional reports suggest that patients receiving pyrimethamine as malaria prophylaxis in doses exceeding 25 mg weekly may develop megaloblastic anemia if Cotrimoxazole Ratiopharm is prescribed.

The efficacy of tricyclic antidepressants can decrease when coadministered with Cotrimoxazole Ratiopharm.

Cotrimoxazole Ratiopharm potentiates the effect of oral hypoglycemics that are metabolized by CYP2C8 (e.g., pioglitazone, repaglinide, and rosiglitazone) or CYP2C9 (e.g., glipizide and glyburide) or eliminated renally via OCT2 (e.g., metformin). Additional monitoring of blood glucose may be warranted.

In the literature, a single case of toxic delirium has been reported after concomitant intake of Cotrimoxazole Ratiopharm and amantadine (an OCT2 substrate). Cases of interactions with other OCT2 substrates, memantine and metformin, have also been reported.

In the literature, three cases of hyperkalemia in elderly patients have been reported after concomitant intake of Cotrimoxazole Ratiopharm and an angiotensin converting enzyme inhibitor.

Drug/Laboratory Test Interactions

Cotrimoxazole Ratiopharm, specifically the Trimethoprim (Cotrimoxazole Ratiopharm) component, can interfere with a serum methotrexate assay as determined by the competitive binding protein technique (CBPA) when a bacterial dihydrofolate reductase is used as the binding protein. No interference occurs, however, if methotrexate is measured by a radioimmunoassay (RIA).

The presence of Cotrimoxazole Ratiopharm and Trimethoprim (Cotrimoxazole Ratiopharm) may also interfere with the Jaffé alkaline picrate reaction assay for creatinine, resulting in overestimations of about 10% in the range of normal values.
