Dosage of Nexmezol in details

The dose of a drug and dosage of the drug are two different terminologies. Dose is defined as the quantity or amount of medicine given by the doctor or taken by the patient at a given period. Dosage is the regimen prescribed by the doctor about how many days and how many times per day the drug is to be taken in specified dose by the patient. The dose is expressed in mg for tablets or gm, micro gm sometimes, ml for syrups or drops for kids syrups. The dose is not fixed for a drug for all conditions, and it changes according to the condition or a disease. It also changes on the age of the patient.

What other drugs will affect Nexmezol?

Nexmezol should not be taken together with atazanavir (Reyataz) or nelfinavir (Viracept). Tell your doctor if you are taking either of these medications to treat HIV or AIDS.

Tell your doctor about all other medicines you use, especially:

This list is not complete and other drugs may interact with Nexmezol. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.

Nexmezol interactions

Interactions are the effects that happen when the drug is taken along with the food or when taken with other medications. Suppose if you are taking a drug Nexmezol, it may have interactions with specific foods and specific medications. It will not interact with all foods and medications. The interactions vary from drug to drug. You need to be aware of interactions of the medicine you take. Most medications may interact with alcohol, tobacco, so be cautious.

Nexmezol is extensively metabolized in the liver by CYP2C19 and CYP3A4.

In vitro and in vivo studies have shown that Nexmezol is not likely to inhibit CYPs 1A2, 2A6, 2C9, 206, 2E1 and 3A4. No clinically relevant interactions with drugs metabolized by these CYP enzymes would be expected. Drug interaction studies have shown that Nexmezol does not have any clinically significant interactions with phenytoin, warfarin, quinidine, clarithromycin or amoxicillin. Post-marketing reports of changes in prothrombin measures have been received among patients on concomitant warfarin and Nexmezol therapy. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Patients treated with proton pump inhibitors and warfarin concomitantly may need to be monitored for increases in INR and prothrombin time.

Nexmezol may potentially interfere with CYP2C19, the major Nexmezol metabolizing enzyme. Coadministration of Nexmezol 30 mg and diazepam, a CYP2C19 substrate, resulted in a 45% decrease in clearance of diazepam. Increased plasma levels of diazepam were observed 12 hours after dosing and onwards. However, at that time, the plasma levels of diazepam were below the therapeutic interval, and thus this interaction is unlikely to be of clinical relevance.

Concomitant administration of Nexmezol and a combined inhibitor of CYP2C19 and CYP3A4, such as voriconazole, may result in more than doubling of the Nexmezol exposure. Dose adjustment of Nexmezol is not normally required for the recommended doses. However, in patients who may require higher doses, dose adjustment may be considered.

Nexmezol acts as an inhibitor of CYP2C19. Nexmezol given in doses of 40 mg daily for one week to 20 healthy subjects in cross-over study, increased Cmax and AUC of cilostazol by 18% and 26% respectively. Cmax and AUC of one of its active metabolites, 3,4-dihydro-cilostazol, which has 4-7 times the activity of cilostazol, were increased by 29% and 69% respectively. Co-administration of cilostazol with Nexmezol is expected to increase concentrations of cilostazol and its above mentioned active metabolite. Therefore a dose reduction of cilostazol from 100 mg b.i.d. to 50 mg b.i.d. should be considered.

Co-administration of' oral contraceptives, diazepam, phenytoin, or quinidine did not seen to change the pharmacokinetic profile of Nexmezol.

Antiretroviral Agents: Concomitant use of atazanavir and nelfinavir with proton pump inhibitors is not recommended. Co-administration of atazanavir with proton pump inhibitors is expected to substantially decrease atazanavir plasma concentrations and thereby reduce its therapeutic effect.

Nexmezol has been reported to interact with some antiretroviral drugs. The clinical importance and the mechanisms behind these interactions are not always known. Increased gastric pH during Nexmezol treatment may change the absorption of the antiretroviral drug. Other possible interaction mechanisms are via CYP2C19. For some antiretroviral drugs, such as atazanavir and nelfinavir, decreased serum levels have been reported when given together with omeprazole. Following multiple doses of nelfinavir (1250 mg, bid) and Nexmezol (40 mg qd). AUC was decreased by 36% and 92%, Cmax by 37% and 89% and Cmin by 39% and 75% respectively for nelfinavir and M8. Following multiple doses of atazanavir (400 mg, qd) and Nexmezol (40 mg, qd, 2 hr before atazanavir), AUC was decreased by 94%, Cmax by 96%, and Cmin by 95%. Concomitant administration with Nexmezol and drugs such as atazanavir and nelfinavir is therefore not recommended. For other antiretroviral drugs, such as saquinavir, elevated serum levels have been reported with an increases in AUC by 82%, in Cmax by 75% and in Cmin by 106% following multiple dosing of saquinavir/ritonavir (1000/100 mg) bid for 15 days with Nexmezol 40 mg qd coadministered days 11 to 15. Therefore, clinical and laboratory monitoring for saquinavir toxicity is recommended during concurrent use with Nexmezol.

Dose reduction of saquinavir should be considered from the safety perspective for individual patients. There are also some antiretroviral drugs of which unchanged serum levels have been reported when given with Nexmezol.

Studies evaluating concomitant administration of Nexmezol and either naproxen (non-selective NSAID) or rofecoxib (COX-2 selective NSAID) did not identify any clinically relevant changes in the pharmacokinetic profiles of Nexmezol or these NSAIDs.

Nexmezol inhibits gastric acid secretion. Therefore, Nexmezol may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (eg, ketoconazole, iron salts and digoxin).

I am suffering from the severe erosive GERD feel like vomitting I was admitted at the hospital for gastroscop the results were sores that caused by stomach acid and something like stomach bug in the bile which causes acid problem I was given nexmezol tablets 40MG to be taken daily it's been 12days now but my chest is still aching but the oesofugus is now better than before thank you for the word of encouragement that I must continue to take the drug because the problem won't go in a day
