What is Nexprazin?

Nexprazin strontium is used to treat conditions where there is too much acid in the stomach. It is used to treat duodenal and gastric ulcers, erosive esophagitis, gastroesophageal reflux disease (GERD), and the Zollinger-Ellison syndrome. Nexprazin is also used with antibiotics (eg, amoxicillin, clarithromycin) to treat ulcers that are caused by the H. pylori bacteria. Nexprazin strontium is also used to prevent stomach ulcers and stomach irritation in patients taking pain and arthritis drugs called NSAIDs, such as aspirin or ibuprofen, for long periods of time.

Nexprazin strontium is a proton pump inhibitor (PPI). It works by decreasing the amount of acid that is produced by the stomach.

Nexprazin strontium is available only with your doctor’s prescription.

Nexprazin 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.

Treatment of Gastroesophageal Reflux Disease (GERD)

Healing of Erosive Esophagitis

Nexprazin Magnesium Delayed-Release Capsules are indicated for the short-term treatment (4 to 8 weeks) in the healing and symptomatic resolution of diagnostically confirmed erosive esophagitis. For those patients who have not healed after 4 to 8 weeks of treatment, an additional 4 to 8 week course of Nexprazin Magnesium Delayed-Release Capsules may be considered.

Maintenance of Healing of Erosive Esophagitis

Nexprazin Magnesium Delayed-Release Capsules are indicated to maintain symptom resolution and healing of erosive esophagitis. Controlled studies do not extend beyond 6 months.

Symptomatic Gastroesophageal Reflux Disease

Nexprazin Magnesium Delayed-Release Capsules are indicated for short-term treatment (4 to 8 weeks) of heartburn and other symptoms associated with GERD in adults and children 1 year or older.

Risk Reduction of NSAID-Associated Gastric Ulcer

Nexprazin Magnesium Delayed-Release Capsules are indicated for the reduction in the occurrence of gastric ulcers associated with continuous NSAID therapy in patients at risk for developing gastric ulcers. Patients are considered to be at risk due to their age (≥ 60) and/or documented history of gastric ulcers. Controlled studies do not extend beyond 6 months.

H. pylori Eradication to Reduce the Risk of Duodenal Ulcer Recurrence

Triple Therapy (Nexprazin Magnesium Delayed-Release Capsules plus amoxicillin and clarithromycin): Nexprazin Magnesium Delayed-Release Capsules, in combination with amoxicillin and clarithromycin, is indicated for the treatment of patients with H. pylori infection and duodenal ulcer disease (active or history of within the past 5 years) to eradicate H. pylori. Eradication of H. pylori has been shown to reduce the risk of duodenal ulcer recurrence.

In patients who fail therapy, susceptibility testing should be done. If resistance to clarithromycin is demonstrated or susceptibility testing is not possible, alternative antimicrobial therapy should be instituted.

Pathological Hypersecretory Conditions Including Zollinger-Ellison Syndrome

Nexprazin Magnesium Delayed-Release Capsules are indicated for the long-term treatment of pathological hypersecretory conditions, including Zollinger-Ellison Syndrome.

How should I use Nexprazin?

Use Nexprazin 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 Nexprazin suspension.

Uses of Nexprazin 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. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Nexprazin interactions

See also:
What other drugs will affect Nexprazin?

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

In vitro and in vivo studies have shown that Nexprazin 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 Nexprazin 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 Nexprazin 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.

Nexprazin may potentially interfere with CYP2C19, the major Nexprazin metabolizing enzyme. Coadministration of Nexprazin 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 Nexprazin and a combined inhibitor of CYP2C19 and CYP3A4, such as voriconazole, may result in more than doubling of the Nexprazin exposure. Dose adjustment of Nexprazin is not normally required for the recommended doses. However, in patients who may require higher doses, dose adjustment may be considered.

Nexprazin acts as an inhibitor of CYP2C19. Nexprazin 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 Nexprazin 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 Nexprazin.

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.

Nexprazin 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 Nexprazin 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 Nexprazin (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 Nexprazin (40 mg, qd, 2 hr before atazanavir), AUC was decreased by 94%, Cmax by 96%, and Cmin by 95%. Concomitant administration with Nexprazin 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 Nexprazin 40 mg qd coadministered days 11 to 15. Therefore, clinical and laboratory monitoring for saquinavir toxicity is recommended during concurrent use with Nexprazin.

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 Nexprazin.

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

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

Clinical Trials Experience With

Intravenous Nexprazin

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Adults

The safety of intravenous Nexprazin is based on results from clinical trials conducted in four different populations including patients having symptomatic GERD with or without a history of erosive esophagitis (n=199), patients with erosive esophagitis (n=160), healthy subjects (n=204) and patients with bleeding gastric or duodenal ulcers (n=375).

Symptomatic GERD and Erosive Esophagitis Trials

The data described below reflect exposure to Nexprazin I.V. for Injection in 359 patients. Nexprazin I.V. for Injection was studied only in actively-controlled trials. The population was 18 to 77 years of age; 45% Male, 52% Caucasian, 17% Black, 3% Asian, 28% Other, and had either erosive reflux esophagitis (44%) or GERD (56%). Most patients received doses of either 20 or 40 mg either as an infusion or an injection. Adverse reactions occurring in ≥ 1% of patients treated with intravenous Nexprazin (n=359) in clinical trials are listed below:

Table 2 : Adverse reactions occurring at an incidence ≥ 1% in the Nexprazin I.V. group

Adverse Reactions % of patients Nexprazin

Intravenous (n=359)

Headache 10.9
Flatulence 10.3
Nausea 6.4
Abdominal pain 5.8
Diarrhea 3.9
Mouth dry 3.9
Dizziness/vertigo 2.8
Constipation 2.5
Injection site reaction 1.7
Pruritus 1.1

Intravenous treatment with Nexprazin 20 and 40 mg administered as an injection or as an infusion was found to have a safety profile similar to that of oral administration of Nexprazin.

Pediatric

A randomized, open-label, multi-national study to evaluate the pharmacokinetics of repeated intravenous doses of once daily Nexprazin in pediatric patients 1 month to 17 years old, inclusive was performed. The safety results are consistent with the known safety profile of Nexprazin and no unexpected safety signals were identified.

Risk Reduction of Rebleeding of Gastric or Duodenal Ulcers in Adults

The data described below reflect exposure to Nexprazin I.V. for Injection in 375 patients. Nexprazin I.V. for Injection was studied in a placebo-controlled trial. Patients were randomized to receive Nexprazin I.V. for Injection (n=375) or placebo (n=389). The population was 18 to 98 years old; 68% Male, 87% Caucasian, 1% Black, 7% Asian, 4% other, who presented with endoscopically confirmed gastric or duodenal ulcer bleeding. Following endoscopic hemostasis, patients received either 80 mg Nexprazin as an intravenous infusion over 30 minutes followed by a continuous infusion of 8 mg per hour or placebo for a total treatment duration of 72 hours. After the initial 72-hour period, all patients received oral proton pump inhibitor (PPI) for 27 days.

#Injection site reactions included erythema, swelling, inflammation, pruritus, phlebitis, thrombophlebitis and superficial phlebitis.

With the exception of injection site reactions described above, intravenous treatment with Nexprazin administered as an injection or as an infusion was found to have a safety profile similar to that of oral administration of Nexprazin.

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of Nexprazin. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Postmarketing Reports - There have been spontaneous reports of adverse events with postmarketing use of Nexprazin. These reports occurred rarely and are listed below by body system:

Blood And Lymphatic System Disorders: agranulocytosis, pancytopenia;

Eye Disorders: blurred vision;

Gastrointestinal Disorders: pancreatitis; stomatitis; microscopic colitis;

Hepatobiliary Disorders: hepatic failure, hepatitis with or without jaundice;

Immune System Disorders: anaphylactic reaction/shock;

Infections and Infestations: GI candidiasis;

Metabolism and nutritional disorders: hypomagnesemia;

Musculoskeletal And Connective Tissue Disorders: muscular weakness, myalgia, bone fracture;

Nervous System Disorders: hepatic encephalopathy, taste disturbance;

Psychiatric Disorders: aggression, agitation, depression, hallucination;

Renal and Urinary Disorders: interstitial nephritis;

Reproductive System and Breast Disorders: gynecomastia;

Respiratory, Thoracic and Mediastinal Disorders: bronchospasm;

Skin and Subcutaneous Tissue Disorders: alopecia, erythema multiforme, hyperhidrosis, photosensitivity, Stevens-Johnson syndrome, toxic epidermal necrolysis (TEN, some fatal).

Other adverse events not observed with Nexprazin, but occurring with omeprazole can be found in the omeprazole package insert, ADVERSE REACTIONS section.

Nexprazin contraindications

See also:
What is the most important information I should know about Nexprazin?

Nexprazin is rapidly absorbed after oral doses, with peak plasma levels occurring after about 1-2 hrs. It is acid labile and an enteric-coated formulation has been developed. Bioavailability of Nexprazin increases with both dose and repeated administration to about 68% and 89% for doses of 20 mg and 40 mg, respectively. Food delays and decreases the absorption of Nexprazin, but this does not significantly change its effect of intragastric acidity. Nexprazin is about 97% bound to plasma proteins. It is extensively metabolized in the liver by the cytochrome P450 (CYP450) isoenzyme CYP2C19 to hydroxy and desmethyl metabolites, which have no effect on gastric acid section. The remainder is metabolized by the CYP450 isoenzyme CYP3A4 to Nexprazin sulfone. With repeated dosage, there is a decrease in first-pass metabolism and systemic clearance, probably caused by an inhibition of the CYP2C19 isoenzyme. However, there is no accumulation during once daily use. The plasma elimination half-life (t½) is about 1.3 hrs. Almost 80% of an oral dose is eliminated as metabolites in the urine, the remainder in the feces.
