Pantoprazole Arrow Lab

Pantoprazole Arrow Lab Uses, Dosage, Side Effects, Food Interaction and all others data.

Pantoprazole Arrow Lab is chemically a novel substituted benzimidazole derivative, which suppresses the final step in gastric acid production by forming a covalent bond to two sites of H+/K+ATPase enzyme system at the secretory surface of the gastric parietal cell. This leads to inhibition of both basal and stimulated gastric effect that persists longer than 24 hours.

Pantoprazole Arrow Lab is quantitatively absorbed and its bioavailability does not change upon multiple dosing. Pantoprazole Arrow Lab is extensively metabolized in the liver. Almost 80% of an oral dose is excreted as metabolites in urine; the remainder is found in feces.

This drug acts to decrease gastric acid secretion, which reduces stomach acidity. Pantoprazole Arrow Lab administration leads to long-lasting inhibition of gastric acid secretion.

General Effects

Pantoprazole Arrow Lab has been shown to reduce acid reflux-related symptoms, heal inflammation of the esophagus, and improve patient quality of life more effectively than histamine-2 receptor antagonists (H2 blockers). This drug has an excellent safety profile and a low incidence of drug interactions. It can be used safely in various high-risk patient populations, including the elderly and those with renal failure or moderate hepatic dysfunction.

How Pantoprazole Arrow Lab works

Hydrochloric acid (HCl) secretion into the gastric lumen is a process regulated mainly by the H(+)/K(+)-ATPase of the proton pump, expressed in high quantities by the parietal cells of the stomach. ATPase is an enzyme on the parietal cell membrane that facilitates hydrogen and potassium exchange through the cell, which normally results in the extrusion of potassium and formation of HCl (gastric acid).

Proton pump inhibitors such as pantoprazole are substituted benzimidazole derivatives, weak bases, which accumulate in the acidic space of the parietal cell before being converted in the canaliculi (small canal) of the gastric parietal cell, an acidic environment, to active sulfenamide derivatives. This active form then makes disulfide bonds with important cysteines on the gastric acid pump, inhibiting its function. Specifically, pantoprazole binds to the sulfhydryl group of H+, K+-ATPase, which is an enzyme implicated in accelerating the final step in the acid secretion pathway. The enzyme is inactivated, inhibiting gastric acid secretion. The inhibition of gastric acid secretion is stronger with proton pump inhibitors such as pantoprazole and lasts longer than with the H(2) antagonists.

Side Effects

No potentially life-threatening effects have been reported with Pantoprazole Arrow Lab. Symptomatic adverse effects include headache and diarrhoea are two common reported adverse effects. Peripheral edema has been occasionally reported in female patients. Other side effects may include abdominal pain, dizziness, nausea, epigastric discomfort, flatulence, skin rash, pruritus etc.

Toxicity

Rat Oral LD 50 747 mg/kg

Tumorigenicity

Because of the chronic nature of GERD, there may be a potential for long-term administration of pantoprazole. In long-term rodent studies, pantoprazole was carcinogenic and its administration lead to rare types of gastrointestinal tumors. The relevance of these findings to tumor development in humans is unknown at this time.

Teratogenic Effects

This drug falls under pregnancy category B category. Reproduction studies have been performed in rats at oral doses up to 88 times the recommended human dose (RHD), as well as in rabbits at oral doses up to 16 times the RHD, and have shown no evidence of impaired fertility or harm to the fetus caused by pantoprazole. No adequate and well-controlled studies in pregnant women have been completed. Because animal reproduction studies are not always predictive of human response, this drug should only be used during pregnancy if clearly required.

Nursing Mothers

Pantoprazole Arrow Lab and its metabolites have been found to be excreted in the milk of rats. Pantoprazole Arrow Lab excretion in human milk has been found in a study performed with a single nursing mother after one 40 mg oral dose. The clinical relevance of this finding is not known, however, it is advisable to take note of this finding when considering pantoprazole use during nursing. Many drugs excreted in human breastmilk have a risk for serious adverse effects in nursing infants.

Precaution

Patients should be cautioned that Pantoprazole Arrow Lab tablet should not be split, crushed or chewed. The tablet should be swallowed whole, with or without food in the stomach. Concomitant administration of antacid does not affect the absorption of Pantoprazole Arrow Lab.

Interaction

There is no interaction with concomitantly administered antacids. No dosage adjustment is needed with combination use of the following drugs: Theophylline, Caffeine, Diazepam, Digoxin, Ethanol, Metoprolol, Nifedipine or Warfarin.

Food Interaction

  • Take with or without food. The absorption is unaffected by food.

Pantoprazole Arrow Lab Disease Interaction

Major: C. diffModerate: liver disease, bone fractures, hypomagnesemia

Volume of Distribution

The apparent volume of distribution of pantoprazole is approximately 11.0-23.6 L, distributing mainly in the extracellular fluid.

Elimination Route

Pantoprazole Arrow Lab is absorbed after oral administration as an enteric-coated tablet with maximum plasma concentrations attained within 2 – 3 hours and a bioavailability of 77% that does not change with multiple dosing . Following an oral dose of 40mg, the Cmax is approximately 2.5 μg/mL with a tmax of 2 to 3 hours. The AUC is approximately 5 μg.h/mL. There is no food effect on AUC (bioavailability) and Cmax.

Delayed-release tablets are prepared as enteric-coated tablets so that absorption of pantoprazole begins only after the tablet leaves the stomach.

Half Life

About 1 hour

Clearance

Adults: With intravenous administration of pantoprazole to extensive metabolizers, total clearance is 7.6-14.0 L/h. In a population pharmacokinetic analysis, the total clearance increased with increasing body weight in a non-linear fashion.

Children: clearance values in the children 1 to 5 years old with endoscopically proven GERD had a median value of 2.4 L/h.

Elimination Route

After a single oral or intravenous (IV) dose of 14C-labeled pantoprazole to healthy, normal metabolizing subjects, about 71% of the dose was excreted in the urine, with 18% excreted in the feces by biliary excretion. There was no kidney excretion of unchanged pantoprazole.

Pregnancy & Breastfeeding use

There are no adequate or well-controlled studies in pregnant women. Pantoprazole Arrow Lab should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

It is not known whether Pantoprazole Arrow Lab is excreted in human breast milk. Pantoprazole Arrow Lab should be used during lactation only if the potential benefit justifies the potential risk.

FAQ

What is Pantoprazole Arrow Lab used for?

Pantoprazole Arrow Lab is used to treat damage from gastroesophageal reflux disease (GERD), a condition in which backward flow of acid from the stomach causes heartburn and possible injury of the esophagus (the tube between the throat and stomach) in adults and children 5 years of age and older.

How does Pantoprazole Arrow Lab work?

Pantoprazole Arrow Lab is a type of medicine called a proton pump inhibitor (PPI). Proton pumps are tiny substances in the lining of the stomach that help it make acid to digest your food. Pantoprazole Arrow Lab prevents proton pumps from working properly. This reduces the amount of acid the stomach makes.
