Dexilant capsules 30mg #14
Dexilant Pharmachologic Effect:
Mode of action - inhibiting the proton pump, antiulcer.
Dexilant Pharmacodynamics:
Dekslansoprazol is a proton pump inhibitor, suppresses gastric acid secretion by inhibiting H + / K + -ATPase in the parietal cells of the stomach. Blocks the final stage of hydrochloric acid secretion.
Dexilant® capsule formulation contains two types of granules, enteric-coated, which release capsules after the dissolution of the active substance in the stomach as a function of pH in different areas of the small intestine. This helps to prolong the effect of a combination dekslansoprazola and reduces gastric acid secretion for an extended time.
Dexilant Pharmacokinetics:
Suction
Dekslansoprazol well absorbed when taken orally. Its bioavailability is 76% or more. Two part Dexilant® drug absorption causes a pH-dependent two phases. The first peak of the active substance concentration occurs in the range of 1 to 2 hours after oral administration (1st phase release of active ingredient) and the second - in the range of 4 to 5 hours (2nd phase the release of active substance), respectively. After 5 days of dekslansoprazol in doses of 30 and 60 mg in a plasma Cmax of 658 and 1397 ng / ml, respectively.
AUC is 3275 ng-hr / mL and 6529 ng · h / mL after 5 days of dekslansoprazol in doses of 30 and 60 mg, respectively.
Dexilant Distribution:
Dekslansoprazola Binding to plasma proteins is 96,1-98,8%.
Dexilant Metabolism:
Dekslansoprazol extensively metabolized in the liver to inactive metabolites as a result of oxidation, reduction and the subsequent formation of sulfate, glucuronide and glutathione compounds.
The oxidation is carried out by the enzyme cytochrome P450, which participates in the process of hydroxylation (preferably isoenzyme CYP2C19), and in the oxidation process (isoenzyme CYP3A4). CYP2C19 isozyme hepatic isoenzyme is polymorphic, existing in three fractions exhibiting different properties in the metabolism of substrates (fast, moderate and slow metabolizers). In the case of medium and strong metabolizers by isoenzyme CYP2C19, a major metabolite in plasma is 5 and glucuronic gidroksidekslansoprazol compound. In poor metabolizers by isoenzyme CYP2C19 - dekslansoprazola sulfone.
Dexilant Breeding:
T1 / 2 of the drug - 1-2 hours.
Clearance after 5 days of dekslansoprazola is 11.4 and 11.6 l / h for dosing of 30 and 60 mg, respectively.
The drug is eliminated via the kidneys (approximately 51%) and 48% is excreted through the intestines.
Since the drug is extensively metabolized in the liver, when applying dekslansoprazola in patients with impaired renal function dose reduction is required. As in patients with normal renal function is not expected to alter the pharmacokinetics.

Interaction:
Dekslansoprazol can be assigned without the risk of drug interactions in patients receiving clopidogrel. In the case of co-administration of clopidogrel dose adjustments required. It is also noted the absence of clinically significant drug interactions with phenytoin, theophylline and diazepam.
Simultaneous application dekslansoprazola can affect the absorption of drugs, bioavailability depends on the pH of the gastric environment (e.g. ampicillin complex esters, digoxin, iron salts, ketoconazole, erlotinib).
Simultaneous treatment with tacrolimus may increase tacrolimus concentrations in blood plasma, particularly after transplantation in patients who are slow metabolizers moderate or isoenzyme by CYP2C19.
When concomitantly with fluvoxamine is likely to increase systemic exposure dekslansoprazol.
Simultaneous reception dekslansoprazola and methotrexate can lead to higher and higher concentrations of methotrexate conservation and / or its metabolite in the blood serum. If you want to receive high-dose methotrexate is recommended to cancel the temporary reception dekslansoprazola.
Dosing and Administration:
Inside, a capsule taken as a whole, regardless of the meal.
You can also open the capsule, pour out of it in a tablespoon of granules and mix them with applesauce; then immediately, without chewing, swallowing.
Treatment of erosive esophagitis of any severity. The recommended dose is 60 mg 1 time per day. The course of treatment - 8 weeks.
Maintenance therapy after treatment of erosive esophagitis and heartburn relief manifestations. The recommended dose is 30 mg 1 time per day. In the study treatment was up to 6 months.
Patients with erosive esophagitis moderate and severe recommended dose is 60 mg 1 time per day. In the study treatment was up to 6 months.
Symptomatic treatment of gastroesophageal reflux disease (GERD, including NERD - non-erosive reflux disease). The recommended dose is 30 mg 1 time per day. The course of treatment - 4 weeks.
In patients with impaired function of the liver moderate (Class B for Child-Pugh) daily dose should not exceed 30 mg dekslansoprazola. Clinical data on the admission of the drug in patients with severe impairment of patients (class C Child-Pugh) are absent.
Correction of the dose in elderly patients, patients with impaired renal function and in violation of mild liver function (class A on Child-Pugh) is not required.
Overdose:
Posts on significant cases of overdose Dexilant® was no preparation. Multiple receiving doses of 120 mg and a single dose of 300 mg did not cause severe side effects. There has been a side effect of raising blood pressure above 140/90 mm Hg Dexilant® when taking the drug, 60 mg 2 times a day.
However, in case of overdose only when clinical manifestations symptomatic therapy.
Dekslansoprazol not output through hemodialysis.
Special instructions:
Before treatment dekslansoprazolom to exclude the possibility of malignant neoplasms of the gastrointestinal tract, since the drug may mask the symptoms and delay the correct diagnosis.
If symptoms persist despite adequate treatment, it should be further examination.
When receiving proton pump inhibitors, which include dekslansoprazol, increased risk of gastrointestinal infections, diarrheal pathogens that are bacteria of the genus Clostridium difficile, especially in hospitalized patients. It must be taken into account if the patient's condition does not improve the treatment of diarrhea. Patients in this case it is recommended to take the lowest effective dose dekslansoprazola at least the duration of treatment.
In patients receiving high doses or prolonged therapy, proton pump inhibitors (PPIs) for a year or more increases the risk of osteoporotic hip fractures, wrist and spine. Patients at risk for osteoporotic fractures should adhere to the recommended dosage (see. "Dosage and administration").
In rare cases, patients had symptomatic and asymptomatic hypomagnesemia while taking PPI drugs for at least 3 months, and in most cases - for admission to the course of the year. Symptoms are hypomagnesemia tetany, arrhythmias and seizures. Treatment - magnesium replenishment and cancel receiving PPI medication. In patients who need long-term treatment or concurrently taking drugs PPIs with digoxin or other drugs that can cause hypomagnesemia (eg diuretics) should be monitored in serum magnesium concentration before and during treatment.
Effects on ability to drive vehicles / machinery. Because of the likelihood of dizziness and blurred vision should refrain from driving and other mechanisms that require attention.
