Esomeprazole Pronunciation

Back to top

Description

Esomeprazole belongs to a class of medications know as Proton Pump Inhibitors (PPI's). PPI's, via the inhibition of H+/K+ ATPase enzyme pumps located in the gastric lumen, decrease the amount of gastric acid produced. Esomeprazole consists only of the active isomer (S-isomer), whereas its counterpart, Omeprazole contains the active and in-active isomers (R and S-isomers).[1]

Studies have shown that a decrease in the amount of gastric acid produced was beneficial for patients with Erosive Esophagitis, Symptomatic Gastroesophageal Reflux Disease (GERD), NSAID-Associated Gastric Ulcers, Heliocobacter pylori (H. pylori) infections, and Zollinger-Ellison Syndrome.[2] In patients with gastro-esophageal reflux disease (GERD), PPI_s have been shown to relieve patients of GERD symptoms. In other cases, such as patients with h. pylori infections or the development of ulcers with the use of NSAID_s, PPI_s have again proven to be efficacious in symptomatic and gastric damage relief.[3][4]

Mechanism of action

Esomeprazole, like other PPI's, is a prodrug that is activated in an acidic environment to it's active form (sulfenamide). The active form of the prodrug creates a covalent bond to H+/K+ ATPase pumps located on parietal cells in the gastric lumen. H+/K+ ATPase pumps are involved in the final step of the acid secretion pathway. This bond irreversibly inhibits the subsequent release of hydrogen ions. Inhibition of acid production is maintained until new H+/K+ ATPase pumps are regenerated (~18 hours).[3][1]

Time Required for Therapeutic Response

Pharmacokinetics

Absorption

Esomeprazole, intended for the oral route of administration, is formulated with an enteric coating to prevent rapid dissolution in the acidic environment of the gastric cavity. The different strengths of oral esomeprazole (20mg and 40mg) create the ranges seen in Cmax, Tmax and AUC. A single 40mg oral dose, taken without food, reaches its peak of 4.7 _mol/L (Cmax) within 1.5 hours (Tmax) with a bioavailability of 64%. The plasma concentration-time curve (AUC) for this single dose is 4.32 _mol*h/L. After multiple doses in fasting conditions, bioavailability increases to ~90% and the AUC increases to 11.2 _mol*h/L. The AUC decreases by 43-53% when a single dose is taken with food.[1][2] Due to the differences in isomeric composition, the AUC of Esomeprazole is 80% higher that that of Omeprazole. This is due to a decrease in the clearance and first-pass metabolism of the S-isomer.[1]

Intravenous forms of esomeprazole have a slightly different pharmacokinetic profile than the oral forms. The different strengths of IV esomeprazole (20mg and 40mg) create the ranges seen in Cmax and AUC. After the IV administration of a 40mg dose, given once daily for a total of 5 days, the AUC is 16.2 _mol*h/L with a peak concentration (Cmax) of 7.51 _mol/L.[6][7]

Distribution

Esomeprazole as an apparent volume of distribution of 16 L. Additionally, esomeprazole is approximately 97% protein bound. This applies to both the oral and intravenous forms.

Metabolism

Esomeprazole metabolism is mediated via the cytochrome P450 enzyme system (CYP450). The hydroxyl and desmethyl metabolites are formed by the CYP219 isoenzyme, while the sulphone metabolite is formed via the CYP3A4 enzyme. All metabolites formed are inactive.[2][1]

Excretion

The inactive metabolites of esomeprazole are mainly renally excreted (80%) with some fecal elimination (20%). A minimal amount of the active parent drug is excreted in the urine (1%). The elimination half life for both the oral and intravenous forms ranges from 1-1.5 hours, with a slightly longer half life with the oral forms of esomeprazole. Elimination is complete with no accumulation of drug.[8][2]

Special Population Pharmacokinetics

  • Renal Insufficiency

Due to the insignificant amount of renal elimination of active esomeprazole, there are expected to be no differences between healthy and renally impaired patients. No dosage adjustments are necessary.[2]

  • Hepatic Insufficiency

Patients with sever hepatic insufficiency (Child Pugh Class C) have been shown to have a 2-3 times higher AUC of esomeprazole than those with normal hepatic function. Those with mild-moderate hepatic insufficiency (Child Pugh Class A and B) reported no change in AUC.[2][9]

  • Hemodialysis

Unavailable

  • Geriatric

Both AUC and Cmax were higher in elderly patients, but this was without any significance. No dosage adjustments necessary.[2]

  • Pediatric

Any changes in patients ages 12-17 years old were similar to the changes seen in adult patients. No dosage changes are necessary.[2]

  • Gender

In female patients, AUC and Cmax were slightly higher than males, but without any significance. No dosage changes are necessary.[2]

Administration

  • Capsule[2]
    • Route: Oral
      • Method: Swallow capsule whole with a full glass of water or capsule can be opened and sprinkled/mixed with applesauce. Capsule should be taken once daily and is best if daily dose is taken one hour prior to a meal.
      • Special considerations: Applesauce must be at room temperature and should be administered right after mixing.
    • Route: Nasogastric Tube
      • Method: Open capsule and place granules into a catheter tipped syringe. Add 50ml of water to syringe, replace the plunger and shake contents of syringe for ~15 seconds. Attach syringe to nasogastric tube and inject syringe contents. Flush nasogastric tube with additional water. This should be done once daily.
      • Special considerations: Do not administer contents of syringe if granules are dissolved or disintergrated.
  • Powder for oral solution[2]
    • Route: Oral
      • Method: Mix contents of one packet with 15ml of water, stir and let sit for a couple of minutes to thicken. Drink suspension within 30 minutes of making. If any residual suspension remains, add more water and drink immediately.
    • Route: Nasogastric Tube
      • Method: In a catheter tipped syringe, add the contents of one packet to 15ml of water, shake and let sit for a couple of minutes to thicken. Shake the syringe and inject into nasogastric tube. Refill the syringe with 15ml of water and flush the NG- tube. Suspension must be administered within 30 minutes of making.
  • Powder for Intravenous Injection[6]
    • Route: Intravenous
      • Method: Reconstitute the powder with 5ml of 0.9% Sodium Chloride Injection, USP. Withdraw 5ml of solution and inject intravenously over no less then 3 minutes. This should be stored at room temperature and should be administered within 12 hours of making.

    • Route: Intravenous
      • Method: Reconstitute the powder with 5ml of 0.9% Sodium Chloride Injection, USP, Lactated Ringer_s Injection, USP or 5% Dextrose Injection, USP. The final admixture should then be diluted to a final volume of 50ml and can then be infused intravenously over 10-30 minutes. This should be stored at room temperature. If using 0.9% Sodium Chloride Injection or Lactated Ringer_s Injection for dilution, the admixture should be administered within 12 hours of making. If using 5% Dextrose Injection for dilution, the admixture should be administered within 6 hours.

Precautions

  • Gastric Malignancy[1]
  • Pregnancy: Although studies have been done in rats without any teratogenic outcomes, no studies have been performed in pregnant females. Caution is advised with the use of esomeprazole during pregnancy.[2]
  • Breast Feeding: Concentrations of esomeprazole have been found in breast milk. Caution should be used.[2]


Back to top

Pregnancy indications

  • Pregnancy Category: B
    • To date, there have been teratology studies done in rats without any shown harm to the fetus. This study, however, has not been performed in pregnant females but there have been sporadic reports of congenital abnormalities in infants born to mothers receiving esomeprazole therapy.[2]


Back to top

Breast-feeding indications

  • Secretion into breast milk: There are no studies of the secretion of esomeprazole into breast milk, although, concentrations of the drug have been found in breast milk. Because there have been no studies done in nursing females, caution is advised when using esomeprazole in nursing mothers. Discontinuation of the medication should be attempted if the nursing mother has indication to do so.[2]

Overdosage Measures

Dosages of around 510 mg/kg were observed to be toxic in rats. Signs of toxicity seen in rats included changes in respiratory frequency, tremor, reduced motor activity, ataxia, and intermittent clonic convulsions. In humans, doses greated than 120 times greater than the recommended dosages created toxicity such as confusion, drowsiness, blurred vision, tachcardia, nausea, flushing, headache and dry mouth. Toxicity was rarely seen when doses were kept within recommended therapeutic ranges. Overall, esomeprazole is well tolerated.[2]
