Omeprazole
Omeprazole (Losec , Prilosec)
Omeprazole
(oh- MEH-prah-zohl)
Pregnancy Category: C Losec Prilosec (Rx)

Classification: Agent to suppress gastric acid secretion

Action/Kinetics: Thought to be a gastric pump inhibitor in that it blocks the final step of acid production by inhibiting the H +-K + ATPase system at the secretory surface of the gastric parietal cell. Both basal and stimulated acid secretions are inhibited. Serum gastrin levels are increased during the first 1 or 2 weeks of therapy and are maintained at such levels during the course of therapy. Because omeprazole is acid-labile, the product contains an enteric-coated granule formulation; however, absorption is rapid. Peak plasma levels: 0.5-3.5 hr. Onset: Within 1 hr. t 1/2: 0.5-1 hr. Duration: Up to 72 hr (due to prolonged binding of the drug to the parietal H +-K +; ATPase enzyme). Significantly bound (95%) to plasma protein. Metabolized in the liver and inactive metabolites are excreted through the urine. Consider dosage adjustment in Asians.

Uses: Short-term (4 to 8-week) treatment of active duodenal ulcer, active benign gastric ulcer, erosive esophagitis (all grades), and heartburn and other symptoms associated with GERD. In combination with clarithromycin for eradication of Helicobacter pylori and treatment of active duodenal ulcer. In combination with clarithromycin and amoxicillin for eradication of H. pylori and treatment of active duodenal ulcer. Long-term maintenance therapy for healed erosive esophagitis. Long-term treatment of pathologic hypersecretory conditions such as Zollinger-Ellison syndrome, multiple endocrine adenomas, and systemic mastocytosis. Investigational: Posterior laryngitis, enhanced efficacy of pancreatin for treating steatorrhea in cystic fibrosis.

Contraindications: Lactation. Use as maintenance therapy for duodenal ulcer disease.

Special Concerns: Bioavailability may be increased in geriatric clients. Use with caution during lactation. Symptomatic effects with omeprazole do not preclude gastric malignancy. Safety and effectiveness have not been determined in children.

Laboratory Test Alterations: AST, ALT, gamma-glutamyl transpeptidase, alkaline phosphatase, bilirubin, serum creatinine. Glycosuria, hyponatremia, hypoglycemia.

Overdose Management: Symptoms: Confusion, drowsiness, blurred vision, tachycardia, nausea, diaphoresis, flushing, headache, dry mouth. Treatment: Symptomatic and supportive. Omeprazole is not readily dialyzable.

Drug Interactions: Ampicillin (esters) / Possible absorption of ampicillin esters R/T stomach pH Clarithromycin / Possible plasma levels of both drugs Diazepam / Diazepam plasma levels R/T rate of liver metabolism Iron salts / Possible absorption of iron salts R/T stomach pH Ketoconazole / Possible ketoconazole absorption R/T stomach pH Phenytoin / Plasma phenytoin levels R/T rate of liver metabolism Sucralfate / Omeprazole absorption; take 30 min before sucralfate Warfarin / Prolonged rate of warfarin elimination R/T rate of liver metabolism

Have been using this drug for 3 months and am symptom-free. Only question I have is about prolonged use. Is it causing my chest fluttering?

The hard part was learning the timing. I have been taking Omeprazole Oral and have found it to be most effective if taken exactly 30 minutes before I eat. When I started it I took the pill at night on an empty stomach, which didn’t bring relief. Then I took it in the morning after eating breakfast and was still not pleased with the results. I am hoping to see my esophagus heal with proper timing of the pills and watching what I eat and how much. Being so careful and detailed now may help me avoid getting back into this situation again.

I am completely disappointed in this generic medication. My insurance company will only pay for the generic form, but the generic version does nothing to get rid of the terrible burning symptoms of my condition.
