   No boxed warning. Warnings and precautions 5.1 to 5.13: symptomatic response does not preclude gastric malignancy; acute tubulointerstitial nephritis may occur at any point during therapy, sometimes without extra-renal signs, and requires discontinuation; Clostridium difficile-associated diarrhoea, especially in hospitalised patients; osteoporosis-related fractures of hip, wrist or spine with high-dose (multiple daily doses) and long-term (a year or longer) therapy; severe cutaneous adverse reactions including Stevens-Johnson syndrome, toxic epidermal necrolysis, DRESS and AGEP; cutaneous and systemic lupus erythematosus, new or exacerbated, within weeks to years of continuous therapy, most patients improving 4 to 12 weeks after stopping; avoid clopidogrel; daily acid suppression longer than about 3 years may cause cyanocobalamin malabsorption; hypomagnesaemia reported rarely after at least 3 months and in most cases after a year, with tetany, arrhythmias and seizures, possibly causing hypocalcaemia or hypokalaemia, in most patients requiring magnesium replacement and discontinuation; chromogranin A rises and gives false-positive neuroendocrine tumour tests (stop at least 14 days before testing); high-dose methotrexate toxicity; fundic gland polyps with risk rising with use beyond one year. Contraindicated with rilpivirine; hypersensitivity may include anaphylaxis, angioedema, bronchospasm and acute tubulointerstitial nephritis. Warfarin co-use raised INR, which may lead to abnormal bleeding and death. Postmarketing reports include pancreatitis, hepatic failure, agranulocytosis and SJS/TEN (each some fatal), microscopic colitis, hyponatraemia, hypoglycaemia and optic neuropathies. Serum gastrin rose in the first 1 to 2 weeks, median 1.3- to 3.6-fold with omeprazole 20 mg against 1.1- to 1.8-fold with H2-receptor antagonists, and returned to baseline 1 to 2 weeks after stopping; gastrin causes ECL-cell hyperplasia and chromogranin A rise. In biopsies from more than 3000 patients in long-term trials, ECL-cell hyperplasia increased with time without carcinoid, dysplasia or neoplasia, but the studies were of insufficient duration and size to rule out an influence on premalignant or malignant conditions. Omeprazole for 14 days raised intragastric viable bacteria, resolving within 3 days of stopping. In two 24-month rat studies at 1.7 to 140.8 mg/kg/day (about 0.4 to 34 times a 40 mg human dose by body surface area), omeprazole produced dose-related gastric ECL-cell carcinoids, more in females; ECL-cell hyperplasia occurred in all treated groups. Esomeprazole reduced femur weight and length in juvenile rats. Erosive oesophagitis healing at 8 weeks: 74% with 20 mg (n = 83), 75% with 40 mg (n = 87), 14% with placebo (n = 43); endoscopic remission at 6 months: 70% with 20 mg daily (n = 138) against 11% with placebo (n = 131). Efficacy beyond 8 weeks for erosive oesophagitis is not established; controlled maintenance studies do not extend beyond 12 months.

Healing trials: endoscopic healing OR 5.22 (99% CI 4.00 to 6.80) for PPIs and 3.80 (3.44 to 4.20) for H2-receptor antagonists. Reductions in symptomatic ulcers and bleeds were smaller in trials with secure allocation concealment; the authors consider overestimation from small-study bias possible. H. pylori and NSAIDs are the most frequent causes of peptic ulcer; NSAID risk probably follows inhibited mucosal prostaglandin production.

    Review of 38 Adverse Event Reporting System cases and 23 published cases, at least 8 of them overlapping. Prescription PPIs may cause hypomagnesaemia when taken for prolonged periods, in most cases longer than one year; in about one quarter of cases magnesium supplementation alone was insufficient and the PPI was stopped. After stopping, magnesium normalised in a median of one week; after restarting, hypomagnesaemia recurred in a median of two weeks. Serious events included tetany, seizures, arrhythmias and hypocalcaemia with normal parathyroid hormone. The mechanism is unknown, possibly altered intestinal absorption. Serum magnesium should be considered before and periodically during prolonged treatment, especially with digoxin, loop or thiazide diuretics or other drugs causing hypomagnesaemia. Patients should not stop a prescription PPI without talking to their healthcare professional. Lists Dexilant (dexlansoprazole) among prescription PPIs.

    Observational studies suggest a modest increase in the risk of hip, wrist or spine fracture, especially with high doses and use longer than 1 year, observed mainly in elderly patients; other risk factors may contribute. Two meta-analyses of pharmacoepidemiological studies suggest a 10% to 40% increase above baseline; the primary studies varied in adjustment for other fracture risk factors and for calcium or vitamin D use. Patients at risk of osteoporosis should be treated according to guidelines with adequate vitamin D and calcium. Over-the-counter PPIs should not be used for more than 4 weeks without consulting a doctor.

    Review of seven published epidemiological studies using claims databases: six reported an increased risk of hip, wrist or spine fracture with PPI use, greatest with high doses or use for one year or more, mainly in people aged 50 years or older. The databases lacked data on family history of osteoporosis, smoking, weight, height, alcohol, calcium and vitamin D intake, indication and falls. Randomised trials, generally six months long, found no increase in fractures. It is not clear whether PPI use causes the increased risk. The 2011 update judged fracture risk with short-term, low-dose use unlikely.

    Non-prescription pantoprazole 20 mg once daily for short-term treatment of reflux symptoms in adults; treatment should not exceed 4 weeks without consulting a doctor. Section 4.4: reduced acidity raises gastric bacterial counts and slightly increases the risk of Salmonella, Campylobacter and Clostridium difficile infection; severe cutaneous adverse reactions (erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, DRESS), which can be life-threatening or fatal, frequency not known; very infrequent subacute cutaneous lupus erythematosus, with risk of recurrence on another PPI; chromogranin A rise interferes with neuroendocrine tumour investigations. Risks of long-term use: reduced vitamin B12 absorption; hip, wrist and spine fracture, predominantly in the elderly, with observational studies suggesting a 10% to 40% increase in overall fracture risk, some of it possibly due to other risk factors; severe hypomagnesaemia reported rarely after at least 3 months and in most cases a year, with fatigue, tetany, delirium, convulsions, dizziness and ventricular arrhythmia, possibly leading to hypocalcaemia and hypokalaemia, in most patients improving after magnesium replacement and discontinuation. Section 4.8: fundic gland polyps (benign) common; agranulocytosis rare; tubulointerstitial nephritis with possible progression to renal failure, hepatocellular failure, microscopic colitis, hyponatraemia and hallucination frequency not known. Section 5.1: fasting gastrin doubles in most cases during long-term treatment, with a mild to moderate increase in ECL cells in a minority; carcinoid precursors or gastric carcinoids, as seen in animals, have not been observed in humans. Section 5.3: 2-year rat studies produced gastric neuroendocrine neoplasms, attributed to massively elevated serum gastrin; liver tumours in rats and female mice and thyroid neoplastic changes in rats at 200 mg/kg; reduced bone growth in rat offspring at exposures about twice human clinical exposure.

    Very few cases of subacute cutaneous lupus erythematosus (SCLE) have been reported considering the extensive use of PPIs, but evidence from the literature and from Yellow Card and other regulatory reports supports a causal association. A Swedish register-based case-control study estimated an SCLE risk almost 3 times that of the general population with PPI use (OR 2.9, 95% CI 2.0 to 4.0); a Danish dermatology unit identified 19 PPI-associated cases over 19 years (3 definite, 14 probable). Across literature and licence-holder cases, 36 resolved on stopping the PPI and 4 recurred with a different PPI. Drug-induced SCLE can occur weeks, months or years after exposure; in most cases symptoms resolve on withdrawal, and a patient who develops SCLE with one PPI may react to another.

Among PPI users, quarters with a filled PPI prescription had higher adjusted rates than quarters without of community-acquired pneumonia (111 against 68 per 10,000), chest pain (597 against 336) and urinary tract infection (186 against 151), all p<0.001; PPI users also had higher rates than non-users in quarters without a prescription (pneumonia 68 against 61 per 10,000). Associations with conditions without a known pathophysiological link indicate that the association with pneumonia may be confounded.

    PPIs were consistently associated with increased gastric cancer risk: 20 of 21 meta-analyses reported pooled relative risks between 1.3 and 2.9. Available trials were underpowered. Reverse causation or protopathic bias, residual confounding by indication, lag time and disentangling Helicobacter pylori and its eradication were the largest methodological challenges. Age- and sex-specific data were insufficient, and no study addressed PPIs in young populations; the authors hypothesise that exposure in pregnancy and early life may be particularly harmful. Swedish gastric cancer incidence fell overall from 1970 to 2022 but rose in men younger than 40 years from the early 2000s.

    With a 1-year lag, PPI use was associated with gastric cancer in the case-control study (adjusted OR 1.49, 95% CI 1.24 to 1.80) and not significantly in UK Biobank (adjusted HR 1.28, 0.86 to 1.90); with a 2-year lag, adjusted OR 1.13 (0.91 to 1.40) and HR 1.15 (0.73 to 1.82). With a 3-year lag, OR 1.03 (0.80 to 1.33). The association did not follow exposure response, the shortest use carrying the highest risk, and weakened with longer lags, which the authors interpret as suggesting reverse causation; they observed little consistent evidence of increased risk.

ATP4B (P51164): beta subunit required for assembly and membrane targeting and stabilising the E2 conformation. ATP12A (P54707): the non-gastric H+/K+-ATPase of apical epithelial membranes, involved in K+ absorption in kidney and colon and in airway mucus acidification; expressed in airway epithelium, skin, kidney and prostate; inhibited by ouabain and SCH-28080. GAST (P01350): gastrin stimulates gastric HCl secretion and pancreatic enzyme secretion. CCKBR (P32239): receptor for gastrin and cholecystokinin, expressed in brain, pancreas and stomach (high in fundic mucosa); also reduces intestinal SGLT1 and GLUT2 expression (by similarity). HDC (P19113): histidine decarboxylase forms histamine from histidine. CHGA (P10645): chromogranin A, secreted from neuroendocrine vesicles. CBLIF (P27352): intrinsic factor of the gastric mucosa, required for ileal cobalamin absorption; deficiency causes megaloblastic anaemia. TRPM6 (Q9BX84): channel crucial for Mg2+ homeostasis and active Mg2+ absorption in gut and kidney, highly expressed in kidney and colon; loss of function causes hypomagnesaemia with secondary hypocalcaemia. DDAH1 (O94760): hydrolyses asymmetric dimethylarginine (ADMA) and monomethylarginine, inhibitors of nitric oxide synthase, to citrulline; detected in brain, liver, kidney and pancreas. TCIRG1 (Q13488): a3 subunit of the V-type H+-ATPase that acidifies the extracellular space in some cell types, highly expressed in osteoclastomas; loss causes autosomal recessive osteopetrosis.

    Narrative review by researchers of gastrin biology arguing that experimental and mechanistic evidence supporting causal adverse effects may have been underestimated by epidemiologists and meta-analysts. Rats given omeprazole or the H2-receptor antagonists loxtidine or ranitidine at doses causing prolonged acid inhibition and hypergastrinaemia developed corpus ECL-cell tumours; hypergastrinaemia induced by partial corpectomy or ciprofibrate, without hypoacidity, also produced them, and the gastrin-receptor antagonist YF476 inhibited tumour formation in Mastomys natalensis and may prevent it in female cotton rats. ECL-cell carcinoids in PPI users are, the authors argue, probably under-reported and may regress after stopping; patients homozygous for an inactivating ATP4A mutation develop ECL-cell carcinoids and adenocarcinoma in the third to fourth decade, suggesting that the exposure needed for neoplasia may be several decades. CYP2C19 poor metabolisers have higher intragastric pH and, the authors suggest without direct evidence, may be more prone to adverse effects; mice can hardly be dosed to sustained hypoacidity, which limits negative mouse studies.

    PPI users had lower abundance of gut commensals and lower microbial diversity, with increased oral and upper gastrointestinal commensals, in particular Streptococcaceae. Associations replicated in an interventional study and in monozygotic twin pairs discordant for PPI use. The authors propose that removal of the low-pH barrier lets upper gastrointestinal bacteria reach the lower gut.

    Narrative review. Parietal-cell HCl keeps luminal pH below 2 and promotes absorption of phosphate, calcium and iron. Histamine from enterochromaffin-like cells acts through Gs-coupled H2 receptors, adenylate cyclase, cAMP and protein kinase A, the rate-limiting trigger of secretion; acetylcholine acts through M3 and gastrin through CCK2 (CCKBR) receptors, both Gq-coupled with Ca2+ release; in humans gastrin acts mainly by releasing histamine from ECL cells. Somatostatin inhibits parietal, ECL and G cells; loss of acid secretion raises gastrin; CCK2R-deficient mice have fewer parietal and ECL cells. The H+/K+-ATPase, a P2-type ATPase of alpha (ATP4A) and beta (ATP4B) subunits in tubulovesicles that fuse with the canaliculus on stimulation, exchanges cytoplasmic H+ for luminal K+ supplied by KCNQ1-KCNE2. All PPIs bind Cys813 of the alpha subunit, arresting the pump in E2; Cys822, bound by pantoprazole, lies in the membrane domain and resists reducing agents. COX-1 (PTGS1) products PGE2 and PGI2 inhibit acid secretion and protect the mucosa; NSAIDs augment acid secretion.

    Narrative review. PPIs are acid-activated prodrugs: a pyridine with pKa about 4 (3.8 to 4.9) concentrates them about 1000-fold in the secretory canaliculus at pH about 1; a second protonation (benzimidazole pKa about 1) yields a sulfenic acid or tetracyclic sulfenamide that forms disulfides with luminal cysteines: Cys813 and Cys892 for omeprazole, Cys813 and Cys321 for lansoprazole, Cys813 and Cys822 for pantoprazole; pantoprazole binding resists glutathione reduction. The pump exchanges 2 H+ and 2 K+ per ATP at pH 6.1 and 1 of each below luminal pH 3.0. Plasma half-life about 1 hour; acid inhibition lasts about 48 hours; steady state after 2 to 3 days; once-daily dosing 30 to 60 minutes before breakfast inhibits about 66% of maximal acid output, twice-daily about 80%. Pump half-life about 54 hours in rats; half-time of recovery of acid secretion in humans about 24 hours after omeprazole and 46 hours after pantoprazole. Bioavailability 77% for pantoprazole, 80% to 90% for lansoprazole, 89% for esomeprazole; hepatic metabolism mainly by CYP2C19 and CYP3A4; hepatic impairment raises AUC sevenfold. CYP2C19 poor metabolisers are 3% of Caucasians and 15% to 20% of Asians; their AUC is about 7.5-fold that of homozygous extensive metabolisers for omeprazole and 4.5-fold for lansoprazole, with median intragastric pH about 6 against 3 to 4. Oesophagitis heals well when intragastric pH exceeds 4 for 16 hours a day, peptic ulcer when it exceeds 3 for 16 hours. Esomeprazole is the S-enantiomer of omeprazole.

    Clopidogrel is a prodrug absorbed in the intestine and activated in the liver by two sequential oxidative steps, the first forming 2-oxo-clopidogrel and the second the active metabolite. CYP1A2, CYP2B6 and CYP2C19 form 2-oxo-clopidogrel from clopidogrel in liver microsomes; with 2-oxo-clopidogrel as substrate, CYP3A4, CYP2C9, CYP2C19 and CYP2B6 produce the active metabolite. Kazui and colleagues concluded that CYP2C19 contributes substantially to both steps and CYP3A4 to the second. In a competing reaction about 85% of the drug is hydrolysed by esterases to an inactive carboxylic acid. The thiol group of the active metabolite binds a free cysteine of the P2Y12 receptor (P2RY12) and irreversibly blocks ADP binding, so the platelet is affected for its whole lifespan of about 7 to 10 days. Clopidogrel is not detected in human plasma. Between 20% and 40% of patients show low inhibition of ADP-induced platelet aggregation. ABCB1 takes part in intestinal absorption. Interactions have been reported with atorvastatin, verapamil and omeprazole.

    FDA continues to warn against concomitant use of clopidogrel and omeprazole because co-administration can significantly reduce levels of the active metabolite of clopidogrel and its antiplatelet activity; the warning was added to the Plavix label in November 2009. The recommendation applies only to omeprazole, not to all PPIs, because PPIs differ in inhibition of CYP2C19; pantoprazole, a weak CYP2C19 inhibitor, may be an alternative.

    Synthetic T4, chemically identical to thyroidal T4, indicated for primary, secondary and tertiary hypothyroidism and as an adjunct for TSH suppression in thyrotropin-dependent well-differentiated thyroid cancer. Narrow therapeutic index. Once daily on an empty stomach, half to one hour before breakfast, and at least 4 hours apart from drugs that interfere with absorption, including phosphate binders such as calcium carbonate and ferrous sulfate; gastric acidity is required for absorption, and proton pump inhibitors, sucralfate and antacids may reduce it. Absorption 40% to 80%, mostly in the jejunum and upper ileum, increased by fasting. T4 is 99.96% protein-bound; half-life 6 to 7 days in euthyroid patients, 9 to 10 days in hypothyroidism and 3 to 4 days in hyperthyroidism. About 80% of circulating T3 derives from peripheral monodeiodination of T4. Adult full replacement 1.6 mcg/kg/day, titrated by 12.5 to 25 mcg every 4 to 6 weeks; TSH is checked 6 to 8 weeks after a dose change; peak effect may take 4 to 6 weeks; in primary hypothyroidism the dose is titrated to a normal TSH, in secondary or tertiary hypothyroidism to free T4. Atrial fibrillation is the most common arrhythmia of overtreatment in the elderly; over-replacement may increase bone resorption and decrease bone mineral density, particularly in postmenopausal women. If cardiac symptoms develop or worsen, the dose is reduced or withheld for one week and restarted lower. Replacement therapy is generally taken for life.

    CYP2C19*2 (rs4244285) and *3 (rs4986893) are no-function and *17 (rs12248560) increased-function alleles; *2 has an allele frequency of about 15% in Europeans and Africans and 25% to 30% in Asians; *17 about 20% in African, European and Near Eastern populations. CYP2C19 accounts for about 80% of clearance of omeprazole, lansoprazole and pantoprazole, CYP3A4 for less. Intermediate and poor metabolisers have 3- to 14-fold higher AUC. For omeprazole, lansoprazole, pantoprazole and dexlansoprazole: ultrarapid metabolisers, increase the starting daily dose by 100%; normal and rapid metabolisers, standard dose, consider 50% to 100% increase for H. pylori infection and erosive oesophagitis; intermediate and poor metabolisers, standard dose, consider a 50% reduction for chronic therapy beyond 12 weeks once efficacy is achieved. No recommendation for esomeprazole and rabeprazole. Strong CYP3A inhibitors may raise risk in intermediate and poor metabolisers; strong CYP2C19 inhibitors such as fluvoxamine raise exposure except in poor metabolisers; inducers such as rifampin reduce exposure. Current data are insufficient for strong recommendations on adverse events; most studies were in Asian populations with few rapid and ultrarapid metabolisers.

    Weight loss: three randomised trials of gastric balloon against sham in severely obese people, with diet, exercise and behavioural therapy in both arms, reported reduced oesophageal acid exposure with weight loss (in one, 23 patients losing a mean 11.2 kg in 13 weeks went from 5.60% to 3.72% of time at pH < 4; in another, 17 sham-treated patients losing 12.5 kg went from 8.0% to 5.5% upright); in a trial of a structured weight-loss programme (n = 167) against telephone conferences (n = 165), reflux symptom prevalence fell from 37% to 15% after 6 months irrespective of group. A small randomised trial in obese patients with GERD (mean BMI 31.4), low-calorie diet of 430 kcal/day for 6 months (n = 10) against none (n = 9), found that a mean weight loss of 10.8 kg had no significant effect on symptoms, oesophagitis or pH measurements. Meal timing: crossover trial of 30 patients, late meal 2 hours before bedtime against early meal 6 hours before, more supine reflux after the late meal (mean change 5.2 percentage points). Head of bed: crossover trial of 15 patients, 10-inch wedge reduced time at pH < 4 from 21% to 15%. Smoking cessation reduced reflux symptoms in normal-weight people in a prospective cohort (OR 5.67). The authors note extensive data on acid-inhibiting medication against only few and heterogeneous trials of lifestyle intervention, consider commercial interests probably the main reason for this imbalance, and call for non-commercial funding of such trials.

    All five trials were at high risk of performance bias and four of selection bias; heterogeneity precluded meta-analysis. The four trials reporting symptoms found improvement with head-of-bed elevation; a high-quality crossover trial showed a clinically important reduction in symptom scores at 6 weeks (RR 2.1, 95% CI 1.2 to 3.6), supported by intra-oesophageal pH measurements. The authors judge that the literature precludes definitive recommendations but that elevation could be considered a cheap and safe alternative.

    Expert opinion and literature to July 2016, graded by a modified GRADE approach and reviewed by the AGA Clinical Practice Updates Committee. Patients with complicated GERD should take a PPI for healing, maintenance and long-term control; patients with uncomplicated GERD who respond should attempt to stop or reduce; patients with Barrett's oesophagus and symptoms should take a long-term PPI, asymptomatic patients should consider one; patients at high risk of NSAID ulcer bleeding should take a PPI; the dose should be periodically re-evaluated. Long-term users should not routinely use probiotics, raise intake of calcium, vitamin B12 or magnesium above the RDA, or be routinely screened or monitored for bone mineral density, serum creatinine, magnesium or vitamin B12; specific PPIs should not be chosen on the basis of potential risks.

    Severe hypomagnesaemia has been reported infrequently with PPIs; the exact incidence is unknown. A review of case reports in the literature and to European regulators suggests that PPIs may cause hypomagnesaemia; some cases occurred after 3 months and most after 1 year of treatment. Serious manifestations include fatigue, tetany, delirium, convulsions, dizziness and ventricular arrhythmia, which may begin insidiously and be overlooked. In most case reports hypomagnesaemia improved after magnesium replacement and discontinuation of the PPI. Magnesium measurement should be considered before and periodically during prolonged treatment, especially with digoxin or diuretics. Over-the-counter PPIs should not be used for more than 4 weeks without consulting a doctor.

    Not a systematic review; no formal rating of evidence quality. Best practice advice: every PPI user should have regular review and documentation of the indication by the primary care provider; patients without a definitive indication should be considered for a trial of de-prescribing; most twice-daily users with an indication should step down to once daily; complicated GERD, Barrett's oesophagus, eosinophilic oesophagitis or idiopathic pulmonary fibrosis and high upper gastrointestinal bleeding risk generally exclude de-prescribing; patients should be told they may develop transient symptoms from rebound acid hypersecretion; tapering or abrupt discontinuation can be considered. Advice 10: the decision to discontinue should be based solely on lack of an indication and not on concern for PPI-associated adverse events; a past or present adverse event or its risk factors is not an independent indication for withdrawal.
