What You Need to Know Before You Apply

What is the purpose of this trial?

Thoracic radiation therapy combined with chemotherapy (with or without immunotherapy) is the cornerstone of management in patients with locally advanced non-small cell lung cancer (NSCLC).

Will I have to stop taking my current medications?

If you are currently taking clopidogrel, nelfinavir, rilpivirine, methotrexate, rifampin, digoxin, tacrolimus, or phenytoin, you will need to stop these medications as they may interact with esomeprazole.

Is esomeprazole generally safe for human use?

Esomeprazole is generally well-tolerated in humans, with side effects similar to those of omeprazole, another common medication for acid-related disorders. Clinical trials have shown it to be safe for use in treating conditions like gastroesophageal reflux disease and erosive esophagitis. ^{1 2 3 4 5}

How is the drug esomeprazole different from other treatments for esophagitis?

Esomeprazole is unique because it is the S-isomer of omeprazole, providing better control of stomach acid and more effective healing of erosive esophagitis compared to other proton pump inhibitors like omeprazole and lansoprazole. It also has an improved pharmacokinetic profile, meaning it is absorbed and processed by the body more consistently, leading to more reliable results. ^{1 3 6 7 8}

What data supports the effectiveness of the drug Esomeprazole for treating esophagitis?

A study showed that esomeprazole is effective in healing severe forms of reflux esophagitis (a condition where the esophagus becomes inflamed due to acid reflux) over a 6-month period, especially in patients with certain genetic factors. ^{9 10 11 12 13}

In a study of 113 patients with reflux esophagitis grades C and D, esomeprazole 40 mg daily for 6 months was effective in promoting healing, regardless of the patients' CYP2C19 genotypes.

A higher body mass index (BMI) over 25 kg/m² was linked to lower healing rates, while reducing BMI by more than 1.5 kg/m² significantly improved healing outcomes, suggesting weight management could enhance treatment efficacy.

In a study of 188 patients with acromegaly, factors such as IGF-I levels, weight, height, and age were found to significantly predict the optimal dose of pegvisomant (PEGV) needed to normalize IGF-I levels when used alongside long-acting somatostatin analogues (LA-SSAs).

For patients receiving PEGV as monotherapy, only weight was a significant predictor of the required dose, indicating that dosing strategies may need to be tailored based on individual patient characteristics.

Pegvisomant was found to be significantly more effective than octreotide in suppressing the growth hormone (GH) axis, achieving up to 62% suppression of total IGF-I levels after 14 days of treatment in 80 healthy subjects.

The safety profile of pegvisomant was favorable, with most adverse events being mild (grade 1 or 2), including injection site reactions, headache, and fatigue, suggesting it could be a viable option for treating GH-dependent tumors.

Long-term treatment combining somatostatin analogs (SSA) and pegvisomant (PEG-V) in 86 acromegalic patients over an average of 29.2 months appears to be safe, with manageable side effects.

A significant number of patients (14) experienced tumor shrinkage of more than 20% during this combined therapy, indicating its efficacy in reducing tumor size in acromegaly.

The study identified new alpha(2)-adrenergic receptor ligands that show significant agonism at alpha(2C) receptors and antagonism at alpha(2A) receptors, which could enhance morphine's pain-relieving effects.

Compounds 8 and 11 may serve as beneficial adjuvants in pain management, potentially improving analgesia while reducing sedation associated with morphine use.

Esomeprazole sodium remains chemically and physically stable for at least 2 days at room temperature and 5 days when refrigerated, making it suitable for short-term infusion use.

The study found no significant loss of drug content (less than 7%) in esomeprazole samples across various infusion solutions, indicating its reliability for treating gastroesophageal reflux disease.

In a study of 47 mechanically ventilated patients at high risk for stress ulcers, intravenous esomeprazole effectively maintained gastric acidity above pH 5 and prevented bleeding of the gastric mucosa, demonstrating its safety and efficacy as a preventive treatment.

No instances of gastric mucosal bleeding were observed, and the study suggests that esomeprazole could be a reliable option for preventing stress ulcers in ICU patients, although further comparative studies with other treatments are needed.

Esomeprazole is more effective than omeprazole and lansoprazole in healing erosive esophagitis and resolving heartburn, as shown in large trials where patients took esomeprazole 40 mg daily for 8 weeks.

It is well-tolerated and has a similar safety profile to omeprazole, with effective maintenance of healed erosive esophagitis over 6 to 12 months, and it also effectively eradicates Helicobacter pylori when used in combination therapy.

Esomeprazole (Nexium) is more effective than other proton pump inhibitors in controlling stomach acid, maintaining a higher intragastric pH for longer periods in patients with gastroesophageal reflux disease after just 5 days of treatment.

In clinical trials, esomeprazole 40 mg once daily for up to 8 weeks resulted in higher healing rates of erosive esophagitis and better heartburn resolution compared to omeprazole and lansoprazole, making it a strong option for treating acid-related disorders.

In a study of 1904 patients with symptoms of gastroesophageal reflux disease (GERD), continuous daily treatment with esomeprazole 20 mg provided slightly better relief from heartburn compared to on-demand treatment.

However, the on-demand use of esomeprazole 20 mg resulted in lower direct medical costs, making it a more economical option while still being well tolerated by patients.

Esomeprazole (40 mg) is more effective than omeprazole (20 mg) in healing reflux oesophagitis, with higher healing rates observed at both 4 weeks (relative risk 1.14) and 8 weeks (relative risk 1.08) based on a systematic review of randomized controlled trials.

Other proton pump inhibitors like lansoprazole, pantoprazole, and rabeprazole did not show superior healing rates compared to omeprazole, indicating that esomeprazole may be a preferred option for treating this condition.

Esomeprazole, a proton pump inhibitor, is more effective than omeprazole in controlling stomach acid and treating erosive esophagitis in patients with GERD.

The safety profile of esomeprazole is comparable to that of omeprazole, with infrequent adverse events, making it a reliable option for both healing erosive esophagitis and eradicating Helicobacter pylori infections.

Esomeprazole 40mg once daily is significantly more effective than omeprazole 20mg once daily for healing reflux oesophagitis, with healing rates of 93.4% versus 86.2% after 8 weeks, respectively.

The treatment with esomeprazole also results in cost savings of £1290 (14%) over 8 weeks compared to omeprazole, making it a more cost-effective option for the acute treatment of this condition.
