Abstract
Proton pump inhibitors (PPIs) differ in onset of action and bioavailability. This trial was conducted to investigate the pharmacokinetics and pharmacodynamics of an immediate-release capsule formulation containing lansoprazole 30 mg and sodium bicarbonate 1100 mg (T preparation) in healthy Chinese subjects. This was an open, single-center, randomized, single and multiple oral doses, and two-period crossover study in 30 healthy subjects. After single- and multiple-dose oral administration, blood samples were obtained and lansoprazole concentration in serum was measured for pharmacokinetic analysis. Meanwhile, the intragastric pH was monitored continuously to evaluate the pharmacodynamics of the investigational drugs. The Tmax of the T preparation was 0.5 hours, while the Tmax of the R preparation was 1.5 hours after multiple doses, which indicated that the absorption speed of the T preparation was significantly faster than that of the R preparation. The same characteristics also existed after single-dose administration. The area under the curve (AUC)ss of the T preparation was bio-equivalent to that of the R preparation under steady state. The time percentage of intragastric pH > 4.0 for the T preparation was higher than that of the R preparation after 1 hour for both single- and multiple-dose. It suggested compared with R preparation, the time percentage of intragastric pH > 4.0 met the criteria for superiority after 1 hour administration for the T preparation. In addition, no serious adverse events occurred in this study. Across this study, the T preparation was better than the R preparation at improving drug absorption and increasing intragastric pH, and had a favorable safety profile.

Abstract
Heartburn and acid regurgitation are the typical symptoms of gastroesophageal reflux. Despite the availability of several treatment options, antacids remain the mainstay treatment for gastroesophageal reflux-related symptoms based on their efficacy, safety, and over-the-counter availability. Antacids are generally recommended for adults and children at least 12 years old, and the FDA recommends antacids as the first-line treatment for heartburn in pregnancy. This narrative review summarizes the mechanism, features, and limitations related to different antacid ingredients and techniques available to study the acid neutralization and buffering capacity of antacid formulations. Using supporting clinical evidence for different antacid ingredients, it also discusses the importance of antacids as OTC medicines and first-line therapies for heartburn, particularly in the era of the COVID-19 pandemic, in which reliance on self-care has increased. The review will also assist pharmacists and other healthcare professionals in helping individuals with heartburn to make informed self-care decisions and educating them to ensure that antacids are used in an optimal, safe, and effective manner.

Abstract
Gastroesophageal reflux disease (GERD) is a common disease worldwide, and its prevalence is increasing in both developed and developing countries. GERD is divided into three subtypes, namely, erosive esophagitis, nonerosive reflux disease (NERD), and Barrett's esophagus. The etiology, pathogenesis, clinical manifestations, and response to treatment of GERD invariably show high heterogeneity or significant individual difference, especially NERD and refractory GERD. On the other hand, advanced technology has currently provided a wide range of methods for the diagnosis and treatment of GERD patients; however, the long-term efficacy and quality of life of some patients are unsatisfactory. Therefore, each GERD patient needs a specialized management strategy aiming at his/her own condition, which is known as individualized medicine or personalized medicine. The goal of GERD treatment is to relieve the symptoms, while symptomatic remission is directly related to the quality of life. In other words, health-related quality of life and patient satisfaction may be reasonable criteria for GERD. In this paper, we will discuss the individualized medicine of GERD.

Abstract
In 2016, the new edition of the Council for International Organizations of Medical Sciences (CIOMS) Ethical Guidelines was released, which are universally acknowledged as ethical standards in biomedical research. In this article, we critically analyze the improvements and shortcomings of the CIOMS Ethical Guidelines 2016. Among the improvements are the relevance assigned to the social value of research and its effects on decision-making and the creation of public policies; the research development in low-resources scenarios; the communities involvement in the research process; the determination of participants vulnerability and changes on informed consent related proceedings. Despite the improved harmonization with scientific, technologic and social changes, and that the guidelines provide a tool for researchers and members of research ethics committees alike, some topics remain unsolved, namely the management of participants minimal risk and conflicts of interest involved in research, and the development of research in low-incomes scenarios. Nonetheless, we recognize that these new guidelines constitute a progress regarding the context and needs of populations in which research will be conducted, with greater community involvement in the different phases of the investigation project, thus allowing them to access the potential benefits. The impact of the CIOMS Ethical Guidelines 2016, should be appraised over time, particularly in socio-sanitary inequities scenarios and in the context of commercial interests of industry on biomedical research.

Abstract
The management of proton pump inhibitor-refractory GERD (rGERD) is a challenge in clinical practice. Since up to one-third of patients with typical GERD symptoms (heartburn and/or acid regurgitation) are not satisfied with proton pump inhibitor (PPI) therapy, new drug development targeting different pathophysiologies of GERD is imperative. At present, no other drugs serve as a more potent acid suppression agent than PPIs. As an add-on therapy, histamine type-2 receptor antagonists, alginates, prokinetics and transient lower esophageal sphincter relaxation inhibitors have some impact on the subgroups of rGERD, but greater effectiveness and fewer adverse effects for widespread use are required. Visceral hypersensitivity also contributes to the perception of GERD symptoms, and neuromodulators including antidepressants play a role in this category. Esophageal pH-impedance monitoring helps to distinguish functional heartburn from true GERD, and psychologic medication and cognitive behavior therapy are further therapy options instead of PPIs.

Abstract
Gastroesophageal reflux disease (GERD) is a common functional gastrointestinal disorder with significant effects on the quality of life. The burden of GERD is soaring in Asia. Preventing symptom relapse is a therapeutic goal in GERD patients. Since proton pump inhibitors (PPI) are the first-line treatment of GERD, drug failure has become a major problem in the treatment procedure. We reviewed the literature in order to find articles related to comorbidities and symptoms affecting GERD from 1980 to 2015 via PubMed and Google Scholar using keywords such as ‘Gastroesophageal reflux disease’, ‘Gastrointestinal symptoms’ and Boolean operators (such as AND, OR, NOT). Due to the cost of PPI therapy and the high rate of GERD relapse after PPI therapy, demand for continuing this type of treatment is decreasing. Thus, we need to discover new approaches to treat the disease and also investigate the relationship between the treatment of GERD and its comorbidities and symptoms such as functional constipation.

Abstract
Proton pump inhibitors (PPIs) effectively block gastric acid secretion and are the treatment of choice for heartburn. PPIs differ, however, in onset of action and bioavailability. In this single-center, open-label, three-way crossover study, onset of action of immediate-release omeprazole 20 mg/sodium bicarbonate 1100 mg (IR-OME) and delayed-release (DR) lansoprazole 15 mg was evaluated in 63 healthy fasting adults. Subjects were randomized to once daily IR-OME, or DR-lansoprazole, or no treatment for 7 days. The primary efficacy endpoint was the earliest time where a statistically significant difference was observed between IR-OME and DR-lansoprazole in median intragastric pH scores for three consecutive 5-min intervals on day 7. Secondary endpoints compared effects of active treatments on days 1 and 7 (e.g., time to sustained inhibition, percentage of time with pH >4). A significant difference in median intragastric pH favoring IR-OME was observed on day 7 starting at the 10- to 15-min interval postdosing (P = 0.024) and sustaining through the 115- to 120-min interval (P = 0.017). On day 1, IR-OME achieved sustained inhibition of intragastric acidity significantly faster than DR-lansoprazole. IR-OME maintained pH >4 significantly longer than DR-lansoprazole over a 24-h period (P = 0.007) on day 7. Overall, results of this study demonstrate IR-OME is safe and well tolerated and that treatment with IR-OME results in significantly faster onset of action and better gastric acid suppression at steady state than DR-lansoprazole.
