From the database's inception until February 2023, a systematic search was conducted in PubMed, Embase, the Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang Database, and China Science and Technology Journal Database to identify randomized controlled trials (RCTs) comparing the efficacy of oral semaglutide at dosages of 3, 7, and 14 mg (trial group) against placebo or other positive control drugs (control group) for the treatment of T2DM. Following literature screening and data extraction, the bias risk assessment tool in the Cochrane reviewer handbook 5.1.0 was used to evaluate the literature quality. Meta-analysis was carried out with RevMan 5.4 software. A total of 10 RCTs with 9541 patients were included. The meta-analysis results revealed that compared with placebo or positive control drugs (empagliflozin, sitagliptin, liraglutide, and dulaglutide), oral semaglutide significantly reduced the hemoglobin A1c (HbA1c) in patients (compared to placebo, 3 mg [MD = −0.61%, 95% CI (−0.89, −0.34)], 7 mg [MD = −1.12%, 95% CI (−1.45, −0.79)], 14 mg [MD = −1.08%, 95% CI (−1.32, −0.85)]; compared to positive control drugs (7 mg [MD = −0.26%, 95% CI (−0.38, −0.15)], 14 mg [MD = −0.37%, 95% CI (−0.52, −0.23)]). Oral semaglutide also showed certain advantages over placebo or positive control drugs in terms of weight loss, HbA1c reduction achievement rate, fasting plasma glucose level, and body mass index with overall dose-dependent efficacy. The incidence of nausea, diarrhea, and vomiting caused by oral semaglutide was higher than that of the placebo or positive control drugs, and the incidence of appetite decrease or constipation was higher than that of the placebo.

Our sentence that reads, “Fortunately, there were no reported seizures in any of the published cases after baclofen initiation” likely did not express our intended message.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; This statement meant to convey that there were no reported seizures &lt;i&gt;that appeared to be precipitated by baclofen&lt;/i&gt; in any of the published cases. This leads into our next sentence, which reads, “However, given the known risk for seizures with baclofen, caution should be taken when it is used.” We appreciate the opportunity to make this clarification. As Dr. Feldman also notes, later in our article we discuss the case report by Patt et al. (on which Dr. Feldman is a coauthor) and note that their patient experienced a tonic–clonic seizure within 28 h of being discharged on baclofen monotherapy at 10 mg thrice daily.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; This relatively low dose of baclofen was an unlikely cause of this patient's seizure; the seizure was almost certainly precipitated by acute phenibut withdrawal in the absence of anticonvulsant prophylaxis with a benzodiazepine or phenobarbital.&lt;/p&gt;&lt;p&gt;Dr. Feldman also takes exception to the following statement in Table 1 of our paper: “(Baclofen) has been used successfully alone and in combination (usually with a benzodiazepine) for the treatment of phenibut withdrawal.”&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; Dr. Feldman states that “the phrasing in this table could be interpreted to suggest baclofen monotherapy for patients admitted to handle acute withdrawal during the initial phases of abstinence.” As Dr. Feldman correctly explains, there are different stages of phenibut withdrawal: an acute abstinence period followed by a postacute period after the patient has stabilized. Our comment in Table 1 is a comprehensive statement pertaining to the general syndrome of phenibut withdrawal; it was not intended to differentiate between acute and postacute phenibut withdrawal scenarios. We made this clear in our review, which states, “Based on currently available data, the combination of baclofen and a benzodiazepine such as diazepam or lorazepam represents a logical therapeutic approach for treating patients experiencing acute phenibut withdrawal. Once severe symptoms are under control, it may be possible to taper off the benzodiazepine and treat the patient with baclofen monotherapy, using a prolonged taper (ie, over a period of months).”&lt;/p&gt;&lt;p&gt;Lastly, Dr. Feldman appears to suggest that we have placed too much emphasis on a report by Samokhvalov et al., which describes a case where 8-10 mg of baclofen was substituted per 1 g of phenibut to successfully treat a patient experiencing phenibut withdrawal.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; Consistent with Dr. Feldman's comments, and as stated in our review, “…there are no published data on the dose equivalency between phenibut and baclofen.” We go on to state, “&lt;i&gt;If&lt;/i&gt; this","PeriodicalId":22751,"journal":{"name":"The Journal of Clinical Pharmacology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jcph.2480","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141238525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ChatGPT was asked 264 questions in all, and its answers were assessed for accuracy, consistency, substantiation quality, and repeatability. According to the findings, ChatGPT answered 79% of the questions correctly, outperforming pharmacists' accuracy rate of 66%. The agreement between ChatGPT's answers and the right answers was 95%. The fact that ChatGPT's performance was assessed using only 264 questions is one of the study's weaknesses. This might not adequately convey the limitations and strengths of the approach for a wider range of clinical pharmacy subjects. Furthermore, the study only included factual knowledge questions, which might not accurately capture the subtleties and complexities that are frequently present in clinical practice. Additionally, there might have been biases in the questions chosen or the standards of evaluation that the researchers employed. The lack of variety in the questions that are sent to ChatGPT and the possibility of irregularities in the independent pharmacists' evaluation of the substantiation's quality are two specific methodological shortcomings. Furthermore, when applying clinical pharmacy knowledge to real-world circumstances, ChatGPT's interpretative or reasoning abilities were not examined in this study. These elements are necessary for a thorough assessment of ChatGPT's usefulness in clinical settings. Extending the dataset of questions to include a greater variety of clinical pharmacy issues, including more intricate and nuanced scenarios, may be one of the research's future approaches. Furthermore, more research into ChatGPT's capacity to offer justifications and explanations for its conclusions might improve the tool's suitability for helping pharmacists make decisions. Studies with a longitudinal design could investigate ChatGPT's long-term effectiveness and evaluate how it affects clinical outcomes in pharmacy practice.

To inform the pediatric program of CHILD-IVITAB, 16 healthy adults were enrolled in a phase I, single-center, open-label, randomized, 2-period, crossover, single-dose trial which aimed to compare palatability, tolerability, and bioavailability and pharmacokinetics of CHILD-IVITAB and their variability against the marketed ivermectin tablets (STROMECTOL) at a single dose of 12 mg in a fasting state.
