Objective: To provide an overview of pathophysiological changes to the pancreas during infected necrotizing pancreatitis (INP), optimal drug properties needed to penetrate the pancreas, human and animal studies supporting the use of antimicrobials, and carbapenem-sparing strategies in INP. Data Sources: A literature analysis of PubMed/MEDLINE was performed (from 1960 to September 2020) using the following key terms: infected necrotizing pancreatitis, necrotizing acute pancreatitis, and infected pancreatitis antimicrobial concentration. Individual antimicrobials were investigated with these search terms. Study Selection and Data Extraction: All relevant studies describing the management of INP, and human and animal pharmacokinetic (PK) data supporting antimicrobial use in the pancreas were reviewed for possible inclusion regardless of sample size or study design. Data Synthesis: Piperacillin/tazobactam and cefepime achieve adequate pancreatic tissue concentrations in INP studies. A majority of the literature supporting carbapenem use in INP involves imipenem, and meropenem Monte Carlo simulations suggest that standard dosing regimens of meropenem may not achieve PK targets to eradicate Pseudomonas aeruginosa. Relevance to Patient Care and Clinical Practice: Carbapenems are often utilized for INP treatment based on guideline recommendations. This review discusses PK data, the history of carbapenem use in INP, and the pathophysiology of pancreatitis to suggest carbapenem-sparing strategies and provides stewardship tactics such as when to start antimicrobials, which empirical antimicrobial to use, and when to discontinue antimicrobials in the INP setting. Conclusions: Noncarbapenem antipseudomonals, such as piperacillin/tazobactam and cefepime, are appropriate carbapenem-sparing options in INP, based on PK data, spectrum of activity, and risk of collateral damage.

OBJECTIVE: To review the evidence surrounding a potential association between liraglutide and pancreatitis. DATA SOURCES: A literature search was conducted in MEDLINE (1948-July 12, 2012) and EMBASE (1974-week 27, 2012) using the search terms pancreatitis, liraglutide, and glucagon-like peptide 1/adverse effects. Reference citations from identified publications were reviewed. The manufacturer was contacted and regulatory documents from the Food and Drug Administration website were reviewed for unpublished data related to cases of pancreatitis associated with liraglutide use. STUDY SELECTION AND DATA EXTRACTION: All identified sources that were published in English were considered for inclusion. DATA SYNTHESIS: Eleven cases of pancreatitis have been reported in patients taking liraglutide. Seven were from the LEAD (Liraglutide Effect and Action in Diabetes) studies, 1 was reported in the extension of a clinical trial, and 1 was in an unpublished obesity trial. Two were published postmarketing case reports. Nine of the cases reported were diagnosed as acute pancreatitis, while 2 were classified as chronic pancreatitis. The mean age of the patients was 57.5 years and mean body mass index was 33.92 kg/m2. Six of the 11 cases occurred in male patients. Nine of the patients were white and 1 was African American. In 7 of the cases, onset occurred at liraglutide doses at or above 1.8 mg daily. Common comorbidities included history of pancreatitis, cholelithiasis, and diabetes. One case was fatal. CONCLUSIONS: Pancreatitis is a potential complication with liraglutide therapy. Liraglutide should be used cautiously in patients at risk of pancreatitis (eg, alcohol abuse, history of pancreatitis, cholelithiasis).

AbstractThis review focuses on the efficacy of herbal medicines for managing dyspepsia in humans and animals. Searches were conducted on the PubMed, Science Direct, and Medline databases, for publications in the last 3 years. In each database, the search terms used consisted of the 2 key terms describing the disorder and subtypes plus each of the terms relating to the therapy. The key terms used were “natural product” and “medicinal plant” in a cross-over with “dyspepsia” and “functional dyspepsia” (i.e., gastroprotection, Helicobacter pylori infection, prokinetic). We included all human and animal studies on the effects of herbal medicines reporting the key outcome of dyspepsia symptoms. Preclinical studies using critically validated models showed that most medicinal plants with gastroprotective action had antioxidant, anti-inflammatory, anti-apoptotic, and antisecretory effects. Moreover, several species displayed anti Helicobacter pylori and prokinetic efficacy. The data availability of controlled clinical studies is currently minimal. The use of different methodologies and the minimal number of patients raise doubts about the effects of these preparations. Only adequate clinical trials with scientifically validated methods can determine whether different herbal medicines can be used as viable alternatives to the conventional pharmacological treatments used to control dyspepsia symptoms.

Objective: To synthesize the evidence from systematic reviews of clinical trials investigating the effectiveness of pharmacological therapies approved by the Australian Therapeutic Goods Administration and the US Food and Drug Administration for the management of obesity in adults. Data Sources: A 3-step literature search of the MEDLINE, EMBASE, CINAHL, and PubMed databases was conducted between March and May 2019. The key terms used were obesity, pharmacological therapy, antiobesity agent, antiobesity medication, weight loss, and systematic review. Study Selection and Data Extraction: Systematic reviews that evaluated the effectiveness of pharmacological therapies for the management of obesity in patients with a body mass index of or greater than 25 kg/m2. Data Synthesis: Nine systematic reviews involving three pharmacotherapies, liraglutide, orlistat, and naltrexone-bupropion were identified. The results indicate that the pharmacotherapies reduced weight when compared with placebo. Orlistat was effective in significantly reducing fasting blood glucose, HbA1c, total cholesterol, triglycerides, and systolic and diastolic blood pressure. All reviews discussed the presence or risk of gastrointestinal adverse effects including diarrhea, vomiting, and nausea related to orlistat and liraglutide. Relevance to Patient Care and Clinical Practice: This umbrella review compares the efficacy and safety of antiobesity medications for reducing weight and a discussion on their weight loss and metabolic control to guide clinicians when prescribing medications for obesity. Conclusions: All pharmacological therapies included in this review are superior to placebo in reducing weight. Clinicians should consider patient comorbidities and risk of adverse events when recommending medications for weight loss.

BackgroundThe health status and needs of indigenous populations of Australia, Canada and New Zealand are often compared because of the shared experience of colonisation. One enduring impact has been a disproportionately high rate of commercial tobacco use compared with non-indigenous populations. All three countries have ratified the WHO Framework Convention on Tobacco Control (FCTC), which acknowledges the harm caused to indigenous peoples by tobacco.Aim and objectivesWe evaluated and compared reporting on FCTC progress related to indigenous peoples by Australia, Canada and New Zealand as States Parties. The critiqued data included disparities in smoking prevalence between indigenous and non-indigenous peoples; extent of indigenous participation in tobacco control development, implementation and evaluation; and what indigenous commercial tobacco reduction interventions were delivered and evaluated.Data sourcesWe searched FCTC: (1) Global Progress Reports for information regarding indigenous peoples in Australia, Canada and New Zealand; and (2) country-specific reports from Australia, Canada and New Zealand between 2007 and 2016.Study selectionTwo of the authors independently reviewed the FCTC Global and respective Country Reports, identifying where indigenous search terms appeared.Data extractionAll data associated with the identified search terms were extracted, and content analysis was applied.ResultsIt is difficult to determine if or what progress has been made to reduce commercial tobacco use by the three States Parties as part of their commitments under FCTC reporting systems. There is some evidence that progress is being made towards reducing indigenous commercial tobacco use, including the implementation of indigenous-focused initiatives. However, there are significant gaps and inconsistencies in reporting. Strengthening FCTC reporting instruments to include standardised indigenous-specific data will help to realise the FCTC Guiding Principles by holding States Parties to account and building momentum for reducing the high prevalence of commercial tobacco use among indigenous peoples.

OBJECTIVE: To present the pharmacology and pharmacokinetics of nelarabine, 9-β-D-arabinofuranosylguanine (ara-G) and intraleukemic cellular pharmacokinetics of 9-β-D-arabinofuranosylguanine triphosphate (ara-GTP) generated from the administration of nelarabine, and clinical and safety information relative to nelarabine use in the treatment of hematologic malignancies. DATA SOURCES: MEDLINE (1966—December 2004) was searched using the English-language key terms 2-amino-6-methoxypurine arabinoside, 506U78, and nelarabine. Data were also obtained from published abstracts. STUDY SELECTION AND DATA EXTRACTION: Clinical studies evaluating the pharmacokinetics of nelarabine, ara-G, and cellular ara-GTP and use of nelarabine, alone or in combination with other agents for the treatment of hematologic malignancies, were included in this review. DATA SYNTHESIS: Nelarabine is the water-soluble, 6-methoxy analog of 9-β-D-ara-G. Nelarabine is readily converted to ara-G by endogenous adenosine deaminase. The half-life of nelarabine is approximately 15 minutes compared with 2–4 hours for ara-G. The clearance of ara-G is higher in children than in adults (0.312 vs 0.213 L × h−1 × kg−1). Intracellular ara-GTP elimination is slow relative to nelarabine and ara-G. In pediatric and adult patients, neurologic toxicity is dose limiting. Severe myelosuppression was not consistently observed. Major responses were seen in patients with T-cell malignancies. Patients who responded had significantly higher intracellular ara-GTP concentrations compared with those who did not respond. CONCLUSIONS: Nelarabine is an effective ara-G prodrug. Nelarabine has significant activity against malignant T-cells and appears to be an important addition to treatments of various leukemias.

Objective: To review the literature discussing the use of dexrazoxane (e.g., Zinecard, ICRF-187) to prevent doxorubicin-induced cardiotoxicity. Data Sources: Pertinent English-language reports of studies in humans were retrieved from a MEDLINE search (January 1980-January 1997); search terms included chelating agents, razoxane, dexrazoxane, Zinecard, ICRF-187, ADR-529, and ICRF-159. Study Selection: Representative articles discussing the chemistry, pharmacology, pharmacokinetics, dosing, and administration of dexrazoxane and those discussing clinical trials were selected. Data Extraction: Data were extracted and analyzed if the information was relevant and consistent. Studies were selected for review in the text on the basis of study design and clinical end points. Data Synthesis: Dexrazoxane is a chemoprotective agent developed to prevent cardiac tissue toxicity. Dexrazoxane exerts a cardioprotective effect with some clinically significant toxicities; it may also interfere with the antitumor activity of doxorubicin. Until there are sufficient data to support its use in first-line supportive care therapy, dexrazoxane should be reserved for use in patients responding to doxorubicin-based chemotherapy but who have risk factors for cardiac toxicity or have received a cumulative doxorubicin bolus dose of 300 mg/m2. Conclusions: The management of doxorubicin-induced cardiotoxicity has led to the development of supportive care drugs that specifically counteract the dose-limiting toxicities. Dexrazoxane may not completely eliminate the concern about doxorubicin-induced cardiotoxicity, but it may open new avenues for continuing doxorubicin-based chemotherapy.

Objective: To describe the pharmacology, efficacy, and safety of stiripentol in the treatment of refractory seizures in patients with Dravet syndrome. Data Sources: A search of the English language literature was conducted using PubMed and MEDLINE (1978 to April 2019) with the search terms stiripentol, Dravet syndrome, and refractory epilepsy. Other resources included article bibliographies, prescribing information, and relevant trials at https://clinicaltrials.gov/ . Study Selection and Data Extraction: All phase 1, 2, or 3 trials; observational studies; and retrospective studies were analyzed. Data Synthesis: In controlled studies, stiripentol has been shown to reduce seizure frequency by 50% or more in 40% to 70% of patients with Dravet syndrome. Reductions in seizure duration and episodes of status epilepticus have also been documented. Common adverse effects include somnolence and anorexia. Stiripentol inhibits the metabolism of clobazam and valproate, often requiring dose adjustment. Relevance to Patient Care and Clinical Practice: Stiripentol, a direct allosteric modulator of GABAA receptors, offers a novel approach to treatment in patients with Dravet syndrome, both with and without pathogenic variants of the sodium channel α-1 subunit gene, and potentially other refractory seizures. Although available outside the United States for a decade, it was only recently approved by the Food and Drug Administration for patients 2 years of age and older with Dravet syndrome taking clobazam. Conclusions: Stiripentol is an effective adjunctive therapy for reducing the frequency and duration of refractory seizures in patients with Dravet syndrome. Its role in the treatment of other refractory epilepsies requires further study.

Objective: To describe properties of cobicistat and ritonavir; compare boosting data with atazanavir, darunavir, and elvitegravir; and summarize antiretroviral and comedication interaction studies, with a focus on similarities and differences between ritonavir and cobicistat. Considerations when switching from one booster to another are discussed. Data Sources: A literature search of MEDLINE was performed (1985 to April 2017) using the following search terms: cobicistat, ritonavir, pharmacokinetic, drug interactions, booster, pharmacokinetic enhancer, HIV, antiretrovirals. Abstracts from conferences, article bibliographies, and product monographs were reviewed. Study Selection and Data Extraction: Relevant English-language studies or those conducted in humans were considered. Data Synthesis: Similar exposures of elvitegravir, darunavir, and atazanavir are achieved when combined with cobicistat or ritonavir. Cobicistat may not be as potent a CYP3A4 inhibitor as ritonavir in the presence of a concomitant inducer. Ritonavir induces CYP1A2, 2B6, 2C9, 2C19, and uridine 5′-diphospho-glucuronosyltransferase, whereas cobicistat does not. Therefore, recommendations for cobicistat with comedications that are extrapolated from studies using ritonavir may not be valid. Pharmacokinetic properties of the boosted antiretroviral can also affect interaction outcome with comedications. Problems can arise when switching patients from ritonavir to cobicistat regimens, particularly with medications that have a narrow therapeutic index such as warfarin. Conclusions: When assessing and managing potential interactions with ritonavir- or cobicistat-based regimens, clinicians need to be aware of important differences and distinctions between these agents. This is especially important for patients with multiple comorbidities and concomitant medications. Additional monitoring or medication dose adjustments may be needed when switching from one booster to another.

Objective: To determine the strength of the evidence evaluating the effectiveness of intrapulmonary percussive ventilation (IPV) as a safe alternative or adjunctive therapy to traditional chest physiotherapy (CPT) among potential organ donors. Data Sources: Literature search conducted from February 2015 to November 2015 using PubMed, Cumulative Index of Nursing and Allied Health Literature, Scopus, and bibliographies of pertinent articles. Search Terms: Intrapulmonary percussive ventilation, chest physiotherapy, chest wall oscillation, organ donors, and ventilation. Study Selection: Articles in English from 1994 to present directly compared IPV to CPT or conventional (no) therapy. Data Extraction: Association of Critical-Care Nurses Levels of Evidence was used to determine the strength of evidence. Level B and level C articles were reviewed. Data Synthesis: No studies were found using IPV in the donor population. Results from studies using IPV in other populations indicated IPV had no adverse effects, improved sputum clearance and oxygenation, and reduced atelectasis and pneumonia in patients with artificial airways. Conclusion: Intrapulmonary percussive ventilation may be a safe and effective alternative or adjunctive to CPT therapy and improve the number of lungs available for transplantation. Clinical research is essential to determine the effectiveness of this therapy for lung recruitment in the donor population.

Objective: To review the current literature on drug-induced yawning. Data Sources: Literature was accessed through MEDLINE/PubMed (1996-July 2011), International Pharmaceutical Abstracts (1997-July 2011), and EMBASE, using the search terms yawning, drug-induced yawning, and adverse drug reactions. Study Selection and Data Extraction: Relevant clinical trials and case reports were selected and included to present background information. Bibliographies of all relevant articles were reviewed for additional citations. Data Synthesis: Yawning is a common stereotype behavior with unknown physiologic function that occurs in most vertebrates and humans as early as 15 weeks of intrauterine life. Yawning Is under the control of several neurotransmitters and neuropeptides, Including dopamine, serotonin, oxytocin, and acetylcholine. Among drugs, antidepressants, opioids, dopaminergic agents, benzodiazepines, and induction agents are the main pharmacologic classes associated with yawning. Conclusions: Yawning is rarely a serious adverse reaction and is not frequently listed in the drug summary. Most available data are based on case reports, small studies, and older literature. Clinicians should be aware of the agents commonly triggering this behavior.
