Fat Soluble Vitamins

Objective: To evaluate the safety and efficacy of current pharmacotherapeutic options for weight loss in overweight adolescents. Data Sources: Literature was obtained through MEDLINE Ovid (1996–April 2007) and EMBASE Drugs and Pharmacology (1991–2nd quarter 2007) searches and a bibliographic review of published articles. Key words included adolescents, overweight, obesity, anti-obesity agents, drug therapy, orlistat, sibutramine, and metformin. Study Selection and Data Extraction: All studies published in the English language that evaluated the use of pharmacotherapy for the treatment of overweight adolescents were critically analyzed; pertinent articles were selected for this review. Data Synthesis: Orlistat has been approved for use in adolescents between the ages of 12 and 16 years. The most frequently reported adverse effects of orlistat were gastrointestinal; reduced concentrations of fat-soluble vitamins were also observed. Of the 6 clinical trials published, 5 have shown statistically significant reductions in body mass index {BMI) from baseline, ranging from 0.55 to 4.09 kg/m2; one small trial failed to demonstrate significant weight reduction compared with placebo. Sibutramine has also been evaluated for use in overweight adolescents in 6 trials. Trials demonstrated a statistically significant reduction in BMI up to 5.6 kg/m2 (from baseline). Of concern is evidence indicating that sibutramine therapy may be associated with elevated blood pressure, increased pulse rate, depression, and suicidal ideations. Lastly, metformin has recently been evaluated for weight loss in overweight adolescents; small, short-term trials demonstrate modest reductions in weight and BMI. Conclusions: Orlistat has been proven both safe and effective for weight reduction in overweight adolescents. Sibutramine has also been proven effective in reducing weight in this population; however, the potential for severe adverse effects requires further investigation. Metformin has demonstrated promising results in small trials; its role in the treatment of overweight adolescents will remain investigational until further research is conducted.

New Treatment

OBJECTIVE: To review the pharmacology, pharmacokinetics, clinical efficacy, adverse effects, drug interactions and precautions, and dosing recommendations of rifaximin, a new nonabsorbed antimicrobial agent for travelers' diarrhea. DATA SOURCES: A MEDLINE search (1966–July 2004) was conducted to extract human and animal research data in the English language on rifaximin. STUDY SELECTION AND DATA EXTRACTION: Randomized, double-blind, placebo-controlled trials were reviewed and included to evaluate the efficacy of rifaximin in the treatment of travelers' diarrhea. DATA SYNTHESIS: Rifaximin is approved for the treatment of travelers' diarrhea in patients ≥12 years of age with diarrhea caused by noninvasive strains of Escherichia coli. Rifaximin was superior to placebo and trimethoprim/sulfamethoxazole and equivalent to ciprofloxacin in the primary clinical endpoint of the time to the last unformed stool passed. CONCLUSIONS: Rifaximin is a viable alternative to ciprofloxacin for the treatment of travelers' diarrhea. As rifaximin is not systemically absorbed, it offers the advantage of leading to the development of less resistance compared with systemically absorbed antibiotics, in addition to fewer systemic adverse effects and drug interactions. However, the potential for cross-resistance between rifaximin and rifampin, as well as with other classes of antibiotics, is of concern and needs to be elucidated.

OBJECTIVE: TO review the literature that compares Zolpidem with triazolam, with an emphasis on efficacy and safety in humans. DATA SOURCES: Information was retrieved from a MEDLINE search (1983–1996) of the English-language literature using the terms triazolam and zolpidem. STUDY SELECTION: Reports of clinical trials comparing the safety and efficacy of zolpidem and triazolam were included in this review. DATA EXTRACTION: Data were evaluated according to study design, efficacy, and adverse effects. Pertinent information was selected and the data synthesized into a review format. DATA SYNTHESIS: Zolpidem and triazolam have similar pharmacokinetic and pharmacodynamic effects in humans. Clinical trials have shown that usually recommended, equipotent dosages of zolpidem and triazolam do not differ with respect to pharmacokinetics, efficacy, tolerability, residual effects, memory impairment, rebound insomnia, abuse potential, or other adverse effects. CONCLUSIONS: Zolpidem offers no distinct therapeutic advantage over triazolam for the treatment of insomnia.

Antiobesity Agents

Objective: To assess the safety and efficacy of FDA-approved and in-development antiobesity agents. Data Sources: Literature was accessed through MEDLINE (1950-current) and EMBASE using the terms antiobesity agent, diethylpropion, phentermine, orlistat, topiramate, lorcaserin, bupropion, and naltrexone. In addition, reference citations from publications identified were reviewed. Files related to FDA expert panel hearings were retrieved from the FDA website. Study Selection and Data Extraction: Randomized double-blind trials assessing the efficacy and safety of antiobesity agents compared with placebo in the treatment of overweight and obese adults were reviewed. Only English-language or English-translated literature was reviewed. Medications were selected based on FDA approval status. Data Synthesis: Ten double-blind clinical trials were reviewed. There are currently 5 FDA-approved antiobesity agents and 1 agent recently rejected by the FDA. Study results for all agents showed statistically significant weight loss compared with placebo, but with varying adverse effects. The combination of phentermine and topiramate is the most efficacious antiobesity agent approved by the FDA. However, this combination has various neurologic, cardiovascular, and teratogenic safety risks that may limit its use. Based on its safety profile, orlistat is the preferred antiobesity medication, despite the lesser extent to which it induces weight loss versus newer agents. The incidence of unwanted gastrointestinal adverse effects limits its use. Conclusions: Despite a glaring medical need for options to treat obesity, available medications are limited. No current drug option is ideal; each has either safety risks or efficacy concerns. Safe agents that meet FDA efficacy standards are needed to help treat the obesity epidemic.

Objective: To review the incidence, risk factors, and management of pegfilgrastim-induced bone pain (PIBP). Data Sources: PubMed was searched from 1980 to March 31, 2017, using the terms pegfilgrastim and bone pain. Study Selection and Data Extraction: English-language, human studies and reviews assessing the incidence, risk factors, and management of PIBP were incorporated. Data Synthesis: A total of 3 randomized, prospective studies and 2 retrospective studies evaluated pharmacological management of PIBP. Naproxen compared with placebo demonstrated a reduction in the degree, incidence, and duration of bone pain secondary to pegfilgrastim. Loratadine was not effective in reducing the incidence of bone pain prophylactically, but a retrospective study evaluating dual antihistamine blockade with loratadine and famotidine demonstrated a decreased incidence in bone pain when administered before pegfilgrastim. Conclusion: Naproxen is effective at managing PIBP. Although commonly used, antihistamines have a paucity of data supporting their use. Dose reductions of pegfilgrastim and opioids may also be potential management options; however, data supporting these treatment modalities are scarce.

OBJECTIVE: To review the current published clinical studies evaluating the clinical efficacy and safety of lactulose compared with other laxatives or placebo. Adverse effects associated with lactulose are also reported. DATA SOURCES: Information was retrieved by searching the MEDLINE and EMBASE databases for clinical trials, abstracts, conference proceedings, and review articles dealing with lactulose. STUDY SELECTION: Emphasis was placed on clinical trials where lactulose was compared with other laxatives or placebo in patient populations where the diagnosis of constipation was reasonably established. DATA EXTRACTION: The methodology and results from clinical studies were evaluated. Assessment of the studies was made based on diagnosis of constipation, prior management of patients, follow-up of patients, dosage, and adverse effects. DATA SYNTHESIS: Clinical trials in geriatric patients, terminally ill patients, children, and normal and constipated subjects were reviewed. In most instances, lactulose was compared with a placebo, without incorporating the current education on dietary techniques for improving defecation. CONCLUSIONS: Generally, clinical trials have demonstrated a beneficial response compared with placebo, although sometimes that response has been only marginally better, from a clinical point of view.

Objective To review the pharmacology, efficacy, and safety of high-dose once-weekly semaglutide for chronic weight management. Data Sources PubMed/MEDLINE and ClinicalTrials.gov were searched (inception to September 8, 2021) using keywords “semaglutide” and “obesity,” “weight,” “high dose,” “high-dose,” or “2.4.” Study Selection and Data Extraction Clinical trials with published results were included. Publications studying the oral or <2.4 mg formulation of semaglutide were excluded. Data Synthesis Four phase 3, multicenter, randomized, double-blind trials demonstrated efficacy of high-dose once-weekly semaglutide compared with placebo for weight loss. Study populations included patients with overweight or obesity (STEP 1, STEP 3, and STEP 4) or patients with diabetes and with overweight or obesity (STEP 2). Lifestyle interventions for diet and exercise were included for all participants. Weight loss from baseline was significant for all studies, and secondary outcomes demonstrated cardiometabolic improvements including waist circumference, systolic blood pressure, and lipid profiles. Gastrointestinal adverse effects were common, but the medication was otherwise well tolerated. Relevance to Patient Care and Clinical Practice High-dose semaglutide offers significant weight-lowering potential and favorable effects on cardiometabolic risk factors and glycemic indices. Clinicians and patients should consider the route and frequency of administration, adverse effect profile, and cost when choosing an antiobesity medication. The importance of concomitant lifestyle interventions should be emphasized. Conclusions High-dose once-weekly semaglutide can significantly reduce weight, and although gastrointestinal adverse effects were common, it is generally well tolerated.

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.

Objective: To review the safety, efficacy, and administration of intranasal (IN) glucagon for the management of hypoglycemia. Data Source: A literature search of PubMed/MEDLINE (1995 to November 2019) using the terms intranasal glucagon, nasal glucagon, glucagon, hypoglycemia treatment, and hypoglycemia management was completed. Study Selection and Data Extraction: English-language studies evaluating IN glucagon were evaluated. Data Synthesis: IN glucagon is a newly approved product for the treatment of hypoglycemia in patients with diabetes, 4 years and older. Administered as a 3-mg dose, it was shown to be noninferior to intramuscular (IM) glucagon. In comparison trials, more than 98% of hypoglycemic events were treated successfully with IN glucagon in both pediatric and adult patients. In simulated and real-world studies, IN glucagon was administered in less than a minute for the majority of scenarios. IM glucagon took longer to administer, ranging from 1 to 4 minutes, and often, patients did not receive the intended full dose. Nausea and vomiting, known adverse events for glucagon, as well as local adverse events were most commonly reported with IN glucagon. Relevance to Patient Care and Clinical Practice: IN glucagon is safe, effective, easy to use, and does not require reconstitution prior to use, which can lead to faster delivery in a severe hypoglycemic event. It does not require age- or weight-based dosing. This delivery method offers an option for someone who fears needles or is uncomfortable with injections. Conclusion: IN glucagon is a safe, effective, easy to use, needle-free treatment option for severe hypoglycemia.

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.
