Objective: To review the pharmacology, pharmacokinetics, efficacy, and safety of fingolimod, a novel immune modulator. Data Sources: Information was obtained through a MEDLINE search (1966–February 2007) and from published abstracts. Search terms included fingolimod, FTY720, FTY-720, and sphlngosine-1-phosphate receptor agonist. Study Selection and Data Extraction: All English-language studies and abstracts pertaining to fingolimod were considered for inclusion. Preference was given to human data. Data Synthesis: Fingolimod Is the first in a new class of immune modulators known as the sphingosine-1-phosphate receptor agonists. It is administered orally once dairy and causes a dose-related reduction in the number ot circulating lymphocytes by preventing their egress from secondary lymph organs, but it does not alter T-cell activation or proliferation. Bradycardia and lymphopenia are the most common adverse effects. Clinical trials have evaluated the efficacy of fingolimod in renal transplantation and multiple sclerosis (MS). Further research for renal transplantation will not take place, but Phase 3 studies in MS are underway, as Phase 2 study results are favorable. Conclusions: Due to its distinct mechanism of action and its oral administration, fingolimod may be a useful therapeutic option for patients with relapsing forms of MS. More data are needed to assess the safety and clinical utility of fingolimod.

OBJECTIVE: To review the pharmacology, efficacy, and safety of efalizumab for the treatment of moderate to severe plaque psoriasis. DATA SOURCES: A MEDLINE search (1966–May 2005%) using the key words hu1124, anti-CD11a, efalizumab, Raptiva, Xanelim, and psoriasis was conducted. References of identified articles were reviewed for additional citations. STUDY SELECTION AND DATA EXTRACTION: Clinical trials evaluating the pharmacology, efficacy, and safety of efalizumab for treatment of moderate to severe plaque psoriasis in adults were included in our review. DATA SYNTHESIS: Efalizumab's ability to inhibit the binding of CD11a, a subunit of leukocyte function–associated antigen type 1, to intracellular adhesion molecule 1 results in decreased T-cell activation and migration, 2 key steps in the immunopathogenesis of psoriasis. Results of clinical trials have demonstrated that efalizumab administered subcutaneously is a safe and effective treatment for moderate to severe plaque psoriasis. Efalizumab was well tolerated in trials, with the majority of adverse events arising with the first dose and decreasing with subsequent doses. The high cost of this agent and lack of head-to-head trials with other drugs will likely restrict its use to patients who have failed prior systemic therapy or phototherapy. CONCLUSIONS: Efalizumab is a safe and effective therapy for treatment of moderate to severe plaque psoriasis in patients who have failed prior systemic therapy or phototherapy.

Objective: To compare desvenlafaxine with its parent drug, venlafaxine, to determine the usefulness of this new medication. Data Sources: Information was obtained through a MEDLINE search (1966-June 2008) and from published abstracts. Search terms included desvenlafaxine, O-desmethyIvenlafaxine, Pristiq, major depressive disorder, and venlafaxine. STUDY selection and data extraction: All English-language studies and abstracts pertaining to desvenlafaxine and venlafaxine were considered for inclusion. Preference was given to human data. Data Synthesis: Desvenlafaxine is a serotonin-norepinephrine reuptake inhibitor and is the active metabolite of the antidepressant venlafaxine. The recommended dose is 50 mg daily, based on the efficacy and safety data of 50, 100,150,200, and 400 mg of desvenlafaxine. The response and remission rates of depression at 8 weeks for the 50-mg dose are 51 -63% and 31-45%, respectively. These rates are comparable with those seen with venlafaxine (58% and 45%, respectively). Adverse effects are also similar to those of venlafaxine, with the most common being insomnia, somnolence, dizziness, and nausea. The decreased potential of CYP2D6 activity with desvenlafaxine compared with the parent drug may be a potential advantage in patients on other medications metabolized via this enzymatic pathway. Also, desvenlafaxine tablets are less expensive than extended-release (XR) venlafaxine, which may decrease healthcare costs in the short term. However, venlafaxine XR is expected to go off patent in 2010. Conclusions: With the overall similarity between these 2 drugs and the potential lack of cost savings, the need for desvenlafaxine and its ultimate utility in treating major depressive disorder appears to be insignificant.

Objective To describe the pharmacology, safety and efficacy, and rationale for use of oral oxymorphone for the management of acute and chronic moderate-to-severe pain. Data Sources A PubMed/MEDLINE search (1966-March 2007) was conducted using the following terms: oral oxymorphone, oxymorphone, EN 3202, EN 3203, Opana, and Opana ER. Manufacturer-provided data (package inserts) and abstracts presented at the American Pain Society meetings (2003–2006) were also reviewed. Study Selection and Data Extraction Human studies evaluating the safety and efficacy of oral oxymorphone in pain management were considered; animal and non–English-language data were excluded. Data Synthesis Oral oxymorphone is a semisynthetic opioid agonist that is specific for the μ-opioid receptor and approved to treat both acute and chronic pain. Unlike other opioids, such as oxycodone, oxymorphone does not bind to the κ-opioid receptor. Due to extensive liver metabolism, oral oxymorphone is contraindicated in patients with moderate-to-severe hepatic impairment; however, no clinically significant CYP3A4, 2C9, or 2D6 mediated drug-drug interactions have been noted. Elderly patients may experience a 40% increase in plasma concentrations, while renally impaired patients may have a 57–65% increase in bioavailability. Food can increase the rate of absorption by as much as 50%, necessitating dosing either 1 hour before or 2 hours after a meal. Oxymorphone's primary adverse effects are similar to those of other opioids: nausea, vomiting, pruritus, pyrexia, and constipation. Conclusions Oxymorphone is an oral therapeutic option approved for the treatment of acute and chronic moderate-to-severe pain. Oxymorphone has a safety and efficacy profile similar to that of other commonly used pure opioids (morphine, oxycodone, hydromorphone). Like oxycodone and morphine, oxymorphone also has immediate-release and extended-re lease formulations. Since cost alone is not yet favorable for oxymorphone over oxycodone or morphine, further studies of comparative efficacy targeting potential advantages of oxymorphone over other opioids are necessary before considering it for addition to a formulary.

OBJECTIVE: To review new pharmacologic agents approved for use in the management of rheumatoid arthritis (RA). DATA SOURCES: A MEDLINE search (1966–January 2000) was conducted to identify English-language literature available on the pharmacotherapy of RA, focusing on celecoxib, leflunomide, etanercept, and infliximab. These articles, relevant abstracts, and data provided by the manufacturers were used to collect pertinent data. STUDY SELECTION: All controlled and uncontrolled trials were reviewed. DATA EXTRACTION: Agents were reviewed with regard to mechanism of action, efficacy, drug interactions, pharmacokinetics, dosing, precautions/contraindications, adverse effects, and cost. DATA SYNTHESIS: Traditional pharmacologic treatments for RA have been limited by toxicity, loss of efficacy, or both. Increasing discoveries into the mechanisms of inflammation in RA have led to the development of new agents in hopes of addressing these limitations. With the development of celecoxib, a selective cyclooxygenase-2 inhibitor, the potential exists to minimize the gastrotoxicity associated with nonsteroidal antiinflammatory drugs. Leflunomide has been shown to be equal to or less efficacious than methotrexate, and may be beneficial as a second-line disease-modifying antirheumatic drug (DMARD). The biologic response modifiers, etanercept and infliximab, are alternatives that have shown benefit alone or in combination with methotrexate. However, they should be reserved for patients who fail to respond to DMARD therapy. Further studies should be conducted to evaluate the long-term safety and efficacy of these agents as well as their role in combination therapy. CONCLUSIONS: Celecoxib, leflunomide, etanercept, and infliximab are the newest agents approved for RA. Clinical trials have shown that these agents are beneficial in the treatment of RA; however, long-term safety and efficacy data are lacking.

OBJECTIVE: To familiarize readers with a potentially new class of compounds for treating asthma. Background information on leukotrienes is provided in addition to an indepth review of pertinent clinical trials. DATA SOURCES: Information was obtained from controlled clinical trials, abstracts, and review articles identified through a MEDLINE search of English-language articles. STUDY SELECTION: Emphasis was placed on early clinical trials that showed some benefit with these compounds as well as more recent studies using newer agents that produced more promising results. DATA EXTRACTION: Information regarding leukotriene biochemistry was extracted from basic science research and data from human studies were evaluated by the authors according to patient selection, study design, methodology, and therapeutic response. DATA SYNTHESIS: Leukotrienes have a pathophysiologic role in asthma. Two distinct but pharmacologically similar classes of leukotriene inhibitors are currently being clinically evaluated. These are leukotriene receptor antagonists and 5-lipoxygenase inhibitors. Early clinical trials with these agents yielded unfavorable results primarily because of lack of drug potency and selectivity, poor patient tolerance, and possibly the route of administration. Subsequent studies with more potent and selective agents have further implicated leukotrienes as biochemical mediators in asthma and, consequently, have shown promising clinical outcomes with respect to pulmonary function testing and patient tolerance. CONCLUSIONS: Advancements in the pathogenesis of asthma are beginning to define a role for the leukotrienes. Although more studies are needed to assess the efficacy of leukotriene inhibitors, recent clinical trials using leukotriene-receptor antagonists and 5-lipoxygenase inhibitors indicate a potential for the expansion of therapeutic regimens currently used in the treatment of asthma.

OBJECTIVE: To review the literature and provide recommendations for the development and dissemination of written medication information to patients and their care providers. DATA SOURCES: A MEDLINE search (1966–1997) of the English-language literature was performed to identify articles pertaining to the development or use of written medication information. A search of the Internet was conducted by using Yahoo as the guide and “medication information” as the search term. Additional resources were obtained through texts, bibliographies, and catalogs from medical publishers. DATA EXTRACTION: Reports documenting the creation and use of written medication information systems were reviewed, as well as studies of readability and reading skills assessment. Examples of materials available for purchase by laypeople and healthcare providers were also examined. DATA SYNTHESIS: Current statistics support the widespread availability of written medication information for patients and care providers. The goal set forth by the Food and Drug Administration of having 75% of patients receive written information by the year 2000 appears achievable. However, there are still many issues to address. Content is not standardized, and materials are frequently written at reading levels higher than that of the average patient. The development and use of resources requiring only minimal reading skills and an increase in the availability of materials written in Spanish are needed. CONCLUSIONS: Written medication information provides a useful addition to counseling by healthcare professionals. A wide variety of prepared materials is available, as well as resources for those interested in developing tools for a specific patient, population, or setting. Healthcare professionals should be aware of the limitations of some resources. Content and readability must be appropriate for the intended audience for these tools to serve a useful role in patient education.

Abstract Objectives.—To review the literature for conditions, diseases, and disorders that affect activity of the contact factors, and further to review the literature for evidence that less than normal activity of any of the contact factors may be associated with thrombophilia. Data Sources.—MEDLINE search for English-language articles published from 1988 to 2001 and pertinent references contained therein, as well as search of references in recent relevant articles and reviews. Study Selection.—Relevant clinical and laboratory information was extracted from selected articles. Meta-analysis was not feasible because of heterogeneity of reports. Data Extraction and Synthesis.—Evidence for association of altered levels of the contact factors and thrombophilia was sought. A wide variety of disorders is associated with decreased activity of the contact factors; chief among these disorders are liver disease, hepatic immaturity of newborns, the antiphospholipid syndrome, and, for factor XII, being of Asian descent. These disorders are more common than homozygous deficiency. The few series and case reports of thrombophilic events in patients homozygous for deficiency of contact factors are not persuasive enough to support causality. The apparent association between levels consistent with heterozygosity (40%–60% of normal) of any of the contact factors (but especially factor XII) in persons with antiphospholipid antibodies appears to be due to falsely decreased in vitro activity levels of these factors, which are normal on antigenic testing. The apparent association with thrombosis is better explained by the antiphospholipid syndrome than by the modest reduction of the levels of contact factors. Conclusions.—Presently, it is not recommended to measure activity of contact factors during routine evaluation of patients who have suffered venous or arterial thromboembolism or acute coronary syndromes.

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.
