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.

Introduction: Till date, no proven therapy exists for coronavirus disease (COVID-19), though different types of treatment modalities are being practiced around the world. Different studies regarding convalescent plasma (CP) therapy from COVID-19 recovered donors have shown favorable results with fewer adverse consequences. In this systematic review, we have aimed to determine the safety and efficacy of CP as a therapy for COVID-19. Methods and Materials: The English language databases of PubMed, Google Scholar, and ScienceDirect were searched up to 22 May 2020. Eligibility for inclusion, risk of bias assessment, and data extraction from the included studies were determined and a narrative synthesis was conducted. Results: A total of 12 studies were selected for review. The overall risks of bias were moderate to high. The results revealed significance in the initiation of CP therapy during the early stages of viremia in a safety and efficacy viewpoint. The patients were also receiving concomitant drugs and other supportive therapies in most cases. Some cases of mortality were reported in 3 studies. Viral loads were documented to decrease and become negative in 8 studies within 3-26 days post-transfusion. The improvement in clinical symptoms following CP therapy was demonstrated in 9 studies. Most of the patients experienced very few adverse effects. Conclusions: The rational practice of CP therapy based on a risk-benefit judgment can prove to be an efficacious therapeutic option as a last resort until the approval of any therapeutic and/or prophylactic agent(s). The substantial randomized controlled trials (RCTs) are necessary to validate the effectiveness of such therapy.

Stereoselective Pharmacokinetics

OBJECTIVE: To review the previously published studies on pharmacokinetics and pharmacodynamics of chiral drugs used in the treatment of asthma. DATA SOURCES: Primary and review articles were identified with a MEDLINE search (1980–May 2001) and through secondary sources. STUDY SELECTION AND DATA EXTRACTION: All English-language studies and reviews obtained from the MEDLINE search pertaining to stereoselective pharmacokinetics and pharmacodynamics of chiral anti-asthma drugs were assessed. DATA SYNTHESIS: Several anti-asthma drugs (e.g., β2-adrenergic agonists, leukotriene modifiers) are chiral and marketed as racemates, which consist of equal proportions of 2 enantiomers. Significant stereoselectivity has also been reported in pharmacodynamics and pharmacokinetics of the β2-agonists. The enantiomers of β2-agonists in the R configuration are primarily responsible for the bronchodilating effects of the racemate. The plasma concentrations of the enantiomers of anti-asthma drugs may differ as a reflection of stereoselectivity in clearance, volume of distribution, and route of administration. CONCLUSIONS: Stereoselectivity in the pharmacokinetics of anti-asthma drugs may complicate the relationship between dose and/or plasma concentration of racemic drug versus effect relationship. An appreciation of the stereoselective pharmacokinetics and pharmacodynamics of chiral anti-asthma drugs may optimize the use of these agents in asthmatic patients.

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 provide a comprehensive review of the pharmacokinetic and pharmacodynamic interactions between antipsychotics and antihypertensives and to provide recommendations for the selection of antihypertensives in patients receiving antipsychotic therapy. Data Sources: A MEDLINE search of the English-language literature was used to identify pertinent human and animal studies, reviews, and case reports. Study Selection: All available sources were reviewed. Data Extraction: Background information was obtained from comprehensive reviews. Individual case reports were assimilated, and pertinent data were extracted. Data Synthesis: Because hypertension is common in patients with psychiatric illness and antihypertensive agents are used for a multiplicity of indications, significant numbers of patients receive concurrent therapy with antihypertensives and antipsychotics. Many antipsychotics may block the antihypertensive efficacy of guanethidine and related drugs. The interaction between Clonidine and antipsychotics is defined less clearly. Limited data suggest possible additive hypotensive effects when chlorpromazine and methyldopa are given in combination. Increased plasma concentrations of thioridazine with a resultant increase in adverse effects have been reported when propranolol or pindolol are added to the regimen. A similar increase in chlorpromazine concentrations has been reported when propranolol was added. Although there are no reports documenting an interaction between a calcium-channel antagonist and an antipsychotic, the possible inhibition of oxidative metabolism of antipsychotics, additive calcium-blocking activity, and additive pharmacodynamic effects are theorized. Hypotension and postural syncope were reported in a patient given therapeutic dosages of chlorpromazine and Captopril, and in 2 patients when clozapine was added to enalapril therapy. Conclusions: No antipsychotic-antihypertensive combination is absolutely contraindicated, but no combination should be considered to be completely without risk. Antihypertensives with no centrally acting activity, such as diuretics, may be the least likely to result in adverse reactions. The combination of the beta-antagonists propranolol or pindolol with thioridazine or chlorpromazine should be avoided if possible. Scrupulous patient monitoring for attenuated or enhanced activity of either agent is essential whenever antipsychotics and antihypertensives are given concurrently.

Leukotriene Receptor

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 report a case in which propofol was used successfully in an intubated patient on a prolonged basis and to review the literature that discusses long-term infusions (> 7 days) of propofol. METHODS: Information was retrieved from a MEDLINE search of the English-language literature. Reports of clinical trials and case reports that compared the safety and efficacy of long-term propofol and midazolam were included in this review. Information about the study design and the efficacy and adverse effects of the drugs was collected, and the data were synthesized. RESULTS: Clinical reports indicate that a long-term infusion of propofol is comparable in safety and efficacy to a long-term infusion of midazolam. The distinct adverse-effect profile of long-term use of propofol, including hypertriglyceridemia, was evaluated and reported as significant. CONCLUSION: The limited data available suggest that long-term infusion of propofol is a practical alternative to use of standard agents for sedation of intubated patients. Adverse effects such as cardiovascular depression, respiratory depression, and hypertriglyceridemia may limit the routine use of propofol.

Objective To describe a case of isoniazid-associated psychosis and review the incidence of this adverse effect. Data Sources Information about the patient was obtained from the medical chart. A MEDLINE search of the English-language literature published from 1950 to 1992 was conducted and Index Medicus was manually searched for current information. Study Selection All case reports describing isoniazid-associated psychosis were reviewed. Data Extraction Studies were evaluated for the use of isoniazid, symptoms of psychosis, onset of symptoms, and dosage of isoniazid. Data Synthesis The case report is compared with others reported in the literature. The incidence of isoniazid-associated psychosis is rare. Conclusions The mechanism of isoniazid-associated psychosis is uncertain. It appears that isoniazid was associated with the psychosis evident in our patient and in the cases reviewed.
