Objective: To review the pharmacology, pharmacokinetics, clinical trial data, and safety profile of tocilizumab, a new biologic agent targeting the lnterleukin-6 cytokine receptor. Data Sources: A systematic search of MEDLINE (1998–June 2008) and International Pharmaceutical Abstracts (1970–June 2008) was performed to identify published clinical trials and review articles. Key search terms were tocilizumab, MRA, interleukin-6/receptors, interleukln-6/immunology, and rheumatoid arthritis. The search was limited to studies in humans that were published in the English language. References from articles located during this search were evaluated for other relevant citations. Abstracts from national and international rheumatology meetings (American College of Rheumatology and European League Against Rheumatism) and from unpublished Phase 3 clinical trials in progress (using www.clinicaltrials.gov ) were also reviewed. Study Selection and Data Extraction: All available human studies describing the pharmacology, pharmacokinetics, efficacy, safety, and adverse effects of tocilizumab were included. Data Synthesis: At doses greater than 4 mg/kg, tocilizumab use has resulted In significant improvement in clinical outcomes, including the American College of Rheumatology parameters indicating a patient's level of improvements and disease remission. Improvements were noted when tocilizumab was used as monotherapy or in combination with methotrexate or other disease-modifying antirheumatic drugs. The most effective dose of tocilizumab appears to be 8 mg/kg, which has shown significant improvements in radiographic measures of joint damage. The most common adverse effects have included abnormal results of liver function tests, hyperlipidemia, neutropenia, infections, nasopharyngitis, gastrointestinal complaints, musculoskeletal disorders, headache, rash, and pruritus. Conclusions: Tocilizumab represents a promising new treatment for rheumatoid arthritis. Additional research is warranted to confirm its radiographic benefits, clarify its safely profile, and identify its place in rheumatoid arthritis treatment relative to current biologic agents.

Objective: To review the pharmacology, pharmacokinetics, clinical efficacy, and adverse effects of granisetron, focusing on critical analysis of published clinical trials and comparison with other antiemetic agents, including ondansetron. Data Sources: MEDLINE (1966–1995) and CANCERLIT (1991–1995) searches of English-language literature using the terms “granisetron” and “granisetron (m)” were performed. Study Selection And Data Extraction: All articles were considered for possible inclusion in this review. Abstracts of clinical trials were included only when they were judged to add critical information not otherwise available in the medical literature. For studies published more than once, the most recent publication was cited. Data Synthesis: Nausea and vomiting are rated by patients as the most distressing chemotherapy-related adverse effects and may produce potentially life-threatening complications. The discovery of the role of serotonin in nausea and vomiting and the development of selective serotonin3-receptor (5-HT3) antagonists has significantly diminished the incidence and consequences of chemotherapy-related nausea and vomiting. Granisetron is the second 5-HT3-receptor antagonist to be marketed in the US. Granisetron has been compared with other antiemetic agents, including ondansetron, against highly and moderately emetogenic chemotherapy. The results of these trials have shown granisetron to be superior to conventional antiemetics and as effective as ondansetron in the prevention of chemotherapy-induced nausea and vomiting. The optimal dose of granisetron has yet to be determined. Formulary decisions should be based on a cost comparison among the 5-HT3-receptor antagonists at individual institutions. Conclusions: Granisetron is a safe, effective antiemetic agent for the management of nausea and vomiting caused by cancer chemotherapy.

Objective: The purpose of this article is to review the available clinical trial data that led to the Food and Drug Administration (FDA) approval of solriamfetol as well as its role in clinical practice. Data Sources: A MEDLINE/PubMed search was conducted (January 2000 to February 2020) using the keyword solriamfetol to discover appropriate clinical trials. Study Selection and Data Extraction: Articles were included that were published in the English language and related to the FDA approval of solriamfetol or provided novel information regarding this drug entity. Data Synthesis: The findings of the review show that solriamfetol may be a safe and effective option for the treatment of excessive sleepiness (ES) related to narcolepsy and obstructive sleep apnea (OSA). Relevance to Patient Care and Clinical Practice: Solriamfetol is distinguished from other stimulants in that it has lower binding affinity to dopamine and norepinephrine transporters and does not have the monoamine-releasing effects of amphetamines at usual therapeutic doses. Because of solriamfetol’s unique mechanism of action, there may be a reduction in abuse potential compared with the other currently FDA-approved options. Conclusions: In clinical trials, solriamfetol has shown dose-dependent improvement in wakefulness over placebo and adds another option for clinicians when treating ES in narcolepsy and OSA.

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.

OBJECTIVE: To review the use of transdermal fentanyl for the treatment of moderate to severe chronic pain. The article provides background on the pharmacology and pharmacokinetics of the drug, as well as the properties of the transdermal system. In addition, clinical trials, adverse effects, and therapeutic considerations and recommendations are presented. DATA SOURCES: Clinical trials, review articles, and reference texts. STUDY SELECTION: Comparative clinical trials involving the use of transdermal fentanyl on postoperative and chronic pain patients. DATA EXTRACTION: Data from clinical human trials published in the English language were reviewed. Trials were assessed by sample size, opioid dosage regimen, and therapeutic outcome. DATA SYNTHESIS: Transdermal fentanyl was found to be effective in the control of chronic and postoperative pain. In one trial the overall patient satisfaction with pain control was 79 percent for the transdermal fentanyl group and 44 percent for the placebo group. In another trial, the amount of additional parenteral morphine was significantly lower for the group receiving transdermal fentanyl than for the placebo group (49.9 ± 4.9 vs. 77.0 ± 6.3 mg, respectively, p<0.01). The most common adverse effects recorded were nausea (45–85 percent), pruritus (14–60 percent), and sedation (40–59 percent). The cost of analgesic therapy with this delivery system is higher than that of parenteral opioid analgesia, but less than patient-controlled analgesia. CONCLUSIONS: The transdermal fentanyl formulation offers some minor advantages over other forms of conventional pain management. Results of early clinical trials are promising, but more studies are needed to evaluate its long-term effectiveness and adverse effects. Specifically, comparisons with standard parenteral and patient-controlled opioid analgesia in chronic malignant and nonmalignant pain are necessary for adequate evaluation of transdermal fentanyl.

Objective: To provide a concise review of the new Food and Drug Administration (FDA)-approved antipsychotic, lumateperone, for use in schizophrenia. Data Sources: A literature search of PubMed was performed (January 2000 to May 2020) using the following key terms: lumateperone, Caplyta, and ITI-007. Abstracts from conferences, review articles, clinical trials, and drug monographs were reviewed. Study Selection and Data Extraction: Relevant English-language monographs and studies conducted in humans were considered. Data Synthesis: Lumateperone was FDA approved for the treatment of schizophrenia in December 2019 based on 2 published randomized, double-blind, placebo-controlled trials. Lumateperone’s pharmacology is consistent with that of other second-generation antipsychotics in that it has a higher affinity for the serotonin (5-HT2A) receptors compared with dopamine (D2) receptors but with lower affinities for α-1 and histaminergic receptors. In addition, it serves as a presynaptic dopamine partial agonist, serotonin reuptake inhibitor, and an indirect modulator of glutamatergic systems. Based on the 4-week clinical trials, lumateperone was well tolerated. Most common treatment-emergent adverse events were headache, somnolence, and dizziness. Relevance to Patient Care and Clinical Practice: At this time, lumateperone had a statistically significant reduction in Positive and Negative Syndrome Scale when compared with placebo and was not significantly associated with the extrapyramidal symptoms (EPS) and metabolic adverse effects commonly seen with other antipsychotics. Conclusions: Lumateperone has the potential to benefit individuals with schizophrenia who are intolerant to the EPSs or metabolic adverse effects of other antipsychotics. However, further head-to-head trials with commercially available antipsychotics are still required to assist in establishing its role in treatment.

The use of methotrexate in rheumatoid arthritis is reviewed. Methotrexate, a folic acid antagonist, is sometimes employed in an attempt to symptomatically control patients whose disease does not respond adequately to conventional therapies. Systemic administration of 7.5–15 mg/wk in a “pulse” fashion appears to be effective without precipitating severe adverse effects. However, concern over potentially serious side effects and a lack of well-controlled clinical trials have limited its use to severe, refractory disease. Further studies are needed before its role in rheumatoid arthritis can justifiably be expanded.

Objectives: To review the pharmacology, efficacy, and safety of Brexanolone and define its role in the treatment of postpartum depression. Date Sources: A MEDLINE/PubMed search was conducted (1980-May 2020) using the following keywords: postpartum depression, antidepressants, pharmacologic therapy, drug therapy, and brexanolone to identify relevant articles. Study Selection/Data Extraction: Literature search was limited to human studies published in the English language. Phase I, II, and III studies evaluating the pharmacology, efficacy, safety of brexanolone for postpartum depression were included. Bibliographies of relevant articles evaluating postpartum depression and treatment were reviewed for additional citations and background information. Data Synthesis: Brexanolone is a soluble, proprietary, injectable formulation of allopregnanolone, a neuroactive steroid that modulates neuronal excitability. Allopregnanolone levels increase during pregnancy and decrease substantially after birth. These fluctuations have profound effects on anxiety and depression. Three clinical trials established the efficacy and safety of brexanolone in the treatment of postpartum depression. In all 3 trials, brexanolone had an acceptable safety profile and was well tolerated. The most common adverse effects were loss of consciousness, sedation, dry mouth, headache, dizziness, and flushing. Due to sudden loss of consciousness and excessive sedation, continuous pulse oximetry is recommended. Conclusion: Brexanolone has a novel mechanism of action and appears to be safe and effective for the treatment of moderate to severe postpartum depression. At present, high cost, serious adverse effects, and restricted access may limit its use in clinical practice.

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 pharmacology, pharmacokinetics, clinical efficacy, and toxicity of ticlopidine. Comparisons with other antiplatelet agents are presented, with an emphasis on efficacy, and a recommendation is provided regarding ticlopidine's place in therapy. DATA SOURCES: A MEDLINE literature retrieval of English-language journal articles from 1987 to January 1993 and references identified from bibliographies of review articles and clinical trials. STUDY SELECTION: Randomized, blind, controlled studies of ticlopidine and other antiplatelet agents were preferentially selected. DATA EXTRACTION: Clinical trials were reviewed in terms of study design, efficacy results, and toxicity. DATA SYNTHESIS: Ticlopidine is a new antiplatelet agent with a distinct mechanism of action. In the largest trial of the drug for the prevention of stroke, it was found to be more effective than aspirin in reducing the risk of stroke or death. Clinical trials have also shown ticlopidine to decrease the rate of vascular death and myocardial infarction in patients with unstable angina, and to maintain venous graft patency after coronary artery bypass grafting. The use of ticlopidine in diabetic microangiopathy and peripheral vascular disease appears promising, but further studies are needed. Adverse reactions most commonly reported with ticlopidine are gastrointestinal complaints; the most severe reaction is transient neutropenia, which is seen in approximately 2.3 percent of patients and is severe in nearly 1 percent. CONCLUSIONS: Ticlopidine is a reasonable alternative for use in preventing stroke among patients unable to take aspirin or those who do not benefit from aspirin therapy. Its use as first-line therapy is limited by its high cost and the occurrence of hematologic adverse effects.
