Treatment of nicotine dependence with bupropion SR: review of its efficacy, safety and pharmacological profile

ADDICTION BIOLOGY, Issue 1 2003
JOSÉ MARTÍNEZ-RAGA
Bupropion hydrochloride, an atypical antidepressant, is the first non-nicotine product that, in its sustained release form (bupropion SR), has been licensed as an aid for smoking cessation. The specialized literature on bupropion SR and smoking cessation is critically reviewed. The pharmacological profile, dosage and administration, contraindications, as well as the clinical efficacy, safety and tolerability data of bupropion are discussed. Recent reports suggest that its mode of actions might be different to what had originally been proposed. When prescribed appropriately, it appears to be a safe, well-tolerated and effective medication in combination with smoking cessation counselling,for a wide range of smokers, as shown in several multicentre double-blind, placebo-controlled clinical trials. Further research is needed on aspects such as the optimal duration of treatment, the potential role of combination therapy with NRT and psychological interventions, and to establish its effectiveness in smokers with other psychiatric disorders or when used with only minimal support by general practitioners.

The management of severe emergence agitation using droperidol

ANAESTHESIA, Issue 11 2006
R. Hatzakorzian
Summary Emergence agitation can occur following recovery from general anaesthesia. The patient may exhibit aggressive behaviour, disorientation, agitation and restlessness. Untreated, this complication may result in significant morbidity. We report two cases where droperidol was successfully used in the management of severe emergence agitation. In the first case, droperidol was administered to prevent the occurrence of postoperative agitation in a patient known to suffer from this condition following previous general anaesthetics. In the second case, droperidol was used to treat emergence agitation in a morbidly obese patient with a difficult airway who was aggressive and difficult to restrain. Both of these patients remained calm and co-operative, with stable cardio-respiratory parameters, following the administration of droperidol and showed no further signs of agitation. We suggest that droperidol is an effective medication that may be used to prevent and treat severe emergence agitation due to its rapid sedative effect and minimal cardio-respiratory depression.

Thalidomide dramatically improves the symptoms of early-onset Sarcoidosis/Blau syndrome: Its possible action and mechanism

ARTHRITIS & RHEUMATISM, Issue 1 2010
Kozo Yasui
Objective Early-onset sarcoidosis (EOS), which occurs in children younger than 5 years of age, is associated with granulomatous lesions and a sporadic genetic mutation of the nucleotide-binding oligomerization domain 2 that causes constitutive NF-,B activation. The symptoms of EOS can be uncontrollable, progressive, and associated with profound complications. However, appropriate therapy is still under investigation. The aim of this study was to assess the efficacy of thalidomide in patients with severe EOS, based on etiology supporting an initial role of NF-,B in activation of this disease. Methods Thalidomide was given to 2 patients with EOS (a 16-year-old girl and an 8-year-old boy) at an initial dosage of 2 mg/kg/day, and the dosage was increased if necessary. To elucidate the mechanism of the drug, peripheral blood monocytes were isolated from the patients and stimulated with cytokines (macrophage colony-stimulating factor, tumor necrosis factor ,, and interleukin-4), and their ability to form multinucleated giant cells (MGCs) and osteoclasts was measured. Results Both patients showed dramatic improvement of their clinical symptoms (alleviation of fever and optic nerve papillitis, achievement of a response according to the American College of Rheumatology Pediatric 50 and Pediatric 70 criteria) and laboratory findings. Monocytes from patients with EOS had a greater ability to survive and induce MGCs and osteoclasts than those from healthy control subjects. The formation of MGCs and osteoclasts was inhibited by the presence of thalidomide. Conclusion The ability of thalidomide to improve clinical symptoms and laboratory findings in patients with EOS indicates a central role for NF-,B activity in this disorder. Inhibition of IKK might be a pharmacologic action by which thalidomide down-regulates NF-,B signaling. Thalidomide may be an effective medication in patients with severe complications of EOS, including ocular involvement. [source]


The man with the purple nostrils: a case of rhinotrichotillomania secondary to body dysmorphic disorder

ACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2002
L. F. Fontenelle
Objective: To describe a different type of self-injurious behavior that may be secondary to body dysmorphic disorder (BDD). Method: Single case report. Results: We reported a case of an individual who have developed the self-destructive habit of pulling and severely scraping hairs and debris out of the mucous membrane of his nasal cavities. We have proposed the term rhinotrichotillomania to emphasize the phenomenological overlapping between trichotillomania (TTM) and rhinotillexomania (RTM) exhibited by this case. The main motivation behind the patient's actions was a distressing preoccupation with an imaginary defect in his appearance, which constitutes the core characteristic of BDD. The patient was successfully treated with imipramine. Conclusion: The case suggests that certain features of TTM, RTM, and BDD may overlap and produce serious clinical consequences. Patients with this condition may benefit from a trial of tricyclics when other effective medications, such as serotonin reuptake inhibitors, are not available for use. [source]


Cocaine Rapid Efficacy Screening Trial (CREST): a paradigm for the controlled evaluation of candidate medications for cocaine dependence

ADDICTION, Issue 2005
Deborah B. Leiderman
ABSTRACT Aim Development of effective medications for the treatment of cocaine dependence remains a major priority for the National Institute on Drug Abuse (NIDA) at the National Institutes of Health. The Cocaine Rapid Efficacy Screening Trial (CREST) paradigm was developed by the Division of Treatment Research and Development (DT R&D) at NIDA with the goal of enhancing pilot clinical trial validity when systematically assessing a range of medications and drug classes for potential utility in treatment of cocaine dependence. Design CREST utilizes a randomized, controlled, parallel group, blinded methodology for comparing one or more marketed medications against a standard, pharmaceutical grade placebo. The trial design is comprised of a flexible 2,4-week screening/baseline period followed by randomization to an 8-week treatment period. Measures Standard measures of outcomes for the CREST included urinary benzoylecgonine (primary metabolite of cocaine), retention, cocaine craving, depression, clinical global impression and HIV-risk behaviors. In order to facilitate comparisons of data from the CREST studies across sites, drug classes and time, standardized procedures, measures and psychosocial counseling were used. Results A total of 19 medications were evaluated in out-patient treatment research clinics in Boston, Cincinnati, Los Angeles, New York and Philadelphia. Conclusions Findings supported decisions to move forward three medications (cabergoline, reserpine, tiagabine) using full-scale, adequately powered, randomized placebo-controlled trial designs. Lessons learned from the CREST experience continue to shape cocaine pharmacotherapy trial design and execution. [source]


CLINICAL STUDY: Predicting the effect of naltrexone and acamprosate in alcohol-dependent patients using genetic indicators

ADDICTION BIOLOGY, Issue 3 2009
Wendy Ooteman
ABSTRACT Acamprosate and naltrexone are effective medications in the treatment of alcoholism. However, effect sizes are modest. Pharmacogenomics may improve patient-treatment-matching and effect sizes. It is hypothesized that naltrexone exerts its effect through genetic characteristics associated with the dopaminergic/opioidergic positive reinforcement system, whereas acamprosate works through the glutamatergic/GABAergic negative reinforcement system. Alcohol-dependent subjects were randomly assigned to either acamprosate or naltrexone. Subjects participated in a cue-exposure experiment at the day before and at the last day of medication. Reductions in cue-induced craving and physiological cue reactivity were measured. Differential effects of naltrexone and acamprosate on these outcomes were tested for different polymorphisms of the opioid, dopamine, glutamate and GABA-receptors. Significant matching effects were found for polymorphisms at the DRD2, GABRA6 and GABRB2 gene. In addition, a trend was found for the OPRM1 polymorphism. This provides evidence for the matching potential of genotypes. It is expected that more effective treatments can be offered when genetic information is used in patient-treatment-matching. [source]


Can experimental paradigms and animal models be used to discover clinically effective medications for alcoholism?

ADDICTION BIOLOGY, Issue 4 2005
Mark Egli
Evaluating medications in animal laboratory paradigms can reveal whether the compound is effective in an established alcoholism model, at clinically relevant doses and exposure conditions, when administered orally (or transdermally) and without serious limiting side effects. Positive outcomes constitute a possible discovery for relevance to alcoholism and, under favorable marketing conditions, encourage further development. Medication testing using animal models of alcoholism might also guide clinical testing by discriminating clinically effective from clinically ineffective compounds. This ability rests on whether there are tests or, more reasonably, batteries of tests having this discriminative ability. The present paper examines this possibility. Effects of naltrexone and acamprosate in animal paradigms which model behavioral aspects of alcoholism are reviewed and compared with the effects of compounds which have limited effects in alcoholics. It is not clear at present whether any single paradigm or combination of paradigms differentiates clinically effective from clinically limited compounds. Steps are suggested to improve the use of preclinical laboratory tests to predict which compounds are likely to be effective medications for reducing drinking and sustaining abstinence in human alcoholics.

Sticky issue of adherence

JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 1 2003
SM Sawyer
Abstract: The phenomenon of adherence, also known as compliance, is the vital link that allows effective medications to have the desired clinical effect when self-administered. It is often assumed that the population is generally adherent, but more than 50% of people with chronic illness do not take their medication as prescribed. We highlight how the terminology and language of non-adherence act to conceptualize adherence as a patient problem in a manner that is inadvertently judgmental, narrowly focused and clinically unhelpful. In contrast, knowledge of the dynamic nature of adherence promotes the conceptualization of adherence as the common problem that it is, where the responsibility for improving it lies primarily with the health professional. The example of asthma is used to highlight how individually focused clinical strategies can fit within a population perspective that, in its entirety, can be conceptualized as a framework of adherence-promoting strategies.

Adherence to Oral Therapy for Type 2 Diabetes: Opportunities for Enhancing Glycemic Control

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 1 2004
CDEArticle first published online: 24 MAY 200, David Bartels PharmD
Purpose Although diet and exercise are important parts of type 2 diabetes treatment, most patients require pharmacological intervention with multiple agents to maintain adequate glycemic control. This article addresses the numerous patient-related, disease-related, and demographic variables affecting medication adherence in this patient population. Data Sources Extensive review of scientific literature, clinical practice guidelines, and Internet sources. Conclusions Studies have demonstrated that treatments including multiple medications or frequent dosing had a negative impact on adherence. Practitioners have used several approaches in an effort to improve adherence to oral antidiabetic medical therapy, including increased communication between health care providers and patients, implementation of multidisciplinary programs, and use of treatment regimens with easier dosing (i.e., reduced number of drugs or doses taken per day). Implications for Practice Options for type 2 diabetes treatments that combine effective medications into a simpler oral-dosage form may motivate and improve patient adherence. Ultimately, simplifying dosing may lead to better glycemic control, thereby reducing the risks associated with long-term consequences of the disease. [source]


Review article: practical management of inflammatory bowel disease patients taking immunomodulators

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 1 2005
C. A. SIEGEL
Summary Azathioprine, mercaptopurine, methotrexate, ciclosporin and tacrolimus all have their respective niches in the treatment of inflammatory bowel disease. These immunomodulators are potent and effective medications; however, they potentially have serious toxicity. To maximize benefit and minimize risk, clinicians must understand the mechanism of action, appropriate indications, range of toxicity and proper dosing of these medications. Furthermore, once initiating therapy, patients need to be monitored appropriately for evidence of efficacy and toxicity. This review includes the rationale behind recommendations for the management and monitoring of patients using immunomodulators. For the purine antagonists , azathioprine and mercaptopurine , the evidence for utility of thiopurine methyltransferase testing and mercaptopurine metabolite monitoring is addressed. The roles of liver biopsy and screening for methylenetetrahydrofolate reductase mutations in patients taking methotrexate are reviewed. With appropriate monitoring, the calcineurin inhibitors , ciclosporin and tacrolimus , can be used safely and effectively. Immunomodulators are important agents for the treatment of Crohn's disease and ulcerative colitis, and prescribing clinicians should be comfortable recognizing both their value and their limitations.
