Final Original Report Drug Effectiveness Review Project STRUCTURED ABSTRACT Purpose We compared the effectiveness and harms of tricyclic antidepressants, serotonin norepinephrine reuptake inhibitors, selective serotonin reuptake inhibitors, selective serotonin and norepinephrine reuptake inhibitors, noradrenergic and specific serotonergic reuptake inhibitor, norepinephrine and dopamine reuptake inhibitor, serotonin receptor antagonist, antiepileptic drugs, and skeletal muscle relaxants in adults with fibromyalgia. Data Sources We searched Ovid MEDLINE , the Cochrane Database of Systematic Reviews , and the Cochrane Central Register of Controlled Trials and Database of Abstracts of Reviews of Effects through October 2010. For additional data we also hand searched reference lists, US Food and Drug Administration medical and statistical reviews and dossiers submitted by pharmaceutical companies. Review Methods Study selection, data abstraction, validity assessment, grading the strength of the evidence, and data synthesis were all carried out according to standard Drug Effectiveness Review Project review methods. Results and Conclusions We found eligible studies of treatment for fibromyalgia with amitriptyline, nortriptyline, citalopram, fluoxetine, paroxetine, cyclobenzaprine, pregabalin, gabapentin, milnacipran, and duloxetine. We found no eligible studies with the other included drugs and no eligible studies of included interventions when used as adjunctive therapy. Head-to-head trials were few, and provided low-strength evidence that short-term treatment with immediate-release paroxetine is superior to amitriptyline in reducing pain and sleep disturbance and provided low-strength evidence there are no significant differences between amitriptyline as compared with cyclobenzaprine and nortriptyline. Although there were some significant differences between drugs in overall adverse events, they did not produce any differences in withdrawals due to adverse events. Additionally, based on indirect comparison meta-analysis, we found low evidence that duloxetine was superior to milnacipran on outcomes of pain, sleep disturbance, depressed mood, and health-related quality of life. We found low evidence that both duloxetine and milnacipran were superior to pregabalin on improvement in depressed mood, whereas pregabalin was superior to milnacipran on improvement in sleep disturbance. Amitriptyline was similar to duloxetine, milnacipran, and pregabalin on outcomes of pain and fatigue, with insufficient data on the other outcomes. Although there were some significant differences between duloxetine, milnacipran, and pregabalin in specific adverse events, they did not produce any differences in overall withdrawals, overall adverse events, and withdrawals due to adverse events. For the remaining drugs, there was only evidence of significant improvements in pain over placebo in 1 trial for gabapentin, in 1 of 3 trials for cyclobenzaprine, and in 1 trial of Drugs for fibromyalgia 2 of 86 Final Original Report Drug Effectiveness Review Project fluoxetine. But, no conclusions can be drawn about comparative effectiveness or harms among these drugs because the numbers of trials/patients in placebo-controlled trials were too few to provide meaningful results in indirect comparisons. Duloxetine was not effective on pain reduction in male, nonwhite, and older patients based on a small sample size that was underpowered to detect a difference. Compared with placebo, duloxetine, fluoxetine, controlled- release paroxetine, and pregabalin significantly improved fibromyalgia symptoms regardless of baseline depression but milnacipran was only effective in nondepressed patients. Controlled- release paroxetine and pregabalin significantly improved fibromyalgia symptoms regardless of baseline anxiety.

The American College of Rheumatology first issued criteria for diagnosing fibromyalgia in 1990, which included widespread pain, defined as axial, bilateral, and both upper and lower segment pain, duration of greater than 3 months, and the presence of ≥ 11 out of 18 tender points (see Appendix A). Prior to this time, terms such as fibrositis and functional somatic syndrome were used with varying criteria including presence of additional symptoms such as depression, sleep disorder, and fatigue, symptoms that are often seen in patients with fibromyalgia but not considered diagnostic. Much controversy has existed over the past 2 decades regarding the validity of fibromyalgia as a clinical entity as well as the validity of the diagnostic criteria used to identify individuals with the disorder. In May 2010, the American College of Rheumatology published their new criteria for diagnosing fibromyalgia, eliminating 2 the requirement of tender points and expanding it to include 3 conditions: 1. Widespread pain index ≥ 7 and symptom severity scale score ≥ 5 or widespread pain index 3-6 and symptom severity scale score ≥ 9 2.

Recently buy generic tizanidine 2mg on line, the FDA and EMA have granted marketing approval to two fixed-dose combinations tizanidine 2 mg sale. Evotaz is a combination of atazanavir and cobicistat buy discount tizanidine 2 mg on-line, Prezcobix or Rezolsta contains cobicistat and darunavir order 2mg tizanidine with mastercard. Saquinavir and fosamprenavir do not play an important role, nelfinavir and amprenavir have been taken from the market. Tipranavir is only used in specific salvage settings. Resistance on boosted PIs is significantly less than with NNRTIs or integrase inhibitors; PI/r resistance hardly exists (Gupta 2008). The slightly higher pill burden and frequent gastrointestinal side effects, which complicate adherence, are disadvantages of a PI-containing therapy. Often small factors are important when choosing the right PI, see Table 6. Issues which may have an impact on treatment decision DRV/r/c LPV/r ATV/r/c SQV/r FPV/r Pill number/day 1–2 4 1–2 6 4 Once daily dosing? Irrelevant Irrelevant yes yes Irrelevant Important side effects Diarrhea (mild) DiarrheaHyperbilirubin. The combination proved at least as effective as TDF+FTC plus lopinavir/r in the ARTEMIS trial. With regard to toler- ance (diarrhea, lipid changes) it was even better (Ortiz 2008). The effects remain stable out to 192 weeks (Orkin 2013). In a small study, the metabolic profile was comparable to atazanavir (Aberg 2013). The resistance barrier is very high and resist- ance mutations during first-line are rarely seen. Gastrointestinal symptoms may occur in some patients. In FLAMINGO and ACTG 5257, these problems led to slightly inferior results compared to the integrase inhibitors dolutegravir and raltegravir, respectively (Clotet 2014, Lennox 2014). An advantage of this combination is the once-daily dosing. Darunavir can also be boosted with cobicistat (Kakuda 2014). Recently, the FDA and EMA have granted marketing approval to the fixed-dose combination of darunavir and cobicistat (Prezcobix or Rezolsta), reducing the pill burden to two tablets with this regimen. TDF+FTC plus atazanavir/r/c: In the CASTLE trial, atazanavir/r proved virologically equal to lopinavir/r, but with better lipids and similar tolerance (Molina 2010). Although a randomized study showed no difference between unboosted and boosted atazanavir (Malan 2008, Squires 2009), boosting with ritonavir is recommended. The main arguments in favour of this combination are the low number of pills and the good lipid profile (compared to lopinavir/r) which, however, does not differ from darunavir (Aberg 2013). The major disadvantage is hyperbilirubinemia, which often manifests as harmless but disturbing icterus. In ACTG 5257, at least 8% of the patients on atazanavir/r (combined with TDF+FTC or ABC+3TC) discontinued their ART due 192 ART to icterus (Lennox 2014). Recently, the FDA and EMA have granted marketing approval to the fixed-dose combination of atazanavir and cobicistat (Evotaz), reducing the pill burden to two tablets with this regimen. TDF+FTC or ABC+3TC plus lopinavir/r have been categorized in many guidelines as a preferred combination. However, after the results of CASTLE, ARTEMIS and ACTG 5142 (see above), lopinavir/r was down-graded in the US (by the DHSS) to an “alter- native” regimen. More data is available for TDF+FTC as a backbone for lopinavir/r, although the HEAT study did not find significant differences compared to ABC+3TC (Smith 2008). Since 2009 lopinavir/r has also been licensed for once-daily use, after several studies showed similar efficacy and tolerability (Molina 2007, Gathe 2009). However, there is some evidence that the potency of once-daily dosing is slightly less than with BID (Ortiz 2008, Flexner 2010). Lopinavir/r lost its main disadvan- tage of requiring cool storage compared to other boosted PIs with the introduction of the Norvir tablets in 2010. The main problem with this regimen are the some- times intense diarrhea, leading to high discontinuation rates. Recently, some studies on dual therapy with lopinavir/r plus 3TC have been published (see below Nuke-S sparing). ABC+3TC (or TDF+FTC) plus fosamprenavir/r: In the KLEAN study, this combi- nation proved almost equal to ABC+3TC plus lopinavir/r in regard to both efficacy and tolerability. Better rates of diarrhea or cholesterol levels were, however, not achieved (Eron 2006). In the ALERT study, fosamprenavir/r was as effective as atazanavir/r, both combined with a TDF+FTC backbone (Smith 2006). In Europe, once daily use of fosamprenavir/r has not been licensed, although using a low booster of 100 mg ritonavir should be possible (Hicks 2009, Cohen 2010). TDF+FTC plus saquinavir/r: Saquinavir was the first PI which showed a survival benefit (Stellbrink 2000). In the relatively small GEMINI study saquinavir/r with a TDF+FTC backbone proved to be non-inferior to lopinavir/r (Walmsley 2009). The even smaller BASIC study showed that a once-daily dosing (1000/100) was compa- rable to atazanavir/r with regard to lipid profiles (Vrouenraetes 2009). The main disadvantage of saquinavir-based regimens is the twice-daily dosing, the high pill burden and a QT prolongation (ECG monitoring required! Recently, however, generics of saquinavir have been introduced to the market. Two NRTIs plus one integrase inhibitor Raltegravir was licensed as the first integrase strand transfer inhibitor (INI) for first- line treatment in 2009. In the meantime, elvitegravir and dolutegravir were licensed by the FDA and the EMA. Convincing long-term data covering a period of 3-5 years, especially regarding tolerability, are lacking. However, there is no doubt that INI-based regimens will be of growing impor- tance in first-line therapy during the next years. TDF+FTC (TDF+3TC) plus raltegravir: in the large STARTMRK trial, raltegravir proved at least as effective as efavirenz (Lennox 2010). Viral load decreased more rapidly in the raltegravir arm and CD4 T cell counts increased. In addition, toler- ance was better and effects lasted over 196 weeks (Rockstroh 2011). It should be noted that data is available for raltegravir with TDF-based backbones while data for ABC+3TC or other backbones is still very limited. A pilot study with ABC+3TC plus raltegravir, however, showed no negative effects (Young 2010). Unfortunately, once- daily dosing of raltegravir is not possible (Vispo 2010, Eron 2011). This is why MSD is working hard on a new formulation, allowing QD use (2 600 mg tablets). What to start with 193 advantage of raltegravir-based regimens are the excellent tolerability and the low potential for interactions. This may be used in patients with comedications, especially chemotherapies or tuberculostatics. TDF+FTC plus elvitegravir/c: was approved as a single tablet regimen (STR, Stribild) in June 2013. Two large Phase III trials yielded excellent results: In 236-0102 and 0103, elvitegravir/c has shown at least comparable efficacy over 144 weeks with efavirenzand atazanavir/r (Clumeck 2014, Wohl 2014). Tolerability was good, except for some more cases of nausea and diarrhea. However, the combination of tenofovir and cobicistat may be problematic as both agents interact primarily with distinct renal transporters. Cobicistat inhibits renal tubular secretion of creatinine and increases serum creatinine levels, resulting in a decrease in estimated glomerular filtration rate (GFR) without a true decline in GFR. Thus, it may be difficult to distinguish between these effects and the “true” renal toxicity of tenofovir.
