You are asked by the emergency medicine physician whether hemodialysis should be considered to decrease the patient’s plasma dabigatran level. Published reports have shown Learning Objective that 4 hours of hemodialysis can reduce the plasma concentration of ● To describe recommendations for or against the use of dabigatran by 59%-68%,13,14 although drug levels can increase after hemodialysis for dabigatran-associated major bleeding and intermittent dialysis sessions due to redistribution from extravascu- the underlying evidence, based on a review lar compartments. Keywords “dabigatran” (1979 hits), “hemodialysis” (56 risk reduction of stroke and embolism associated with atrial hits), and “hemorrhage” or “bleeding” yielded 41 articles. Of ﬁbrillation (AF), as well as treatment and secondary prevention of 1 these, 32 articles were excluded: 7 were non-English, 21 did not venous thromboembolism. After absorption and conversion to its include original data, 1 was a survey, 1 did not involve active form, dabigatran reversibly binds to thrombin’s active site, hemodialysis, and 2 did not involve bleeding. Nine studies were preventing its conversion of ﬁbrinogen to ﬁbrin. Dabigatran’s plasma included: 1 retrospective database review, 2 retrospective case concentration peaks within 1. Dabigatran is primarily excreted through the kidneys (85%), with the remainder excreted in the bile. All except 1 patient took dabigatran bleeding associated with dabigatran 150 mg twice daily versus 3 for AF. GI bleeding was present in 5, traumatic intracranial warfarin among AF patients, which was corroborated in a recent meta-analysis of randomized controlled trials also showing an hemorrhage in 3, and the remaining 3 cases involved hemoptysis, increased risk of GI bleeding with dabigatran compared with cutaneous bleeding, and postoperative bleeding.

Adjunctive therapies such as blood products, Only low-quality evidence is available to support the use of prothrombin complex concentrates, and recombinant factor VIIa hemostatic agents such as prothrombin complex concentrates. Only 2 of the 11 cases resulted in death due to Gastric lavage or activated charcoal can reduce GI absorption only uncontrolled hemorrhage, both of which occurred despite continu- if the last dose of dabigatran was taken within 2 hours of the major ous hemodialysis or hemodiaﬁltration. Among those who died, 6 of 13 (46%) underwent hemodialysis, all of whom had at least some degree of renal insufﬁciency. However, the risk of placing a large-caliber venous catheter and the time to arrange and perform hemodialysis must also be consid- ered. Clinical trials to evaluate antidotes against dabigatran should be pursued. In a patient with serious (life-threatening) dabigatran-associated bleeding and a calculated creatinine clearance of 30 mL/min, we suggest that hemodialysis be performed if emergent hemodialysis is available and if appropriate vascular access can be obtained (grade 2C).

Adverse events in placebo-controlled trials of atomoxetine Author Year Treatment Withdrawals due to Appetite Sample size regimen adverse events disturbance Insomnia Spencer “Occurred “Did not occur 192 76 mg x 3 1998 4% vs generic malegra fxt plus 160mg amex. Immediate-release dextroamphetamine 198 discount malegra fxt plus 160 mg on-line, 199 Some reporting of adverse events was available in both of 2 fair-quality trials generic 160 mg malegra fxt plus free shipping. Between- group statistical comparisons were not reported in the 6-week trial of 51 adults generic malegra fxt plus 160mg without a prescription, but rates were generally higher for immediate-release dextroamphetamine 23 order malegra fxt plus 160 mg visa. In the second trial of 98 adults, after 20 weeks there was no significant difference between immediate-release dextroamphetamine 20 mg twice daily or placebo in withdrawals due to adverse events (13% compared with 8%), but rates of individual adverse events were not 198 reported. Attention deficit hyperactivity disorder 80 of 200 Final Update 4 Report Drug Effectiveness Review Project Extended-release dexmethylphenidate We included 1 fair-quality, placebo-controlled trial of 5 weeks of treatment with extended- 200 release dexmethylphenidate (N=221). There was no significant difference between extended- release dexmethylphenidate and placebo in withdrawals due to adverse events (11% compared with 8%), decreased appetite (18% compared with 11%), or insomnia (16% compared with 11%). Lisdexamfetamine 201 202 We included 1 fair-quality trial and 1 poor-quality trial of lisdexamfetamine. In the fair- quality trial, rates of various common adverse events were reported for lisdexamfetamine and placebo, but statistical analysis of between-groups differences was not reported. For lisdexamfetamine 30 mg, 50 mg, 70 mg, and placebo, respectively, rates of withdrawals due to adverse events were 3%, 7%, 7%, and 2% and rates of decreased appetite were 29%, 28%, 23%, and 2%. Using data from this trial, analysis of numerous aspects of the impact lisdexamfetamine had on sleep quality was presented in a subsequent publication. It was unclear whether all the sleep analyses were prespecified. Although statistical analysis of between-group differences was not reported, the rates of treatment-emergent insomnia were numerically greater for all 3 doses of lisdexamfetamine compared with placebo and a dose-response may have been in effect (19% 243 for 30 mg, 17% for 50 mg, and 21% for 70 mg compared with 5% for placebo). Mixed amphetamine salts immediate-release We included 1 fair-quality, crossover trial that compared 3 weeks of treatment with mixed amphetamine salts immediate-release 54 mg to placebo in 30 adults (50% male, mean age of 38 204 years). Compared to placebo, there was a significantly greater proportion of patients taking mixed amphetamine salts immediate-release with a loss of appetite (30% compared with 11%; P=0. Withdrawals due to adverse events were not reported. Mixed amphetamine salts extended-release Both of 2 fair-quality included trials of mixed amphetamine salts extended-release reported rates of various common adverse events, but results of a statistical comparison to placebo were not 193, 205 reported. In the first 4-week trial (N=255), for mixed amphetamine salts extended-release 20 mg, 40 mg, 60 mg, and placebo, respectively, rates of adverse event withdrawals were 14%, 9%, 13%, and 2%; rates of anorexia were 20%, 42%, 38%, and 3%; and rates of insomnia were 205 21%, 30%, 26%, and 13%. In the second 3-week trial of 19 young adults, for mixed amphetamine salts extended-release 50 mg and placebo, respectively, rates of adverse event withdrawals were 11% and 10%, rates of anorexia were 50% and 0%, and rates of insomnia were 193 19% and 0%. Immediate-release methylphenidate Adverse event report was extremely limited in trials of immediate-release methylphenidate. Withdrawals due to adverse events were only reported in 2 trials and rates for immediate-release methylphenidate and placebo, respectively, were 9% and 2% after 3 weeks (N=23; P not 217 213 reported) and 25% and 9% after 7 weeks (N=30, P not reported). In the 2 trials that reported sleep difficulties, there were no significant differences between immediate-release methylphenidate and placebo at 2 weeks (mild trouble sleeping, 22% compared with 17%; Attention deficit hyperactivity disorder 81 of 200 Final Update 4 Report Drug Effectiveness Review Project moderate trouble sleeping, 4% compared with 8%; severe trouble sleeping, 0% compared with 207 212 4%) or at 3 weeks (sleeping problems, 33% compared with 22%). In those same 2 trials, regarding appetite loss, the difference between immediate-release methylphenidate and placebo was not significant at 2 weeks (23% compared with 5%; N=38) but was significant at 3 weeks (22% compared with 4%; P=0. No differences were found in 5 of 6 assessments, although the immediate-release methylphenidate group experienced fewer nocturnal awakenings (0. Methylphenidate extended-release We included 1 fair-quality trial that compared 24 weeks of treatment with methylphenidate 223 extended-release 41. Withdrawals due to adverse events (13% compared with 8%), decreased appetite (38% compared with 13%), and difficulties falling asleep (25% compared with 18%) were described as “more frequent” with methylphenidate extended-release compared with placebo, but P values were not provided. Methylphenidate OROS Adverse events were reported in all 6 fair-to good-quality included placebo-controlled trials of 225-230 methylphenidate OROS (Table 13). However, statistical comparison of methylphenidate 228-230 OROS and placebo was only undertaken in 3 trials. In those trials, rates of decreased appetite were consistently significantly greater for methylphenidate OROS compared with placebo. Otherwise, for adverse event withdrawals and insomnia, differences between methylphenidate OROS and placebo did not consistently reach statistical significance.

Three of the trials 233 231 focused on subgroups of adults who were methadone-maintained cocaine-dependent or 234 amphetamine abusers and results from these will be discussed in Key Question 3. Methylphenidate transdermal system No data was available regarding the adverse event profile of methylphenidate transdermal 235 system, as the single included placebo-controlled trial was rated poor quality.
