It is a prodrug requiring biotransformation into the active metabolite by the hepatic cytochrome 450 system, especially the CYP2C19 enzyme. Candidate gene studies and genome-wide association studies have identified loss-of-function CYP2C19 variants to be associated with a diminished pharmaco- logic response. Specifically, compared with noncarriers, carriers of at least one copy of a loss-of-function CYP2C19 allele have 30% lower levels of active clopidogrel metabolite and 25% relatively less platelet inhibition with clopidogrel. Moreover, in patients treated with clopidogrel predominantly for percutaneous coronary intervention, carriers of 1 or 2 CYP2C19 loss-of-function alleles are at increased risk for major adverse cardiovascular outcomes, with an 1. Tripling the dose of clopidogrel in carriers of a CYP2C19 loss-of-function allele can achieve on-treatment platelet reactivity comparable to that seen with the standard 75 mg dose in wild-type individuals, but the impact on clinical outcomes remains unknown. Alternatively, 2 third-generation P2Y12 inhibitors are available: prasugrel and ticagrelor. These drugs are superior to clopidogrel in reducing ischemic outcomes and are unaffected by CYP2C19 loss-of-function alleles.

Given that the ● To understand the importance of pharmacogenetics with typical lifespan of a platelet is 7-10 days, a return to normal platelet regard to the pharmacologic and clinical efficacy of P2Y12 reactivity in an individual occurs over several days. ADP receptor inhibitors Variable response to clopidogrel Background Variable platelet inhibition with clopidogrel therapy has been Clopidogrel, an inhibitor of the P2Y12 ADP receptor on the surface observed and approximates a bell-shaped distribution, with close to of platelets, is one of the most widely prescribed drugs in 1/3 of subjects not having an appreciable decrease in platelet cardiovascular medicine. Clopidogrel, or earlier generations of reactivity after a standard 300 mg loading dose. Several studies have P2Y12 inhibitors, have been shown to reduce the risk of adverse gone on to show that patients treated with clopidogrel who have clinical outcomes in patients with coronary disease in 2 major high on-treatment platelet reactivity have a higher rate of ischemic settings. First, among patients undergoing coronary stenting, dual complications such as myocardial infarction and stent thrombosis antiplatelet therapy with aspirin and a P2Y ADP receptor inhibitor and, conversely, as would be expected, lower rates of bleeding. In particular, some ing with an acute coronary syndrome (ACS), the addition of proton pump inhibitors (PPIs), such as omeprazole, are both clopidogrel to aspirin reduces the risk of death and ischemic inhibitors of and substrates for the CYP2C19 enzyme, which is complications by 20%. Initial observational data raised concerns about potential association of concurrent PPI Clopidogrel, a thienopyridine, is a prodrug. Absorption of clopi- (especially omeprazole) and clopidogrel therapy with increased dogrel is limited by the intestinal efflux transporter P-glycoprotein. The remaining 15% of concomitant use of omeprazole can decrease levels of the active the prodrug is metabolized by the hepatic cytochrome 450 system, clopidogrel metabolite by 40%–45% and decrease platelet inhibi- especially the CYP2C19 enzyme, into an active thiol metabolite. Food and Drug Administration (FDA) continues and ischemic complications by 75%–85% compared with aspirin to mandate that the clopidogrel prescribing information include the monotherapy or aspirin plus an anticoagulant. Therefore, the risk ratio in that subgroup versus “PPIs are appropriate in patients with multiple risk factors for GI wild-type patients would be the inverse of the benefit of P2Y 12 bleeding who require antiplatelet therapy. Routine use of either a inhibition in that population or 1/0. Due to redundancy in PPI or an H2RA (H2-receptor antagonist) is not recommended for the system, the presence of the CYP2C19*2 allele does not patients at lower risk of upper GI bleeding. For the sake of argument, if one were to clopidogrel, it would be prudent to choose such a drug over PPIs assume a linear relationship between platelet inhibition and reduc- that are known CYP2C19 inhibitors. In contrast, for patients who are predominantly metabolism (CYP2C19, possibly PON1) of clopidogrel have been medically managed, the addition of clopidogrel to aspirin reduces investigated for potential association with clopidogrel response. Partial genetic blockade would then be CYP2C19 expected to result in a risk ratio of only 1. The CYP2C19 gene is polymorphic, with known loss-of-function and gain-of-function variants. Among the The enhanced function CYP2C19*17 variant has also been reported loss-of-function variants, such as the *2, *3, *4, *5, *6, *7, *8 to influence the response to clopidogrel.

MS drugs addendum: fingolimod 14 of 32 Final Original Report Drug Effectiveness Review Project Key Question 1. What is the comparative effectiveness of fingolimod and other disease-modifying treatments for multiple sclerosis, including use of differing routes and schedules of administration? Detailed Assessment Direct evidence There was moderate strength of evidence that fingolimod resulted in lower annualized relapse rates than interferon beta-1a, but that progression of disease was not different between the treatments after one year of treatment. In a single fair-quality head-to-head trial, fingolimod was 18 compared with interferon beta-1a in patients with relapsing-remitting multiple sclerosis. The trial was large, relative to other trials of drugs to treat multiple sclerosis, enrolling 1292 patients who were randomized to a low-dose fingolimod group (0. The primary outcome measure, annualized relapse rate, was significantly lower with either dose of fingolimod compared with interferon beta-1a, but no difference between the doses was found (Table 3). Other measures of relapse (relapse-free, proportion with multiple relapses, and the time to first relapse) also showed both fingolimod doses to be superior. However, the numbers needed to treat for the proportion relapse-free with fingolimod compared with interferon beta-1a at 1 year were not very small (8. The benefit of fingolimod over interferon beta-1a was greater in the subgroup of patients who had prior exposure to a disease-modifying drug than in patients who had no prior exposure. Among patients with prior exposure, the benefit from fingolimod over interferon beta-1a ranged from 0. While the difference in annualized relapse rate between those with prior exposure and those without was not statistically significant, the sample sizes may have been too small to identify the difference as significant. Trial eligibility criteria required that participants had experienced at least 1 documented relapse during the previous year or at least 2 documented relapses during the previous 2 years. Although the trial used a double-dummy design, patients with prior experience with interferon may have been more likely to have guessed which treatment they were on, due to previously experiencing adverse effects associated with interferons but not fingolimod, such as injection site reactions.

Furthermore buy 40 mg cialis extra dosage with mastercard, children also showed greater improvements in ADHD symptoms with immediate-release methylphenidate generic cialis extra dosage 60mg amex, immediate-release dextroamphetamine cialis extra dosage 40mg without a prescription, and atomoxetine compared with placebo generic cialis extra dosage 40 mg free shipping. Observational evidence of the impact of immediate-release methylphenidate treatment indicates that the baseline frequency and severity of motor and vocal tics was significantly higher than during the placebo phase of the study discount cialis extra dosage 40mg online, and no differences were found among the placebo and 12, 18, and 24 month immediate- 395 release methylphenidate treatment follow-up periods. Nonstimulants: Guanfacine In a small study of 24 children with ADHD, all of the mixed type and a tic disorder, studied the 159 effects of guanfacine compared with placebo for 8 weeks. Slightly more than half of enrolled children had Tourette’s disorder (58. In this study, the mean Yale Global Tic Severity Scale scores improved in children taking guanfacine (–4. Substance use disorder Adolescents Two placebo-controlled trials, 1 of methylphenidate-SODAS and 1 of atomoxetine focused on 396, 397 the subpopulation of substance use disorder with differing results. The small (N=16) 6- week, single-blind, placebo-controlled crossover study of methylphenidate SODAS in Attention deficit hyperactivity disorder 112 of 200 Final Update 4 Report Drug Effectiveness Review Project adolescents with ADHD and comorbid substance use disorder (marijuana N=16 and cocaine N=7) found that methylphenidate SODAS was superior to placebo in reducing ADHD symptoms and improving global functioning for all main outcome measures (SNAP-IV and Clinical Global 396 Impression Scale scores; P values for all measures were <0. There was no significant treatment effect on drug use (number of marijuana cigarettes daily; urine tests for either cannabis or cocaine). A 12-week, double-blind, parallel group placebo-controlled trial of atomoxetine (N=70) in adolescents with at least 1 non-nicotine substance-use disorder found that atomoxetine was not statically different to placebo in improving ADHD symptoms or substance use (self-report DSM 397 IV ADHD checklist mean change –18. Number of days using non nicotine substances was also not statistically significantly different, although numerically was lower in the atomoxetine group (–5. Importantly, in this study both groups received non drug treatments that may have had significant impact on the results. Adults Placebo-controlled trials of atomoxetine, immediate-release methylphenidate, and methylphenidate SR have evaluated treatment of ADHD in adults with comorbid substance abuse. Atomoxetine treatment has been assessed in a 12-week placebo-controlled trial of 398 147 adults with ADHD and comorbid alcohol use disorders. In this trial, reductions in ADHD symptoms, as measured by reductions in the Total Score on the ADHD Investigator Symptom Rating Scale (AISRS), were significantly greater for atomoxetine (–13. The atomoxetine group also made significant improvement relative to placebo on the Clinical Global Impression-ADHD-S (P=0. There were no significant differences in time to relapse between the 2 treatments (P=0. Another trial of atomoxetine in marijuana-dependent adults with ADHD was rated poor quality primarily due to an unacceptable level of attrition (65%), inadequate reporting of 197 randomization methods, and the resulting baseline comparability of all randomized patients. Results of an exploratory, post-hoc analysis of 17 adults with ADHD and 382 substance use disorder was reported based on data from a fair-quality, 4-week, randomized, placebo-controlled trial of lisdexamphetamine 30 mg, 50 mg, and 70 mg in 420 adults (54% 201 men, mean age of 35. The significant improvement in ADHD-RS scores with lisdexamfetamine was observed both in patients with and without a history of substance use disorder. Two trials of immediate-release 208, 215 231, 233, 234 methylphenidate and 3 trials of methylphenidate SR focused only on patients with ADHD and comorbid substance abuse disorders. One trial of immediate-release methylphenidate 208 involved a broader population of patients with any alcohol or drug dependence, while the 215, 231 others focused on either patients with cocaine dependence, methadone-maintained 233 234 patients, or amphetamine abuse. The primary objectives of these trials were to investigate Attention deficit hyperactivity disorder 113 of 200 Final Update 4 Report Drug Effectiveness Review Project (1) whether use of immediate-release methylphenidate or methylphenidate SR in adult substance abusers with ADHD reduces ADHD symptoms to a similar extent as in non-substance abusers and with ADHD, and (2) what kind of impact immediate-release methylphenidate or methylphenidate SR use may have on the course of the substance abuse disorder. Overall, although use of immediate-release methylphenidate or methylphenidate SR in adult substance abusers with ADHD did not appear to negatively influence the course of the substance abuse disorder recovery process (cravings, abstinence duration, proportion of days of substance use, 215, amount of money spent on substances, or number of days until first negative urine sample), 231, 233 immediate-release methylphenidate or methylphenidate SR also did not appear to offer 208, 215, 231, 233, 234 much of a benefit in the reduction of these patients’ ADHD symptoms. Among the trials that reported response rates, in all but 1 of these trials, not only were there less robust treatment response rates in substance abusers with ADHD compared with non-substance abusers (34% to 47% compared with 38% to 78%), but the placebo response rates in the substance 208, abuser trials were also substantially greater (ranges 21% to 55% compared with 4% to 16%). What is the comparative or noncomparative evidence of misuse or illicit diversion of pharmacologic treatments for attention deficit disorders in patients with current or past substance use disorder comorbidities? Adolescents A retrospective chart review of 450 teens treated at a substance abuse center in Canada from 1993 to 1999 examined the prevalence of abuse of methylphenidate or immediate-release 399 dextroamphetamine. Twenty-three percent had ever used, and 6% were currently using methylphenidate or immediate-release dextroamphetamine, most often reported to be used as crushed tablets taken intranasally. Further assessment of covariates indicated that higher rates of abuse of methylphenidate or immediate-release dextroamphetamine were associated with the teen being out of school or having an eating disorder (P<0. An assessment of correlation of abuse of methylphenidate or immediate- release dextroamphetamine with abuse of other substances did not reveal any statistically significant results. The authors note that this population had a higher psychiatric comorbidity rate than the general adolescent population, which may have affected the results.
