Anticonvulsant Meds and Suicide Risk

JAMA — Abstract: Anticonvulsant Medications and the Risk of Suicide, Attempted Suicide, or Violent Death, April 14, 2010, Patorno et al. 303 (14): 1401

Results: The study identified 26 completed suicides, 801 attempted suicides, and 41 violent deaths in 297 620 new episodes of treatment with an anticonvulsant (overall median follow-up, 60 days). The incidence of the composite outcomes of completed suicides, attempted suicides, and violent deaths for anticonvulsants used in at least 100 treatment episodes ranged from 6.2 per 1000 person-years for primidone to 34.3 per 1000 person-years for oxcarbazepine. The risk of suicidal acts was increased for gabapentin (hazard ratio [HR], 1.42; 95% confidence interval [CI], 1.11-1.80), lamotrigine (HR, 1.84; 95% CI, 1.43-2.37), oxcarbazepine (HR, 2.07; 95% CI, 1.52-2.80), tiagabine (HR, 2.41; 95% CI, 1.65-3.52), and valproate (HR, 1.65; 95% CI, 1.25-2.19), compared with topiramate. The analyses including violent death produced similar results. Gabapentin users had increased risk in subgroups of younger and older patients, patients with mood disorders, and patients with epilepsy or seizure when compared with carbamazepine.

Conclusion: This exploratory analysis suggests that the use of gabapentin, lamotrigine, oxcarbazepine, and tiagabine, compared with the use of topiramate, may be associated with an increased risk of suicidal acts or violent deaths.

Combination Therapy for Crohn’s

Better Treatment Found for Crohn’s Disease – BusinessWeek

The international trial included 508 people with Crohn’s disease who had never been treated with immunosuppressive drugs. One-third were given infliximab alone, one-third received only azathioprine and one-third were treated with both. The trial was funded by Centocor Ortho Biotech, which markets infliximab, and Schering-Plough.

After 26 weeks, 56.8 percent of those getting combination therapy had complete remission of symptoms, compared to 44.4 percent of those getting only infliximab and 30 percent of those getting only azathioprine.

Don’t Take Plavix if You Are a Poor Metabolizer

A “poor metabolizer” does not effectively convert Plavix to its active form because of low CYP 2C19 activity.

How does someone figure out they are a “poor metabolizer”?

Read the FDA communication if you’re seriously interested in the answer to this question.

FDA Drug Safety Communication: Reduced effectiveness of Plavix (clopidogrel) in patients who are poor metabolizers of the drug

The U.S. Food and Drug Administration (FDA) has added a Boxed Warning to the label for Plavix, the anti-blood clotting medication. The Boxed Warning is about patients who do not effectively metabolize the drug (i.e. “poor metabolizers”) and therefore may not receive the full benefits of the drug.

Venlafaxine and SCD Risk

Use of venlafaxine compared with other antidepressants and the risk of sudden cardiac death or near death: a nested case-control study — Martinez et al. 340: c249 — BMJ

Conclusions In this large, population based study, the use of venlafaxine was not associated with an excess risk of sudden cardiac death or near death compared with fluoxetine, dosulepin, or citalopram, in patients with depression or anxiety.

ASA May Reduce CVD and All-Cause Mortality in T2DM

Aspirin Is Associated With Reduced Cardiovascular and All-Cause Mortality in Type 2 Diabetes in a Primary Prevention Setting — Diabetes Care

RESULTS There were 160 deaths (24.6%) during follow-up, with 70 (43.8%) due to CVD. In Kaplan-Meier survival analysis, there was no difference in either CVD or all-cause mortality in aspirin users versus nonusers (P = 0.52 and 0.94, respectively, by log-rank test). After adjustment for significant variables in the most parsimonious Cox models, regular aspirin use at baseline independently predicted reduced CVD and all-cause mortality (hazard ratio [HR] 0.30 [95% CI 0.09–0.95] and 0.53 [0.28–0.98[, respectively; P ≤ 0.044). In subgroup analyses, aspirin use was independently associated with reduced all-cause mortality in those aged ≥65 years and men.

CONCLUSIONS Regular low-dose aspirin may reduce all-cause and CVD mortality in a primary prevention setting in type 2 diabetes. All-cause mortality reductions are greatest in men and in those aged ≥65 years. The present observational data support recommendations that aspirin should be used in primary CVD prevention in all but the lowest risk patients.
