To the Editor.— The case report of carbamazepine intoxication secondary to isoniazid administration recently described in this journal1 is a clinically significant interaction. I have previously presented2 a similar case in which a patient receiving carbamazepine, valproate, and nitrazepam developed severe carbamazepine intoxication when isoniazid was added to the drug regimen. The patient was determined to have inherited the slow acetylator phenotype. On careful rechallenge, 300 mg of isoniazid increased carbamazepine steady-state serum concentrations by 85% and decreased carbamazepine clearance by 45%.

Abstract Older Veterans represent a unique population at high risk for mobility limitations. They are also more likely to be overweight or obese when compared to the general population. We sought to compare changes in mobility function across the obesity spectrum in older Gerofit participants at six different sites. Two-hundred and seventy Veterans (mean age: 74 years) completed six-months of Gerofit participation and mobility assessments at baseline, three and six months. Our assessments included gait-speed, six-minute walk distance, 30-second chair stands, and the eight foot up and go. When comparing weight groups, we found no significant interaction of weight and time, however we found clinically significant (P<0.02) improvements of 7-20% across all mobility measures. Six-months of Gerofit participation appears to be one way to improve mobility function in older Veterans across the weight spectrum.

Abstract Purpose A case of a possible interaction between cannabidiol and warfarin is presented along with a brief overview of cytochrome enzymes involved in these drugs’ metabolism. Summary A 46-year-old male taking warfarin for treatment of a deep venous thrombosis was initiated on a Food and Drug Administration (FDA)–approved cannabidiol product (Epidiolex, Greenwich Biosciences) for intractable epilepsy. The patient’s International Normalized Ratio (INR) was monitored closely during cannabidiol initiation and dose titration. The patient required a nearly 20% warfarin dose reduction to maintain an INR within the goal range after starting therapy with cannabidiol. There is 1 other case report describing a clinically significant interaction between cannabidiol (specifically Epidiolex) and warfarin in a patient receiving warfarin who was enrolled in a study involving the initiation and titration of cannabidiol; that patient developed a supratherapeutic INR of 6.86 and required a 30% reduction in the weekly warfarin dose to reachieve the goal INR. Conclusion A previously published report suggesting an interaction between cannabidiol and warfarin is supported by this case report. INR should be monitored frequently in patients taking warfarin who begin to take FDA-approved cannabidiol. Additional studies should be performed to clarify the interaction potential of cannabidiol and warfarin.

Background: Histamine (H) 2 blockers led to a significant increase of the relative bioavailability of nimodipine and therefore may change tolerability of nimodipine in patients with aneurysmal subarachnoid hemorrhage (SAH). Objective: To determine the effect of H2 blockers on outcome of SAH patients being treated with nimodipine on outcomes. Methods: We analyzed data from Cerner Health Facts® which collected data from participating facilities from January 1st, 2000 to July 1st, 2018. We identified SAH patients who underwent endovascular or surgical treatment for intracranial aneurysm and received nimodipine with or without H2 blockers. Outcome was defined by discharge destination and classified into none to minimal disability, moderate to severe disability, or death. Results: A total of 815 (54.8%) of 1488 SAH patients received H2 blockers in addition to nimodipine. There were no differences in rates of cerebral ischemia (8.8% versus 9.8%) or performance of angioplasty (3.8% versus 3.7%) between patients who did or did not receive H2 blockers. There were no differences in rates of intubation/mechanical ventilation (26.0% versus 29.3%) or intra-procedural cerebral infarction (3.4% versus 2.8%) between the two groups. There was no difference in in hospital mortality rates (10.9% versus 10.2%) or none to minimal disability (41.8% versus 38.2%) between patients who did or did not receive H2 blockers. Conclusions: H2 blockers are frequently used with nimodipine in SAH patients and did not appear to adversely affect rates of death or disability. The finding does not support any clinically significant interaction between H2 blockers and nimodipine in SAH patients.
