Adherence to levetiracetam for management of epilepsy: Assessment with electronic monitors.

INTRODUCTION: Anti-seizure medications are used to manage epilepsy and require long-term adherence to maintain therapeutic drug levels. We assessed adherence to levetiracetam and the use of a digital intervention to improve adherence in patients with epilepsy. METHODS: 30 participants with epilepsy were randomized 1:1 either to a digital email adherence intervention or control group. All patients were provided levetiracetam equipped with electronic monitoring caps to assess patient adherence to medication. Patients were followed for 6 months, with return visits at 1 month, 3 months, and 6 months. RESULTS: Subjects randomized to the control arm (n = 15) took 66% of the prescribed doses compared to the intervention group, who took 65% of prescribed doses (n = 15). Nine participants did not complete the study. Of the twenty-one participants that completed the study, the overall rate of adherence was 72% of prescribed doses taken. Two subjects in the control group and three subjects in the intervention group were adherent every month of the study-taking at least 80% of prescribed doses. Those randomized to the control group took the correct number of doses 44% of days in the study, and those in the intervention group took the correct number of doses 37% of days. DISCUSSION: Poor adherence to levetiracetam is common. An internet-based email survey intervention did not improve adherence to levetiracetam in epilepsy patients. Further advances in adherence are needed to help patients receive the maximum benefit of their medical treatments.

Compounded Topical Analgesics for Chronic Pain.

Analgesic medications compounded for topical use are gaining popularity for the management of chronic pain. The advantages of topical pain medications include reduction of systemic adverse effects, improved patient acceptance, few drug interactions, ease of dose determination, avoidance of first-pass metabolism, and direct access to the target site. Compounded topical medications typically use a mixture of 3 or more single medications to achieve multiple complementary effects at lower doses of each individual medication. Herein, we review the mechanisms, adverse effects, and evidence for some of the most commonly used medications in topical compounds for pain management. Because more topical medications are used for chronic pain, dermatologists can expect an increase in irritant and allergic contact dermatitis related to these medications.
