Objective: This post hoc study investigated the relationship between patient response in terms of migraine headache day reduction and patient-reported outcomes of health-related quality of life (HRQoL) and disability categories.
Background: Migraine causes considerable disease-related disability and negatively impacts HRQoL of patients. Calcitonin gene-related peptide inhibitors improve these outcomes and may eliminate disability due to migraine in some patients.
Introduction: Acute medication overuse is prevalent in patients with migraine.
Methods: In three phase 3, double-blind, randomized, placebo-controlled studies, patients with episodic migraine (EVOLVE-1 and EVOLVE-2) or chronic migraine (REGAIN) were randomized 2:1:1 to monthly subcutaneous injections of placebo or galcanezumab 120 or 240 mg for 3 or 6 months. This subgroup analysis evaluated mean changes in the number of monthly migraine headache days in each treatment among patients with versus without baseline acute medication overuse via mixing modelling with repeated measures.
Background: Migraine is recognized as the second leading cause of disability globally. Lasmiditan is a novel, selective serotonin 5-HT receptor agonist developed for acute treatment of migraine. Here we analyzed effects of lasmiditan on migraine disability assessed with the Migraine Disability Assessment (MIDAS) scale for interim data from a long-term safety study.

Study Design/methods: REGAIN (NCT02614261) was a Phase 3, randomized, double-blind, placebo-controlled study in patients with chronic migraine.
Background: Effects of galcanezumab, a monoclonal antibody against calcitonin gene-related peptide, on patient satisfaction, health care resource utilization (HCRU), and acute medication use were evaluated in a long-term, open-label study in patients with migraine.
Methods: Patients with episodic (78.9%) or chronic migraine (21.
Objective: To evaluate the association between intermittent phosphodiesterase type 5 inhibitor (PDE5i) exposure and risk of acute nonarteritic anterior ischemic optic neuropathy (NAION) using a case-crossover design.
Methods: Male adults with suspected NAION were enrolled at 41 US ophthalmology sites from 2010 to 2015 and were interviewed regarding risk factors for NAION, medical history, and PDE5i use before NAION onset (index date of onset [IDO]). An adjudication committee confirmed the NAION cases.

Objective: To analyze Clinical Global Impression-Severity (CGI-S) in ADHD patients treated with atomoxetine (ATX) monotherapy versus ATX combination therapy with another ADHD-indicated medication.
Methods: This was a 2-site retrospective observational chart review study of child and adult ADHD patients, not necessarily treatment naïve, but treated ≥50 days post baseline with an endpoint assessment. To adjust for measured confounders, monotherapy (n = 77) versus combination (n = 108) cohort comparisons were performed using propensity score stratification and adjusted ANCOVA.
This study evaluated the effect of axillary administration of a 2% testosterone solution (Axiron) in hypogonadal (HGN) men who had had a suboptimal response to treatment with a commercially available topical testosterone gel. HGN men averaging 57 years old, with a mean body mass index of 31.9 kg/m and median baseline testosterone level (T-level) of 185.

Objective: Our aim was to determine how long to treat osteoarthritis (OA) knee pain and chronic low back pain (CLBP) with duloxetine before considering a change in medication strategy.
Methods: We employed a post hoc analysis of changes in pain-severity data from placebo-controlled studies of duloxetine treatment in nondepressed patients with OA knee pain and CLBP.
Objective: Examine how different dosing schedules and recent stimulant therapy effect incidence, time to onset, and duration of common treatment-emergent adverse events (TEAEs) during atomoxetine treatment.
Method: Post hoc analyses including safety data (open-ended questions) from 22 pediatric and 3 adult atomoxetine trials (1998-2009) in patients with attention-deficit/hyperactivity disorder. Most common TEAEs were determined by incidence rates and frequency of consumer and clinician inquiries.
Objective: Response to atomoxetine, a nonstimulant norepinephrine-specific reuptake inhibitor, was compared with the effect of osmotic-release oral methylphenidate, a long-acting methylphenidate preparation, in patients with attention deficit hyperactivity disorder (ADHD).
Method: In a large placebo-controlled, double-blind study, patients ages 6-16 with ADHD, any subtype, were randomly assigned to receive 0.8-1.

Objective: To examine the effects on growth of long-term pharmacological treatment for attention-deficit/hyperactivity disorder (ADHD), we present findings from an ongoing 5-year study of the efficacy and safety of treatment with atomoxetine.
Methods: North American patients, 6-17 years old at study entry (N = 1,312) and with Diagnostic and Statistical Manual of Mental Disorders,4th edition (DSM-IV) ADHD, were studied under open-label atomoxetine treatment. Sixty-one were studied up to 5 years.

Objective: To assess the utility and tolerability of higher than standard atomoxetine doses to treat attention-deficit/hyperactivity disorder (ADHD).
Method: Two randomized, double-blind trials of atomoxetine nonresponders ages 6 to 16 years were conducted comparing continued treatment with same-dose atomoxetine to treatment using greater than standard efficacious doses (study 1: up to 3.0 mg .

Background: Atomoxetine, a selective norepinephrine reuptake inhibitor effective in the treatment of attention-deficit/hyperactivity disorder (ADHD), is metabolized through the cytochrome P-450 2D6 (CYP2D6) enzyme pathway, which is genetically polymorphic in humans. Variations in plasma atomoxetine exposures can occur because of genetic variation or as a consequence of coadministration with drugs that inhibit CYP2D6.
Method: We examined the effects of CYP2D6 on the efficacy, safety, and tolerability of atomoxetine in children and adolescents using pooled data from atomoxetine clinical trials.
Objective: Data from acute studies of atomoxetine in patients with attention-deficit/hyperactivity disorder suggest that a dose of approximately 1.2 mg/kg per day is required to attain a maximal symptom response. However, lower doses could be effective during maintenance treatment, which would reduce drug exposure and potential problems related to tolerability during chronic treatment.
