{"title":"Quantitative Characterization of the Smoothness of Extended-release Methylphenidate Pharmacokinetic Profiles.","authors":"Michelle D Po,&nbsp;Roberto Gomeni,&nbsp;Bev Incledon","doi":"","DOIUrl":"","url":null,"abstract":"<p><strong>Objective: </strong>Extended-release methylphenidate (ER-MPH) formulations used to treat attention deficit hyperactivity disorder (ADHD) have complex pharmacokinetic (PK) profiles, resulting from differing ratios of immediate-release and extended-release components and/or their site of absorption. This study aimed to evaluate the smoothness of PK curves of ER-MPHs.</p><p><strong>Design: </strong>The integral of the second derivative squared was evaluated for modeled PK curves, with smaller values indicating a smoother curve. The calculated smoothness of each PK curve was normalized by dividing by Cmax 2 to derive a normalized smoothness parameter appropriate across the dose range of each formulation. Calculations used modeled PK curves from 100mg delayed-release and ER-MPH (DR/ER-MPH), 54mg osmotic release oral system MPH (OROS MPH), 60mg MPH controlled-release delivery (MPH CD), 60mg ER-MPH oral suspension (MEROS), 20mg ER dexmethylphenidate (d-MPH ER), and 60mg multilayer-release MPH (MLR-MPH).</p><p><strong>Results: </strong>The Cmax2-normalized smoothness value was consistent across DR/ER-MPH doses, allowing for relevant comparisons across formulations. Normalized smoothness values differed widely; the lowest normalized smoothness was 0.05 with DR/ER-MPH and ranged up to 9.56 with d-MPH ER.</p><p><strong>Conclusion: </strong>DR/ER-MPH demonstrated a smoother PK profile compared to the highest dose of other ER-MPH formulations. While the benefits of a smooth PK profile remain to be tested clinically, having fewer peaks and troughs has been hypothesized to reduce waxing and waning of therapeutic effects throughout the day, and more gradual changes in MPH plasma levels have been hypothesized to lower the risk of likeability and potentially abate afternoon symptom rebound.</p>","PeriodicalId":13635,"journal":{"name":"Innovations in clinical neuroscience","volume":"19 7-9","pages":"32-37"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9507140/pdf/icns_19_7-9_32.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33492870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transgender patients are subject to microaggressions, misgendering, and harassment from providers, medical staff, and fellow patients. These patients experience drastic disparities in suicidality, depression, anxiety, substance use, malignancy, sexually transmitted disease (STD), and victimization of violence. Providers have the opportunity to intervene and positively impact patient experiences through gender-affirming care, but they first require an adequate knowledge base and understanding of the importance of sensitive and inclusive care. Seemingly small interventions, such as listing one's own pronouns, using gender-neutral language, validating and affirming patients, and utilizing appropriate mental and physical health screenings, can lead to significant impacts on the patient experience, health outcomes, and quality of life.

Several of these technologies have been incorporated into our ongoing neurology and respiratory clinical development programs. Based on our experience, one of the greatest potential benefits of digital health technologies is the ability to collect objective and/or biological data continuously or at regular intervals outside of office visits during a patient's normal daily activities to provide additional efficacy and safety information, versus data capture from traditional episodic, time point-based office visits. Many challenges encountered with digital health technologies can be successfully addressed by providing the appropriate training to staff and patients, ensuring availability of appropriate infrastructure support, and conducting pilot studies before scaling up to larger trials.
