The influence of genetic variants related to opioid use disorder (OUD) was evaluated using multiple logistic regression analysis in self-reported assigned African American/Afro-Caribbean and European biogeographical ancestry groups (BGAGs) and by sex. From a sample size of 1301 adult patients (>18 years of age) seen in emergency departments of three medical centers in Ohio, six variants were found to be associated with OUD. Two of the variants, rs2740574 (CYP3A4) and rs324029 (DRD3), were included in the analysis having met criteria of at least five subjects for each BGAG, variant carrier status, and OUD status combinations.

Emergency departments (EDs) in the United States treat millions with OUD annually who may not seek care elsewhere. Our objectives were (1) to compare two screening measures for OUD characterization in the ED and (2) to determine the proportion of ED patients screening positive for OUD and those who endorse other substance use to guide future screening programs.

The core pharmacist competencies in genomics were recently updated and mapped to the entrustable professional activities (EPAs). The new competency that is mapped to the "Interprofessional Team Member" EPA domain emphasizes the role of pharmacists as the pharmacogenomics experts in an interprofessional healthcare team.

Although flualprazolam and flubromazolam are structurally similar to alprazolam, they do not have an approved medical indication. Flualprazolam differs from alprazolam by the addition of a single fluorine atom.

CYP2C19 intermediate and poor metabolizers who receive clopidogrel experience reduced platelet inhibition and increased risk for major adverse cardiovascular and cerebrovascular events. This guideline is an update to the 2013 Clinical Pharmacogenetics Implementation Consortium (CPIC) guideline for the use of clopidogrel based on CYP2C19 genotype and includes expanded indications for CYP2C19 genotype-guided antiplatelet therapy, increased strength of recommendation for CYP2C19 intermediate metabolizers, updated CYP2C19 genotype to phenotype translation, and evidence from an expanded literature review (updates at www.

Genetic counselors are the heart of the treatment team in relation to counseling regarding genetic risk factors and disease states. A framework for treatment within the interdisciplinary team with more defined roles and areas of specialty will need to be in place as this practice approach expands with new data and treatments.

Competencies available through the Genetics/Genomics Competency Center provide a framework for pharmacogenomics instruction in both pharmacy school curricula and continuing education programs. Given the significant advancements in pharmacogenomics over the past decade, the 2019-2020 American Association of Colleges of Pharmacy Pharmacogenomics Special Interest Group updated the pharmacist competencies.

Pharmacogenomics (PGx) is expanding across health-care practice settings, including the community pharmacy. In the United States, models of implementation of PGx in the community pharmacy have described independent services and those layered on to medication therapy management. The drug-gene pair of clopidogrel- has been a focus of implementation of PGx in community pharmacy and serves as an example of the evolution of the application of drug-gene interaction information to help optimize drug therapy.

When considering the increased sensitivity that older patients have to medications, the inclusion of pharmacogenomics (PGx) information can be of great importance. Understanding the consequences of phenoconversion can further expand the role of PGx in patient care.
View Article and Find Full Text PDFPharmacogenomics (PGx), the study of how an individual's genetic makeup affects his or her response to drugs, is a fast-growing field that gives health care providers a valuable tool to help safely and effectively manage medication. However, few providers have experience in applying the results of PGx tests to their practices, and this can lead to disregarding the data or unnecessarily modifying medication regimens. Pharmacists are uniquely positioned to become wellversed in the interpretation of PGx data, critically evaluating the "green-yellow-red" result categories that seemingly signal "go, caution, stop" regarding the use of a particular medication.

As medication experts with education in pharmacology, pharmacokinetics, and pharmacodynamics, pharmacists must further their education to include pharmacogenomics. Currently, few opportunities exist to gain this type of education, and therefore, these services are not yet broadly available to the public.

Studies with MDMA, suggests that there may be male and female pharmacokinetic and pharmacodynamic differences. In the present study, we present the plasma pharmacokinetic data relative to a 20 mg/kg, subcutaneous doses of methylone, butylone and pentylone in female Sprague-Dawley rats.
View Article and Find Full Text PDFRationale: The synthetic cathinones are a class of designer drugs of abuse that share a common core scaffold. The pharmacokinetic profiles of the synthetic cathinones vary based on the substitutions to the core scaffold.
Objectives: To provide a summary of the literature regarding the pharmacokinetic characteristics of the synthetic cathinones, with a focus on the impact of the structural modifications to the pharmacokinetics.
Aim: To systematically assess methodological quality of pharmacogenomics clinical practice guidelines.
Methods: Guidelines published through 2017 were reviewed by at least three independent reviewers using the AGREE II instrument, which consists of 23 items grouped into 6 domains and 2 items representing an overall assessment. Items were assessed on a seven-point rating scale, and aggregate quality scores were calculated.
Aim: The aim of this study was to investigate 60 SNPs pertaining to drug metabolism and pharmacodynamics in the Burmese refugee population in the Fort Wayne, Indiana area to better inform patient care.
Materials & Methods: Sixty-two self-identified Burmese refugees were genotyped for 60 common SNPs pertaining to pharmacokinetic and pharmacodynamic pharmacogenes. The resulting allelic frequencies were compared with Ensembl's database for surrounding populations to Myanmar and America.
Despite advances in technology and guidelines from the Clinical Pharmacogenetics Implementation Consortium (CPIC) that focus on how to use pharmacogene test results, hurdles remain that have delayed the widespread application of pharmacogenomics in clinical practice. These hurdles include a lack of prospective randomized controlled trials to address the utility of pharmacogenomics on clinical outcomes, what the clinical algorithm for pharmacogenomics should be, and whether pharmacogenomics is cost-effective. However, the implementation of clinical practice guidelines, such as those from professional organizations, is commonplace and often termed the application of evidence-based medicine.

However, there are a paucity of studies that have determined the impact of functional group modifications in the synthetic cathinone chemical structures on plasma and central nervous system (CNS) pharmacokinetics. In the present study, we investigated the in vivo plasma and CNS pharmacokinetics of three synthetic cathinones whose structures differ by lengthening of the α-alkyl chain: methylone (-CH), butylone (-CHCH), and pentylone (-CHCHCH).

A review of the pharmacogenetics (PGt) and pathophysiology of calcium voltage-gated channel subunit alpha1 S (CACNA1S) mutations in malignant hyperthermia susceptibility type 5 (MHS5; MIM #60188) is presented. Malignant hyperthermia (MH) is a life-threatening hypermetabolic state of skeletal muscle usually induced by volatile, halogenated anesthetics and/or the depolarizing neuromuscular blocker succinylcholine. In addition to ryanodine receptor 1 (RYR1) mutations, several CACNA1S mutations are known to be risk factors for increased susceptibility to MH (MHS).
