Clinical Pharmacogenetics Implementation Consortium Guideline (CPIC) for CYP2D6, ADRB1, ADRB2, ADRA2C, GRK4, and GRK5 Genotypes and Beta-Blocker Therapy.

Beta-blockers are widely used medications for a variety of indications, including heart failure, myocardial infarction, cardiac arrhythmias, and hypertension. Genetic variability in pharmacokinetic (e.g.

Implementation of CYP2C19 and CYP2D6 genotyping to guide antidepressant use in a large rural health system.

Purpose: We describe the implementation and ongoing maintenance of CYP2C19 and CYP2D6 focused pharmacogenetic (PGx) testing to guide antidepressant and antianxiety medication prescriptions in a large rural, nonprofit health system.

Summary: Depression and anxiety are common psychiatric conditions. Sanford Health implemented PGx testing for metabolism of cytochrome P450 (CYP) isozymes 2C19 and 2D6 in 2014 to inform prescribing for multiple medications, including antidepressant and antianxiety therapies.

Evolution of pharmacogenomic services and implementation of a multi-state pharmacogenomics clinic across a large rural healthcare system.

Pharmacogenomics (PGx) aims to maximize drug benefits while minimizing risk of toxicity. Although PGx has proven beneficial in many settings, clinical uptake lags. Lack of clinician confidence and limited availability of PGx testing can deter patients from completing PGx testing.

Patient satisfaction with return of pharmacogenomic results utilizing a patient portal message.

Returning pharmacogenomics (PGx) results to patients is complex and challenging. Patients prefer provider education; however, a gap in provider comfort in PGx results has been documented. This study's purpose was to evaluate satisfaction with the return of PGx test results using a patient portal message.

Metoprolol and : A Retrospective Cohort Study Evaluating Genotype-Based Outcomes.

Metoprolol is a medication commonly utilized in select patients to achieve a reduction in heart rate, systolic blood pressure, or other indications. A majority of metoprolol metabolism occurs via . Decreased expression of the CYP2D6 enzyme increases the concentration of metoprolol.

Cytochrome P450 2D6 Genotyping for Post-Operative Opioids.

Within most electronic medical records, automated decision support helps health care providers reduce the frequency of adverse drug reactions. Historically, this decision support has been used to prevent drug-drug interactions (DDIs). More recently, the clinical and scientific communities have been moving toward the use of this approach to predict and prevent drug-gene interactions (DGIs).

The effect of medication reconciliation on generating an accurate medication list in a pharmacogenomics practice.

Background: Medication reconciliation is recognized as a critically important medication safety element and a key initiative by multiple organizations. Within our precision medicine program, accurate medication lists are essential to our ability to make specific medication recommendations based on pharmacogenetic results. Our study aimed to identify discrepancies within the patient's medication list to improve medication management via genetic factors through a pharmacy team-based approach.

Implementing a pragmatic clinical trial to tailor opioids for acute pain on behalf of the IGNITE ADOPT PGx investigators.

Opioid prescribing for postoperative pain management is challenging because of inter-patient variability in opioid response and concern about opioid addiction. Tramadol, hydrocodone, and codeine depend on the cytochrome P450 2D6 (CYP2D6) enzyme for formation of highly potent metabolites. Individuals with reduced or absent CYP2D6 activity (i.

Progression of precision statin prescribing for reduction of statin-associated muscle symptoms.

Statins are among the most commonly prescribed medications, and improve patient outcomes by lowering cholesterol levels, but also have side effects. Variations in statin response can be attributed to a handful of factors that include pharmacogenetics. While not a true review article, this work was written using various search engines and terms and previous and newly published Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines for statins to provide a historical perspective in addition to the current status of statin-related pharmacogenetics and future perspectives.

SLCO1B1*5 Allele Is Associated With Atorvastatin Discontinuation and Adverse Muscle Symptoms in the Context of Routine Care.

The SLCO1B1 genotype is known to influence patient adherence to statin therapy, in part by increasing the risk for statin-associated musculoskeletal symptoms (SAMSs). The SLCO1B1*5 allele has previously been associated with simvastatin discontinuation and SAMSs. Prior analyses of the relationship between SLCO1B1*5 and atorvastatin muscle side effects have been inconclusive due to insufficient power.

Malignant hyperthermia susceptibility: utilization of genetic results in an electronic medical record to increase safety.

This manuscript describes implementation of clinical decision support for providers concerned with perioperative complications of malignant hyperthermia susceptibility. Clinical decision support for malignant hyperthermia susceptibility was implemented in 2018 based around our pre-emptive genotyping platform. We completed a brief descriptive review of patients who underwent pre-emptive testing, focused particularly on and genes.

genotype-guided antiplatelet therapy: promises and pitfalls.

Pharmacogenetic variants can alter the mechanism of action (pharmacodynamic gene variants) or kinetic processes such as absorption, distribution, metabolism and elimination (pharmacokinetic gene variants). Many initial successes in precision medicine occurred in the context of genes encoding the cytochromes P450 (CYP enzymes). CYP2C19 activates the antiplatelet drug clopidogrel, and polymorphisms in the gene are known to alter the outcome for patients taking clopidogrel in the context of cardiovascular disease.

Implementation of wide-scale pharmacogenetic testing in primary care.

The convergence of translational genomics and biomedical informatics has changed healthcare delivery. Institutional consortia have begun implementing lab testing and decision support for drug-gene interactions. Aggregate datasets are now revealing the impact of clinical decision support for drug-gene interactions.

Tadalafil: a phosphodiesterase-5 inhibitor for benign prostatic hyperplasia.

Tadalafil is a phosphodiesterase (PDE)-5 inhibitor recently approved by the United States Food and Drug Administration for lower urinary tracts symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). The mechanism for improved LUTS is thought to be related to three principal theories: alterations in nitric oxide levels, Rho-associated protein kinase deactivation, and reductions in pelvic atherosclerosis. The efficacy of PDE-5 inhibitors for the treatment of LUTS associated with BPH has been demonstrated in several randomized placebo-controlled trials.
