Study Objective: Numerous medications interact at serotonin (5-hydroxytryptamine [5-HT]) receptors directly or through off-target interactions, causing mild to severe serotonergic adverse drug events (ADEs), particularly among older adults. Our objective was to develop a novel molecular-based toxicity scoring system to assess serotonergic burden resulting from concurrently administered drugs. Quantitative methods to assess serotonergic burden may provide a useful clinical tool for improving pharmacotherapy.

Study Objective: Serotonergic adverse drug events (ADEs) are caused by enhanced intrasynaptic concentrations of 5-hydroxytryptamine (5-HT). No systematic process currently exists for evaluating cumulative 5-HT and off-target toxicity of serotonergic drugs. The primary study aim was to create a Serotonergic Expanded Bioactivity Matrix (SEBM) by using a molecular bioinformatics, polypharmacologic approach for assessment of the participation of individual 5-HT drugs in serotonin syndrome (SS) reports.

In 2009 the U.S. Food and Drug Administration (FDA) placed a black box warning on metoclopramide (MCP) due to the increased risks and prevalence of tardive dyskinesia (TD).

Background: Anticholinergic (AC) adverse drug events (ADEs) are caused by inhibition of muscarinic receptors as a result of designated or off-target drug-receptor interactions. In practice, AC toxicity is assessed primarily based on clinician experience. The goal of this study was to evaluate a novel concept of integrating big pharmacological and healthcare data to assess clinical AC toxicity risks.

Background: It has been estimated that more than $8 billion is spent annually on the management of breast cancer in the United States. The taxane chemotherapeutic agents are cornerstones in the treatment of breast cancer, yet no study has assessed whether the choice of a taxane affects the economic outcomes of metastatic breast cancer treatment.

Objective: To determine if differences exist in the medical cost of care in patients receiving taxane-based chemotherapy for metastatic breast cancer, and to compare the use of ancillary medications (for neutropenia, anemia, and nausea and vomiting) and their associated costs among taxanes.

Background: In late 2007, the Food and Drug Administration (FDA) held public hearings exploring the establishment of a new behind-the-counter (BTC) drug program. However, little is known about the views of pharmacists regarding such a program.

Objective: To assess the overall perceptions of Idaho's practicing pharmacists about the creation of a formal BTC drug program, the appropriateness of including certain drug categories, specific barriers to its adoption, and the impact of the new program on access to medicines.

Objectives: To evaluate early predictors of advanced pharmacy practice experience (APPE) performance using either timed pharmaceutical care plan (TPCP) reports of 4 case histories or traditional lecture-based pharmacotherapy course examinations.

Methods: Statistical process control (SPC) methods were used to identify a group of third-year pharmacy students "at risk" for poor APPE performance (defined as an APPE grade point average of < 3.0).

Objective: To estimate frequencies of potential errors involving similarly named drugs using a retrospective claims database and measure the association between frequencies of potential errors and two measures of drug name similarity, edit distance (minimum number of insertions, substitutions, or deletions of characters required to change a given word into another target word) and normalized edit distance (proportion of letters that must be changed to commute one word to another, and ranges from 0 to 1, with 0 indicating identical words, and 1 indicating a pair of words with no common letters).

Design: Retrospective database analysis.

Setting: Idaho Medicaid claims data from 1993 to 2000.

Background: Assimilation of vitamin B(12) from dietary sources requires gastric acid. By decreasing acid production, the proton pump inhibitors (PPIs) and histamine(2) (H(2))-blockers may reduce vitamin B(12) absorption.

Objective: To determine whether chronic acid suppression therapy is associated with the initiation of vitamin B(12) supplementation, we conducted a retrospective case-control study using a state-wide Medicaid population.
