A Modified Potency Test Strategy For Iv Admixtures Prepared By Robotic Systems, Fang Zhao, Vivek S. Dave, Susan E. Hughes

Pharmacy Faculty/Staff Publications

Introduction:

Robotic systems are increasingly used for compounding sterile IV admixtures (1-5). In addition to routine gravimetric checks, initial and periodic drug potency analysis by high-performance liquid chromatography (HPLC) is desired to verify the system accuracy. However, the conventional HPLC test procedures often result in unexpected failures (1-2).

This study was initiated to develop a modified HPLC test strategy to eliminate the common source of variability and focus the effort on the accuracy of robotic system.

Formulation And In Vivo Evaluation Of Aliskiren-Loaded Poly(Lactic-Co-Glycolic) Acid Nanoparticles, Derek E. Murrell, Jessica M. Coleman, Stacy D. Brown, Sam Harirforoosh

Pharmacy Faculty Articles and Research

Aliskiren (ALS) is a direct renin inhibitor with low bioavailability and high drug cost. The goal of this study was to increase the bioavailability of ALS through nanoformulation. The optimized formulation was then evaluated in spontaneously hypertensive rats (SHRs). We developed an ALS poly(lactic-co-glycolic) acid nanoparticle (ALS-NP) through the emulsion–diffusion–evaporation method with various solvents, stabilizer concentrations, and centrifugation speeds. SHRs were orally dosed with 30 mg/kg ALS or dose equivalent ALS-NP. Several parameters were assayed in plasma and/or urine at baseline and 24 h post-dose, while pharmacokinetic analysis included serial sampling. The optimum formulation was found with ethyl acetate, a …

Low And Moderate Prenatal Ethanol Exposure Of Mice During Gastrulation Or Neurulation Delays Neurobehavioral Development, Uta B. Schambra, Jeff Goldsmith, Kevin Nunley, Yali Liu, Sam Harirforoosh, Heidi M. Schambra

Pharmacy Faculty Articles and Research

Human and animal studies show significant delays in neurobehavioral development in offspring after prolonged prenatal exposure to moderate and high ethanol doses resulting in high blood alcohol concentration (BECs). However, none have investigated the effects of lower ethanol doses given acutely during specific developmental time periods. Here, we sought to create a mouse model for modest and circumscribed human drinking during the 3rd and 4th weeks of pregnancy.

We acutely treated mice during embryo gastrulation on gestational day (GD) 7 or neurulation on GD8 with a low or moderate ethanol dose given via gavage that resulted in BECs of 107 …

Molecular Overlap In The Regulation Of Sk Channels By Small Molecules And Phosphoinositides, Miao Zhang, Xuan-Yu Meng, Ji-Fang Zhang, Meng Cui, Diomedes E. Logothetis

Pharmacy Faculty Articles and Research

Phosphatidylinositol 4,5-bisphosphate (PIP2) directly interacts with the small-conductance Ca2+-activated K+ 2-a (SK2-a) channel/calmodulin complex, serving as a critical element in the regulation of channel activity. We report that changes of protein conformation in close proximity to the PIP2 binding site induced by a small-molecule SK channel modulator, NS309, can effectively enhance the interaction between the protein and PIP2 to potentiate channel activity. This novel modulation of PIP2 sensitivity by small-molecule drugs is likely not to be limited in its application to SK channels, representing an intriguing strategy to develop drugs controlling the activity of the large number of PIP2-dependent proteins.

The Role Of Community Pharmacy-Based Vaccination In The Usa: Current Practice And Future Directions, Albert Bach, Jeffery A. Goad

Pharmacy Faculty Articles and Research

Community pharmacy-based provision of immunizations in the USA has become commonplace in the last few decades, with success in increasing rates of immunizations. Community pharmacy-based vaccination services are provided by pharmacists educated in the practice of immunization delivery and provide a convenient and accessible option for receiving immunizations. The pharmacist's role in immunization practice has been described as serving in the roles of educator, facilitator, and immunizer. With a majority of pharmacist-provided vaccinations occurring in the community pharmacy setting, there are many examples of community pharmacists serving in these immunization roles with successful outcomes. Different community pharmacies employ a number …

Nanoformulation For Anticancer Drug Delivery: Enhanced Pharmacokinetics And Circulation, Gaurav Parekh

Doctoral Dissertations

In this study, we have explored the application of the Layer-by-Layer (LbL) assembly technique for improving injectable drug delivery systems of low soluble anticancer drugs (e.g. Camptothecin (CPT), Paclitaxel (PTX) or Doxorubicin (DOX)). For this study, a polyelectrolyte shell encapsulates different types of drug nanocores (e.g. soft core, nanomicelle or solid lipid nanocores).The low soluble drugs tend to crystallize and precipitate in an aqueous medium. This is the reason they cannot be injected and may have low concentrations and low circulation time in the blood. Even though these drugs when present in the cancer microenvironment have high anti-tumor inhibition, the …

Intractable Delay And The Need To Amend The Petition Provisions Of The Fdca, Diana R. H. Winters

Indiana Law Journal

Private party oversight has proven to be ineffective at countering inaction by the Food and Drug Administration (FDA). Inaction when regulation is warranted can put the public at continued and increasing risk of harm, but the failure of private enforcement to compel action reverberates beyond this harm to the interests of individuals. It also diminishes the transparency of agency decision making, lessens the opportunity for public participation, and reduces the interaction between the institutions that oversee agencies. Moreover, the benefits afforded to the administrative process by judicial review are weakened.

This Article analyzes two examples of FDA inertia and compares …

AIMS: To find methods for potent drug development by targeting to biocomplex with high copy number.

METHODS: Phi29 DNA packaging motor components with different stoichiometries were used as model to assay virion assembly with Yang Hui's Triangle [Formula: see text], where Z = stoichiometry, M = drugged subunits per biocomplex, p and q are the fraction of drugged and undrugged subunits in the population.

RESULTS: Inhibition efficiency follows a power function. When number of drugged subunits to block the function of the complex K = 1, the uninhibited biocomplex equals q(z), demonstrating the multiplicative effect of stoichiometry on inhibition with …

Influence Of Linker Length And Composition On Enzymatic Activity And Ribosomal Binding Of Neomycin Dimers, Derrick Watkins, Sunil Kumar, Keith D. Green, Dev P. Arya, Sylvie Garneau-Tsodikova

Pharmaceutical Sciences Faculty Publications

The human and bacterial A site rRNA binding as well as the aminoglycoside-modifying enzyme (AME) activity against a series of neomycin B (NEO) dimers is presented. The data indicate that by simple modifications of linker length and composition, substantial differences in rRNA selectivity and AME activity can be obtained. We tested five different AMEs with dimeric NEO dimers that were tethered via triazole, urea, and thiourea linkages. We show that triazole-linked dimers were the worst substrates for most AMEs, with those containing the longer linkers showing the largest decrease in activity. Thiourea-linked dimers that showed a decrease in activity by …

Inhibition Of Aminoglycoside Acetyltransferase Resistance Enzymes By Metal Salts, Yijia Li, Keith D. Green, Brooke R. Johnson, Sylvie Garneau-Tsodikova

Pharmaceutical Sciences Faculty Publications

Aminoglycosides (AGs) are clinically relevant antibiotics used to treat infections caused by both Gram-negative and Gram-positive bacteria, as well as Mycobacteria. As with all current antibacterial agents, resistance to AGs is an increasing problem. The most common mechanism of resistance to AGs is the presence of AG-modifying enzymes (AMEs) in bacterial cells, with AG acetyltransferases (AACs) being the most prevalent. Recently, it was discovered that Zn²⁺ metal ions displayed an inhibitory effect on the resistance enzyme AAC(6')-Ib in Acinetobacter baumannii and Escherichia coli. In this study, we explore a wide array of metal salts (Mg²⁺, …

Research Proposal: Emrs Changing Patient Medication Errors, Kerry Moore

Applied Research Projects

In 2009 the federal government initiated the American Recovery and Reinvestment Act (ARRA) in efforts to improve timely and quality health care. This new initiative promised to provide great incentives to health care providers who took advantage of the program by implementing electronic medical records (EMRs) within their facilities, clinics, and practices. Coupled with tight deadlines and the incentive of reimbursement, the health care world has been witness to an influx of EMRs being developed by vendors and implemented at health care facilities. The rate at which these EMRs have been implemented has been astounding. So fast, the health care …

Department of Psychology: Faculty Publications

The present study investigated the validity of a novel pup-based repeated elevated plus maze task to detect reduced anxiety and increased maternal responsiveness in postpartum female rats and explored the roles of dopamine D2, serotonin transporter and GABA/benzodiazepine receptors in the mediation of these processes. Sprague–Dawley postpartum or nulliparous female rats were tested 4 times every other day on postpartum days 4, 6 and 8 in an elevated plus maze with 4 pups or 4 pup-size erasers placed on each end of the two open arms. When tested with erasers, untreated postpartum mother rats entered the open arms proportionally more …

Examining Pharmacy Students’ Perceptions Of Clinical Faculty Mentoring Characteristics Influencing Students’ Decision To Pursue A Pharmacy Residency, Kin S. Ly

All Theses And Dissertations

The field of pharmacy is changing from a drug-distribution-centered model to a patient-centered integrated model whereby pharmacists are actively involved in patient care as part of an interdisciplinary team. To address the estimated pharmacy leadership crisis in the future and to prepare pharmacists to work in the changing healthcare landscape, national pharmacy organizations such as the American Society of Health-System Pharmacists (ASHP) and the American College of Clinical Pharmacy (ACCP) have stated that postgraduate pharmacy residency should be mandatory by 2020. Past pharmacy research literature has shown that while many factors influence students to pursue a pharmacy residency, there is …

In Silico Molecular Docking Analysis To Predict The Role Of Metal Ions In The Function Of Drug Targeted Proteins, S. M. A. Shahid, Qazi M. S. Jamal, J. M. Arif, Fahad M. Al-Khodairy, Anupam Dhasmana, Mohtashim Lohani

School of Medicine Publications

Metal ions are required for many critical functions in living systems. Scarcity of some metal ions can lead to disease. A characteristic of metals is that they easily lose electrons from the familiar elemental or metallic state to form positively charged ions which tend to be soluble in biological fluids. Role of zinc, calcium and copper ions in the catalytic mechanism of drug targeted proteins such as Farnesyltransferase, Neuraminidase and Thioredoxin are analyzed using molecular docking, respectively. The docking results show that inhibitors have low Binding, docking and internal energies with proteins in the presence of Zn, Ca and Cu …
