Non-Genomic Effects Of Glucocorticoids: An Updated View, Reynod A. Panettieri, Dedmer Schaafsma, Yassine Amrani, Cynthia Koziol-White, Rennolds S. Ostrom, Omar Tliba

Pharmacy Faculty Articles and Research

Glucocorticoid (GC) anti-inflammatory effects generally require a prolonged onset of action and involve genomic processes. Because of the rapidity of some of the GC effects, however, the concept that non-genomic actions may contribute to GC mechanisms of action has arisen. While the mechanisms have not been completely elucidated, the non-genomic effects may play a role in the management of inflammatory diseases. For instance, we recently reported that GCs ‘rapidly’ enhanced the effects of bronchodilators, agents used in the treatment of allergic asthma. In this review article, we discuss (i) the non-genomic effects of GCs on pathways relevant to the pathogenesis …

Prescription And Over-The-Counter Medication Record Integration: A Holistic Patient-Centered Approach, Clark D. Kebodeaux

Pharmacy Practice and Science Faculty Publications

Objective: Nonprescription or over-the-counter (OTC) medications play a crucial role in a patient’s ability to make choices to manage his or her own health care. Often these nonprescription choices are unknown to health care practitioners and thus are often not included as part of patients’ health records. The exclusion of these therapies can pose risks to patient safety. There is a significant need to address the capture of OTC medication use in both the physician and pharmacy electronic health records (EHRs) and during the practitionerepatient medication history and reconciliation process.

Blocking Drug Activation As A Therapeutic Strategy To Attenuate Acute Toxicity And Physiological Effects Of Heroin, Ting Zhang, Xirong Zheng, Kyungbo Kim, Fang Zheng, Chang-Guo Zhan

Molecular Modeling and Biopharmaceutical Center Faculty Publications

Heroin is a growing national crisis in America. There is an increasing frequency of heroin overdoses. All of the currently used therapeutic approaches to treatment of heroin abuse and other opioid drugs of abuse focus on antagonizing a brain receptor (particularly µ-opiate receptors). However, it has been known that the therapeutic use of certain µ-opiate receptor antagonist may actually increase heroin overdose. Once overdosed, heroin addicts may continue to get overdosed again and again until fatal. Here we report our design and validation of a novel therapeutic strategy targeting heroin activation based on our analysis of the chemical transformation and …

School of Pharmacy Faculty Articles

Action potentials (APs) are the functional units of fast electrical signaling in excitable cells. The upstroke and downstroke of an AP is generated by the competing and asynchronous action of Na+- and K+-selective voltage-gated conductances. Although a mixture of voltage-gated channels has been long recognized to contribute to the generation and temporal characteristics of the AP, understanding how each of these proteins function and are regulated during electrical signaling remains the subject of intense research. AP properties vary among different cellular types because of the expression diversity, subcellular location, and modulation of ion channels. These complexities, in addition to the …

Nadolol In Pregnancy: A Medical Student’S Reflection On Her Pregnancy, Rebecca King-Mallory, Shawndra Barker, Kaitlin Mcgrogan, Adam M. Franks

Marshall Journal of Medicine

Hypertension is a common concern during pregnancy. Beta-blockers are one potential treatment, but third trimester exposure has correlated with an increased risk of perinatal events. Nadolol, a nonselective beta blocker, has properties that differ from those of its selective counterparts, including longer half-life, decreased protein binding, and renal excretion in the unchanged form. There is very limited data on the use of nadolol during pregnancy, and its safety has not been completely evaluated. This case study documents the perinatal outcomes of nadolol use throughout a medical student’s pregnancy and explores the experience in obtaining and undergoing medical care.
