Review On Drug Delivery Applications Of Ethosomes: Current Developments And Prospects, Mayuri Shitole, Sopan Nangare, Udaykumar Patil, Namdeo R. Jadhav

The Thai Journal of Pharmaceutical Sciences

Transdermal drug delivery system networks are primarily affected by poor penetration of therapeutically active compounds. The stratum corneum (SC) is the foremost barrier of the skin, which restricts the permeation of the drug molecule. In this context, to date, numerous approaches have been implemented to overcome the SC barrier limitations. Out of this, few advanced approaches including liposomes, niosomes, ethosomes, and transferosomes are majorly used to boost the permeation of drug and cosmetic agents across the SC barrier. Among these vesicles, ethosomes are stand out as the best substitute for topical drug delivery. In a nutshell, ethosomes are the elastic …

Poststroke Seizure And Epilepsy: A Review Of Incidence, Risk Factors, Diagnosis, Pathophysiology, And Pharmacological Therapies, Joseph Phan, Mario Ramos, Theodore Soares, Mayur S. Parmar

HPD Articles

Stroke is the most common cause of epilepsy and ultimately leads to a decrease in the quality of life of those affected. Ischemic and hemorrhagic strokes can both lead to poststroke epilepsy (PSE). Significant risk factors for PSE include age < 65age less than 65 years, stroke severity measured by the National Institutes of Health Stroke Scale (NIHSS), cortical involvement, and genetic factors such as TRPM6 polymorphism. The diagnosis of PSE is made by using imaging modalities, blood biomarkers, and prognostic criteria. Electroencephalography (EEG) is currently the gold standard to diagnose PSE, while new combinations of modalities are being tested to increase diagnostic specificity. This literature review uncovers a newly found mechanism for the pathology of poststroke epilepsy. The pathogenesis of early-onset and late-onset is characterized by sequelae of neuronal cellular hypoxia and disruption of the blood-brain barrier, respectively. Interleukin-6 is responsible for increasing the activity of glial cells, causing gliosis and hyperexcitability of neurons. Epinephrine, high-mobility group protein B1, downregulation of CD32, and upregulation of HLA-DR impact the pathology of poststroke epilepsy by inhibiting the normal neuronal immune response. Decreased levels of neuropeptide Y, a neurotransmitter, act through multiple unique mechanisms, such as inhibiting intracellular Ca accumulation and acting as an anti-inflammatory, also implemented in the worsening progression of poststroke epilepsy. Additionally, CA1 hippocampal resonant neurons that increase theta oscillation are associated with poststroke epilepsy. Hypertensive small vessel disease may also have an implication in the temporal lobe epilepsy by causing occult microinfarctions. Furthermore, this review highlights the potential use of statins as primary prophylaxis against PSE, with multiple studies demonstrating a reduction in incidence using statins alone, statins in combination with antiepileptic drugs (AEDs), and statins with aspirin. The evidence strongly suggests that the second generation AEDs are a superior treatment method for PSE. Data from numerous studies demonstrate their relative lack of significant drug interactions, increased tolerability, and potential superiority in maintaining seizure-free status.

The Effects Of Gestational Exposure To Buprenorphine Or Morphine On Offspring Development, Abigail Myers

Wayne State University Theses

The opioid crisis in the United States has grown to epidemic proportions with opioid dependence among pregnant women quadrupling from 1999-2014. Opioid-dependent pregnant women are commonly given opioid maintenance therapies (e.g., buprenorphine), but the developmental and neurological effects of these drugs on offspring development are poorly understood. Our study uses a translational rodent model to characterize the developmental consequences of gestational morphine (“MS”; mimicking opioid use disorder) or buprenorphine (“BUP”; mimicking opioid maintenance therapy) exposure on exposed offspring. Female rats started BUP (1.0 mg/kg) or MS (3-6.0 mg/kg) exposure 7 days before pregnancy to represent an established user and either …

Building Tools For Improved Modulation Of The Human Gabaa Receptor, A Central Nervous System Target For The Treatment Of Anxiety, Garrett Edward Zinck

Theses and Dissertations--Pharmacy

In the U.S., anxiety is recognized as an increasing range of mentally and physically debilitating psychiatric health disorders with significant economic repercussions. Over the last 20 years, several novel anti-anxiety therapies have entered the drug development pipeline, but none have made it to market.

The work in this dissertation focused on structurally modifying valerenic acid (VA), a structurally unique carboxylated sesquiterpene acid found in Valeriana officinalis. VA is putatively reported to have allosteric modulatory activity of the human GABA_A receptor, a ligand-gated ion channel responsible for attenuating neurotransmissions. Structural modeling of VA’s GABA_A receptor interaction suggests that …

Response Of Dopaminergic System To Cocaine Exposure, Recovery After Cocaine Abstinence, And Impact Of A Long-Acting Cocaine Hydrolase, Jing Deng

Theses and Dissertations--Pharmacy

Cocaine produces its physiological effects by targeting multiple proteins in the central nervous system, particularly by binding with dopamine transporter (DAT) to block the normal dopamine (DA) recycling process. This process along with the pleasure feeling would wear off shortly after the abstinence from the drug. However, chronic cocaine use is associated with neuroadaptations in the dopaminergic system, including increases in the density of DAT on plasma membrane of dopaminergic neurons. Given the critical role of DAT in neurotransmission, various studies have been carried out on animal models to learn its structure, function, and distribution. Long-standing evidence supports that DAT …

Evaluating The Effects Of Mechlorethamine On The Dermal-Epidermal Junction, Trishaal Janardhanam Raghavendra Rao

Theses and Dissertations

Sulfur Mustard (SM) is a chemical warfare agent first utilized on the battlefield more than 100 years ago. To the present time, no antidote to combat the dermatotoxicity of SM exists. Mechlorethamine (HN2) is a derivative of SM which is used in anticancer therapy. Dermal exposure of HN2 is associated with dermal-epidermal junction (DEJ) disruption (vesication) which limits its clinical usefulness. The primary purpose of the present study was to investigate the mechanisms of vesication caused by HN2 using an in vivo mouse ear vesicant model (MEVM). The ears of male or female C57BL/ 6J mice were exposed to a …
