Pharmaceutical Sciences and Research

Ropinirole HCl is a non-ergoline dopamine agonist which is recommended for the treatment of both Parkinson’s disease and Restless Legs Syndrome (RLS). Its half-life is about 6 hours and it is metabolized in the liver primarily by CYP1A2. Its metabolites are water-soluble and rapidly excreted from the body in urine. However, its oral bioavailability is low. Therefore, this current project aimed to produce and evaluate sustained release ropinirole microparticles coated with Eudragit^® RS 100 and RL 100 by varying polymer types and concentrations. Ropinirole microparticles were prepared by oil in oil emulsion solvent evaporation technique. Emulsifier concentration was constantly …

Nanoformulations Of Essential Oils Extracted From Pistacia Lentiscus And Boswellia Sacra And Investigation Of Their Anticancer, Antimicrobial, And Antioxidant Activities., Obaydah Abd Alkader Alabrahim

Theses and Dissertations

Essential oils (EOs) obtained from natural sources have shown promising biological and therapeutical properties such as anticancer, antimicrobial, and antioxidant activities, attributing to their high content of a variety of bioactive components. However, EOs’ therapeutic properties are limited by their low stability, poor bioavailability, high volatility, and low targeting ability. Therefore, the encapsulation and nanoformulation of EOs can maximize their therapeutical efficiency and physicochemical properties while overcoming their undesirable side effects and drawbacks. EOs extracted from the resins of Pistacia Lentiscus var. Chia (P.oil) and Boswellia Sacra (B.oil) are two promising EOs that have shown great therapeutic potential. P.oil was …

The Opioid Epidemic: How Genetics Play A Role In Addiction And Treatment, Kirsten Houston

Honors College Theses

The opioid epidemic is an issue within the pharmaceutical industry in the United States of America due to prescription and non-prescription substances being made available to the population. Opioids include chemical substances that affect the body and brain through opioid receptors, including the mu, kappa, and delta receptors. These substances are derived and synthesized from the poppy plant. Multiple causes have been linked to opioid abuse disorder, including but not limited to employment, income, housing, nutrition, mental health disorders, and genetics. By gathering information from previous literature, genetics may be the main cause of narcotic analgesic tolerance and abuse. Specific …

Solid Dispersion Technology For Improving The Solubility Of Antiviral Drugs, Maria Elvina Tresia Butar-Butar, Nasrul Wathoni, Hestiary Ratih, Yoga Windhu Wardhana

Pharmaceutical Sciences and Research

Most drugs, including antiviral drugs, show low solubility in water, which affects dissolution, bioavailability, and therapeutic effectiveness. Therefore, many antiviral drugs are given in very large doses. One of the efforts to overcome these problems is the application of solid dispersions in which polymers and surfactants can trap drug molecules that are in the amorphous phase. Drugs in a hydrophilic carrier will increase wettability, water absorption capacity, and porosity of particles, so that the drug is released better. This review article will discuss the development of technology in solid-state, how solid dispersion overcomes the lack of solubility and the rate …

Natural products (NPs) have been used for treating diseases and infections for thousands of years and represent a valuable resource for drug discovery when combined with …

A Ligand-Based Approach To Identifying Commercially Available Inhibitors Of Human Galactokinase (Galk), Tyler Rose

Annual Research Symposium

The purpose of this project was to find inhibitors of the human galactokinase (GALK) enzyme. GALK is responsible for catalyzing the conversion of galactose to galactose 1-phosphate, the first step in galactose metabolism. Galactose 1-phosphate builds up in the cells of patients with type 1 galactosemia due a genetic disorder. It has been proposed that inhibiting galactose 1-phosphate production by GALK may prevent many of the major complications of type 1 galactosemia. In this study, a ligand-based approach was used to identify commercially available inhibitors of GALK, starting from galactose-bearing natural products. Candidate inhibitors were screened for their ability to …

Testing The Efficacy And Synergistic Components Of Sesamol And Black Rice Extract On Human Colon Cancer Cells, Sera Lim, Philip M. Gerk

Undergraduate Research Posters

Purpose: Systemic treatment of colorectal cancer involves chemotherapeutic agents which elicit serious and negative side effects from the toxicity of the drug. To address this issue, we are testing dietary supplements for their efficacy against human colon cancer cell lines and also their potential synergistic effects when combined with conventional chemotherapy. Dietary supplements (specifically sesamol and black rice extract) exhibit anticancer, anti-inflammatory, and chemo-preventive properties. Meanwhile, one of the cancer resistance mechanisms is the upregulation of drug elimination mechanisms, leading to multi-drug resistance. We hypothesize that dietary compounds will act as chemo-enhancers, thus enhancing potency of the chemotherapy drug(s) on …

Association Of Environmental Pollutants Exposure With Pulmonary Fibrosis: A Mini Review Of Molecular Mechanism Mediated, Soni Siswanto, Bantari W.K. Wardhani

Pharmaceutical Sciences and Research

Pulmonary fibrosis is a specific form of chronic progressive interstitial lung disease. Deposition of extracellular matrix, mainly collagen, is the pathogenic characteristic of pulmonary fibrosis. Many reports show that environmental pollutants, particularly asbestos, silica, mercury, cadmium, and benzo(a)pyrene, are contributed in the etiology of lung injury and a risk factor in the development of idiopathic pulmonary fibrosis (IPF) in humans. Based on its physicochemical properties, environmental pollutant-induced pulmonary fibrosis can be developed after a particular type or dose of exposure. To date, some studies have focused on variant pollutants that are induced. However, the molecular mechanism of various pollutants to …

Studies Toward The Development Of An Improved Countermeasure For Synthetic Opioid Overdose, Sidnee L. Hedrick

Theses and Dissertations--Pharmacy

One of the most prominent opioid analgesics in the United States is the high potency agonist fentanyl. It is used in the treatment of acute and chronic pain and as an anesthetic adjuvant. When used inappropriately, however, ingestion of just a few milligrams of fentanyl or other synthetic opioid can cause opioid-induced respiratory depression (OIRD), often leading to death. Currently, the treatment of choice for OIRD is the opioid receptor antagonist naloxone. Recent reports, however, suggest that higher doses or repeated dosing of naloxone (due to recurrence of respiratory depression) may be required to fully reverse fentanyl-induced respiratory depression, rendering …

The Benefits Of Astaxanthin To Improve Pain Relief In Patients With Painful Diabetic Neuropathy: An Open-Label, Randomized Controlled Trial, Rizaldy Taslim Pinzon, Mary Rose Angelina Budi Harsana

Pharmaceutical Sciences and Research

Treatment of diabetic neuropathy is still carried out by providing symptomatic therapy, which only improves ± 50% of the total symptoms felt by patients, but does not tackle the underlying causes of the disease.
