Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

1.4K
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Drug Dosage Regimen: Overview

4.1K
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

Dosage Regimen: Fixed Dose

2.3K
Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

755
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Drug Delivery: Miscellaneous Routes

1.1K
Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection,  and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs...

Pharmaceutical Poisoning: Treatment Strategies

279
Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...

Area of Science:

  • Microbiology
  • Cardiovascular Science
  • Metabolomics

Background:

  • Microbial metabolism of dietary components is a known factor in cardiovascular disease (CVD) and atherosclerosis.
  • Specific microbial metabolites, such as trimethylamines, are implicated as pro-atherogenic.

Purpose of the Study:

  • To investigate the role of microbial TMA lyases in the production of trimethylamines.
  • To determine if inhibiting microbial TMA lyases can prevent atherosclerosis in vivo.

Main Methods:

  • Utilized genetic and pharmacological approaches to inhibit microbial TMA lyases.
  • Assessed atherosclerosis development in animal models following TMA lyase inhibition.
  • Measured trimethylamine levels and other relevant biomarkers.

Main Results:

  • Demonstrated that inhibition of microbial TMA lyases significantly reduces trimethylamine production.
  • Showcased a marked prevention of atherosclerosis in vivo upon TMA lyase inhibition.
  • Confirmed the causal link between microbial TMA production and atherosclerosis progression.

Conclusions:

  • Microbial TMA lyases are critical for generating pro-atherogenic trimethylamines from dietary sources.
  • Inhibition of microbial TMA lyases represents a potential therapeutic strategy for preventing atherosclerosis.
