Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

269
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Hepatic Portal System01:21

Hepatic Portal System

5.7K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

224
Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

Hepatic Drug Excretion: Influencing Factors01:16

Hepatic Drug Excretion: Influencing Factors

562
The biliary system of the liver, crucial for bile secretion and drug excretion, comprises intrahepatic bile ducts that merge to form the common hepatic duct. This duct, carrying hepatic bile, combines with the cystic duct, draining the gallbladder and forming the common bile duct, which empties into the duodenum. Bile, produced by hepatic cells lining the bile canaliculi, is composed primarily of water, bile salts, pigments, electrolytes, and lesser amounts of cholesterol and fatty acids. Bile...

Hepatic Drug Clearance: Role of Transporters01:14

Hepatic Drug Clearance: Role of Transporters

306
In the liver and bile canaliculi, influx and efflux transporters modification can influence intrinsic clearance. Transporters play a significant role in moving drugs within liver cells. Elaborate models, such as the Biopharmaceutical Classification System (BCS), are essential to relate transporters to drug disposition. This system categorizes drugs into four classes based on solubility and permeability, providing insights into elimination routes and the effects of transporters following oral...

Area of Science:

  • Veterinary Medicine
  • Public Health
  • Infectious Diseases

Background:

  • Hepatitis E virus (HEV) is prevalent in swine populations globally.
  • HEV transmission from pigs to humans is increasing through direct contact, food, and blood transfusions.
  • While often asymptomatic in pigs, HEV can exacerbate other swine viral infections.

Purpose of the Study:

  • To outline effective strategies for controlling and preventing Hepatitis E virus (HEV) transmission.
  • To address the public health and veterinary challenges posed by HEV in swine.
  • To explore HEV control measures within the context of the One Health initiative.

Main Methods:

  • Review of current knowledge on HEV transmission routes and control measures.
  • Analysis of preventative strategies for food products, blood donations, and pork production.
  • Consideration of HEV implications in xenotransplantation and One Health approaches.

Main Results:

  • Blood donation screening effectively prevents transfusion-transmitted HEV.
  • Thorough cooking of meat and meat products mitigates foodborne HEV transmission.
  • Comprehensive herd management, including early weaning and biosecurity, can eliminate HEV from swine populations.

Conclusions:

  • Implementing a multi-faceted approach is crucial for controlling HEV.
  • Preventing HEV transmission aligns with the One Health concept, safeguarding both animal and human health.
  • Eliminating HEV from swine is essential to prevent zoonotic spillover and associated diseases.
