Drug Biotransformation: Overview01:16

Drug Biotransformation: Overview

3.8K
Pharmaceutical substances known as xenobiotics are predominantly lipophilic and nonionized. This enables them to permeate lipid bilayers, such as cell membranes, and interact with intracellular target receptors. Lipophilic drugs have an advantage in crossing biological barriers and reaching their intended sites of action. However, lipophilic drugs often have a restricted capacity for renal expulsion or elimination from the body. When these drugs enter the kidneys and undergo glomerular...

Drug Biotransformation: Overview

2.7K
Biotransformation, also known as drug metabolism, is a vital physiological process that chemically alters drugs, facilitating their elimination from the body and terminating their action. This process involves two main phases: phase I and phase II reactions. Phase I reactions, including oxidation, reduction, and hydrolysis, introduce or unmask polar functional groups on the drug molecule, thereby increasing its water solubility. By enhancing water solubility, the drug becomes more hydrophilic...

Factors Affecting Drug Biotransformation: Biological

608
Biological factors significantly impact drug metabolism, influencing drug clearance, efficacy, and potential toxicity.
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...

Factors Affecting Drug Biotransformation: Physicochemical and Chemical Properties of Drugs

761
A drug's physicochemical properties fundamentally influence its metabolism. For instance, a drug's molecular size and shape critically determine its interaction with enzymes and transporters — larger drugs may face difficulty reaching enzyme active sites, altering their metabolic pathways. The pKa of a drug, which establishes its ionization state, can impact its solubility and absorption, thereby influencing metabolism.
The drug's acidity or basicity is essential in...

Interpersonal Psychotherapy01:25

Interpersonal Psychotherapy

389
Interpersonal psychotherapy (IPT) is a structured, time-limited therapeutic approach initially developed to treat depression. It integrates key concepts from psychodynamic, humanistic, and cognitive-behavioral therapies, making it a uniquely eclectic framework. The therapy is rooted in the interpersonal theories of Adolph Meyer and Harry Stack Sullivan, as well as John Bowlby's attachment theory, and focuses on the interplay between interpersonal relationships and emotional well-being.

Understanding Interpersonal Attraction01:25

Understanding Interpersonal Attraction

307
Interpersonal attraction is a fundamental psychological phenomenon influencing human relationships across various contexts. It refers to one person's positive feelings or interests toward another, serving as the foundation for friendships, romantic partnerships, familial bonds, and professional relationships. The nature of interpersonal attraction extends beyond romantic connections, shaping interactions in both short-term and long-term social engagements.Psychological Foundations of...

Area of Science:

  • Microbiology
  • Pharmacology
  • Genomics

Background:

  • Individual drug responses vary due to factors like the gut microbiome.
  • Gut bacteria are known to metabolize drugs, but community-level effects are unclear.

Purpose of the Study:

  • To characterize drug biotransformation by diverse gut microbial communities.
  • To identify drugs with variable metabolism across human and animal microbiomes.
  • To develop predictive models for microbiota-mediated drug metabolism.

Main Methods:

  • Tested the metabolism of 271 drugs using 89 gut microbial communities.
  • Compared drug biotransformation across human and animal-derived microbiomes.
  • Developed and evaluated modeling approaches using metagenomic data.

Main Results:

  • Over 90% of tested drugs were metabolized by at least one microbiome.
  • Identified 66 drugs with highly variable metabolism in human microbiomes.
  • Observed significant differences in drug metabolism between human and animal microbiomes.

Conclusions:

  • Gut microbiome composition profoundly influences drug metabolism and variability.
  • Predictive models can aid in understanding and managing microbiome-drug interactions.
  • Findings support integrating microbiome data into drug discovery and personalized medicine.
