Structure-Activity Relationships and Drug Design01:28

Structure-Activity Relationships and Drug Design

957
Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence...

Drug Discovery: Overview

8.3K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Analysis of Population Pharmacokinetic Data01:12

Analysis of Population Pharmacokinetic Data

348
Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

Pharmacovigilance01:19

Pharmacovigilance

959
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Prescription, Nonprescription and Orphan Drugs01:02

Prescription, Nonprescription and Orphan Drugs

828
Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

157
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Area of Science:

  • Pharmacology
  • Biomedical Informatics
  • Drug Discovery

Background:

  • Drug repurposing offers advantages over de novo drug discovery.
  • Real-world evidence (RWE) is increasingly important for regulatory drug approvals.
  • Real-world data (RWD) provides a valuable resource for drug repurposing initiatives.

Purpose of the Study:

  • To characterize studies utilizing real-world data for drug repurposing.
  • To identify and discuss challenges and potential solutions in RWD-based drug repurposing.
  • To provide insights for advancing the use of RWD in pharmaceutical research.

Main Methods:

  • A comprehensive scoping review was conducted.
  • Studies using real-world data for drug repurposing were systematically identified and analyzed.
  • Inclusion criteria were applied to a large dataset of relevant research.

Main Results:

  • A total of 250 studies met the inclusion criteria.
  • 36 studies focused on hypothesis generation using RWD.
  • 101 studies were dedicated to hypothesis validation, and 7 to safety assessment.

Conclusions:

  • Key challenges include fragmented data sources, poor clinical granularity, and data mining-induced false positives.
  • Bias and confounding in hypothesis validation require careful management.
  • Lack of clear regulatory guidance hinders the advancement of RWD-driven drug repurposing.
