Drug toxicity: Drug–Drug Interaction01:30

Drug toxicity: Drug–Drug Interaction

379
Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...

Pharmacokinetics: Drug–Drug Interactions

753
Drug interactions occur when the pharmacological effect of one drug is altered by another substance, either enhancing or diminishing its activity. The drug whose activity is altered is known as the object drug, and the substance causing the alteration is called the agent drug or the precipitant. The net effects of these interactions are mostly undesirable, leading to decreased effectiveness or increased adverse effects. In rare cases, interactions can be beneficial, such as the enhanced...

Pharmacovigilance01:19

Pharmacovigilance

2.0K
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...

Drug-Receptor Interactions01:29

Drug-Receptor Interactions

8.5K
Drug-receptor interaction describes the binding of receptors by drugs, but not all drug-receptor interactions result in activation and tissue response. For instance, the binding of agonists activates the receptor to generate a cellular reaction, while antagonists bind to receptors without causing their activation.
Several parameters, such as the drug's affinity for its receptor and its efficacy, which is its ability to activate the receptor, determine the drug's effect on the tissue....

Pharmacokinetics: Drug–Food and Drug–Viral Interactions01:26

Pharmacokinetics: Drug–Food and Drug–Viral Interactions

629
A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of...

Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

213
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Summary

A common data model for drug-drug interactions is needed. Publicly available drug interaction data is highly inconsistent and lacks overlap, hindering standardization efforts.

Area of Science:

  • Pharmacology
  • Data Science
  • Bioinformatics

Background:

  • Standardizing drug-drug interaction (DDI) data is crucial for drug safety.
  • Existing public resources for DDI information are fragmented.

Purpose of the Study:

  • To assess the feasibility of a common data model for potential drug-drug interactions.
  • To identify data elements in publicly available DDI resources.

Main Methods:

  • Surveyed data elements from publicly accessible drug-drug interaction databases.
  • Analyzed the overlap and heterogeneity of information across these resources.

Main Results:

  • Found minimal overlap in data elements between different public DDI resources.
  • Observed significant heterogeneity in the information provided by these sources.

Conclusions:

  • Current public DDI data lacks standardization, posing challenges for creating a unified data model.
  • Further efforts are needed to harmonize DDI information for improved data integration and analysis.
