Drug-Drug Interactions

The Drug-Drug Interactions API provides information to determine the effect of a drug or a metabolite on another drug's pharmacokinetic or pharmacodynamic profile.

It comprises a set of drug-drug interaction records supported by evidence from regulatory authorities and literature. Drug records for the general information on a drug and detailed reference records are also included. Four taxonomies to build drug queries are dedicated to this API: TherapeuticGroup, ProductCategory, MolecularMechanism and AdmeMechanism.

There are 3 types of drug-drug interactions:

  • Pharmacokinetic interaction, with or without toxic / efficacy effects, results in a different PK profile (ADME) of the evaluated drug when administered in combination with one or more interaction molecule(s)
  • Pharmacodynamic interaction results in an additive or antagonistic effect of a drug or a metabolite (interaction molecule(s)) with another drug (evaluated drug) causing an increased or decreased pharmacological toxicological outcome
  • Metabolic interaction is a combination of PK and PD interactions

Each drug-drug interaction contains at least one associated interaction study. Each interaction study is defined as a drug-drug interaction in a given experimental condition and population. It is also associated with a given reference, model, outcome, potential adverse event(s) and risk. Drug-drug interaction drugs are those from the Drug Design API having at least one interaction study.

Drug-Drug Interactions API can help you to

  • Understand which drug-drug interactions exist for existing products in order to design better in-house products and ultimately develop better clinical candidates
  • Understand a drug's pharmacokinetic exposure and pharmacodynamics interference
  • Optimize the ADME profile and effectiveness of drug candidates
  • Perform quantitative analysis of interactions between drugs and patients using appropriate models
  • Design clinical trials and understand drug prescription while considering that drug interactions may:
    • Decrease one or both drugs' effectiveness – resulting in insufficient therapy, sometimes creating unnecessary costs and complications
    • Lead to adverse events / toxicity due to increased exposure or synergic effects

Content

  • All FDA labels and EMA EPARs for US and EU approved drugs
  • Available literature (articles from peer review journals, conferences and meeting abstracts) since 2013. This concerns launched drugs and also drugs in development
