Summary
This study evaluated drug-drug interaction (DDI) screening programs, finding none ideal. Pharmavista demonstrated the highest sensitivity for detecting DDIs, making it a strong option for clinical use.
Area of Science:
- Pharmacology
- Clinical Pharmacy
- Health Informatics
Background:
- Drug-drug interactions (DDIs) pose significant risks in polypharmacy.
- Effective screening programs are crucial for patient safety and optimizing prescription management.
Purpose of the Study:
- To critically appraise the performance and suitability of available drug-drug interaction (DDI) screening programs.
- To identify strengths and weaknesses of leading DDI screening tools.
Main Methods:
- Nine DDI screening programs were evaluated against predefined minimal requirements.
- A comprehensive assessment included qualitative analysis of monographs and quantitative precision analysis using drug lists and patient profiles.
- Stockley's Drug Interactions served as the gold standard for comparison.
Main Results:
- Four programs met inclusion criteria: Drug Interaction Facts, Drug-Reax, Lexi-Interact, and Pharmavista.
- Pharmavista and Drug-Reax provided excellent DDI monographs, while Lexi-Interact offered less specific information.
- Pharmavista showed the highest sensitivity (0.86) and acceptable positive predictive value (0.67) against the gold standard, outperforming other evaluated programs.
Conclusions:
- No single DDI screening program is perfect; each has unique advantages and limitations.
- Pharmavista emerges as a leading option due to its superior sensitivity in identifying DDIs, with acceptable specificity and positive predictive value.
- Awareness of program-specific performance metrics is essential for informed selection and use in clinical practice.

01:30Drug toxicity: Drug–Drug Interaction
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...
01:25Pharmacokinetics: Drug–Drug Interactions
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...
01:26Therapeutic Drug Monitoring: Drug Analysis Methods
Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...
01:19Pharmacovigilance
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...

01:26Pharmacokinetics: Drug–Food and Drug–Viral Interactions
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 many...
01:01Dosage Regimens: Partial Pharmacokinetic Parameters
It is not uncommon for complete drug pharmacokinetic profiles to remain elusive in pharmacokinetics. This necessitates certain educated assumptions by pharmacokineticists to determine appropriate dosage regimens without comprehensive pharmacokinetic data from animal or human studies. One prevalent assumption is setting the bioavailability factor, denoted as F, to 1 or 100%. This assumption caters to the scenario where a drug doesn't achieve full systemic absorption, resulting in the patient...
