Summary
Lexi-Interact and Epocrates were the most accurate drug-drug interaction (DDI) screening software. Combining multiple programs with pharmacist expertise can improve DDI detection sensitivity.
Area of Science:
- Pharmacology
- Clinical Pharmacy
- Health Informatics
Background:
- Drug-drug interactions (DDIs) pose significant risks, leading to treatment failure and adverse events.
- DDIs screening software is crucial for clinicians but has limitations.
- Evaluating the performance of common DDI software is essential for safe medication management.
Purpose of the Study:
- To compare the accuracy and comprehensiveness of five common drug-drug interaction (DDI) screening programs.
- To assess the sensitivity, specificity, and predictive values of these DDI software tools.
- To identify the most effective DDI screening software for clinical use.
Main Methods:
- Five DDI programs (Lexi-Interact, Micromedex, iFacts, Medscape, Epocrates) were evaluated.
- Accuracy was assessed using 360 unknown and 40 known clinically important interaction pairs.
- Comprehensiveness was determined by monograph content; expert clinical pharmacist and literature review served as the reference standard.
Main Results:
- Lexi-Interact and Epocrates achieved the highest accuracy scores (250/400).
- iFacts led in comprehensiveness (134/134), with Lexi-Interact second (120/134).
- Lexi-Interact (370/534) and Micromedex (330/534) demonstrated superior overall competence, completeness, and user-friendliness.
Conclusions:
- Lexi-Interact and Micromedex exhibited the best overall performance in DDI screening.
- Combining multiple DDI software programs with clinical pharmacist expertise can enhance detection sensitivity.
- Informed selection and use of DDI software are vital for mitigating risks associated with drug interactions.

01:30Drug toxicity: Drug–Drug Interaction
208
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...

01:14Agonism and Antagonism: Quantification
1.3K
When drugs are administered, they can elicit either an agonist or antagonist effect on the body. Agonism occurs when a drug activates a specific receptor, triggering a biological response. On the other hand, antagonism happens when a drug binds to the same receptors but blocks their activation, thereby preventing a biological response.
To quantify these effects, researchers use a dose-response curve, which provides valuable information about the potency and efficacy of a drug. Potency refers to...

01:25Pharmacokinetics: Drug–Drug Interactions
586
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...

01:29Drug-Receptor Interactions
8.0K
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....

01:30Quantitative Aspects of Drug-Receptor Interaction
2.0K
The receptor occupancy theory connects a drug's response to the number of occupied receptors. With higher drug concentrations, more receptors are occupied, leading to increased responses. The formation of drug-receptor complexes involves association and dissociation rates, which reach equilibrium when the forward and backward reactions are equal. The equilibrium association constant (Ka) and its inverse, the equilibrium dissociation constant (Kd), indicate drug affinity. Higher Ka and lower...

01:20Drug Product Performance: In Vitro–In Vivo Correlation
340
In pharmaceutical development, it's crucial to establish a predictive in vitro–in vivo correlation (IVIVC) for two or more formulations to gain a comprehensive understanding of release properties. IVIVC reduces the need for costly in vivo studies and facilitates the establishment of meaningful dissolution specifications with significant cost savings and decreased regulatory burden. Furthermore, a meaningful IVIVC should predict Cmax and AUC within 20%, aligning with FDA guidance while...
