Objectives:
Patients with cancer who use complementary and alternative medicines (CAMs) in conjunction with chemotherapy treatment are at risk of manifesting anticancer drug-CAM interactions (DCIs), which may lead to negative therapeutic outcomes. This article describes a novel iPhone application developed for the Mobile Internet, called OncoRx-MI, which identifies DCIs of single-agent and multiple-agent chemotherapy regimen (CReg) prescriptions.
Methods:
Drug-, CAM-, and DCI-related information was compiled from various hardcopy and softcopy sources, and published literature from PubMed. Overall management plans for the CRegs were then developed. The iPhone Web documents were constructed using Adobe software and programming scripts, and mounted onto a third-party server. DCI searches are based on CReg acronyms, and OncoRx-MI is designed to fit the iPhone screen configuration for improved usability. A small usability study was also carried out and the user feedback presented.
Results:
OncoRx-MI is able to detect over 2700 interactions between 256 CRegs and 166 CAMs, making up a total of over 4400 DCI pairs. The CAMs are classified into seven categories based on their uses in supportive care, and non-cancer-related CAMs are also included. The majority of the DCIs are pharmacokinetic in nature (79%), involving the induction and inhibition of the cytochrome P450 isozymes and p-glycoprotein. Pharmacodynamic DCIs include hepatotoxicity (39%), altered corticosteroid efficacies (30%), and increased risks of hypoglycemia (4%), hypertensive crisis (2%), bleeding, and serotonin syndrome (1% each).
Conclusions:
OncoRx-MI is the first mobile application of its kind that allows searching of DCIs for CRegs through 3G networks, and is intended to improve pharmaceutical care of patients with cancer by assisting health care practitioners in managing CReg interactions in their clinical practices.
Insights
A new iPhone app, OncoRx-MI, identifies drug-CAM interactions for chemotherapy regimens, helping oncologists manage potential adverse events. This tool aids in improving pharmaceutical care for cancer patients by flagging over 4400 potential interactions.
Area of Science:
- Oncology
- Pharmacology
- Mobile Health
Background:
- Complementary and alternative medicines (CAMs) use in cancer patients can lead to dangerous drug-CAM interactions (DCIs) with chemotherapy.
- These interactions may negatively impact therapeutic outcomes for cancer patients.
Purpose of the Study:
- To describe OncoRx-MI, a novel iPhone application designed to identify DCIs.
- To aid healthcare practitioners in managing chemotherapy regimen (CReg) interactions.
Main Methods:
- Compiled drug, CAM, and DCI data from literature and databases.
- Developed CReg management plans and iPhone Web documents.
- Implemented DCI searches based on CReg acronyms for mobile usability.
Main Results:
- OncoRx-MI detects over 4400 DCI pairs between 256 CRegs and 166 CAMs.
- 79% of DCIs are pharmacokinetic, affecting drug metabolism (e.g., cytochrome P450).
- Pharmacodynamic DCIs include hepatotoxicity (39%) and altered drug efficacies.
Conclusions:
- OncoRx-MI is the first mobile app to search CReg-CAM interactions via 3G.
- The application aims to enhance pharmaceutical care for cancer patients.
- It assists clinicians in managing complex CReg interactions.
