Using different drugs simultaneously may trigger unexpected pharmacological effects. Therefore, efficient identification of drug interactions is essential for the treatment of complex diseases. Currently proposed calculation methods are often limited by the collection of redundant drug features, a small amount of labeled data and low model generalization capabilities. Meanwhile, there is also a lack of unique methods for multidrug representation learning, which makes it more difficult to take full advantage of the originally scarce data.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Inspired by graph models and pretraining models, we integrated a large amount of unlabeled drug molecular graph information and target information, then designed a pretraining framework, MGP-DR (Molecular Graph Pretraining for Drug Representation), specifically for drug pair representation learning. The model uses self-supervised learning strategies to mine the contextual information within and between drug molecules to predict drug\u2013drug interactions and drug combinations. The results achieved promising performance across multiple metrics compared with other state-of-the-art methods. Our MGP-DR model can be used to provide a reliable candidate set for the combined use of multiple drugs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Availability and implementation<\/jats:title><jats:p>Code of the model, datasets and results can be downloaded from GitHub (https:\/\/github.com\/LiangYu-Xidian\/MGP-DR).<\/jats:p><\/jats:sec><jats:sec><jats:title>Supplementary information<\/jats:title><jats:p>Supplementary data are available at Bioinformatics online.<\/jats:p><\/jats:sec>","DOI":"10.1093\/bioinformatics\/btac538","type":"journal-article","created":{"date-parts":[[2022,7,29]],"date-time":"2022-07-29T15:09:41Z","timestamp":1659107381000},"page":"4387-4394","source":"Crossref","is-referenced-by-count":22,"title":["Multidrug representation learning based on pretraining model and molecular graph for drug interaction and combination prediction"],"prefix":"10.1093","volume":"38","author":[{"given":"Shujie","family":"Ren","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Xidian University , Xi\u2019an, Shaanxi 710071, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8351-3332","authenticated-orcid":false,"given":"Liang","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Xidian University , Xi\u2019an, Shaanxi 710071, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6396-0787","authenticated-orcid":false,"given":"Lin","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Xidian University , Xi\u2019an, Shaanxi 710071, China"}]}],"member":"286","published-online":{"date-parts":[[2022,7,29]]},"reference":[{"key":"2023041408370729800_","doi-asserted-by":"crossref","first-page":"309","DOI":"10.1038\/nrd.2016.262","article-title":"Trends in the market for antihypertensive drugs","volume":"16","author":"Ali","year":"2017","journal-title":"Nat.
