PharmaPendium - Foresee the Best Drug Development Strategy, model Drug Behavior In Vivo.

PharmaPendium offers dedicated data modules that provide insights and information on the critical focused areas of drug development, drug safety, ADME and drug-drug interactions. Challenges are inevitable on the path to regulatory approval of drug candidates. Successful drug development involves anticipating those challenges as early as possible. Comparative and up-to-date information is needed to verify pharmacokinetic and experimental data, anticipate species-specific issues in translating in vitro and in vivo studies, predict potential drug–drug interactions and design trials to best preclude regulatory issues.

To successfully perform critical functions such as pharmacovigilance, generating high-quality systematic reviews in support of evidence-based medicine and drug and medical device efficacy studies, pharmaceutical and life sciences organizations require a wide array of biomedical evidence. Embase increases the discovery of biomedical evidence to support critical life sciences functions, delivering relevant, up-to-date biomedical information to the global biomedical research community.
