Pharmaceutical care requires substantial contributions from patients, informal caregivers, the interprofessional team of healthcare professionals, and health care system managers. Before patients to fully benefit from contemporary medicine, parties must collaborate, show mutual respect, and agree on duties throughout the complicated process of pharmaceutical treatment. In this position paper, we analyze the potential for integrated evidence-based pharmaceutical care to enhance care quality and patient outcomes from a nursing standpoint, drawing on literature and policy documents. Although there is agreement on the need of interprofessional cooperation, difficulties in clinical practice, research, education, and policy-making are frequently not dealt with collaboratively. Nurses are expected by healthcare professionals to communicate their observations and assessments. The essential patient information should be shared and discussed by the interprofessional team.
