Clinical pharmacists are health care practitioners who have advanced education and training in comprehensive medication management. Clinical pharmacists participate in the management of specific medications or individual disease states and collaborate with other health care team. Despite the clinical pharmacist participate in healthcare team, there are several cases of challenge in the interprofessional relationship with other healthcare team especially related drug management. The role of clinical pharmacists could be improved by increasing interprofessional communication between doctors and clinical pharmacist in the healthcare system. Previous studies reported that physicians were comfortable with pharmacists detecting and preventing prescription errors, but were uncomfortable with them recommending drug therapy to patients. Acceptance of pharmacists' suggestions by prescribers is a necessary component of the evaluation of clinical pharmacy services.
