Today the latest concept in medicine is towards individualization of drug therapy. Where judicious patient care is needed individualization of drug therapy becomes a need, and a pharmacist can play a vital role in this. A physician who is preoccupied with patient diagnosis and treatment may not spare time for patient counseling regarding pharmaco-economics, drug information, alternative therapy, moral supporting etc. A pharmacist can set up a separate consultation room and provide counseling to the patient. He can store the details of patient history, allergies and other details necessary for therapy so that the concept of individualization of drug therapy could be implemented.
The World Health Organisation (WHO) introduced the concept of the "seven-star" pharmacist" to cover the roles of a pharmacist, i.e.: caregiver, decision-maker, communicator, manager, life-long learner, teacher and leader. Later “Research” was added as an eighth category, which formed the Eight Star pharmacist categorie.
