1.1.4 Code of Pharmaceutical Ethics
As adopted by Phannacy Council of India under chapter-I: General Introduction. The profession of pharmacy is noble in its ideals and pious in its character. Apart from being a career for earning livelihood it has inherent in it the attitude of service and sacrifice in the interests of the suffering humanity.

should be fondly cherished by all Pharmacist.
