The Institute of Pharmacy has been established with a view to promote excellence in pharmaceutical education and to prepare young men and women to meet the challenges in the area of pharmaceutical industries, education, research and development and marketing. We aim to provide degree, postgraduate, doctoral and postdoctoral level education at this centre of excellence. The pharmacy profession in Gujarat and western part of India has been striving for such a centre and establishment of IP.

The history of Jamia Hamdard begins with the establishment of a small Unani clinic in the year 1906 by Hakeem Hafiz Abdul Majeed, one of the well-known practitioners of Unani System of Medicine of his time. Hakeem Hafiz Abdul Majeed had a vision of making the practice of Unani Medicine into a scientific discipline so that Unani medicines could be dispensed in a more efficacious manner to patients. He gave the name "Hamdard" to his venture which means "sympathy for all and sharing of pain".

SUSPENSION
Pharmaceutical suspension may be defined as coarse dispersions in which insoluble solids are suspended in a liquid medium. Insoluble solids may have a size range from 10 to 1000 µm.

STABILITY OF SUSPENSION
It is important to understand that suspensions are kinetically stable, but thermodynamically unstable, system.
Physical stability is defined as the condition in which the particles remain uniformly distributed throughout the dispersion without any signs of sedimentation. It is difficult to achieve this condition. Hence the definition can be restated as –if the particles settle they should be easily resuspendable by moderate amount of shaking.
