ABSTRACT
Stability studies of drugs are necessary for betterment of patients for
clinical efficacy of formulations and for drug regulatory requirements.
In Unani classical literatures Unani scholars mentioned the different
expirations dates of various Unani single and compound formulations.
A validation of these claims is the challenge for all Unani
pharmaceutics. It is also a challenge for its global marketing. Unani
system of medicine (USM) employs single drugs, simple preparations
and compound preparations (using herbs, minerals and animal products
in one and the same medicine) so the task of evolving standards and
shelf life is enormous. There is no scientific ground, whatsoever; to fall
back and as a composite strategy had to be evolved. Unani
pharmacopoeias have mentioned the shelf life of various drugs, which
is empirical. Keen observation and use of drugs from centuries has made it possible to
evaluate the life of drugs for its use. On the basis of authority, the expiry dates of various
drugs have been mentioned in classical literatures of USM. This paper gives an overview of
shelf life of Unani single drugs.
Keywords: Shelf life, Unani drugs, Stability Studies, Expiry dates.
