The pharmaceutical analysis may be defined as a procedure or the sequences of progressions to identify or quantify a constituent or drug, the mechanisms of a pharmaceutical solution or fusion or the determination of the structures of chemical combinations used in the formulation of pharmaceutical product. Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
