In recent times, biopharmaceuticals have gained attention because of their tremendous potential to benefit millions of patients globally by treating widespread diseases such as cancer, diabetes and many rare diseases. Short peptides (SP), also termed as oligopeptides, are one such class of biopharmaceuticals, that are majorly involved in efficient functioning of biological systems. Peptide chains that are 2-20 amino acids long are considered as oligopeptides by researchers and are some of the functionally vital compounds with widespread applications including self-assembly material for drug delivery, targeting ligands for precise/specific targeting and other biological uses. Using functionalised biomacromolecules such as short chained peptides, helps in improving pharmacokinetic properties and biodistribution profile of the drug. Apart from this, functionalised SP are being employed as cell penetrating peptides and prodrug to specifically and selectively target tumor sites. In order to minimize any unwanted interaction and adverse effects, the stability and safety of SP should be ensured throughout its development from manufacturing to market. Formulation development and characterization strategies of these potential molecules are described in the following review along with various applications and details of marketed formulations.
