The peptide drugs in a spray form cause a rapid therapeutic effect. Sometimes the action comes just as quickly as in injectable form. The effectiveness and bioavailability of the drug after intranasal administration is largely determined by the patient’s nasal mucosa state; you shouldn’t use intranasal administration in cases of cold, injuries or other pathology of the nasal mucosa.

Storage of the peptide drug in solution formulation for intranasal administration results in reduced stability of the active ingredient that provides a lower period of use of two years and requires a special temperature regimen of +8-10 °C.

This method of administration of the peptides is fast and convenient.
