Glass vials (Type I Ph. Eur.) of 10 mL nominal capacity, sealed with a bromobutyl stopper and an aluminium cap.


The aluminium cap for vial I is blue and the aluminium cap for vial II is white in order to distinguish vial I from vial II during the reconstitution/radiolabelling procedure.


Vials I and II contain components for the radiopharmaceutical preparation of 99mTc-Tektrotyd.


Each vial contains a white or nearly white lyophilisate for preparation of a solution for injection.


Vial I: Active substance: HYNIC-[D-Phe1, Tyr3-Octreotide]  trifluoroacetate,
excipients: stannous chloride dihydrate, N‑[Tris(hydroxymethyl)methyl]glycine (tricine), mannitol, sodium hydroxide or hydrochloric acid for pH adjustment, nitrogen


Vial II: Excipients: ethylenediamine-N,N’-diacetic acid (EDDA),


disodium phosphate dodecahydrate, sodium hydroxide, sodium hydroxide or hydrochloric acid for pH adjustment, nitrogen


Pack size: 2 vials


Range of activity: 


This medicinal product is for diagnostic use only.


After radiolabelling with sodium pertechnetate (99mTc) solution, the solution of 99mTc-Tektrotyd obtained is indicated for use in adults as adjunct in the diagnosis and management of somatostatin receptor bearing neuroendocrine tumours (NET), by aiding their localization.


Tumours which do not bear somatostatin receptors will not be visualised.
