With generators of tin dioxide and titanium dioxide-based adsorbents, there remains more than an hour of pharmaceutical preparation to attach the gallium-68 ( III ) as a tracer to the pharmaceutical molecules DOTATOC or DOTA-TATE, so that the total preparation time for the resulting radiopharmaceutical is typically longer than the Ga-68 isotope half-life.

Gallium-68, a positron emitter with a half-life of 68 min, is now used as a diagnostic radionuclide in PET-CT when linked to pharmaceutical preparations such as DOTATOC, a somatostatin analogue used for neuroendocrine tumors investigation, and DOTA-TATE, a newer one, used for neuroendocrine metastasis and lung neuroendocrine cancer, such as certain types of " microcytoma ".

There are pharmaceutical preparations of sodium phosphate as a phosphate source for intravenous or oral replacement of phosphate depletion ( e . g ., for treating people with diabetic ketoacidosis or X-linked hypophosphatemic rickets ), or as a buffer for those with certain types of impaired renal acidification . alteripse 11 : 24, 12 September 2005 ( UTC)
