The present invention relates to oral therapy of a subject suffering from disease e.g. polycystic disease e.g. polycystic kidney disease or polycystic liver disease or PCOS or hypotension especially neurogenic orthostatic hypotension and postprandial hypotension, or intractable diarrhea or neuroendocrine tumors or carcinoid syndrome. The method of treatment comprises oral administration to the subject of a therapeutically effective amount of an oral somatostatin receptor ligand (SRL) e.g. oral octreotide. Combination therapy of oral SRLs with other drugs is also envisaged, e.g. octreotide in combination with a therapeutically effective amount of a second therapeutic agent and optionally in combination with a therapeutically effective amount of a third therapeutic agent.
