Summary for Patent: 5,855,906
| Title: | Intravaginal drug delivery devices for the administration of 17β-oestradiol precursors |
| Abstract: | The invention relates to an intravaginal drug delivery device for administration to a female mammal of certain 17β-oestradiol precursors at a substantially constant rate for a period of at least three weeks. The 17β-oestradiol precursor is a 17β-oestradiol moiety in which the, or each, hydroxyl group of the 17β-oestradiol moiety is blocked by a blocking group, which blocking group is readily removed from the 17β-oestradiol in vivo. The 17β-oestradiol precursor must have either a solubility in liquid silicone of not less than 0.1 mg/100 ml or a standard k value of not less than 0.1 μg/day/mm. The 17β-oestradiol precursor must also have a solubility in distilled water of not less than 1 μg/100 ml. |
