  • Oral solid dosage forms containing a low dose of estradiol
    Patent number: 8022053
    Abstract: The present invention relates to oral solid dosage forms containing a very low dose of estradiol. The dosage forms are formulated in a manner so as to avoid degradation of the estradiol and to minimise the content of polyvinylpyrrolidone, while still achieving similar fast dissolution of the estradiol. The dosage forms are useful in preventing or treating a physical condition in a woman caused by insufficient endogenous levels of estradiol.

  • ESTRADIOL-CONTAINING DRUG DELIVERY SYSTEM
    Publication number: 20110097405
    Abstract: The present invention relates to drug delivery systems in the form of thin water-soluble films (wafers), which contain estradiol, or derivatives thereof, in low amounts. The wafers of the present invention are suitable for treating, alleviating or preventing a physical condition in a female mammal caused by insufficient endogenous levels of estrogen.
