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...

Demand for measuring estradiol at low concentrations is increasing, and the widely used \'direct\' radioimmunoassays that do not require a preliminary organic purification step may be inadequate in patient care because of their limited accuracy. In observational epidemiology, however, the main concern is to obtain a correct ranking of individuals\' hormone concentration relat...
