Mixtard 30 is one of the commonly used biphasic insulins.
Some newer devices deliver lower energy shocks using biphasic waveforms.
Biphasic oral contraceptives use a constant amount of estrogen during the full cycle, but the amount of progestin is lower during the first half of the cycle and increases in the second half.
The goal of the biphasic and triphasic formulations is to achieve adequate control of the menstrual cycle while using lower doses of both estrogens and progestins, thereby reducing the risk of adverse effects.
There are three main types of pill packs and hormone combinations – monophasic, biphasic, and triphasic.
