Interaction Details
Ribociclib Succinate is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, Polypodium leucotomos might increase levels of drugs metabolized by CYP3A4.
In vitro and animal research suggests that Polypodium leucotomos can decrease the metabolism of midazolam by a mechanism possibly related to the inhibition of CYP3A4. However, a small study in humans suggests that taking Polypodium leucotomos with midazolam does not affect the metabolism of midazolam.

Ribociclib Succinate Overview
-
Ribociclib is used in combination with another medication to treat a certain type of hormone receptor–positive (depends on hormones such as estrogen to grow) advanced breast cancer or that has spread to other parts of the body in women who have not experienced menopause (change of life; end of monthly menstrual periods) and in those who are close to or who have already experienced menopause. Ribociclib is also used in combination with fulvestrant (Faslodex) to treat a certain type of hormone receptor–positive advanced breast cancer or that has spread to other parts of the body as an initial treatment or in people who have not been treated successfully with other treatments in women who have already experienced menopause. Ribociclib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.
