4/25/2010I am not sure I completely understand your question. Tykerb is generally dosed as a once a day drug. Dividing doses can affect and alter the metabolism of the drug, but that should never be done without first consulting with your oncologist. So taking the same number of tablets but dividing the dose can alter the blood levels for any medication, but for now, one should always take the drug as prescribed. Further dosing modifications based upon clinical trials may change that in the future, but again, only take medications as prescribed by your doctor. Best wishes!
