QuestionMy doctor has suggested that I change from daily Actonel to once a week Foxamax. ( I was diagnosed with mild osteoporosis a year ago and I have lost 1/4 inch in height in the year I have been taking Actonel.)
I don't understand how once a week can be as good for my bones as daily. He says the once a week pill releases slowly into my system, but I don't understand how a pill can time release for a week. Can you help me understand?
AnswerThe weekly effect on the bone is the same as daily dosing, so there is really no advantage to dosing once a day. It is not necessarily how long the drug lasts is in the blood, but how long the drug effects the bone.
There is also a newer agent that must be given IV that can be dosed YEARLY!
