New chemo drug Camptosan

If Camptosan is Irinotican, my husband had this as part of his FOLFIRI cocktail for colon cancer.  This is how FOLFIRI is broken down by drug: 

FOLFIRI is a chemotherapy regimen for treatment of colorectal cancer. It is made up of the following drugs:

• FOL – folinic acid (leucovorin), a vitamin B derivative used as a "rescue" drug for high doses of the drug methotrexate, but increases the cytotoxicity of 5-fluorouracil;
• F – fluorouracil (5-FU), a pyrimidine analog and antimetabolite which incorporates into the DNA molecule and stops synthesis; and
• IRI – irinotecan (Camptosar), a topoisomerase inhibitor, which prevents DNA from uncoiling and duplicating.

My husband tolerated this much better than FOLFOX.  He was also told it would likely cause diarrhea but because he was usually constipated it kind of balanced him out.  His hair did thin quite a bit and our daughter buzzed his hair really short.  He did get the acne on his face and chest that kind of bothered him.  He got a lotion prescription which worked well.

I don't think this is a new drug for treatment, it might just be a new drug for you. 

I misread, and thought you   were asking about Camptosar, which is different from Camptosan, but haven't figured out how to delete a post.  I'm on Camptosar now, combined with Erbitux.   I understand some of the side effects include diarrhea, but I haven't had a problem with that yet, perhaps because the Erbitux causes constipation and they've cancelled each other out. Either way, the  onc gave me a prescription for Lomotil, just in case.   I've noticed   a lot more fatigue, and a kind of lighteaded, wonky feeling, but don't know yet whether that's caused by one or the other or the combination or something else entirely. I was also warned that  hair loss is likely, probably beginning after the second round.  Did your husband recieve an info sheet on the  Camptosar, which is also known as Irinotecan? The oncology nurses always give me info sheets and go over the info with me  when I sart on a new drug.  I've found the info sheets and explanations to be  very helpful in knowing what to expect.
