Are the any creams that have triamcinolone acetonide bp 1 mg econazole nitrate bp 10 mg gentamicin sulphate bp 1 mg sold in america?

Don't think so: Haven't heard of that combination cream. However, individual creams can be prescribed if needed, and a patient can use a little bit from each tube of cream, to treat a particular rash if her doctor feels that such medications are the proper treatment of that rash. Usually, there is more than one type of cream able to treat a rash, which means that alternatives should also be available in the US.
