One of the recent tricks of the trade is the introduction of medications that are purified versions of older medications. Most medications contain a mix of molecules of the drug that are mirror images of eachother, like a right and a left hand. One of the "mirror images" is more active in the body than the other. The industry is able to take an old drug and purify it to only the active ingredient and create a new patent allowing them to continue to charge brand name prices for the medication. Common examples are Lexapro and Focalin which are no more effective than their older brothers: Celexa and Methylphenidate.
Another trick is the introduction of fancier coverings for meds. ADHD stimulant meds are essentially made from only two medications (methylphenidate and amphetamine). But there are over a dozen brand names. The main difference between the medications is their "delivery system" which basically means how the pill is coated.
My message to the average consumer is DON'T PAY ATTENTION TO ADS, COMMERCIALS, AND BILLBOARDS when it comes to medicating your kids. Find a good doctor and have a nice long talk about the options and choose the one that makes the most sense medically, financially, and ethically.
