Cap Prices on Children's Medications

I have been a nurse in pediatrics for 13 years. Drug companies charge as much money as they can get away with. I have had to do hundreds of prior authorizations on medications such as antibiotics,asthma maintaince and insulin maintaince medicines. They can deny these medications and leave the parents paying outrageous prices out of pocket and not have to give an explanation. Something needs to be done. No parent should have to deal with this.
