Tackling the Task of Curing the Cough

 Americans end up spending $4 billion a year on over-the-counter remedies that the American College of Chest Physicians says show little evidence of effectiveness. The grugs available today only effect the brain and not the actual airwaves, but a new drug TRPV1 generated attention for its potential to be the target of new drugs, especially for pain. It also kicked off new interest in cough, pulling researchers into the field. Blocking the receptor, it was thought, could stop a cough at its source.The success of using TRPV1 inhibitors depends on the ability to overcome the side effects of impaired thermoregulation while still blocking cough or pain
