CHildren's cough Study


Is your child coughing?


Clinical Research Associates is conducting a research study to learn more about an investigational drug that contains dextromethorphan hydrobromide (DXM HBr), a common ingredient found in cough medications. This ingredient is already approved in the United States. Even thought it is found in approved cough medications, DXM HBr is considered investigational for the purposes of this study. We will be comparing the effects of the study drurg with that of a placebo (no active ingredient) in children with a common cold or upper respiratory tract infection. The results of this study will provide information about the use of DXM HBr in children with a cough.

Who is eligible to participate?

To qualify for this study, your child must:

  • Be 6 to 11 years of age
  • Have a cough and other symptoms consistent with a common cough or upper respiratory tract infection
  • Have developed symptoms within 3 days of joining the study


What does the study entail?


There are 3 office visits, and the duration of the study is 4 to 6 days. The child will wear a cough recording device for 24 hours, take a total of 10 doses of his/her assigned medication, and keep a diary. The child will have a physical exam and complete some questionnaires. There are no blood draws and no insurance is necessary. The study staff will make a follow-up call to you in 14 days after the last dose of study drug to check on your child's well-being. The study is at no cost to you and you may receive reimbursement for reasonable expenses and travel.
