  • Patent number: 4874793
    Abstract: This invention discloses the use of a dibenzo cycloheptene deriative, generally known as protriptyline for the treatment of mental health problems in children, specifically Attention Deficit Syndrome or Attention Deficit Disorder. By administering the correct dosage of this drug, children have shown improved concentration, improved sleep patterns, less behavioral problems both in school and at home and an overall improvement in the child behavior. This new use for protriptyline is unexpected and is contraindicated in the literature since protriptyline has commonly been used only as a antidepressant for adults and not as a mild stimulant in the treatment of childhood mental health problems, such as Attention Deficit Disorder or Syndrome.
