Phenylpropanolamine (PPA)

Phenylpropanolamine (PPA) is another one of the Ephedra alkaloids similar to ephedrine, epinephrine, methamphetamine, and amphetamines. At one time it was found in a number of over-the-counter medications such as Contac®, Dexatrim™, Robitussin CF®, Dimatapp®, among others. PPA has been shown to produce peaks in blood pressure resulting in an increased incidence of hemorrhagic stroke. Signs and symptoms can include psychoses, seizures, acute hypertension, and severe headaches, among others. The report provided below contains more information about this harmful drug and how it is related to various health effects. Selected references are provided below.
