What does ppa mean?

PPA usually refers to pipemidic acid or phenylpropanolamine hydrochloride in medicine, and the common PPA in gastrointestinal diseases refers to pipemidic acid.

Phenylpropanolamine hydrochloride can relieve cold symptoms, such as cough and nasal congestion, with serious side effects, such as headache, dizziness and blurred vision. In severe cases, blood pressure may rise, and palpitation may even induce cardiovascular diseases, such as arrhythmia and cerebral hemorrhage.

Therefore, after seeing a doctor in a regular hospital, doctors should prescribe drugs according to the doctor's advice to avoid self-harm or aggravation due to drug abuse.
