What is phenylpropanolamine?

phenylpropanolamin, also known as PPA, is a psychoactive drug that has a stimulant, decongestant and anorexic effects. It works by causing the body to release its own natural stimulation chemicals - norepinephrine, epinephrine and dopamine. It is used to treat symptoms of colds and allergies and was previously a common component in over -the -counter cold drugs and weight loss preparations. In the US, it is no longer available without a prescription due to security concerns after the studies have revealed the link between phenylpropanolamine and hemorrhagic stroke. It was also removed from the market in some other countries. It causes a stimulant, a decongestant and a reduction in appetite or an anorectic action. Its method of action is to cause the body to release norepinephrine, epinephrine and dopamine. These substances are neurotransmitters that also act as hormones in the body and are associated with the reaction of "fighting or flight" to stress. They have a stimulating effect that involves increasing blood pressure, heart rate and alertness.

credited with prescription, phenylpropanolamine is often used as a decongestant for the treatment of colds and allergies in the upper respiratory. It works by reducing or limiting the blood vessels in the nose, cavity and chest. This reduces the swelling in these areas and allows drainage of caught mucus. Common side effects include dizziness, drowsiness, lightness, nervousness, nausea, headache and insomnia. Phenylpropanolamine was also a common ingredient in many over -the -counter remedial remedials for cold and allergies.

In addition to its stimulating action, phenylpropanolamine has the ability to act as a suppressing appetite. This combination of effects is typical of many types of drugs. For this reason, it was included as a component in several weight loss preparations. However, these weight loss supplements were reformulated by other ingredients.

Studies have shown that there is a link between phenylpropanolamine and hemorrhagic stroke, especially in young women. Since then, US food and drug administration (FDA) has removed it from an over -the -counter market and is only available as prescription. It was also removed from the market in several countries, including Canada and Australia, but the drug is still available for sale in many countries in Europe, such as the United Kingdom. If it is prescribed by a doctor, it should only be used for a short time. It is also important that the patient assures that the doctor is aware of his complete medical history.
