Α-Methyl-p-tyrosine
(Redirected from Metirosine)
Α-Methyl-p-tyrosine (also known as AMPT) is a tyrosine hydroxylase inhibitor and an important pharmaceutical drug used in the treatment of various medical conditions. It is a derivative of the amino acid tyrosine and acts by inhibiting the action of the enzyme tyrosine hydroxylase, which is crucial in the synthesis of catecholamines like dopamine, norepinephrine, and epinephrine.
Pharmacology[edit | edit source]
Α-Methyl-p-tyrosine works by inhibiting the enzyme tyrosine hydroxylase, which is the rate-limiting enzyme in the synthesis of catecholamines. By inhibiting this enzyme, AMPT effectively reduces the production of dopamine, norepinephrine, and epinephrine, thereby affecting various physiological processes that are regulated by these neurotransmitters.
Medical Uses[edit | edit source]
Α-Methyl-p-tyrosine is primarily used in the treatment of pheochromocytoma, a rare tumor of the adrenal glands that results in overproduction of catecholamines. By inhibiting the synthesis of these neurotransmitters, AMPT can help control the symptoms of this condition.
In addition, AMPT has been used in research settings to study the role of catecholamines in various physiological and psychological processes, including mood regulation, stress response, and cognitive function.
Side Effects[edit | edit source]
Like all drugs, Α-Methyl-p-tyrosine can cause side effects. These may include nausea, headache, fatigue, and dizziness. In rare cases, it can cause more serious side effects like hypotension (low blood pressure) and psychiatric symptoms such as depression or anxiety.
