Hyperphenylalaninemia is a medical condition characterized by mildly or strongly elevated concentrations of the amino acid phenylalanine in the blood. Phenylketonuria (PKU) can result in severe hyperphenylalaninemia. [2] Phenylalanine concentrations are routinely screened in newborns by the neonatal heel prick (Guthrie test), which takes a few ...
Phenylephrine, sold under the brand names Neosynephrine and Sudafed PE among others, is a medication used as a decongestant for uncomplicated nasal congestion in the form of a nasal spray or oral tablet, [5] to dilate the pupil, to increase blood pressure given intravenously in cases of low blood pressure, and to relieve hemorrhoids as a suppository.
Individuals with this disorder are known as "phenylketonurics" and must regulate their intake of phenylalanine. Phenylketonurics often use blood tests to monitor the amount of phenylalanine in their blood. Lab results may report phenylalanine levels using either mg/dL and μmol/L. One mg/dL of phenylalanine is approximately equivalent to 60 ...
Processed Foods Raise Blood Pressure. Yes, many ultra-processed foods (think doughnuts, candies and hot dogs) are not the best choices for our health. However, there are a surprising number of ...
Life-threatening problems can result when drug interactions between your daily medications cause side effects, and nowhere might that be more clear than with Viagra and high blood pressure.
Midodrine is a prodrug which forms the active metabolite, desglymidodrine, which is an α 1-adrenergic receptor agonist and exerts its actions via activation of α 1-adrenergic receptors of the arteriolar and venous vasculature, producing an increase in vascular tone and elevation of blood pressure.
“Heavy drinking raises blood pressure, increases triglycerides, promotes inflammation and can cause arrhythmias, all of which elevate the risk of heart disease and stroke,” says Routhenstein.
The amino acids phenylalanine and tyrosine are precursors for catecholamines. Both amino acids are found in high concentrations in blood plasma and the brain. In mammals, tyrosine can be formed from dietary phenylalanine by the enzyme phenylalanine hydroxylase, found in large amounts in the liver.
