Bioavailability

ExcerptReferenceRelevance
" 163, administered as their DL-racemic mixtures, produced increases in the t1/2 and bioavailability of co-administered L-DOPA comparable to that produced by a 10-fold larger dose of carbidopa administered as the active L-enantiomer; increasing the dose of MDL 72."( A comparison of the effects of reversible and irreversible inhibitors of aromatic L-amino acid decarboxylase on the half-life and other pharmacokinetic parameters of oral L-3,4-dihydroxyphenylalanine.

5-hydroxytryptophan
5-Hydroxytryptophan: The immediate precursor in the biosynthesis of SEROTONIN from tryptophan. It is used as an antiepileptic and antidepressant.. 5-hydroxytryptophan : A tryptophan derivative that is tryptophan substituted by a hydroxy group at position 5.		6.9510hydroxytryptophanhuman metabolite;

3,4-dihydroxyphenylacetic acid
3,4-Dihydroxyphenylacetic Acid: A deaminated metabolite of LEVODOPA.. (3,4-dihydroxyphenyl)acetic acid : A dihydroxyphenylacetic acid having the two hydroxy substituents located at the 3- and 4-positions. It is a metabolite of dopamine.. dihydroxyphenylacetic acid : A dihydroxy monocarboxylic acid consisting of phenylacetic acid having two phenolic hydroxy substituents.		1.9810catechols;
dihydroxyphenylacetic acid		human metabolite
dihydroxyphenylalanine
Dihydroxyphenylalanine: A beta-hydroxylated derivative of phenylalanine. The D-form of dihydroxyphenylalanine has less physiologic activity than the L-form and is commonly used experimentally to determine whether the pharmacological effects of LEVODOPA are stereospecific.. dopa : A hydroxyphenylalanine carrying hydroxy substituents at positions 3 and 4 of the benzene ring.		2.8840hydroxyphenylalanine;
non-proteinogenic alpha-amino acid;
tyrosine derivative		human metabolite
pyridoxal phosphate
Pyridoxal Phosphate: This is the active form of VITAMIN B 6 serving as a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into pyridoxamine phosphate (PYRIDOXAMINE).. pyridoxal 5'-phosphate : The monophosphate ester obtained by condensation of phosphoric acid with the primary hydroxy group of pyridoxal.		1.9510methylpyridines;

benserazide
Benserazide: An inhibitor of DOPA DECARBOXYLASE that does not enter the central nervous system. It is often given with LEVODOPA in the treatment of parkinsonism to prevent the conversion of levodopa to dopamine in the periphery, thereby increasing the amount that reaches the central nervous system and reducing the required dose. It has no antiparkinson actions when given alone.. benserazide : A carbohydrazide that results from the formal condensation of the carboxy group of DL-serine with the primary amino group of 4-(hydrazinylmethyl)benzene-1,2,3-triol. An aromatic-L-amino-acid decarboxylase inhibitor (DOPA decarboxylase inhibitor) that does not enter the central nervous system, it is used as its hydrochloride salt as an adjunct to levodopa in the treatment of parkinsonism. By preventing the conversion of levodopa to dopamine in the periphery, it causes an increase in the amount of levodopa reaching the central nervous system and so reduces the required dose. Benserazide has no antiparkinson actions when given alone.		1.9810carbohydrazide;

levodopa
Levodopa: The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system..
