Levodopa, a dopamine precursor administered with a decarboxylase inhibitor, is the principal therapy for treating the symptoms of Parkinson's disease. Unfortunately, after approximately 2-5 years, it frequently loses its beneficial effects as evidenced by motor fluctuations. Entacapone (Comtan) is a
BACKGROUND
Recent genetic association studies have investigated the possible genetic role of the dopaminergic system in migraine. Catechol-O-methyltransferase (COMT) is an enzyme that plays a crucial role in the metabolism of dopamine and its genetic polymorphism is associated with three- to
BACKGROUND
Differences in the gastrointestinal manifestations have emerged between Swedish and Japanese familial amyloidotic polyneuropathy amyloidogenic transthyretin Valine30Methionine (FAP ATTR Val30Met) patients. To elucidate the cause of the differences, we investigated the associations between
BACKGROUND
When levodopa therapy is used in Parkinson's disease, degradation of the drug in the peripheral nervous system is associated with dyskinesias and motor fluctuations. Much of this degradation is produced by catechol-O-methyltransferase (COMT), an enzyme involved in the metabolism of
OBJECTIVE
To evaluate the influence of µl-opioid receptor (OPRM1) 118A>G and catechol-O-methyltransferase (COMT) 1947G>A gene single nucleotide polymorphisms (SNP) combinations on postoperative opioid analgesia (POA) efficacy.
METHODS
In 100 consecutive patients scheduled for major urologic
BACKGROUND
Genotype frequencies for chemotherapy-induced nausea and vomiting (CINV)-related polymorphisms have not yet been reported for Japanese subjects.
METHODS
We analyzed 10 genotype frequencies for following polymorphisms associated with the development of CINV: serotonin 5-HT3 receptors
There are individual differences in the frequency of chemotherapy-induced nausea and vomiting (CINV) in cancer patients. We investigated the individual variability in susceptibility to CINV with focus on both behavioral factors and genetic factors in Japanese cancer patients. We performed a
BACKGROUND
Previous studies have generated controversial results regarding the influence of the genetic variations of μ-opioid receptors on morphine analgesia and opioid-related side effects in the postoperative period. Few studies have been conducted attempting to assess the combined effects of
Postoperative nausea and vomiting (PONV) are two of the most frequent and distressing complications following surgical procedures, with as many as 80% of patients considered to be at risk. Despite recognition of well-established risk factors and the subsequent use of clinical guidelines, 20-30% of
BACKGROUND
As Parkinson's disease progresses the control of the symptoms often requires the addition of other drugs to levodopa. The principle aim of COMT inhibitor therapy is to increase the duration of effect of the levodopa dose and thus reduce the time patients spend in the relatively immobile
BACKGROUND
As Parkinson's disease progresses the control of motor symptoms often requires the addition of other drugs to levodopa. The principle aim of COMT inhibitor therapy is to increase the duration of effect of each levodopa dose and thus reduce the time patients spend in the relatively
Opicapone is a new catechol O-methyltransferase (COMT) inhibitor indicated for use as adjunct to levodopa therapy in patients with Parkinson's disease (PD) and motor fluctuations.To characterize the safety and tolerability of adjunct opicapone (25 and 50 OBJECTIVE
To assess the efficacy and tolerability of the catechol-O-methyltransferase inhibitor tolcapone in reducing "off/on" fluctuations in levodopa-treated parkinsonian patients.
METHODS
A randomized, double-blind, placebo-controlled, parallel-group study.
METHODS
Fifteen Parkinson disease
OBJECTIVE
To introduce entacapone, a new catechol-O-methyltransferase inhibitor, and discuss its pharmacology, pharmacodynamics, pharmacokinetics, clinical efficacy, drug interactions, adverse events, dosage guidelines, and therapeutic and formulary considerations.
METHODS
A MEDLINE database search
PF-06649751 is a novel, oral, non-catechol-based, D1/D5 dopamine receptor partial agonist under investigation for the treatment of motor symptoms associated with Parkinson's disease.A 15-week, phase II, double-blind, placebo-controlled clinical trial was
