Chronic tension-type headache may be caused by prolonged painful input from pericranial myofacial tissues, for example tender points, resulting in central sensitisation (increased excitability of neurons in the central nervous system). Animal studies have shown that sensitisation of pain pathways
It has been demonstrated recently that nitric oxide synthase (NOS) inhibition has an analgesic effect in patients with chronic tension-type headache. The aim of the present study was to investigate the influence of the NOS inhibitor, L-N(G) methyl arginine hydrochloride (L-NMMA), on two of the most
BACKGROUND
Studies in animals have shown that nitric oxide plays an important part in central sensitisation and that inhibitors of nitric oxide synthase (NOS) decrease sensitisation in models of persistent pain. The efficacy of inhibitors of NOS has not been tested in patients with tension-type
The efficacy of the inhibitor of nitric oxide synthase, NG-monomethyl-L-arginine hydrochloride (L-NMMA), was tested in 16 patients with chronic tension-type chronic headache. The study was designed as a randomized double-blind, crossover trial. Patients were assigned intravenous infusion of 6 mg/kg
BACKGROUND
Ample evidence that nitric oxide (NO) is a causative molecule in migraine has encouraged research to develop drugs that target the NO-cGMP cascade for migraine treatment. NO synthase (NOS) inhibition is an innovative therapeutic principle.
METHODS
This paper reviews the rationale
Rationale: Mitochondrial encephalomyopathy with lactic acidosis and stroke- like episodes (MELAS) syndrome is caused by mitochondrial respiratory chain dysfunction and oxidative phosphorylation disorder. It is a rare clinical metabolic
OBJECTIVE
To assess whether migraine patients display a chronic nitric oxide synthase (NOS) hyperactivity by comparing the nitric oxide (NO) production before and following a loading dose of L-arginine between migraine patients (interictally) and matched healthy control subjects. In addition, we
