Abstract:
Prostaglandin E analogs have been shown to be effective in the treatment of refractory trigeminal neuralgia in patients with multiple sclerosis. Prostaglandin E inhibits the functions of T lymphocytes which are involved in the pathophysiology of cluster headache. Therefore, a double-blind, placebo-controlled, crossover study on the efficacy of misoprostol in chronic refractory cluster headache was performed. Eight patients were treated with 600 micrograms misoprostol and with placebo for a 2-week period. No differences in attack frequency, intensity, global impression, and side effects could be detected, suggesting that prostaglandin E analogs are not effective in the treatment of chronic cluster headache.

These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
