Temporomandibular Joint Disorders | Effect of Propranolol on the Autonomic Nervous System and Muscle Pain
Temporomandibular Joint Disorders research study
What is the primary objective of this study?
The project's primary purpose is to test the hypothesis that oral administration of a low single dose of β-antagonist propranolol (40 mg) reduces pain sensitivity in patients with masticatory muscle pain.
