The secretion was inhibited by propranolol (1 mg/kg) and metoprolol (10 mg/kg) but not by phenoxybenzamine (2 mg/kg) and atropine (25 μg/kg). The results indicate that the sympathetically induced secretion in the rabbit lacrimal gland occurs through an adrenergic mechanism. The adrenergic receptors in the lacrimal gland is most likely of β1-type. © 1984.Mahidol UniversityPharmacology, Toxicology and PharmaceuticsArticleSCOPUS10.1016/0024-3205(84)90424-7
