pubmed-article:15183593 | pubmed:abstractText | Imidazoline derivatives like naphazoline have a firm place in diagnostics and therapy of otorhinolaryngology because of their vasoconstrictive and decongestive properties. Their alpha-adrenergic potential could induce not only local but also systemic side effects like hypertension and tachycardia which can increase a life-threatening intoxication. Signs of imidazoline intoxication are excessive systolic and diastolic hypertension and hypotension, bradycardia with arrhythmia, respiratory depression, excitation or severe CNS depression. | lld:pubmed |
