To the Editor.—
Timolol maleate (Timoptic), a topical β-blocking agent for lowering intraocular pressure, has gained widespread acceptance as a safe and effective drug. Since its introduction, various side effects have been reported, albeit at an acceptable incidence.1 Most of the systemic side effects described are common to all β-blockers and are presumably the result of absorption into the circulation. Uncommon but recognized side effects of this group include depression, paranoia, and psychosis.2 Although mild CNS effects have been reported with timolol, including anxiety, disorientation, fatigue, and anorexia, major reactions have not been noted. A case of acute suicidal depression thought to be directly related to the use of timolol at normal dosage is described.
Report of a Case.—
