Ethmozine and Glaucoma
Question:I have been taking moricizine hydrochloride about 2 years. It has completely controlled my atrial flutter. Last August, at my annual eye exam, intraocular pressure was slightly elevated and was again last week. I suspect the moricizine of causing the increase in pressure to ca. 23. Moricizine
reduces sodium flux in cardiac muscle tissue could it some-how alter the steady state intraocular fluid? I am taking 1 drop/eye daily of 0.5% timoptic, a beta-blocker. In that low dosage, I am experiencing lowered resting pulse (from 60 to 52), dizziness upon standing quickly, reduced libido, and slight depression. I went on moricizine to get away from the crushing effect of a beta blocker (sotolol) taken orally. Now the moricizine may be forcing me back into the same situation.
Answer:Ethmozine(moricizine hydrochloride) is a relatively new anti-arrhytmic drug. It is used in controlling different irregular heart rythms. I could find no reports of causing glaucoma. However, with a new drug-used in smaller numbers of patients this may or may not he accurate. I would ask your physician to file a drug interaction report. This does not indict the drug;but, does establish a data base in case many cases of glaucoma are reported. Stopping the drug-if cleared by your physician-would be one way to check this. However, I think there should not be a causal relationship. Beta-blockers are very effective in treating glaucoma. However, about 5-10% of patients will experience the systemic effects of beta-blocker eye drops. Eye doctors and the companies are always startled by this and usually deny any interaction. However, this is my experience with my patients. I doubt the moricizine is causing this problem. You should ensure that your Internist or Cardiologist is aware that you are on beta blocker eye drops.
