Doctors' Answers to "Frequently Asked Questions" - Persantine
Persantine for Treatment of Stroke
Answer: Most physicians consider this drug worthless for stroke prevention. However, the options in women are limited since aspirin is of limited/no value in women (very effective in men) and the only option is Ticlid which is expensive and has some potential severe side effects. If you don't have documented TIAs and/or significant vascular disease, I wouldn't use Ticlid due to the risk/benefit ratio. There currently is no drug in women which has low side effects and is effective. Consequently, some physicians use Persantine, but the studies show marginal benefit at best.
Answer: Floaters are caused by debris in the vitrous of the eye. This is almost always from the retina and may occur spontaneously or as a result of trauma. These floaters will not go away since they represent cells floating in the liquid part of the eye. The eye has no ability to filter or remove these cells. Persantine stress tests are administered when the person is physically or mechanically unable to perform a treadmill or bicycle exercise load. This is usually due to severe lung disease or severe limiting conditions of the legs which limit the ability to walk. Persantine loads the heart and produces an artificial load which is then followed by the EKG. There are side effects and these should he explained in detail prior to the test. Like any stress test, there have been major problems-inclu(ling death-and they should not be performed lightly. Whether this was due to the persantine is not clear. There is an adverse drug reaction form available from the NlH-l'd recommend that your doctor fill one out. This does not imply that the cause was persantine;but, does give an information base to the NIH to follow unusual or uncommon reactions.
