Propanaol has come up in lectures in my Cell Neuroscience course this sem. Of personal interest to me, as its use has become prevalent in the autism population. My last set of docs at Stanford said they preferred its use as it has less side effects compared to other drugs. I have mixed feelings about it effectiveness in my case but I've heard its helping a number of other autistics.
The use of Propranolol (brand names - Inderal, Hemangeol, & InnoPran XL) in autism is actually off-label as some research has suggested that propranolol may be helpful with anxiety, social withdrawal and repetitive behaviors. More research is needed to fully understand its effectiveness in autism.
One concerning side effect is memory impairment. So I have to wonder about its long term impact as we age, as many autistics are on it for many years and years. Are we looking at short term gains and compromising our long term health compounding health issues that already accompany old age.
