- May 22, '11 by MunoRNThere are non-selective beta blockers, such as timolol and propanolol, but they are usually used only as eyedrops to treat glaucoma. "Selective" beta blockers, which aren't 100% selective, particularly at higher doses, are what are typically used. 3rd generation beta blockers (coreg) are actually less selective in that they include some alpha effect.
