As youâve probably gathered by now, the light-dependent reactions fuel the second stage of photosynthesis called the light-independent reactions. Our good buddy carbon dioxide (CO 2) provides an excellent source of carbon for making carbohydrates.
A Dr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answered. There are blood pressure medications that do not cause erectile dysfunction (ED). Some older blood pressure medications, especially beta blockers and thiazide diuretics, are the most likely to cause ED as a side effect. Better options include calcium channel blockers, which lower high blood pressure through a different mechanism.
Some medicines can cause blood pressure to drop too low. These include diuretics (water pills), beta blockers (like atenolol [brand name Tenormin] and propranolol [Inderal, Innopran XL, and more]), some Parkinson disease drugs, some antidepressants, and sildenafil (Viagra) and tadalafil (Cialis).
