Alpha receptors have two main types: alpha 1 and alpha 2. These alpha receptors play very important roles. Generally, the alpha receptors contribute large effects on our bodyâs systems. With regards to our vascular, smooth muscles, alpha receptors can constrict the vessels of our skin and skeletal muscles.
Alpha blockers work to soothe and calm the muscles. They help in smooth flow of blood by opening the blood vessels. Working of beta blocker drugs is totally different. Instead of having an effect on the muscles, they work to lower the heart rate of a person. Lowering of heart rate has the effect of a corresponding lowering off blood pressure. It is clear then that alpha and beta blockers achieve the same objective through different routes.
