Receptors may result in bronchospasm in some patients. Propranolol has membrane stabilising properties in high doses. It does not have intrinsic sympathomimetic activity (ISA). Propranolol is almost completely absorbed from the GI tract (adults) and there is significant first pass metabolism and hepatic tissue binding with up to 90% of an oral dose being eliminated. At least one metabolite shows biological activity but the effect on overall activity is unknown. Metabolites and a small amount of unchanged propranolol are excreted in the urine. It is widely distributed throughout the body with highest levels occurring in the lungs, kidney, brain and heart. Beta Blockers in the Treatment of Migraine Of all the preventative medicines available across the United States, the drugs known as beta blockers are probably the most frequently prescribed. The "beta" refers to receptors on the blood vessels known as beta receptors. Beta blockers prevent the chemical interaction of certain chemicals with this receptor, hence, the term "beta blockers." Of this family of drugs, the most frequently used drug is Inderal, although others, such as Tenormin and Corgard, will also be used occasionally. Beta blockers were developed primarily for control of cardiac symptoms, but it was found coincidentally that these drugs had a remarkable effect on migraine prevention. After this chance observation was made, studies conducted in the late 1960s and early 1970s confirmed the improvement in migraine with treatment. The studies show that sixty to seventy percent of all migraine subjects experienced a decrease of more than fifty percent in the incidence and severity of their headaches when treated with one of these beta blockers. Two beta blockers are currently FDA approved for use in the preventative treatment of migraine: propranolol (Inderal and Inderal LA) and timolol (Blocadren).
