Nebivolol is a beta blocker used to treat high blood pressure and heart failure. As with other β-blockers, it is generally a less preferred treatment for high blood pressure. It may be used by itself or with other blood pressure medication. It is taken by mouth.Common side effects include dizziness, feeling tired, nausea, and headaches. Serious side effects may include heart failure and bronchospasm. Its use in pregnancy and breastfeeding is not recommended. It works by blocking β1-adrenergic receptors in the heart and dilating blood vessels.Nebivolol was patented in 1983 and came into medical use in 1997. It is available as a generic medication in the United Kingdom. In 2019, it was the 191st most commonly prescribed medication in the United States, with more than 3 million prescriptions. Medical uses
It is used to treat high blood pressure and heart failure. Nebivolol is used in the treatment of angina, to decrease the heart rate and contractile force. This is relevant in patients who need to decrease the oxygen demand of the heart so that the blood supplied from stenosed or constricted arteries is adequate. ACE inhibitors, angiotensin II receptor antagonists, calcium-channel blockers, and thiazide diuretics are generally preferred over beta blockers for the treatment of primary hypertension in the absence of co-morbidities. Pharmacology and biochemistry
β1-selectivity
Beta blockers help patients with cardiovascular disease by blocking β1 receptors, while many of the side-effects of these medications are caused by their blockade of β2 receptors.
Those present reported carcasses as far as the eye could see. Dead cattle clogged up rivers and spoiled drinking water. Many ranchers went bankrupt and others simply called it quits and moved back east. The "Great Die-Up" from the blizzard effectively concluded the romantic period of the great Plains cattle drives. Schoolhouse Blizzard of 1888 North American Great Plains. January 12–13, 1888. What made the storm so deadly was the timing (during work and school hours), the suddenness, and the brief spell of warmer weather that preceded it. In addition, the very strong wind fields behind the cold front and the powdery nature of the snow reduced visibilities on the open plains to zero. People ventured from the safety of their homes to do chores, go to town, attend school, or simply enjoy the relative warmth of the day. As a result, thousands of people—including many schoolchildren—got caught in the blizzard. Great Blizzard of March 1888 March 11–14, 1888. One of the most severe recorded blizzards in the history of the United States. On March 12, an unexpected northeaster hit New England and the mid-Atlantic, dropping up to 50 in (130 cm) of snow in the space of three days. New York City experienced its heaviest snowfall recorded to date at that time, all street railcars were stranded, and the storm led to the creation of the NYC subway system. Snowdrifts reached up to the second story of some buildings.
