What does it mean when a drug is centrally acting?
Centrally acting drugs are a type of medicine that can be used to treat high blood pressure. Also known as central alpha antagonists, they work directly on the part of the brain that controls blood pressure. They include clonidine, methyldopa, and moxonidine.
What is a central acting agent?
Central-acting agents lower heart rate and reduce blood pressure. The medicine blocks signals from the brain to the nervous system that increase the heart rate and narrow blood vessels. As a result, the heart doesn’t pump as hard and blood flows more easily through the body’s veins and arteries.
What are the two types of analgesia?
There are two major groups of analgesics: anti-inflammatory analgesics and opioids.
What are centrally acting antihypertensive?
The classic centrally acting antihypertensives such as clonidine, guanfacine and alpha-methyl-DOPA (via its active metabolite alpha-methyl-noradrenaline) induce peripheral sympathoinhibition and a fall in blood pressure as a result of alpha2-adrenoceptor stimulation in the brain stem.
What are centrally acting adrenergic blockers?
Centrally acting antiadrenergic agents inhibit the stimulation of the central nervous system alpha-adrenergic receptors and decrease sympathetic stimulation to the blood vessels and the heart.
What is a centrally acting alpha agonist?
Central alpha agonists are used to treat hypertension, opioid dependence, alcohol addiction, menopause symptoms, ADHD, spasticity, and fibromyalgia. They work by lowering blood pressure, reducing hot flashes, and relieving withdrawal symptoms, and controlling impulsive behavior.
What are the classification of analgesic?
Analgesics may be classified into two types: anti-inflammatory drugs, which alleviate pain by reducing local inflammatory responses; and the opioids, which act on the brain. The opioid analgesics were once called narcotic drugs because they can induce sleep.
Is analgesic and Nsaid same?
It is considered the prototype for anti-inflammatory analgesics, the two other major types of which include acetaminophen (a derivative of phenacetin) and the aspirin-like drugs, or nonsteroidal anti-inflammatory drugs (NSAIDs), which include compounds such as ibuprofen, naproxen, and fenoprofen.
