Analgesic describes medications specially formulated for alleviating pain. Certain analgesics are available for purchase over-the-counter, while many are only available to buy with a prescription. Some analgesic medications blend two drugs in the analgesic class for enhanced relief. An individual has certain receptors on the cells in their spinal cord, brain, and gastrointestinal tract that help relay pain signals throughout the body. Analgesics work by taking advantage of these receptors and binding to them. This mechanism stops pain signals from reaching the brain. Analgesics are used in individuals who have moderate to severe chronic or acute pain. Analgesics are viable for individuals who cannot utilize nonsteroidal anti-inflammatory drugs because they do not produce gastrointestinal bleeding.
Of course, analgesics may produce adverse side effects in some individuals. Get the details on these now.
Some individuals who take acetaminophen or opioid-based analgesics may experience an upset stomach and nausea. An upset stomach is the result of the activity of the medication that involves the activation of the chemoreceptor trigger zone and the individual's gastric motility. The dopamine receptors in the chemoreceptor zone are critical to the triggering mechanism that causes nausea and stomach upset. A decrease in gastric motility can cause food to back up in an individual's digestive system, allowing it to rot in the digestive organs and cause stomach upset. Some patients experience an increase in the sensitivity of their vestibular system, which manages balance. Increased vestibular sensitivity causes the affected individual to feel nausea and an upset stomach. Nausea and vomiting is a relatively common side effect of analgesics, and more so for those that combine acetaminophen with another medication.
