General anesthetics

General anesthetics

General anesthetics are medicines that render a patient reversibly unconscious and unresponsive in order to allow surgeons to operate on that patient. 
General anesthetics are normally administered intravenously or by inhalation by a specialist doctor called an anesthetist who also monitors the patient's vital signs (breathing, heart rate, blood pressure, temperature) during the procedure. 
While under general anesthesia, a patient is unable to feel pain and will likely wake with some short-term amnesia (memory loss). Experts are unsure exactly how general anesthetics work.

Ketamine:

  • It is used to cause sleep during care.
  • It is used to put you to sleep for surgery.
  • It may be given to you for other reasons. Talk with the doctor.
Propofol
Propofol (Diprivan) slows the activity of your brain and nervous system.
Propofol is used to help you relax before and during general anesthesia for surgery or other medical procedures.
Propofol is also used to sedate a patient who is under critical care and needs a mechanical ventilator (breathing machine).
Thiopental
Thiopental is a barbiturate (bar-BIT-chur-ate). Thiopental slows the activity of your brain and nervous system.
Thiopental is used to help you relax before you receive general anesthesia with an inhaled medication.

Anorexiants

What are Anorexiants? Anorexiants are drugs that act on the brain to suppress appetite. They have a stimulant effect on the hypothalamic and limbic regions, which control satiety. Anorexiants are used as therapy for obesity. Phendimetrazine Phendimetrazine is a sympathomimetic amine, which is similar to an amphetamine. It is also known as an "anorectic" or "anorexigenic" drug. Phendimetrazine stimulates the central nervous system (nerves and brain), which increases your heart rate and blood pressure and decreases your appetite. Phendimetrazine is used as a short-term supplement to diet and exercise in the treatment of obesity.   Phendimetrazine may cause blurred vision or impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly. Phendimetrazine may be habit-forming and should be used only by the person it was prescribed for. Keep the medication in a secure place where others cannot get t...

Anticonvulsants

What are Anticonvulsants? Anticonvulsants (antiepileptics or AEDs) helps to normalise the way nerve impulses travel along the nerve cells which helps prevent or treat seizures. When the brain is working normally the nerve cells talk to each other using controlled electrical signals from one nerve cell to another. This tells the body to do everything it needs or wants to do. During a seizure there is a change in the level of nerve cell electrical signals from a normal level to an excessive or abnormal amount of nerve signals. This increased nerve activity is responsible for the signs and symptoms of a seizure. What causes the change is nerve impulses can be the result of an injury to part of the brain, stroke, brain tumor, genetic causes, metabolic problems or toxicity issues. Anticonvulsants can also be used to treat nerve pain and bipolar disorder. How they work? Anticonvulsants keep the nerve cell impulses to a normal level so they don’t become excessive and uncontrolled, w...

Anxiolytics, sedatives, and hypnotics

Anxiolytics, sedatives, and hypnotics Anxiolytics, sedatives and hypnotics are medicines that work on the central nervous system to relieve anxiety, aid sleep, or have a calming effect. The benzodiazepines are the main class of drugs that fit into this category . Although there are more than twenty benzodiazepine derivatives, only certain ones have been approved to treat anxiety (eg, alprazolam, clonazepam, diazepam, and lorazepam ), sleeplessness (insomnia) (eg, estazolam, flurazepam, quazepam, temazepam and triazolam), or panic disorder (eg, alprazolam). Barbiturates are an older class of medicine that used to be used for these indications as well; however, barbiturates have a narrow therapeutic index (window of effectiveness before toxicity occurs), and are more likely to cause respiratory depression, coma and death, and are very rarely used nowadays. The main issue with use of benzodiazepines is dependence. Benzodiazepines differ in their propensity to cause sedation and in th...
