How Do Sleeping Pills Work?

Author: Eric Cho
Sleeping pills are sedatives that depress the central nervous system of the human body. This results in tranquility, relaxation, less anxiety, sleepiness, slowed breathing, slurred speaking, staggering gait, poor judgment and slow, uncertain reflexes. They are also called downers, tranquillizers, depressants, anxiolytics, soporifics or sedative hypnotics.

Most sleeping pills are usually prescribed for patients with anxiety problems. However, those described as sedatives are also used to help people sleep. Long term use of sleeping pills is discouraged as they are addictive and could be dangerous to the health of the patient.

The human body has two basic drives which is the waking drive and the sleeping drive. During the day, the waking drive is strong and the brain remains active. As the day wears on, the waking drive becomes weaker and the sleeping drive strengthens. As evening approaches, the sleeping drive builds up and by the time night approaches, the body is ready to go to sleep. What a sleeping pill does is that it strengthens the sleeping drive in the human body. A person with insomnia has imbalanced sleeping and waking drives.

In normal people, the onset of darkness induces the pineal gland in the brain to secrete a hormone called melatonin which prompts the body to go into the sleep drive. The melatonin makes the body less alert, it slows down the body mechanisms and the person begins to feel the need to sleep. The action of sleeping pills is similar. It sends signals to the brain that approximate to the symptoms produced by the hormone melatonin. The central nervous system is dampened and its ability to function is diminished. This makes the person sleepy. Sleeping pills work less effectively when the patient has had long term insomnia or has had trouble staying asleep for a long time.

Most sleeping pills are Benzodiazepines. Benzodiazepines are minor tranquilizers that belong to a class of drugs that are used to induce sleep. There are several drugs such as Nitrazepam, Loprazolam and Flurazepam that are categorized under Benzodiazepines. However, benzodiazepines are also used to tackle problems relating to anxiety, epileptic seizure and amnesia and it is important to choose the right benzodiazepine as a sleeping pill. Some of the trade names of benzodiazepines drugs are Mogadon, Remnos and Somnite. The natural herb Mandrake is also a common ingredient in these drugs. Mandrake is traditionally known as a drug that helps people sleep.

However, there are possibilities of side effects when taking sleeping pills. Most benzodiazepines have the same side effects- headaches, drowsiness, light-headedness, unsteadiness, confusion, forgetfulness, dependence, withdrawal, increase in aggression and muscle weakness. There are many drugs that one might be consuming that may interfere with the effectiveness of sleeping pills. These drugs themselves may be sleep inducing and taking sleeping pills in addition to such drugs will result in the effect of these pills lasting longer. People with respiratory problem, muscle problems, a history of drug or alcohol abuse or personality disorder, who are consuming sleeping pills, are advised to use it with caution and to consult their physician before taking any sleeping pill.

Moreover, some sleeping pills are known to cause amnesia. Patients have been known to perform several physical activities-even going on a binge on food-while completely asleep under the effects of the sleeping pill. Patients must, therefore, ensure that the instructions are followed meticulously and go to bed immediately after taking the sleeping pill.

Signs and Symptoms of Heart Attack

A lot is written about the so called common signs of Heart Attacks and what they are supposed to typically consist of but what is fact and what is fiction? Here we take a look at the basic issues surrounding Heart Attacks or Myocardial infarctions.
A Heart Attack is also known as a Myocardial Infarction or MI or AMI when referred to as an Acute Myocardial Infarction.These occur when the blood supply to part of the heart is interrupted causing some heart cells to die. This is most commonly due to occlusion (blockage) of a coronary artery following the rupture of a vulnerable atherosclerotic plaque.An unstable collection of white blood cells (especially macrophages and lipids (like cholesterol) collectively known as Athersclerotic plaque separate from the wall of an artery.The end result of all of this (called ischemia) which is a restriction in blood supply) has been known to cause damage or death of the heart muscle tissue known as Myocardium.

Though symptoms of a Heart Attack do differ there are certain classic symptoms such as shortness of breath, nausea, vomiting, pain in the arm, back and neck, and a growing sense of anxiety (also known as impending doom). Women may experience fewer typical symptoms than men, most commonly shortness of breath, weakness, a feeling of indigestion, and fatigue.{Approximately one quarter of all myocardial infarctions are silent, without chest pain or other symptoms.|It does have to be remembered though that 25 percent of all Myocardial Infarctions occur in silence and without classic symptoms such as chest pain.A heart attack is a medical emergency, and people experiencing chest pain are advised to alert their emergency medical services, because prompt treatment can be crucial to survival. To be quite honest in situations like these, minutes and seconds do matter.

Heart attacks are the leading cause of death for both men and women all over the world.Important risk factors are previous cardiovascular disease (such as angina, a previous heart attack or stroke), older age (especially men over 40 and women over 50), tobacco smoking, diet and exercise.

As is also imagined there are considerably more factors that are actually taken into consideration such as additional medical conditions of which potential or actual diabetes is one, obesity, high blood pressure or hypertension and/or incidence of kidney disease

Included in amongst immediate treatment for a suspected or acute heart attack is increased oxygen, the introduction of aspirin and also a liquid form of nitroglycerin known as sublingual glyceryl trinitrate.Pain relief is also often given, classically morphine sulfate.
