Miriam Colón SotoKeila Rivera FigueroaIván L. Viera San Martín Drugs used in the Central and Autonomous Nervous System

Introduction : 

Introduction The disease can be treated in different ways according to the affected system. Therapeutic methods through the use of effective medications that treatment will be successful. The nurse must recognize these pharmacological agents and their interaction with the nervous system to carry out a successful intervention to help improve the physical and mental condition of the patient.

Objetivos : 

Objetivos After reading the reader will be able to: Differentiate and explain the roles of central and autonomic nervous system. Explain the action of drugs that can be used to treat nervous system diseases. Describe the benefits and risks associated with their use. To analyze the pharmacokinetics and pharmacodynamics of these drugs in the body.

Cont. Objetivos : 

Cont. Objetivos Analyze and apply appropriate nursing action while the patient receives treatment.

Nervous System Review : 

Nervous System Review The nervous system regulates involuntary bodily activities (eg heart muscle contractions and breathing muscles), quick response to sudden changes in the environment, and the frequency of secretions of certain glands.

Nervous System Review : 

Nervous System Review The brain and spinal cord form the central nervous system (CNS). The CNS receives signals from sensory receptors(vision, pressure, pain, cold, heat, touch, taste) throughout the body that are transmitted to the spinal cord and brain through the afferent nerves.

Nervous System Review : 

Nervous System Review The CNS processes these signals and controls the responses of the body by sending signals through the efferent nerves and then to other body par. Efferent and afferent nerves are the peripheral nervous system. Efferent Afferent

Nervous System Review : 

Nervous System Review The efferent system is divided into:  1.Sistema motor nervous  Controls skeletal muscle contractions.  2. Autonomic nervous system    It helps to regulate functions such as heart rate, blood pressure, temperature control, regulation of light eyes among others

Nervous System Review : 

Nervous System Review Each of the CNS and peripheral nerve is composed of a series of segments known as neurons. A union between a neuron and the next is known as synapses. The transmission of signals or nerve impulses occurs by the chemical activity of some substances known as neurotransmitters.

Importance of neurotransmitters : 

Importance of neurotransmitters Neurotransmitters can inhibit or excite neurons. By the fact that a neuron releases a neurotransmitter, the CNS is composed of different neurons that secrete neurotransmitters separately. Studies indicate that there are about 30 types of neurotransmitters.

Examples of neurotransmitters : 

Examples of neurotransmitters - Acetylcholine- Norepinephrine- Epinephrine- Dopamine- Glycine- Endorphins (regulating pain sensation)- Serotonin (regulates mood)- Prostaglandins- Histamine- Amino Acids

Regulation of neurotransmitte : 

Regulation of neurotransmitte Regulation of neurotransmitters and pharmacological agents (drugs) is a major mechanism by which we can control the diseases caused by excesses or deficiencies of these transmitters.

Autonomic Nervous System : 

Autonomic Nervous System Largely controls the function of tissues. Helps control blood pressure, gastrointestinal motility, urinary function among others. In general, helps to maintain internal balance (homeostasis) and responds to emergency situations.

Definition : 

Definition Drugs used in conjunction with sleep pattern disturbance. A hypnotic drug produces sleep, a quiet place and rest sedative without necessarily drowsy. It is expected that an ideal hypnotic drug has a duration sufficient to enable rest and wake up in good condition for daily activities, but the ideal drug is not available

Sedative hypnotics : 

Sedative hypnotics Currently being used and two non benzodiazepine benzodiazepine. Depending on the frequency of use of benzodiazepines, it is likely that late sleep patterns return to normal

Sedative hypnotics Action : 

Sedative hypnotics Action Produces hypnotic relaxation and sleep. Its effect depends on the dose and patient's condition. Can be classified into three main groups: 1.Barbitúricos 2.Benzodiazepinas 3.No barbiturates
