Study Notes
CNS DEPRESSANTS ANXIOLYTICS AND HYPNOTICS CNS STIMULANTS
- Anxiety is a feeling of tension, nervousness, apprehension or fear involving unpleasant reaction to stimuli.
- Sedation is the loss of awareness and reaction to environmental stimuli.
- Hypnosis is the reduction of awareness and reaction to environmental stimuli without loss of consciousness.
- Anesthetics are drugs used to produce a state of anesthesia.
- Anesthesia is the loss of sensation or the feeling of pain.
- Local Anesthetics block pain at the site where the drug is administered.
- General Anesthetics are administered intravenously or inhaled, resulting in a loss of consciousness.
STAGES OF ANESTHESIA
- Analgesia is the first stage where patient begins awake and ends with loss of consciousness where the patient experience loss of pain sensation.
- Stage 2, is the excitatory stage marked by excitement and delirium and increase in vital signs.
- Stage 3 the surgical stage, patients' vitals are stable and there is muscle relaxation.
- Stage 4 is the overdose stage, marked by severe respiratory depression and circulatory failure.
DRUGS FOR NEUROMUSCULAR DISORDERS
- Myasthenia Gravis is a chronic autoimmune neuromuscular disease that impairs transmission of nerve impulses at the neuromuscular junction.
- Myasthenia gravis is caused by the destruction of acetylcholine receptors at the neuromuscular junction, resulting in decreased acetylcholine transmission to muscles.
DRUGS FOR ABSENCE SEIZURES (PETIT MAL)
- Succinimides are used for absence seizures (petit mal).
- Ethosuximide (Zarontin) is a first-line drug for absence seizures.
- Succinimides can cause bone marrow suppression, so it is important to monitor white blood cell counts.
DRUGS FOR MUSCLE SPASMS/ MUSCLE RELAXANTS
- Muscle spasms are caused by the overstretching of a muscle, tearing a tendon or ligament, or cutting off blood flow to the muscle fibers.
- Muscle spasticity is caused by damage to neurons in the central nervous system.
- Muscle spasms and spasticity can lead to pain, contractures, and permanent disability.
DRUGS/MANAGEMENT FOR MS
- Glucocorticoids are used for acute attacks of multiple sclerosis (MS).
- Amantadine (Symmetrel) and bromocriptine mesylate (Parlodel) are dopamine agonists used to increase mobility and decrease rigidity in MS patients.
ALZHEIMER'S DISEASE
- Alzheimer's disease is a progressive neurodegenerative disease that causes memory loss and cognitive decline.
- The drug of choice for Alzheimer's disease is donepezil (Aricept), a cholinesterase inhibitor.
- Other medications used for Alzheimer's disease include galantamine (Razadyne), memantine (Namenda), and rivastigmine (Exelon).
- Memantine is an NMDA antagonist, a glutamate receptor, that play's an important role in synaptic plasticity, believed to be the basis of memory formation.
