Central Nervous System (CNS)
What disease occurs when a brain disorder causes unintended or uncontrollable movements, such as shaking, stiffness, and difficulty with balance and coordination?
Parkinson’s Disease
Two types of DRUGS DEPLOYED
Dopaminergic drugs and Anticholinergic Agents
How does CNS depressant produce
An agent which decreases the excitability of tissue in the CNS
-Produces sedation, hypnosis, general anesthesia, coma, death
- All drugs in this category can act as sedatives, hypnotics, or general anesthetics - depending upon the dose given
This drug is to prevent seizures
Anticonvulsant Drugs
Anticonvulsant Drug Physiology
To suppress the abnormal electrical impulses from the seizure area of the brain to other areas

-Caffeine - coffee beans, tea leaves, kola nuts
-Theophylline - tea leaves
-Theobromine - cocoa
What is a general anesthetic?
A drug that causes loss of consciousness
Partial seizures
It is a seizure in that excitation undergoes limited spread from the focus to adjacent cortical areas
Anticonvulsant Drug Physiology

This barrier impedes the entry of drugs into the brain.
Blood-brain Barrier
Sedative hypnotics may be classified as
Barbiturates or non-barbiturates
Trauma, idiopathic, infection, toxins & metabolic factors
Reason for Seizures
Doxapram
It’s a drug that treats respiratory depression caused by drug overdose and COPD (Chronic obstructive pulmonary disease)
Generalized seizures
Is a type of seizure that excitation spreads widely throughout both hemispheres of the brain
What is NEUROPHARMACOLOGY?
Study of drugs that alter processes controlled by the nervous system
It is a state in which abrupt discontinuation of drug use will precipitate a withdrawal syndrome
Physical Dependence
It is the most commonly prescribed anticonvulsant medication
PHENYTOIN
Methylphenidate and modafinil
CNS drug that treats narcolepsy
_______ is used to treat and prevent seizures. This medication is known as an anticonvulsant or anti-epileptic drug. It also aids in the relief of some types of nerve pain (such as trigeminal neuralgia).
