Routes of Administration Oral Nasal Intramuscular Intravenous Subcutaneous Subcutaneous Topical Buccal Ducal
Bioavailability Absorption
Distribution
Biotransformation Biotransformation Liver enzymes – P450
Elimination
Sites of Action Central Nervous System (CNS) Comprised of the brain and spinal cord Receptor sites on the brain Neurotransmitters
Peripheral Nervous System Somatic Nervous System Autonomic Nervous System – monitors unconscious bodily
functions (fight or flight) Sympathetic (increases heart rate, breathing, etc.) Parasympathetic (reduces heart rate and blood pressure; conserves
energy)
Neurotransmitters (NTs) Neurotransmitters – chemical signals that instruct a
neuron to do something
Neuron – building blocks of the nervous system that receive information from NTs
Excitatory – a NT that tells a neuron to send a message to its targeted cells
Inhibitory – a NT that tells a neuron not to send a message to its targeted cells

Neurotransmitters (NTs) There are several NTs that are relevant to psychoactive chemical abuse:
Acetylcholine
Norepinephrine
Epinephrine
Dopamine Dopamine
Serotonin
Gamma-amino-butyric (GABA)/Glutamate
N-methyl-D-aspartate (NMDA)
Enkephalins, endorphins, and dynorphins
Addiction as a Brain Disease Areas of the brain most likely be affected by substance
abuse include: Old brain New brain Mesolimbic reward pathway Hippocampus (memory) Cerebellum (balance)

Diagnosing Substance Related Disorders
Substance use disorder in DSM-5 combines the DSM-IV categories of substance abuse and substance dependence into a single disorder measured on a continuum from mild to severe
Whereas a diagnosis of substance abuse previously required only one symptom, mild substance use disorder in DSM-5 requires two to three symptoms from a list of 11, moderate substance use denotes an individual meeting 4 to 5 criteria, and severe substance use includes 6 or more criteria met
Diagnosing Substance Related Disorders
Drug craving will be added to the list of symptoms
Problems with law enforcement will be eliminated because of cultural considerations that make the criteria difficult to apply internationally

Central Nervous System Depressants
AlcoholBarbiturates
Benzodiazepines
Alcohol Ethyl alcohol (ethanol) Beer Wine Liquor
Methyl alcohol (methanol) Wood alcohol
Isopropyl (isopropanol) Rubbing alcohol
How Alcohol is Produced Yeast – digests sugar through a process known as fermentation
Yeast breaks down carbon, hydrogen and oxygen in the sugar and in the process produces molecules of ethyl alcohol and carbon dioxide
Distillation
Fortified wines
Hard liquors
Pharmacology of Alcohol Soluble in water and lipids
Main route of absorption is through the small intestine
Biotransformed in the liver
Gastric alcohol dehydrogenase
N-methyl-D-aspartate (NMDA)
Gamma-amino-butyric acid (GABA)
Biotransformation of Alcohol
The liver is the primary site of biotransformation
The liver produces alcohol dehydrogenase (the enzyme necessary in breaking alcohol down) and when it interacts with the alcohol molecule, the metabolite acetaldehyde is produced
The body also produces aldehyde dehydrogenase which breaks down acetaldehyde into acetic acid
Acetic acid is then eliminated from the body
Biotransformation of Alcohol Liver can biotransform one drink every 60 to 90 minutes
Zero-order biotransformation
Alcohol flush Alcohol flush

Middle Stage Loss of control of drinking behavior
I i d i l l i hi Impaired social relationships Morning drinking Neglect of dietary and health needs
Late Stage Must drink in order to function Drinking to avoid withdrawal Nutritional diseases due to high alcohol intake Frequent intoxication Blackouts
Withdrawal Stage I (Tremors)
May occur approximately 8 hours after heavy drinking Usually peaks 24 to 36 hours after the last drink Person experiences tremors, slurred speech, irritability, sweating, increased
blood pressure and heart rate, poor coordination, loss of appetite, etc.
Stage II (Hallucinations) Auditory and/or visual hallucinations Auditory and/or visual hallucinations
Stage III (Withdrawal Seizures) Occurs 7 to 48 hours after the last drink Grand Mal (full body) seizures
Stage IV (Delirium Tremens) Usually occurs 3 to 5 days after last drink 15% fatality rate Profound confusion, severe agitation, reduced psychomotor activity, fever,
dilated pupils, etc.

Central Nervous System Stimulants
AmphetaminesRitalin and Similar Stimulants
CocaineCaffeineNicotineOthers
Amphetamines and CNS Stimulants Gladiators in ancient Rome used stimulants at least 2000
years ago to help them overcome fatigue so they could fight longer; later by truckers, students
Used for treating asthma, sinus problems, headaches, and as a food supplement to assist weight loss and enhance pp gathletic performance
Pharmacology of Amphetamines Primarily affects the peripheral regions of the body
Metabolized by enzymes in the liver and produces the following metabolites: 4-hydroxyamphetamine, 4-hydroxynorephedrine Hippuric acid Benzoic acid
Half-life is estimated at between 2.7 and 3.6 hours

Amphetamines Dextroamphetamine (most common form of amphetamine) Half-life is between 10-34 hours
Methamphetamine Half-life is between 4 to 5 hours Most commonly abused amphetamine Most commonly abused amphetamine Metabolized into amphetamine; similar chemical structure
Amphetamine Methamphetamine
Amphetamines The chemical structure of amphetamine is similar to that
of norepinephrine and dopamine and is classified as an agonist of these neurotransmitters
Amphetamine Norepinephrine Dopamine Amphetamine Norepinephrine Dopamine
Amphetamines The effects of amphetamines depends on several factors Individual’s mental state Dose Potency of the amphetamine Manner in which the drug is used
Cocaine vs. Amphetamines Cocaine effects are shorter than amphetamine Amphetamines are effective when used orally Amphetamines have a very small anesthetic effect
Tolerance develops quickly
Consequences of Abuse Up to 50% of the dopamine producing cells in the brain may
be damaged
Causes the release of large amounts of glutamate which can become toxic and cause neuronal damage and/or death
Incoherent speech
Flat effect

naturally in the khat plant
Produce feelings of joy and increased sociability and sex drive
Individuals who abuse bath salts experience paranoia, agitation, and hallucinations; some even lose contact with reality and act violently; deaths have been reported in several cases
Bath salts are typically swallowed, inhaled, or injected, with the worst dangers being associated with snorting or needle injection
Pharmacology of Cocaine Best absorbed when administered as cocaine
hydrochloride, water soluble compound
Cocaine does not cause the release of dopamine but blocks its reuptake
Tolerance develops within hours or days
Diencephalon – regulates body temp
Nucleus Accumbens – responsible for reinforcing the rewarding effects of a substance

Withdrawal
Withdrawal from cocaine occurs in three phases: Phase I (lasts for several days)
Crash Depression and anxiety Cravings Exhaustion
Phase II (2-3 days to one week) Muscle twitching Irritability Hypersomnia Loss of concentration
Phase III (can last for several years) Intense cravings Marked reduction in ability to enjoy life and pleasurable events
Caffeine Part of the xanthine family of psychoactive chemicals
Most commonly consumed through coffee, soft drinks, and medicines containing caffeine for pain relief (Midol, Excedrine, BC powder)
Can be traced back to Ethiopia around 1000 AD
Caffeine is also used in products such as No-Doz and Red Bull
Caffeine Caffeine works by increasing norepinephrine and blocking
the effects of adenosine, a transmitter that inhibits the release of dopamine and acetylcholine
This allows an increase of dopamine and acetylcholine activity which in turn stimulates the nervous systemactivity, which in turn stimulates the nervous system
It is absorbed in the GI track and its effects can be felt within 30 minutes
Nicotine
Nicotine is a poisonous, oily liquid that comes from NicatinaTabacum, the tobacco plant
In large doses it is highly toxic and has previously been used as an insecticide
It is argued to be the most harmful psychoactive chemical
Pharmacology of Nicotine Nicotine, the active ingredient, was first isolated in 1828
Its effect on the nervous system was known as early as 1889
4700 compounds have been identified in cigarette smoke (2,550 come from the unprocessed tobacco itself)
100,000 other compounds might also be included in the smoke
Pharmacology of Nicotine Pesticides Other organic or metallic compounds Acetone Carbon dioxide Formaldehyde Hydrogen cyanide Lead Tar

Pharmacology of Nicotine Cigarette’s Addictive Properties Each “puff” of the cigarette introduces small doses of
nicotine into the circulation that reaches the brain within 10 seconds (400 doses each day)
The smoker “overlearns” the process of nicotine self-padministration through hundreds or thousands or even millions of repetitions over his or her lifespan
Quickly distributed to every blood-rich tissue in the body
Tolerance begins to develop within as little as a few hours of smoking
Pharmacology of Nicotine Cigarette’s Addictive Properties Water and lipid soluble
Nicotine accumulates in the brain
Affects other NTs including epinephrine (stimulates), dopamine Affects other NTs including epinephrine (stimulates), dopamine (pleasure), MAO (breaks down dopamine), GABA, glutamate, and serotonin

Over-the-Counter Medications
History Willow bark was prescribed by Hippocrates for the
treatment of headache, fever, and labor pain
The active ingredient, salicin, in willow bark was isolated in the 1880s
Salicin was then used to produce salicyclic acid which is easier to produce
Aspirin, also known as acetylsalicylic acid, was originally produced by Bayer Pharmaceuticals
Pharmacology of Aspirin Acetylsalicyclic acid is biotransformed into salicyclic acid
(active ingredient)
Aspirin does not seem to work within the cortex of the brain, but at the site of the injury, in the hypothalamic region, and within the spinal cord
Pharmacology of Acetaminophen Blocks COX-3 synthesis which is causes fever and
inflammation
COX-3 is produced mainly in the CNS, which is where acetaminophen seems to have its main effect
