Transcript: SSSRIs Fluoxetine & Fluvoxamine inhibit CYP-1A2, leading to failure to fully metabolize caffeine. Thus those people taking these antidepressants may experience toxicity, intolerance to caffeine, and ‘caffeinism.’ In cigarette smokers, caffeine’s half life is shortened; however, during smoking cessation caffeine’s half-life is extended. This mechanism may exacerbate cigarette withdrawal symptoms by inducing agitation. Energy Drinks Coffee Pills Also Tea and Chocolate (not pictured) Caffeine: the active ingredient By Tracy Markowitz Psychopharmacology Class November 12, 2012 Caffeine and You Caffeine As a vasoconstrictor, can constrict blood vessels thereby decreasing blood flow to the brain by 30% which can produce relief from headaches especially migraines. Caffeine can also produce an antiasthmatic effect or bronchial relaxation Caffeine has been associated with improved glucose tolerance and lower risk of type 2 diabetes Contains antioxidants Also produces alertness & can aid cognitive functioning by delaying fatigue Potential for Abuse The Many and Varied Forms of Caffeine Caffeine is primarily metabolized by the liver. Specifically, the CYP-1A2 enzyme metabolizes caffeine. as caffeine is broken down, metabolizes into theophylline & paraxanthine which behave similarly to caffeine. The third metabolite, theobromide does not produce caffeine like effects. Caffeine’s half-life can be from 2 ½ - 10 hours. Some are predisposed to longer caffeine half-life- taking longer to metabolize caffeine. “Slow metabolizers” may be more susceptible to negative effects of caffeine consumption Negative Pharmacokinetics Positive and Negative Effects of Caffeine Decaffeinated Teas and coffees still contain trace amounts of caffeine (5-15mg) An average cup of coffee contains 100 mg of caffeine Some energy drinks may contain as much as 300 mg of caffeine Treatment of Abuse (?) Caffeine is most often absorbed orally. As caffeine is water soluble, it equally disperses across all parts of the body. Maximum blood levels of caffeine are reached 30-45 minutes after imbibing Half life of caffeine is variable. Adenosine is a neuromodulator While there are not discrete and direct CNS pathways, gradual increase of Adenosine over the course of the day produces sedation by stimulation GABAergic neurons which act as an inhibitor to dopaminergic system Thus, when caffeine BLOCKS adenosine receptors, we see the effects that we all have come to know and love: wakefulness and increased mental acuity. Caffeinism How much is too much? Pharmacokinetics cont’d Adenosine Youtube clip: http://www.youtube.com/watch?v=Xl1XBJLfIDU As previously discussed, caffeine only indirectly stimulates the dopaminergic ‘reward’ system; thus it does not possess the hallmarks of an addictive drug: interaction with nucleus accumbens and involvement in reward motivation and addition While caffeine does not possess the true potential for addiction, consumption of moderate to high levels of caffeine( more than 5 cups of 500 mg/day) will result in tolerance and withdrawal symptoms. Withdrawal symptoms include headache, drowsiness, and fatigue Only mildly behaviorally reinforcing: p. 52 As caffeine is not a true drug of abuse and dependence, there are no formalized treatments specifically designated for caffeine. Over the Counter Medication: Medications such as NoDox contain as much as 200 mg of caffeine per tablet Excedrin contains 75 mg Chewing Gum:Jolt Gum or ThinkGum typically contain 10mg of caffeine per piece Delicious: Chocolate: up to 25 mg per ounce Positive Adenosine’s Job: *Yawn* When intoxicated, caffeine does increases alertness Drinks like Vodka-Redbull or other alcohol & caffeine combinations create the feeling of being wide-awake- drunk As a behavioral stimulant, caffeine increases activity while the motoric and cognitive distortions produced by alcohol remain intact. The End Psychological Agitation Panic Can induce or intensify anxiety disorders Physical Nigh time Wakefulness Tremors Insomnia Gastrointestinal Upset Tachycardia http://www.youtube.com/watch?v=zA0XBKo-NLk Drug interactions On a molecular level, caffeine looks remarkably similar to the endogenous adenosine. Thus it binds to the adenosine receptors and becomes an adenosine antagonist by blocking these recepetors. Symptoms of CNS: Anxiety Agitation Insomnia Symptoms of PNS: Tachycardia Hypertension Cardiac Arrhythmias Gastrointestinal Disturbances Brought on by 500 - 1000mg or roughly 5-10 cups of coffee Most doctors suggest imbibing no more that 3-5 cups per day: For those of you that have forgotten, a cup is 8 ounces… A Grande at Starbucks is 16 ounces 2x 16= 32= some hit this point before doc sem Adds up quickly!

Transcript: Thank You! Caffeine Description Overall Description Caffeine is categorized as a psychostimulant and under drug schedule III. Its main method of use is through food and drink consumption such as coffee, tea, sodas, chocolate, and many others. It is also an ingredient in many over-the-counter medicines. Caffeine has no street names. Caffeine can be obtained through stores, restaurants, bars, and many other places since it is legal. Did you know? Caffeine is consumed daily by 90% of the world's people. Roughly 80% of U.S. adults consume caffeine every day. Short and Long Term Effects - stimulating effect on the central nervous system, heart, blood vessels, and kidneys. -mild diuretic -irritability, nervousness or anxiety -headaches and insomnia -dehydration -delays the time it takes for the consumer to fall asleep and reduces depth and quality of sleep Effects of Caffeine Long Term -dizziness and ringing in the ears -muscle tremors -weakness and fatigue -rapid heart rate and quickened breathing rate -poor appetite, nausea, vomiting and diarrhea -irregular heart rate or rhythm -low blood pressure -confusion or delirium. -increased risk of heart disease Effects on Unborn Child Effects on Pregnancy -It is suspected that a consistent large daily intake of caffeine increases the risks of miscarriages. -2-3 cups of coffee have no effects, while 10 cups or more appear to cause the children after birth to be more fussy and irritable. -It is recommended for pregnant mothers to cut caffeine out completely For context: 14% of caffeine users consume more than 400mg or 4-5 cups of coffee per day. Addiction Withdrawal Addiction and Withdrawal Local and National Help The Mayo Clinic and many other national websites, clinics, or hospitals offer tips on how to cut down on or withdraw from caffeine effectively. If withdrawal ever gets to the point where you are in danger, local help can be any hospital near you or the Pittsburgh Poison Center. Legally and medically, caffeine is not recognized as a dangerously addictive substance. However, although it is not considered addictive there are still mild withdrawal symptoms. Withdrawal is not considered dangerous but more so unpleasant. Listed below are some common caffeine withdrawal symptoms: -headache -marked fatigue or drowsiness -dysphoric, depressed mood or irritability -difficulty concentrating -flu-like symptoms (nausea, vomiting or muscle pain/stiffness). Treatment Methods As mentioned above, many places offer tips on how to effectively withdraw from caffeine. The most common way for caffeine withdrawal is to gradually wean oneself from caffeine in order to minimize any symptoms by tapering off slowly and substituting cups of caffeinated drinks with decaffeinated varieties or other caffeine-free beverages. Withdrawal is not harmful: Only 11% in a case study reported withdrawal symptoms from stopping caffeine intake, and only 3% said their symptoms interfered with daily living. Medical Uses of Caffeine Medical Uses and Legal Risks Caffeine is available by prescription as a solution of caffeine citrate. Caffeine is also an active ingredient in many headache medicines, both by prescription and sold over the counter, as well as in nonprescription aids and herbal preparations for alertness and dieting. Caffeine is also approved as a prescription drug for treating premature infants who are born before their lungs and brain are mature enough for automatic breathing. These babies may have a condition called apnea, in which they cease breathing, which could cause damage to the brain and other organs. Caffeine has been demonstrated to aid in keeping premature babies breathing regularly. There are no legal consequences since caffeine is not a seriously addictive drug and is considered nation-wide as legal. Legal Risks of Caffeine Sources Bibliography American Psychiatric Association.

Transcript: Cons A drug made of the same materials as caffeine... N The question many seem to pose is whether Caffeine is adicitive. So, to answer the question which raged on since 1820, the answer is yes. Why? While you may not be addicted right now, if you take too much Red Bull (5 cans), or a lot of Coca-Cola (unknown), you can get addicted, ergo, proving that over time, with many of its effects, you will be able, eventually causing death, due to overdose. So, while there are positives to caffeine, at the same time, there are a lot of negatives, so remember, be wise to your caffeine! Error 000: The requested information does not exist.
