is caffeine a drug

The average cup of coffee contains 150-200 milligrams (mg) of caffeine per cup, while a cup of tea will have about 60 mg of caffeine. [7], Because caffeine is both water- and lipid-soluble, it readily crosses the blood–brain barrier that separates the bloodstream from the interior of the brain. Caffeine is not listed as having a drug interaction with the atypical antipsychotic medicine Vraylar (generic name: cariprazine). [188] Common sources are the "beans" (seeds) of the two cultivated coffee plants, Coffea arabica and Coffea canephora (the quantity varies, but 1.3% is a typical value); and of the cocoa plant, Theobroma cacao; the leaves of the tea plant; and kola nuts. [132] For example, when additional caffeine is added, the drug effect produced by alcohol is not reduced. [162], Caffeine's biological half-life – the time required for the body to eliminate one-half of a dose – varies widely among individuals according to factors such as pregnancy, other drugs, liver enzyme function level (needed for caffeine metabolism) and age. [139] Antagonism of A2A receptors in the ventrolateral preoptic area (VLPO) reduces inhibitory GABA neurotransmission to the tuberomammillary nucleus, a histaminergic projection nucleus that activation-dependently promotes arousal. [clarification needed][174][175][179], Commercial supplies of caffeine are not usually manufactured synthetically because the chemical is readily available as a byproduct of decaffeination.[180]. Caffeine is a naturally occurring psychoactive substance with stimulant properties. "[252], Gaudiya Vaishnavas generally also abstain from caffeine, because they believe it clouds the mind and over-stimulates the senses. [122] In 2016, 3702 caffeine-related exposures were reported to Poison Control Centers in the United States, of which 846 required treatment at a medical facility, and 16 had a major outcome; and several caffeine-related deaths are reported in case studies.

In 1819, Runge was invited to show Goethe how belladonna caused dilation of the pupil, which Runge did, using a cat as an experimental subject. Therefore, the fused 5,6 ring core of caffeine contains a total of ten pi electrons and hence according to Hückel's rule is aromatic. It reaches its highest … [63] Other reviews, however, concluded that there is some evidence that higher caffeine intake by pregnant women may be associated with a higher risk of giving birth to a low birth weight baby,[64] and may be associated with a higher risk of pregnancy loss.

[159] Caffeine can also be absorbed rectally, evidenced by suppositories of ergotamine tartrate and caffeine (for the relief of migraine)[160] and of chlorobutanol and caffeine (for the treatment of hyperemesis). Drug class(es): antimigraine agents Caffeine/ergotamine systemic is used in the treatment of: Cluster Headaches; Migraine; caffeine/magnesium salicylate systemic. The scientific name for caffeine is 1,3,7-trimethylxanthine. Once in the brain, the principal mode of action is as a nonselective antagonist of adenosine receptors (in other words, an agent that reduces the effects of adenosine). To report side effects to the appropriate agency, please read the Guide to Reporting Problems to FDA. Caffeine in powder or liquid form can provide toxic levels of caffeine, the U.S. Food and Drug Administration has cautioned. It is found in the seeds, nuts, or leaves of a number of plants native to Africa, East Asia and South America,[12] and helps to protect them against herbivory and from competition by preventing the germination of nearby seeds. Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and guanine bases of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). When caffeine is consumed, it antagonizes adenosine receptors; in other words, caffeine prevents adenosine from activating the receptor by blocking the location on the receptor where adenosine binds to it. According to DSST, alcohol provides a reduction in performance and caffeine has a significant improvement in performance. Caffeine may also be used for other conditions as determined by your health care provider. [60] Energy drinks are more commonly consumed as a source of caffeine in adolescents as compared to adults. It is true that—like many drugs—caffeine enhances dopamine signaling in the brain. [18][19] Caffeine can produce a mild form of drug dependence – associated with withdrawal symptoms such as sleepiness, headache, and irritability – when an individual stops using caffeine after repeated daily intake. More frequently reported side effects include: necrotizing enterocolitis. Do not double-up on your caffeine dose if you should miss the time for next dose. [168] Caffeine does not contain any stereogenic centers[169] and hence is classified as an achiral molecule. [206] By contrast, energy drinks, such as Red Bull, can start at 80 milligrams of caffeine per serving. [54] A 2017 systematic review on caffeine toxicology found evidence supporting that caffeine consumption up to 300 mg/day for pregnant women is generally not associated with adverse reproductive or developmental effect. Generic Name: Caffeine Caffeine is the most widely used psychoactive substance in the world. Is Caffeine a Drug?

According to the DSM-5, caffeine intoxication may be diagnosed if five (or more) of the following symptoms develop after recent consumption of caffeine: restlessness, nervousness, excitement, insomnia, flushed face, diuresis (increased production of urine), gastrointestinal disturbance, muscle twitching, rambling flow of thought and speech, tachycardia (increased heart rate) or cardiac arrythmia, periods of inexhaustibility, and psychomotor agitation. Other disorders that present with significant distress and impairment of daily functioning that warrant clinical attention but do not meet the criteria to be diagnosed under any specific disorders are listed under “Unspecified Caffeine-Related Disorders”. With a continued wakeful state, over time adenosine accumulates in the neuronal synapse, in turn binding to and activating adenosine receptors found on certain CNS neurons; when activated, these receptors produce a cellular response that ultimately increases drowsiness. [225] According to Runge, he did this at the behest of Johann Wolfgang von Goethe. Select one or more newsletters to continue.
