Theophylline (4%): Relaxes smooth muscles of the bronchi, and is used to treat asthma. The therapeutic dose of theophylline, however, is many times greater than the levels attained from caffeine metabolism.

During the same period– while they were searching for quinine in coffee because coffee is considered by several doctors to be a medicine that reduces fevers and because coffee belongs to the same family as the cinchona [quinine] tree– on their part, Messrs. Pelletier and Caventou obtained caffeine; but because their research had a different goal and because their research had not been finished, they left priority on this subject to Mr. Robiquet. We do not know why Mr. Robiquet has not published the analysis of coffee which he read to the Pharmacy Society. Its publication would have allowed us to make caffeine better known and give us accurate ideas of coffee's composition... a b c d e f g h i j k l m n o p "Caffeine". DrugBank.

The same amount of Mountain Dew contains 55 mg caffeine.

Those who consumed more than 450 mg daily had a significantly increased risk of incontinence, compared to those who consumed less than 150 mg per day ( 45). Robiquet was one of the first to isolate and describe the properties of pure caffeine, [262] whereas Pelletier was the first to perform an elemental analysis. [263] A 2011 review found that increased caffeine intake was associated with a variation in two genes that increase the rate of caffeine catabolism. Subjects who had this mutation on both chromosomes consumed 40mg more caffeine per day than others. [192] This is presumably due to the need for a higher intake to achieve a comparable desired effect, not that the gene led to a disposition for greater incentive of habituation.

Withdrawal can cause mild to clinically significant distress or impairment in daily functioning. The frequency at which this occurs is self-reported at 11%, but in lab tests only half of the people who report withdrawal actually experience it, casting doubt on many claims of dependence. [121] Mild physical dependence and withdrawal symptoms may occur upon abstinence, with greater than 100mg caffeine per day, although these symptoms last no longer than a day. [2] Some symptoms associated with psychological dependence may also occur during withdrawal. [6] The diagnostic criteria for caffeine withdrawal require a previous prolonged daily use of caffeine. [122] Following 24 hours of a marked reduction in consumption, a minimum of 3 of these signs or symptoms is required to meet withdrawal criteria: difficulty concentrating, depressed mood/ irritability, flu-like symptoms, headache, and fatigue. [122] Additionally, the signs and symptoms must disrupt important areas of functioning and are not associated with effects of another condition. [122]
