A small number of patients also develop renal failure, arthropathy, myopathy, or duodenal ulcer 14). Because the solubility of xanthine is relatively independent of urinary pH, urine alkalinization has no effect (in contrast to patients with uric acid lithiasis) 12). In about half of patients, ultrasonography reveals the presence of xanthine urolithiasis. 2003;326(7386):420. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC149440, K.A. Dark chocolate contains the largest amount of theobromine per serving of any type of eating chocolate; concentrations vary widely (0.36–0.63%) owing to the initial large difference in the theobromine content in chocolate liquors, but one 1-oz bar of dark chocolate contained 130 mg theobromine, and one 1-oz bar of milk chocolate contained 44 mg theobromine. Xanthine is synthesized from guanine in the presence of guanine deaminase. The major pharmacologic actions of the xanthines are inhibition of tissue phosphodiesterases which increases cellular cyclic AMP levels by inhibition of its breakdown and metabolism. NEMJ.

Allopurinol and Febuxostat are xanthine oxidase inhibitor drugs that is used to treat gout and high levels of uric acid in the blood (hyperuricemia) caused by certain cancer medications, and kidney stones. Pregnant women can also safely consume caffeine, however they should consume less caffeine than non-pregnant women, to protect the health of their developing fetus. Methylxanthines are often effective in treating infants with a poor respiratory drive and those experiencing episodes of apnea. Birth Defects Res A Clin Mol Teratol. 2013;11:42. Theobromine is the principal alkaloid (1.5–3%) of the cacao bean (Theobroma cacao); it is usually extracted from the husks of cacao beans, which contain 0.7–1.2% theobromine 41).

Hypoxanthine is a purine and a reaction intermediate in the metabolism of adenosine and in the formation of nucleic acids by the salvage pathway. However, a review of the literature in 2000 demonstrated no evidence of an effect of even moderate to high caffeine consumption on in utero growth 31) and another concluded that low infant birth weight cannot be clearly attributed to caffeine and cannot be separated from effects of other exposures such as maternal smoking and alcohol consumption 32). Bromotheophylline is used as a diuretic and also, in combination with DB00316, it is used for the relief of temporary water weight gain, bloating, swelling and full feeling associated with...
