Acta Anaesthesiologica Scandinavica, 1991
The aim of the present study was to investigate whether the three different caffeine preparations — caffeine citrate, caffeine benzoate and the free base — used forin vitrodiagnosis of malignant hyperthermia susceptibility — produced the same amount of contracture in rat diaphragm.

Current Pain and Headache Reports, 2007
Caffeine is the most widely consumed psychostimulant drug. It is a potent antagonist of adenosine receptors at dosages consistent with common dietary intake. With infrequent exposure, caffeine may act as an analgesic for headache or an adjuvant for the actions of other analgesics. With chronic repetitive intake, caffeine is associated with an increased

Drug and Chemical Toxicology, 1981
While the total annual volume of caffeine has increased over the years, the actual per capita daily intake has not. This is based on the fact that the quantity of caffeine in a soft drink is about the same or, in the case of diet drinks, less than in 1961 when the original GRAS (Generally Recognized as Safe) determinations were made.

Neurology, 1987
Two percent of normal controls noted that drinking coffee made their hands shaky. Eight percent of essential tremor and 6% of Parkinson's disease patients thought that coffee worsened their tremor. In formal tests, a single oral dose of caffeine (325 mg) did not increase physiologic, essential tremor, or parkinsonian tremor at 1, 2, or 3 hours after ...

Survey of Ophthalmology, 2019
Caffeine, a popular psychostimulant that acts as an adenosine receptor antagonist, is the most widely used drug in history, consumed daily by people worldwide. Knowledge of the physiological and pathological effects of caffeine is crucial in improving public health because of its widespread use.

Metamorphosis of caffeine hydrate and anhydrous caffeine
Journal of the Chemical Society, Perkin Transactions 2, 1997The phase stability, interconversion and physicochemical characterisation of caffeine (1,3,7-trimethylpurine-2,6-dione) hydrate and anhydrous caffeine relate to the strength of the available hydrogen-bonds. A hydrogen-bonded T-branched spine of hydrate molecules establishes a weak lattice bond for the caffeine hydrate which, under ambient conditions ...

International Journal of Sport Nutrition, 1995
Caffeine ingestion (3-9 mg/kg body weight) prior to exercise increases performance during prolonged endurance exercise and short-term intense exercise lasting ~5 min in the laboratory. These results are generally reported in well-trained elite or recreational subjects.
