Synonyms: Anhydrous, Anhydrous Caffeine, Guaranine, Methyltheobromine, Thein,
Manufacturer:
Drug categories: central nervous system stimulant; psychotropic drugs
Pharmacological drug action
Pharmacodynamic
So far no conclusion, only the knowledge to improve the content of intracellular cyclic adenosine monophosphate (cAMP). The role of small doses of the high center of the cerebral cortex, and promote the spirit of excitement, relieve fatigue. Increase the dose of excitement medullary respiratory center and vasomotor center role. Caffeine can also increase the glomerular blood flow to reduce tubular reabsorption, a diuretic effect, but far less than other Potassium Citrate diuretics significantly.
Pharmacokinetic
Gastrointestinal absorption of fast but irregular, fast into the CNS, but also appeared in the saliva and breast milk, no accumulation in vivo. Half-life of α is generally 3.5 hours half-life of β for 6 hours. Plasma concentration and its corresponding peak varies with the amount of generated in the catabolism of methyl uric acid or methyl purine and then with the urine, the urine of only 12 for the prototype.
Indications
Mainly used for the central respiratory and circulatory insufficiency. Patients remain sober; ADHD attention focused therapy; excited breathing, apnea prevention immature newborn children or paroxysmal dyspnea. In combination with ergotamine treatment of migraine marks, and aspirin, acetaminophen made of compound preparations for general headache.
Usage and dosage
