Pharmacological effect

Psychogogic and analeptic, a derivative of methylxanthine. Competitively blocks the central and peripheral A1 and A2 adenosine receptors. Inhibits PDE activity in the central nervous system, heart, smooth muscle organs, skeletal muscles, adipose tissue, promotes the accumulation of cAMP and cGMP in them (this effect is observed when used only in high doses). Stimulates the centers of the medulla oblongata (respiratory and vasomotor), as well as the center of n.vagus, and has a direct stimulating effect on the cerebral cortex. In high doses, it facilitates interneuronal conduction in the spinal cord, enhancing spinal reflexes. It improves mental and physical performance, stimulates mental activity, physical activity, shortens the reaction time, temporarily reduces fatigue and drowsiness. In small doses, the effect of stimulation prevails, and in large doses - the effect of suppression of the nervous system. It stimulates and deepens the breath. Usually it has a positive in-, chrono, batmo-and dromotropic effect (since the effect on the CVS is the direct stimulating effect on the myocardium and the simultaneous stimulating effect on the n.vagus centers, the resulting effect depends on the prevalence of one or another action). Stimulates the vasomotor center and has a direct relaxing effect on the vascular wall, which leads to the expansion of heart vessels, skeletal muscles and kidneys, while the tone of cerebral arteries increases (causes narrowing of the brain vessels, which is accompanied by a decrease in brain blood flow and oxygen pressure in the brain). Blood pressure changes under the action of vascular and cardiac mechanisms of caffeine influence: in normal baseline blood pressure, caffeine does not change or slightly increase it, and in case of arterial hypotension lizuet ego.Okazyvaet spasmolytic effect on the smooth muscles (including bronchodilatory effect) on striated - stimuliruyuschee.Povyshaet secretory activity zheludka.Okazyvaet mild diuretic action,due to reduced reabsorption of sodium ions and water in the proximal and distal renal tubules, as well as expansion of the renal vessels and increased filtration in the renal glomeruli. Reduces platelet aggregation and the release of histamine from mast cells. Increases basal metabolism: increases glycogenolysis, increases lipolysis.

Pharmacokinetics

Data on the pharmacokinetics of the drug is not provided.

Indications

Diseases accompanied by inhibition of the central nervous system, functions of the cardiovascular and respiratory systems (including poisoning with opioid analgesics, infectious diseases), spasms of cerebral vessels, reduced mental and physical performance, drowsiness.

Contraindications

Arterial hypertension, organic diseases of the cardiovascular system (including pronounced atherosclerosis), glaucoma, increased excitability, sleep disturbances, old age.

Precautionary measures

Do not exceed recommended doses.

Use during pregnancy and lactation

C caution is used during pregnancy.

Dosage and administration

Injected s / c or take inside. Adults - 100-200 mg 2-3 times / day; children - 25-100 mg 2-3 times / day.

Side effects

From the side of the central nervous system: sleep disturbance, agitation, anxiety; with prolonged use may be addictive. From the cardiovascular system: tachycardia, increased blood pressure, arrhythmias. From the digestive system: nausea, vomiting.

Overdose

Data overdose of the drug is not available.

Interaction with other drugs

With simultaneous use, the effect of hypnotic drugs and drugs for anesthesia is reduced. With simultaneous use, it is possible to increase the effect of analgesics, antipyretic drugs, salicylamide, naproxen. CYP1A2. With the simultaneous use of adenosine, caffeine reduces the increased heart rate and blood pressure changes caused by infusion of adenosine; reduces vasodilation due to the action of adenosine. With simultaneous use, it is possible to increase the bioavailability, absorption rate and plasma concentration of acetylsalicylic acid. With simultaneous use, meksiletin reduces the clearance of caffeine and increases its concentration in plasma, apparentlydue to inhibition of caffeine metabolism in the liver by meksiletin. Metoksalen reduces the excretion of caffeine from the body with a possible increase in its effect and the development of toxic action. plasma levels of caffeine, ketoconazole, less pronounced. The most pronounced increase in AUC and decrease in clearance are observed I while using caffeine with enoxacin, ciprofloxacin, pipemidovoy acid; less pronounced changes - with pefloxacin, norfloxacin, fleroxacin. When used simultaneously, caffeine accelerates the absorption of ergotamine.
