Effect of stress on the pharmacokinetics of sodium salicylate and quinidine sulphate in rats. 1975

U Otto, and L Paalzow

Studies on the influence of foot shock stress on the absorption, distribution and overall serum elimination of sodium salicylate and guinidine sulphate were performed in rats. Foot shock stress was produced by grid floor electrical stimulation. The animals were stressed 1 hr before administration of the drugs and then throughout the experimental period. A significant induced stress was demonstrated by increased blood glucose levels and increased whole brain turnover of noradrenaline. Gastric emptying and intestinal transit as well as tissue levels of the drugs in the serum, heart, brain, liver, muscle and fat were determined. Results were obtained indicating that stress produced a significant increase in the gastro-intestinal absorption of quinidine sulphate while no change in the distribution pattern of overall elimination was noted. On the other hand, sodium salicylate did not show any marked change in the pharmacokinetic parameters during a stressful situation.

UI	MeSH Term	Description	Entries
D007408	Intestinal Absorption	Uptake of substances through the lining of the INTESTINES.	Absorption, Intestinal
D008297	Male		Males
D009638	Norepinephrine	Precursor of epinephrine that is secreted by the ADRENAL MEDULLA and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers, and of the diffuse projection system in the brain that arises from the LOCUS CERULEUS. It is also found in plants and is used pharmacologically as a sympathomimetic.

D011802	Quinidine	An optical isomer of quinine, extracted from the bark of the CHINCHONA tree and similar plant species. This alkaloid dampens the excitability of cardiac and skeletal muscles by blocking sodium and potassium currents across cellular membranes. It prolongs cellular ACTION POTENTIALS, and decreases automaticity. Quinidine also blocks muscarinic and alpha-adrenergic neurotransmission.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012980	Sodium Salicylate	A non-steroidal anti-inflammatory agent that is less effective than equal doses of ASPIRIN in relieving pain and reducing fever. However, individuals who are hypersensitive to ASPIRIN may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as ASPIRIN, but there is less occult gastrointestinal bleeding. (From AMA Drug Evaluations Annual, 1992, p120)	Salicylate, Sodium
D013312	Stress, Physiological	The unfavorable effect of environmental factors (stressors) on the physiological functions of an organism. Prolonged unresolved physiological stress can affect HOMEOSTASIS of the organism, and may lead to damaging or pathological conditions.
