Uptake into tissue causes the blood concentration to fall. Absorption from the gut diminishes as the mucosa-blood gradient decreases. Plasma concentration reaches a peak when the drug amount leaving the blood per unit of time equals that being absorbed. Drug entry into hepatic and renal tissue constitutes movement into the organs of elimination.

 

The side effects of tricyclic antidepressants are largely attributable to the ability of these compounds to bind to and block receptors for endogenous transmitter substances. These effects develop acutely. Antagonism at muscarinic cholinoceptors leads to atropinelike effects such as tachycardia, inhibition of exocrine glands, constipation, impaired micturition, and blurred vision.
The immediate threat results not so much from the loss of erythrocytes, i. e. , oxygen carriers, as from the reduction in volume of circulating blood. To eliminate the threat of shock, replenishment of the circulation is essential. With moderate loss of blood, administration of a plasma volume expander may be sufficient. Blood plasma consists basically of water, electrolytes, and plasma proteins.
