response to acute stress‚ acetylcholine is released from preganglionic sympathetic nerves that innervate the chromaffin cells of the adrenal medulla. As a consequence‚ the chromaffin cells secrete the hormone epinephrine (adrenaline) into the general circulation. This provides readily available sources of energy by forming glucose from glycogen depots and [[free fatty acid]s from the triglyceride stores of adipose tissue; it quickens the pulse and raises arterial blood pressure‚ but also accelerates blood

Prerenal failure is characterized by inadequate blood circulation to the kidneys‚ which leaves them unable to clean the blood properly. Many patients with prerenal failure are critically ill and often experience shock. There is often poor perfusion within many organs‚ which may lead to multiple organ failure.

eliminated. The absorption of the drug depends on first pass metabolism and bioavailability. First pass metabolism refers to “the elimination that occurs when a drug is first absorbed from the intestine and passes through the liver via the portal circulation”. The liver is the primary drug metabolizing organ in the body. Drugs that are easily metabolized have a large first pass effect and low bioavailability. [1] Drugs that are orally administered are mostly affected by first pass metabolism as

Thirst is the craving for liquids‚ resulting in the basic instinct of humans or animals to drink. It is an essential mechanism involved in fluid balance. It arises from a lack of fluids and/or an increase in the concentration of certain osmolites such as salt. If the water volume of the body falls below a certain threshold‚ or the osmolite concentration becomes too high‚ the brain signals thirst. Continuous dehydration can cause a myriad of problems‚ but is most often associated with neurological

Formoterol has a long-acting effect. Budesonide is a corticosteroid which controls the rate of protein synthesis‚ depresses the migration of polymorphonuclear leukocytes/fibroblasts‚ and reverses capillary permeability and lysosomal stabilization at the cellular level to prevent or control inflammation
