How are cholinergic agents primarily excreted from the body?

Cholinergic agents are primarily excreted from the body through renal pathways. The kidneys play a crucial role in filtering out waste products and metabolites from the bloodstream, subsequently excreting them through urine. Cholinergic agents, including various medications and their metabolites, are often water-soluble, which enhances their elimination via the renal system.

This renal elimination process is vital for maintaining the body’s pharmacological balance and preventing the accumulation of these agents, which could lead to toxicity. Understanding the renal excretion of cholinergic agents is important for clinicians in adjusting dosages and monitoring patients, especially those with impaired kidney function.

Other excretion routes, such as hepatobiliary pathways, pulmonary excretion, or skin, are not the primary methods for these agents, making renal pathways the most significant for their removal from the body.
