Question

What are the 4 phases of pharmacokinetics of inhalational agents?

Answer 1

The 4 phases of pharmacokinetics of inhalational agents are absorption, distribution, metabolism, and elimination.

Step-by-step explanation:

The 4 phases of pharmacokinetics of inhalational agents are:

1. Absorption: This phase refers to the process by which the drug enters the bloodstream after inhalation. Inhalational agents are usually absorbed through the alveoli in the lungs and reach the systemic circulation.
2. Distribution: Once in the bloodstream, the drug is distributed to various tissues and organs in the body. This phase determines how the drug is distributed throughout the body.
3. Metabolism: In this phase, the drug is metabolized or broken down by enzymes in the liver and other tissues. Metabolism can lead to the formation of active or inactive metabolites.
4. Elimination: The final phase is elimination, where the drug and its metabolites are excreted from the body. In the case of inhalational agents, elimination primarily occurs through exhalation of the drug.
