Question

Identify five different ways that drugs can enter the body.

Answer 1

There are five main ways that drugs can enter the body: inhalation, injection, ingestion, absorption, and dissolution. Each route has its advantages and considerations.

Step-by-step explanation:

There are multiple ways that drugs can enter the body:

1. Inhalation: Drugs can be inhaled by breathing in substances such as smoke, fumes, or vapors. Examples include smoking cigarettes or using an inhaler for asthma.
2. Injection: Drugs can be injected into the body using a needle and syringe. This can be done intravenously (directly into a vein), intramuscularly (into a muscle), or subcutaneously (under the skin). Examples include administering vaccines or taking insulin for diabetes.
3. Ingestion: Drugs can be taken orally by swallowing them. This is the most common route of drug administration. Examples include taking medication in pill or liquid form.
4. Absorption: Drugs can be absorbed through the skin or other mucous membranes. This can occur with patches, creams, or suppositories. Examples include using nicotine patches for smoking cessation or applying a topical pain relief cream.
5. Dissolution: Some drugs can be dissolved under the tongue. This is called sublingual administration. Examples include taking certain medications for heart conditions or headaches.
