The drug used to increase cardiovascular effects in human beings is

Options

A. Cocaine
B. Barbiturate
C. Benzodiazepine
D. Insulin

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a drug that increases cardiovascular effects in humans. Cardiovascular effects refer to the impact on the heart and blood vessels, including heart rate and blood pressure.

2. **Analyzing the Options**: The options provided include cocaine, barbiturates, benzodiazepines, and insulin. We need to evaluate each option to determine which one increases cardiovascular effects.

3. **Evaluating Cocaine**:
- Cocaine is known to be a powerful stimulant of the central nervous system (CNS).
- It increases heart rate and blood pressure, which are key cardiovascular effects.
- Cocaine can also affect myocardial contractility (the strength of heart contractions).
- While it does have these stimulating effects, it can also lead to harmful cardiovascular conditions such as hypertension and heart disease.

4. **Evaluating Barbiturates**:
- Barbiturates are sedative drugs that act as brain relaxers.
- They do not increase cardiovascular effects; instead, they tend to depress the CNS.

5. **Evaluating Benzodiazepines**:
- Benzodiazepines are also depressants that relax the body and mind.
- Similar to barbiturates, they do not increase cardiovascular effects.

6. **Evaluating Insulin**:
- Insulin is a hormone that regulates blood sugar levels.
- It does not have a direct role in increasing cardiovascular effects.

7. **Conclusion**: After evaluating all the options, the drug that increases cardiovascular effects in humans is **cocaine**.

**Final Answer**: The drug used to increase cardiovascular effects in human beings is cocaine.
