Drug that increases cardiovascular effects is

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a drug that increases cardiovascular effects. This means we are looking for a substance that has a significant impact on the heart and blood vessels.

2. **Analyzing the Options**:
- **Cocaine**: This is a stimulant drug known to increase heart rate and blood pressure. It increases myocardial oxygen demand, which means the heart needs more oxygen to function, leading to increased cardiovascular activity. Additionally, cocaine decreases the diameter of coronary arteries, which can reduce blood flow to the heart muscle.
- **Benzodiazepines**: These are primarily used to treat anxiety and do not significantly affect cardiovascular function. They are more likely to have a calming effect rather than stimulating the cardiovascular system.
- **Barbiturates**: Similar to benzodiazepines, barbiturates are central nervous system depressants and do not enhance cardiovascular effects. They are used for sedation and do not stimulate heart activity.
- **Insulin**: This hormone is used to regulate blood sugar levels and does not have a direct impact on cardiovascular effects. It is not considered a cardiovascular stimulant.

3. **Identifying the Correct Answer**: Based on the analysis, cocaine is the only drug among the options that significantly increases cardiovascular effects by raising heart rate and blood pressure.

4. **Conclusion**: Therefore, the correct answer to the question "Drug that increases cardiovascular effects is" is **Cocaine**.
