While antacids and antiallergic drugs interfere with the function of histamines, why do these not interfere with the function of each other ?

Explanation

### Step-by-Step Solution:

1. **Understanding Histamines**: Histamines are organic compounds involved in local immune responses and act as neurotransmitters. They bind to specific receptors in the body to exert their effects.

2. **Role of Antacids**: Antacids are substances that neutralize stomach acid. They do not directly interact with histamine receptors but can influence the effects of histamines related to gastric acid secretion.

3. **Role of Antiallergic Drugs**: Antiallergic drugs, such as antihistamines, specifically block histamine receptors (H1 receptors) to prevent allergic reactions. They directly interfere with the action of histamines.
