Conditional Statements in Python for Pharmacy Students (Clinical Decisions, Dose Adjustment & Toxicity Check)

Conditional statements in Python allow decision-making based on specific conditions. In pharmaceutical sciences, they are widely used for clinical decision support, dose adjustments, and toxicity monitoring.

🔷 What are Conditional Statements?

Conditional statements execute code based on whether a condition is True or False.

if condition:
    statement

🔷 if Statement

Executes code only if condition is true.

temperature = 102

if temperature > 100:
    print("Fever detected")

🔷 if-else Statement

Executes one block if true, another if false.

age = 30

if age > 60:
    print("Reduce dose")
else:
    print("Normal dose")

🔷 if-elif-else Statement

Used when multiple conditions exist.

temperature = 101

if temperature > 103:
    print("High fever")
elif temperature > 100:
    print("Mild fever")
else:
    print("Normal")

💊 Dose Adjustment Example

age = 65

if age > 60:
    print("Reduce dose")
else:
    print("Standard dose")

💊 Toxicity Check Example

concentration = 15

if concentration > 10:
    print("Toxic level")
else:
    print("Safe level")

💊 Combined Clinical Condition

age = 70
kidney_issue = True

if age > 60 and kidney_issue:
    print("Reduce dose significantly")

🧠 Memory Trick

• if → Decision
• elif → Multiple options
• else → Default action

🧪 Practice Exercise

Create a program that:

• Takes patient temperature
• Displays fever condition

❓ FAQs

Why are conditional statements important in pharmacy?

They help in clinical decision-making such as dose adjustment and toxicity monitoring.

What is the difference between if and elif?

if checks the first condition, while elif checks additional conditions.
