🔵 Zyprexa (Olanzapine)

Serotonin (5-HT2A)

• Strong blocker
• Strong serotonin effect =
  ✔ heavy sedation
  ✔ big appetite increase
  ✔ strong mood stabilization

Dopamine (D2)

• Strong blocker
• Strong dopamine effect =
  ✔ powerful antipsychotic
  ✔ fast control of mania & hallucinations

➡️ Overall:
Zyprexa hits BOTH serotonin and dopamine strongly.
It is one of the most powerful atypical antipsychotics.

🟣 Seroquel (Quetiapine)

Serotonin (5-HT2A)

• Moderate blocker
• Helps with:
  ✔ calming
  ✔ mood stabilization
  ✔ depression (especially from its metabolite, norquetiapine)

Dopamine (D2)

• Weak blocker
• Means:
  ✔ milder antipsychotic strength
  ✔ gentler effect
  ✔ fewer movement side effects
  ✔ better for sleep and anxiety

➡️ Overall:
Seroquel hits serotonin moderately and dopamine lightly.
It is softer and less “heavy” than Zyprexa.

⭐ Very Simple Summary

Medication	Serotonin Effect	Dopamine Effect	Overall Strength
Zyprexa	Strong	Strong	Very strong
Seroquel	Moderate	Weak	Gentle–moderate

If you want, I can make:
✔ A visual chart
✔ A receptor-binding percentage chart
✔ A simple analogy (like “Zyprexa = hammer, Seroquel = pillow”)
✔ A comparison focusing on depression, mania, anxiety, or sleep

Just tell me!

⭐ 1. Strength

• Zyprexa = Stronger
• Seroquel = Milder

Zyprexa works faster and harder on symptoms.

---

⭐ 2. What They Treat Best

Seroquel:

• Anxiety
• Bipolar depression
• Sleep problems
• Mild–moderate psychosis

Zyprexa:

• Severe mania
• Strong hallucinations/delusions
• Aggression
• When fast control is needed

---

⭐ 3. Side Effects

Seroquel:

• Sleepy
• Some weight gain
• Dry mouth

Zyprexa:

• A lot of weight gain
• Very sleepy
• Higher risk of diabetes

---

⭐ 4. How They Work on the Brain

Zyprexa:

• Blocks dopamine + serotonin strongly
• More powerful effect

Seroquel:

• Blocks dopamine lightly
• Blocks serotonin moderately
• Feels smoother and gentler

---

⭐ 5. How They Feel

Seroquel:

• Calming
• Good for sleep
• Easier to function on

Zyprexa:

• Heavy, strong
• Very sedating
• Fast symptom relief

---

✅ Very Short Summary

• Need strong, fast antipsychotic treatment? → Zyprexa
• Need calming, sleep, depression help, fewer metabolic issues? → Seroquel
