Gaster 10 Powder quickly controls excessive stomach acid that causes:

• Stomach pain

• Heaviness or bloating

• Acid reflux

• Heartburn

Stomach acid is produced when histamine binds to H2 receptors in the stomach lining.
Gaster 10 works by blocking these H2 receptors, preventing excessive acid secretion and relieving discomfort.

This powder form dissolves quickly in the mouth, making it convenient and fast-acting.

How It Works

• Histamine stimulates stomach acid production via H2 receptors

• Gaster 10 blocks these receptors

• Reduces excessive acid release

• Helps improve stomach discomfort

The acid necessary for digestion is controlled by other receptors, so this medicine can be taken regardless of meal timing.
