[edit] MECHANISM OF ACTION

Olopatadine is a potent selective antiallergic/antihistaminic agent that exerts its effects through multiple distinct mechanisms of action:

  • It antagonises histamine (the primary mediator of allergic response in humans) and prevents histamine induced inflammatory cytokine production by human conjunctival epithelial cells.
  • Olopatadine also acts as an inhibitor of the release of pro-inflammatory mediators from the mast cell

[edit] DOSAGE

The dose is one drop in the conjunctival sac of the affected eye(s) twice daily (8 hourly). Treatment may be maintained for up to four months, if considered necessary.
