Scopolamine and Sancuso are both prescription patches used to help prevent nausea and vomiting, but they contain different medicines and are used for different situations.
| Scopolamine patch | Sancuso patch | |
|---|---|---|
| Active ingredient | Scopolamine | Granisetron |
| Drug class | Anticholinergic | 5-HT3 serotonin receptor antagonist |
| Mainly used for | Motion sickness and postoperative nausea/vomiting | Nausea and vomiting caused by moderately or highly emetogenic chemotherapy |
| Where applied | Behind the ear | Upper outer arm |
| Typical duration | Delivers medication for up to 3 days | Designed to cover chemotherapy treatment lasting up to 5 consecutive days |
| Common side effects | Dry mouth, dizziness, drowsiness, blurred vision | Constipation, headache, skin irritation |
Scopolamine works by blocking acetylcholine signals involved in motion and balance, which is why it is particularly useful for motion sickness. In the U.S., the patch is also approved to prevent nausea and vomiting associated with surgery.
Sancuso is the brand name for granisetron transdermal system. It blocks serotonin 5-HT3 receptors involved in the vomiting reflex and is specifically approved for adults receiving chemotherapy that may cause nausea and vomiting. It is generally applied 24–48 hours before chemotherapy.
So, although both are anti-nausea patches, they are not interchangeable: scopolamine is mainly for motion sickness/surgery, while Sancuso is primarily for chemotherapy-related nausea and vomiting. patch mainly used to prevent nausea and vomiting caused by chemotherapy.
