Story 1:
A patient arrived at the doctor's office with an adhesive patch on his back. The doctor inquired, "What's that for?"
The patient replied, "My wife put it on me last night. She said it was the latest 'pain relief' patch."
The doctor chuckled, "I think your wife may have mistaken it for a nicotine patch. It'll help you quit smoking, not relieve pain."
Story 2:
A teenager overheard his parents talking about how amazing adhesive drug delivery was. Excited, he ran to his room and slapped a nicotine patch on his forehead.
His mother found him later, puzzled. "What are you doing?"
"I'm quitting smoking!" he exclaimed. "The patch is right over my brain, where all the addiction lives."
Story 3:
A group of researchers were experimenting with a new adhesive drug delivery system for pain relief. They applied the patch to a volunteer's shoulder and sent him home.
The next day, the volunteer called back. "Your patch didn't work at all!" he complained.
The researchers were perplexed. "But it should have released pain-relieving medication for 48 hours."
"Well, I went swimming in the ocean," the volunteer explained. "The waves must have washed it off."
Lesson Learned: Always consider patient instructions and the potential for environmental factors when designing adhesive drug delivery systems.
