Could Electronically Controlled Drugs Reduce Adverse Effects? (CNET)

Could electronically controlled drugs reduce side effects? | Cutting Edge - CNET News:



In the realm of oncology this could have especially dramatic ramifications.



Excerpt:


"Reporting in the journal ACS Nano, researchers led by Dr. Xinyan Tracy Cui at the University of Pittsburgh say their new approach allows them to electronically control the release of very specific amounts of drugs to certain parts of the body. To do this, they incorporated extremely thin nanosheets of graphene oxide that were loaded with the anti-inflammatory drug dexamethasone into a polymer scaffold that conducts electricity. By zapping the nanosheets with an electric current, they were able to release the drug -- using the thickness of the sheets to control how much drug was being carried, and the number and magnitude of zaps to control how much of the drug was released."

Pharmacy History

"The earliest known compilation of medicinal substances was ARIANA the Sushruta Samhita, an Indian Ayurvedic treatise attributed to Sushruta in the 6th century BC. However, the earliest text as preserved dates to the 3rd or 4th century AD.
Many Sumerian (late 6th millennium BC - early 2nd millennium BC) cuneiform clay tablets record prescriptions for medicine.[3]

Ancient Egyptian pharmacological knowledge was recorded in various papyri such as the Ebers Papyrus of 1550 BC, and the Edwin Smith Papyrus of the 16th century BC.

The earliest known Chinese manual on materia medica is the Shennong Bencao Jing (The Divine Farmer's Herb-Root Classic), dating back to the 1st century AD. It was compiled during the Han dynasty and was attributed to the mythical Shennong. Earlier literature included lists of prescriptions for specific ailments, exemplified by a manuscript "Recipes for 52 Ailments", found in the Mawangdui tomb, sealed in 168 BC. Further details on Chinese pharmacy can be found in the Pharmacy in China article."
