AI Thread Summary
Controlled drug release technologies include various methods such as transdermal patches, liposomes, and other delivery systems designed to regulate the timing and rate of drug release. Key techniques for controlling drug release involve the use of polymers that respond to environmental stimuli, such as pH, temperature, or specific biological triggers. Additionally, osmotic pumps and biodegradable microspheres are established methods that allow for sustained release over time. The discussion emphasizes the importance of focusing on commercially available technologies rather than experimental approaches, highlighting the need for practical applications in drug delivery systems.

Hello

I read several articles about controlled drug release from patches, liposomes, etc

Can you tell me please which methods are available to control the release of a drug and what can trigger this release?

I am interested in developed available technologies rather that something experimental described in a single article.

Thanks!

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
