AI Thread Summary
The discussion centers on the effects of long-term medication use, specifically regarding the development of tolerance to drugs like Ativan (lorazepam). It highlights that the body can build tolerance, leading to decreased efficacy of the medication over time, primarily due to changes in receptor sensitivity and neurotransmitter systems, rather than the immune system attacking the drug. The conversation emphasizes the importance of consulting a healthcare professional for alternative solutions if the medication is no longer effective. The user shares a personal experience with Ativan, noting initial effectiveness followed by diminishing results, and acknowledges a significant improvement in anxiety despite the issues with the medication's efficacy.

Slightly different question, if we start taking a small constant daily dosage of medicine that quickly reaches some roughly constant percentage in the blood-stream does the body have mechanisms that over a period of days can reduce the percentage of that medicine in the blood-stream even if we continue taking the medicine at a constant daily rate? I was wondering if the immune system attacks medicine?

Thanks for any help!

For starters define "medicine". That is a highly ambiguous term that could mean anything from iron supplements to proteins to live cultures.

Was thinking in particular of the drug Ativan,

What happens is that you build a "tolerance" to the medication whereby it's efficacy decreases over steady (tonic) use. What is tolerance? Well, for psychoactive drugs it's typically downregulation of the relevant receptor(s). I don't think the problem is the immune system attacking the chemical.

From: https://en.wikipedia.org/wiki/Benzodiazepine_dependence

"Tolerance develops rapidly to the sleep-inducing effects of benzodiazepine. The anticonvulsant and muscle-relaxant effects last for a few weeks before tolerance develops in most individuals. Tolerance results in a desensitization of GABA receptors and an increased sensitization of the excitatory neurotransmitter system, glutamate such as NMDAglutamate receptors. These changes occur as a result of the body trying to overcome the drug's effects. Other changes that occur are the reduction of the number of GABA receptors (downregulation) as well as possibly long-term changes in gene transcription coding of brain cells."

My guess is that you got your hands on some benzodiazepines (e.g., Ativan) somehow whether from a friend or legitimate prescription and they're starting to not work as well as they did a couple weeks ago. It's not likely to get any better. So my advice to you (in the spirit of Evo) is to seek professional medical attention for perhaps an alternative solution.

If that doesn't work, I may have a buddy that can help you out :wink: (just kidding).
 
It is all legally prescribed for a loved one. It was the first drug in 7 weeks that had any effect to reduce some serious anxiety. Started to work this past Friday, worked great Saturday, not as much Sunday, Monday Tuesday. none of this was explained.

Bottom line is she is still in a much better place then last Friday morning, Hell.

Thank you for the help!
 
Tell your friend to talk to her doctor about it, we can't advise her here.

Thread 'Did they discover another descendant of homo erectus?'
The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
Whenever these opiods are mentioned they usually mention that e.g. fentanyl is "50 times stronger than heroin" and "100 times stronger than morphine". Now it's nitazene which the public is told is everything from "much stronger than heroin" and "200 times stronger than fentany"! Do these numbers make sense at all? How do they arrive at them? Kill thousands of mice? En passant: nitazene have already been found in both Oxycontin pills and in street "heroin" here, so Naloxone is more...
