Discussion Overview

The discussion revolves around the body's immune response to medication, specifically whether the immune system can reduce the effectiveness of a drug over time, particularly in the context of developing tolerance to medications like benzodiazepines. The scope includes aspects of pharmacology, tolerance mechanisms, and personal experiences with medication.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant questions whether the immune system attacks medicine and if the body can reduce the percentage of a drug in the bloodstream over time despite continuous intake.
  • Another participant emphasizes the ambiguity of the term "medicine," suggesting that it could refer to various substances, including supplements and pharmaceuticals.
  • A participant discusses the concept of tolerance, explaining that it may involve downregulation of receptors rather than an immune response, particularly in the context of benzodiazepines.
  • Personal experiences are shared regarding the effectiveness of Ativan, noting fluctuations in its efficacy over a short period.
  • One participant advises seeking professional medical attention for alternative solutions, while another participant confirms that the medication is legally prescribed for a loved one.

Areas of Agreement / Disagreement

Participants express differing views on the role of the immune system in relation to medication, with some suggesting tolerance mechanisms rather than immune responses. There is no consensus on the initial question regarding the immune system's involvement.

Contextual Notes

Participants have not defined key terms like "medicine" or "tolerance" in a universally accepted manner, leading to potential misunderstandings. The discussion also reflects individual experiences that may not generalize to broader pharmacological principles.

Who May Find This Useful

Individuals interested in pharmacology, those experiencing medication tolerance, or anyone seeking to understand the interactions between the immune system and medications may find this discussion relevant.

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.
