Drugs Definition and 66 Threads

Hi guys I am doing a graphic design project and I would need to know how this tests to check if your drink is been spiked works. Whats the chemical that react to the most common drugs used? thank you so much!

A friend of mine is telling me that the FDA (and presumably the EMA in europe) never approves any drug unless a drug company can patent it. This means that the effectiveness of things like Flavonoids, Melatonin, or even special uses of Vitamins, will never be approved by them no matter how...

There have been a number of approaches taken in developing drugs to combat the SARS-CoV-2 virus: 1. Interfering with the viral RdRP polymerase so the virus cannot replicate its RNA (Remdesivir, EIDD-2801, Galidesivir) (see: this thread) 2. Preventing the virus from attaching to the ACE2...

Hi. I'm planning research on Diabetes(T2DM) and for that, I'm looking for the top 4 antidiabetic medicines. [Moderator Note -- OP has edited their post and thread title to clarify which type of diabetes the question applies to] I've thoroughly googled but couldn't find any authentic article...

In this Vox video, the pharmaceutical industry is investigated in how they package and distribute medical drugs. Eyedrops are too big for the eyes resulting in using too much. Other drugs are distributed in single use containers where 50% of the drug is thrown away but someone still pays for...

Am I imagining it? Is there something in common about the structure of substances that interact with human biology which means they tend to be white? Do medication manufacturers just somehow artificially whiten them to meet consumer expectations? Thanks for any input.

How do clinicians determine the appropriate drug dose based on pharmacokinetic data? I was reading up on a Phase 1 clinical trial study for a chemo drug and was wondering how do clinicians and doctors come up with the drug dose based on these studies. Do they make use of the pharmacokinetic data...

Before anything, I'd just like to say I do not use nor promote the use of any drugs. I've experimented with cannabis a couple of years ago but quickly stopped when my senior years approached. I am now doing very well in my last years of school, especially in sciences. I am however struggling...

I'm not sure if this isn't the correct forum; but I recently was experimenting with dextromethorphan; and while on the drug, I had a psychotic break. All of a sudden I have retained positive memories from childhood, lost all depression, have incredible amount of excessive energy, and have the...

What really happens when the bacteria get exposed to a bacteriostatic drug? Bactericidal drugs cause cellular destruction but the static drugs, as per description are said to prevent the bacteria from replicating. But apart from this what happens to the bacteria, is it able to exist and function...

Previously, I am taking Double Major: Chemistry and Chemical Engineering. I have 60 units before but removed the engineering course so now i have 20 units left. This is because of financial reasons and personally I think in my college, most of the professors in chem engineering department...

Should an injury from overuse, such as a tendonitis, be treated with anti-inflammatory drugs, such as Ibuprofen, or do they retard the healing process and would it be better to just let the injury heal naturally? I found some papers supporting they harm the recovering process of the injury...

In the city I live it was just reported that in 2014 there were more heroin overdoses than traffic deaths. I have a family member addicted to heroin and it's a nightmare for the family. The US needs a radical change. Portugal could be the case study to look at. In 2001 Portugal decriminalized...

If you tell your doctor that you smoke weed or other drugs, will he tell the police? What charges can you face? I tried to do some research, but I could not find a reliable source. If you are a specialist on this subject, please state so and indicate where you live.

How do medical professionals, scientists or whoever studies this stuff figure out the lethal dose of a particular drug? It's not like they can perform experiments on humans. Do they just test them on animals and then extrapolate that to humans? Do they find some kind of pattern from people...

'Worst drugs' -- trying to find a page I remember reading a web page (maybe several pages on wikipedia) that talked about horrible drugs that were used only in extreme circumstances. These drugs had horrible side effects and perhaps low efficacy. They were rarely used. I remember an...

Why do acidic drugs remain unionized in acidic environement, and become ionized in basic environment? Similarly, why do basic drugs become ionized in acidic environment and remain unionized in basic environment?

Hey guys, I'm sure the thread title sparked an interest in some of you and may seem bizarre to others. I began to smoke marijuana at the age of 17 (I'm 19 now), and I must say that I do enjoy smoking and the camaraderie that accompanies it. Now I've never done any other drugs but the use of...

I read about long term use of these kinda antidepressants causing hippocampal neurogenesis and stuff like that but I'm focusing more on what long term use does to the various monoamine neurotransmitter pathways. I'll start with SSRIs because they are the simplest. Their main mechanism of action...

What kind of advances have been made in this field (since I don't stay on top of it)? If I wanted to image, say, where my fluorinated drug is going within a rat, is it possible? NMR is inherently not a sensitive modality. Hydrogen is vastly more abundant in a living organism than fluorine...

Alerted to this from a friend who is an alumni of Case Very excited to read the article in Science, when it comes out--Granted this is of course a press-release and prone to a certain kind of hype. That said still looks promising, I'm not aware of any potential treatments yet that have had...

My last colonoscopy I had demerol and versed, no pain during or after, PLUS I felt the best I've ever felt for the rest of the day (thank you Demerol). But my new doctor prefers propofol. It puts you to sleep, unlike the demerol/versed, where you are conscious, but feel no pain. You are...

This thread has https://www.physicsforums.com/showpost.php?p=3591985&postcount=5" that must be complied with. All posters must familiarise themselves before posting. Ryan_m_b Browsing this forum I haven't found a single discussion about psychedelic drugs... Which I consider a sad fact because...

I think many people would expect that a physicist is more inclined than the average guy in the street to be able to see through the propaganda/fear-mongering of the government & mainstream media. Also it's reasonable to think that someone well versed in physics is going to have an curious mind...

Some people use drugs combined in lipstick as a defense weapon in the streets. One of the drugs used is chloral hydrate. Does anyone else know what the other drugs are that are used in the lipstick for defense ? They may be some of the sedative-hypnotic nonbarbituates but I am not sure...

Hey PF, just thought I'd post a story. Kind of long, sorry. I'm 19 next week, and a freshman at a community college. Long story short, up until this semester my school effort has been hit and miss. I'd do great sometimes, then terrible at others. Until senior year, I just stopped caring...

First off I am nothing of a scientist or chemist. can you add a oxygen molecule to say marijuana without screwing it up? or if i add one of the inert gases to it? haha, I'm just thinking out loud what you scientists say?

As the title indicates, this post is directed towards the subject of Drugs and Toxins that affect the nervous system. I'll be writing a report on this and it is up to me to pick a specific drug or toxin to write about. I was just wondering what you all have to say about the subject. Maybe there...

One of my college professors was talking about brain-boosting drugs and their use in the science world. He seemed to support the idea with a belief that no one in the scientific world will criticize you for making a breakthrough if you used drugs to boost your performance. Unlike the sports...

Let x mg be the amount of drug in the patient at time t. Drug is injected into the patient at a rate of P mg per min The kidneys of the patient remove the drug at a rate proportional to the amount of drug at time t. At a particular point in time, the drug concentration in the patient...

I was wondering what people here think about the effects LSD, Marijuana and MDMA have on the brain. In its ability to learn, develop and problem solve after the drugs have completely worn off. Especially in learning physics and mathematics.

Dear twofish-quant, I found this thread interesting especially since I have a daughter in college, and have friend's whose kids are in the same situation. During a discussion with one of them about achievement, grades, stress, time management, cramming, all nighters, etc... I asked him...

For those who haven't come across this: http://news.bbc.co.uk/1/hi/uk/8334774.stm My facebook status sums up my feelings on the subject: Predictably, the shadow home secretary wallowed in the typical Tory self-image of the last bastion of law and order in a broken society, but the Lib...

Right, I'm putting this here first to get some general opinions and if it eventually gets moved to a biology/medical section, that would be good. Basically there has been a lot of debate between my housemates about whether or not cannabis and marijuana are better for you to consume than...

Hi, I am supposed to design 2 experiments for my senior year Chem class. Right now I cannot think of anything that is interesting, relatively advanced but at the same time at a high school level (its only a design lab so I can include advanced equipments). Topics that interest me the...

Fascinating. I love Canadian nature films.

has anyone from the US or England tried Modaphinil or similar to improve intelligence ?? does it really works or is just another Hoax. this topic was treated in the tv show "The Simpsons" when Bart takes Focusin ( a parody on ritalin ) and becomes a genius but extremely maniatic

Ok, a couple of mildly bad words, just cover your ears. :smile:

First of all, I know the rules about discussions of drugs, but I am not talking about illegal drugs here. I've read some articles about intelligence enhancing drugs, and it got me thinking. I had very strong opinions on either side of this case, and that surprised me. Let's say that the...

Hi yall, just had a question that got me thinking. Say you do a drug that builds tolerance, eg alcohol or opiates. If you took an extreme amount chronically is there any way to become completely immune to it to the point no amount of the drug will affect you at all?

I am thinking mostly about STDs for this matter. Is is possbile for a non-infected person to regularly take anti-viral drugs to prevent contracting HPV or HSV, even HIV?

I'm in IB Chemistry HL and I have a test on drugs and medicine tomorrow. Is there any website where I can study this from? The notes that the teacher gave us are kind of incomplete...

This came to me when I was doing some routine work yesterday; I work in the QC lab for a drug company which makes drugs for HIV and hepatitis. The lab is under GMP which means everything is tested multiple times and the amount of paperwork involved is staggering. When a bulk truck of acetone...

"Smart" drugs. Hello, i recently heard about "smart" drugs that could improve your brain activity or similar, for US forumers this will be more known i have heard about "tetra tab" and "Modaphinil" (or something similar, sorry I'm not a chemist) , of course they didn't make you a genious but...
