Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Hey Guys and Gals,

I'm here through slightly different channels. Researching 4-methylpyrazole/Fomepizole/Antizol for help with ALDH2 Deficiency. Basically means I can't drink anymore. As I'm sure some of you know, the ALD stands for Acetaldehyde, and is both what alcohol gets broken down into, and also an environmental contaminant that people are exposed to daily from loads of different sources.

Anyway, I felt I needed to point out and reiterate what Steph1234 already posted, that being that Convivia is already available in the form of Fomepizole, the main problem being that it's intravenous. So I have two questions for the community.

First, this a relatively simple compound structure as you can see by visiting Pubmed and searching for the compound Fomepizole.

Furthermore, there are about 50 vendors that supply it as can be seen on the same said search. Rather than waiting years for this to become available, or "flying to Tawain to score some" as one of the other members posted, we could just pool together for a buy-in. Or really even just buy it for yourselves, check it out;

I've checked a few different sources and here's an typical price through an online pharmacy for Antizol:
   
1mg/mL (4 x 1.5mL) 6.00 mL     ------$4,921.99-------


                  Wow, OK....


But I checked Sigma Aldrich through PubMed and here's the price for a Gram of the same stuff.

222569-1G   $77.30
   
That's both doable and a lot more of the same compound. This rapidly brings me to my second question:

While I don't really mind setting my own intravenous line (growing up with folks in the medical field/wife a nurse) are there any chemists or studying scientists out there that can look at this compound and figure out what the effective oral bio availability is?

Thanks, and hope this helps.

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Hey Aldous,

I took a look at both fomepizole and Alda-1 on SigmaAldrich and saw the hazard signs in both of their product descriptions. It seems like they will both cause acute organ damage if administered orally.

However, there is also a very recent 2015 scientific paper detailing the effects of Alda-1 on rat plasma.

"For the first time, the preclinical oral and intravenous pharmacokinetics of alda-1 were conducted. Alda-1 was found to be a rapidly absorbed, high clearance and poorly bioavailable compound in rats. Its plasma protein binding was found to be 82–86%." (Tenaja et al 2015; Bioavailability, plasma protein binding and metabolic stability studies of a ALDH2 activator, alda-1, using a validated LC-ESI-MS/MS method in rat plasma)

Despite the test results, Alda-1 seems to be a likely cure for the flush in the near future. I just wish that future was now. I wonder how efficient it is compared to fomepizole.

There also seems to be a 2014 patent from China that claims to have details pertaining to a DIY Alda-1 prep kit for oral administration. Search "Alda-1 oral self-microemulsion preparation and preparation method" or "Patent CN103976952 A." Hopefully, this will be made available internationally sometime soon.

From the patent: "According to the preparation disclosed by the invention, the solubility and the oral bioavailability of Alda-1 are remarkably improved by adopting a self-microemulsion nano technology, and the preparation method is simple and low in cost. Meanwhile, use of organic solvents such as DMSO (Dimethylsulfoxide) is avoided, so that Alda-1 is promoted to convert to clinical application and the safety of long-term application is enhanced."

BTW, what is your favorite Huxley novel? I've only read BNW.

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Sorry, Aldous, I should've researched fomepizole a little bit more.

Studies have found oral 4-MP to be as effective as the IV infusion. (Oral administration of fomepizole produces similar blood levels as identical intravenous dose; Marraffa et al 2008). I'm just not sure if the compound was prepared in some way to make it safer/more bioavailable.

According to Patent US20080021083 A1 (the supposed Raptor Pharma patent; use Google Patent to search),
"4-Methylpyrazole (4-MP, also known as fomepizole) is commercially available from chemical suppliers, including, for example, Sigma Aldrich (St. Louis, Mo.), and can also be synthesized easily in commercially viable quantities of pharmaceutical grade.

4-MP can be administered alone or in combination with other substances or active agents. In some embodiments, a composition comprising 4-MP and other ingredients, as described below, is administered.

4-MP can be administered according to any technique known to those of skill in the art. In certain embodiments, 4-MP can be delivered transdermally. In preferable embodiments, the subject can self-administer 4-MP to himself or herself. In preferable embodiments, 4-MP can be administered orally. When orally administered, 4-MP can be in a solid form, for example, as in a powder, tablet, capsule and the like, or in a liquid form."

The patent doesn't specify if the 4-MP has been cut with something else, but it doesn't seem like it is. It also recommends taking 1 mg/kg to 4 mg/kg about an hour before alcohol consumption. Since I weigh about 155 lbs or 70 kg, I would take about 140 mg 4-MP, assuming roughly 2 mg/kg.

I guess one can take a small scoop of 4-MP safely, unless this patent is completely wrong or hasn't been tested. I still wouldn't recommend trying it, but a doctor or scientist would definitely be able to give us some good advice on this.

Thanks for bringing this compound to light again. I would discourage buying the compound and trying it for yourself, unless a medical professional, such as your wife, gives you the OK, but I think our cure is waiting right around the corner.

Thanks, and good luck!!

That's what I've been hearing for last 7 years.  :-(

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Hey Aldous (again),

I just took another look at the "Oral administration of fomepizole produces similar blood levels as identical intravenous dose" article, and it seems like fomepizole is totally safe for normal, healthy humans to receive both orally and through IV. The article suggests that oral administration of the compound results in similar bioavailability to that of IV dosing, which is huge for potential users who don't have access to IV equipment or just don't like the whole invasive part of it.

Additionally, the World Health Organization also put out the "Application to Include Fomepizole on the WHO Model List of Essential Medicines." The WHO publication has references to tests on normal human test subjects (no ethanol poisoning, renal or hepatic failure) with only mild side effects of dizziness and nausea (probably not on the level on those with Asian glow anyway).

Sounds good to me.

:) Yeah, I probably shouldn't be so optimistic. Especially since I don't think drug developers or manufacturers are willing to push through with a drug just so that Asian folk can finally party it up, while finding cures for AIDS and cancer are still on the agenda. And it should be that way.

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Well, for all those waiting for Convivia, as AldousHuxley pointed out, it's pretty much readily available at the Sigma Aldrich website.

Regarding safety, from "4-Methylpyrazole: a controlled study of safety in healthy human subjects after single, ascending doses." (Jacobsen et al 1988)

Abstract

4-Methylpyrazole (4-MP), an inhibitor of alcohol dehydrogenase, is a possible future drug for the treatment of methanol and ethylene glycol intoxications and the severe ethanol-disulfiram reaction. Therefore a placebo-controlled, double-blind, single-dose, randomized, sequential, ascending-dose "Phase I study" was performed in healthy volunteers in order to determine the tolerance of 4-MP at dose levels of 10 (n = 4), 20 (n = 4), 50 (n = 4), and 100 mg/kg (n = 3). Along with each dose group, there were two placebos except with the 100 mg/kg group where there was only one placebo.

In the 10 and 20 mg/kg group there were no side-effects in any subject.

At the 50 mg/kg level, three out of four subjects experienced slight to moderate nausea and dizziness from 0 to 2.5 h after dosing. In the 100 mg/kg group all three subjects reported side-effects like nausea, dizziness, and vertigo, that were short-lived in two subjects, but lasted up to 30 h in one subject. The study was stopped after evaluation of the latter subject, so fewer subjects were completed in this last group. Despite these subjective side-effects, there were no significant changes in objective clinical parameters like pulse, blood pressure, body temperature, or blood and urine chemistries.

We conclude that at a single dose of 4-MP (10-20 mg/kg) producing plasma levels within a probable therapeutic range, no side-effects were attributed to 4-MP.

A gram of 4-MP goes for $77 on SigmaAldrich, which might be kinda pricey, especially if you are a heavier guy/gal, but it is very enticing.

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

I may take the risk of ingesting some of the chemicals and testing them to see if it works on myself. Has anyone had any expirience doing the same. I will be ingesting the chemical orally. Opinions?

I will be buying the chemical at the link below and giving myself a dose of probably 20mg.

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Hey CollegeBoy1,

Yeah, man, same here. I'll order some Fomepizole tomorrow from Cayman Chemical. It's only $35 for 500 mg, and $60 for a gram. I'll also be taking it orally. Definitely not IV'ing it, haha.

caymanchem(dot)com/app/template/Product.vm/catalog/17851

I would probably start off with a dose of 10 mg/kg then see if that works out well. If not, 20 mg/kg is the upper limit of the safe zone. If it plain doesn't work at that point, at least we tried. I'm also currently in college and heading into senior year, so this would be sweet if it worked. I wish you the best of luck, man. I know how it feels to try and hide myself at parties if people there don't know that I flush. It sucks.

I found a thread on the Drugs subreddit (lol) about a guy who uses Fomepizole in order to get drunk more efficiently.

reddit(dot)com/r/Drugs/comments/36ewke/why_isnt_fomepizole_more_popular/

Unfortunately, getting drunk on less alcohol is a side effect of the compound since the ethanol is not metabolized as quickly into acetaldehyde. I PM'd him and responded to his thread about his dosage, but no response yet. I will update this thread if I get a reply.

Fomepizole does have some dangerous side effects, such as vertigo and nausea, but only if taken in abnormally high doses, it seems. I would recommend getting a mini spoon set and small digital scale with some weighing papers from Amazon, which should only run you an additional 20 bucks on Amazon, just to make sure you get the dosages as exact as possible.

I have this small digital scale from Amazon, and it's only 7 bucks.

amazon(dot)com/gp/product/B002HEIE0U?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00

Again, good luck, and stay safe, man. I'll try and do the same!!

Looking forward to hearing about your experiment.

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Haha, thanks, Dalmore. That makes it a lot better. I guess you definitely can link here.

What's your take on this? Pushing it too far?

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

It will be good news if fomepizole works for you but I think it's still too expensive.  It would be great if one of those anti-hangover pill companies can buy fomepizole in bulk (usually costs less) and market it in pill form. 

Anyone here have a connection with one of those companies?

In the mean time, I'm posting my results on taking l-cysteine and vitamin C in combination with antacid pill on H2 Blockers (Tagamet, Pepcid, Zantac, Axid) forum here.

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Yeah, you're right, it is pricey. I read your results on the other thread, and that is awesome. Will definitely try that out next.

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Hey guys,

Major roadblock for purchasing fomepizole: most vendors won't ship to individuals with residential addresses.

Sigma Aldrich, Cayman, Abblis all require a university/company address. Oh, well. If anyone else who's been interested in this compound has a way to secure it, let us know!

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

You can give yourself a company name that's established today...  :-)

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Haha, yeah, the "I swear it's just for the Asian glow, not for cooking up drugs in my basement" Inc. Founded 2015.

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

It seems like something will never be available for us?? After 8 years searching myself, nothing has really changed at all. Highly dissapointing

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

battlingnelson, any luck with fomepizole?

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Uni Pharma may not be the only source for Convivia type of pill.  Here are couple others, one is in progress and the other may already be selling it to Europe, Asia and Middle East.

Re: Convivia by Bennu / Raptor Pharmaceuticals Corp.

Hey guys,

Starting to look for more sources of fomepizole in my free time. Still haven't found a way to have it sent to my dorm room. I'll let you know if I find anything.
