I didn't even read the rest of this thread, but scrolling up I just saw that you went on to give unqualified medical advice:
Again, source -- "Trust me bro"
That's really not unqualified medical advice; its me stating what I know about the combination based upon available resources found on the web such as PubMed and Google Scholar. I stated, and I will repeat, that a Z-Pack is a little bit overkill in the case of pharyngitis. That is true; I don't see a reason to treat this with azythromycin when other alternatives exist that don't run any risk whatsoever and would be equally as effective.
Thanks for clarifying that the relative risk with azythromycin, but obviously I had to do my own research which turned up similar enough findings:
Although erythromycin frequently induces long QT interval and torsade de pointes, the newer drug, azithromycin, has rarely been reported to be associated with torsade de pointes. We report here the occurrence of a significant typical QT prolongation within a few hours after taking azithromycin...

An emerging body of evidence suggests that azithromycin therapy may prolong the QT interval and, in rare cases, precipitate the potentially fatal arrhythmia torsade de pointes. Patients with additional risk factors for QT prolongation appear to be at highest risk, including women, elderly...

methadone has only micromolar affinity as a hERG inhibitor so only large doses produce clinically significant hERG inhibition in healthy adults.
That is not at all what I have come to find via the web, so I would love to know where you found this information yourself as it seems sus...
I did find this though, "The main cardiac effects of racemic Methadone, a synthetic opioid, include prolongation of QT interval and torsade de pointes. The FDA approved racemic Methadone as an analgesic in 1947. In humans, Methadone is strongly metabolized in the body, predominantly in the liver by CYP3A4 and CYP2B6. CYP2B6 metabolized in vitro (
S)-Methadone with 1.8-fold preference
versus (
R)-Methadone. In a patch-clamp experiment, using HEK293 cells expressing hERG, (
S)-Methadone blocks hERG 3.5-fold more potently than (
R)-Methadone. Methadone is not a high-affinity blocker of hERG1, and the 3.5-fold difference between enantiomers might not be clinically relevant. The difference in hERG inhibition is accompanied by additional stereoselective PK and PD properties inducing the (
S)-Methadone toxicity.
Early studies pointed out disadvantageous side-effects of racemic methadone when compared to the (
R)-form, but they did not receive the deserved attention [83]. It is obvious that the use of pure (
R)-Methadone in place of racemic should be considered for all patients treated, for instance for pain, in order to reduce the risk of cardiac toxic effects and sudden death."
So, maybe you got confused when the article stated "Methadone is not a high-affinity blocker of hERG1, and the 3.5-fold difference between enantiomers might not be clinically relevant."???
Fuck if I know man... All I know is your response was quite shit and I have no respect for a dipshit that runs their mouth and retaliates with bad information when trying to defend his position. I will give you some credit for your having been correct about azythromycin.
But, as
@LucidSDreamr and I were discussing, opiates such as heroin (as in this example) are not nearly as cardiotoxic as methadone:
"Both methadone and heroin inhibit hERG currents in a concentration-dependent manner. The following values were calculated for IC50 (concentration causing half-maximal inhibition) and n (the Hill coefficient): 4.8 μM and 0.9 for methadone, 427 μM and 0.7 for heroin. In conclusion, the potency for block of hERG currents is about 100-fold lower for heroin when compared to methadone."
Torsades de pointes (TdP) is a life-threatening form of ventricular arrhythmia that occurs under conditions of delayed cardiac repolarization indicated by prolonged QT intervals in ECG recordings. The main mechanism of QT prolongation and TdP is block of the rapid component of the cardiac...

I'm honestly too tired for this dumb shit... You sit here and say how the fact that methadone is known to be dangerous cardiovascularly speaking in its own right doesn't raise immediate alarm when combining with azythromycin which the article you referenced even acknowledged is a misconception which I politely asked you to enlighten me on. Meanwhile, in another thread he says psychedelics can't help people get clean because junkies are known to shoot dope at the peak of acid trips. Like, fuck.... yes, of course, but you're a lot more likely to recover if you actually try... Fucking critics everywhere on this forum... I'm more and more rapidly coming to find this is not a harm reduction forum so much as a mingling ground for drug addicts that don't give a fuck about their own lives.
