Hi I had the question about the apocalypse where the vaccine causes schizophrenia. Would it make sense if the MC found a blue print of some sort that helped her make the meds she needed? Like a list of ingredients and then directions. Or would it make more sense to find someone who's kept a lab going through the apocalypse to help her, like a researcher or scientist.
Having your character find a still-functioning laboratory with a chemist would be a great idea! I think that’s the ideal solution. @scriptchemist should be able to get you further information about what you’d need!
A disclaimer before I start: my organic synthesis experiments were on a relatively small (i.e. not commercial) scale, and I’m assuming your MC and sidekick chemist would be doing the same. I have no experience with medicinal synthesis on a commercial scale.
If your MC wants to synthesize antipsychotics, having a fully-functioning lab and a Real Chemist™ would definitely be beneficial. Unfortunately, I don’t think they solve all the hurdles. Let’s go through them one by one.
1) Procedure
You can find papers detailing the synthesis of various antipsychotics online. As chemists devise new (and hopefully better) ways of performing various syntheses, including ones for antipsychotics, the procedures and results will eventually be published in various reputable journals. Some of them will be locked behind paywalls, but if your MC’s sidekick chemist is working at a fully-functioning (at least before the zombie apocalypse) lab, it’s plausible for the chemist’s employer to pay for access to papers. Even if whatever they get is not the absolute best procedure available in the world, it’s at least a decent starting point.
Your MC would definitely want a chemist’s assistance even with a written procedure, since papers are written for other scientists who know the subject. It’s generally assumed that other chemists know how to safely handle various chemicals and equipment; the average layperson would not know what precautions to take.
2) Equipment and common reagents
At a fully-equipped and fully-functioning lab, I expect your MC and their sidekick to have access to most of the equipment/reagents bench chemists use for organic synthesis.
There may be additional complications if the lab was damaged during the apocalypse, and of course sourcing additional reagents and equipment would be very difficult after the zombies attack.
Does the lab have enough resources in all their forms?
3) Precursors
This is the first major logistical hurdle. I put this in a separate category than 2) because generally precursors refers to a starting material that is pretty specific to the synthesis at hand. 2) will cover your common solvents, reducing/oxidizing agents, acids/bases, TLC stains, glassware, and general equipment that many people and many projects can use. A precursor is a starting material specific to this particular synthesis.
Chemistry is divided into various disciplines, and even those in the same discipline often focus their work/research on their own particular niche. There are a lot of chemicals out there, and if a chemist is spending their career working on the synthesis of an alkaloid from the cockroach plant, it’s very unlikely they’d have the appropriate precursors for clozapine just lying around. (Coworkers within the same company usually have the same general focus, so if the company isn’t making drugs it’s unlikely the right precursors would be available anywhere in the building. Even if they do make drugs, “drugs” is a very broad scope so they still may not have the right precursors.) Some precursors can be made, others can be bought or otherwise acquired, but all of that takes time. So your MC’s sidekick chemist is unlikely to have the correct precursors for the correct antipsychotic (does your MC know which one they need?) on hand unless their job happens to be synthesizing antipsychotics on the regular.
4) Experience
As I mentioned before, chemistry has a lot of sub-disciplines and their day-to-day lives can differ greatly. I have never made a superconductor in my life but it’s something J does regularly. That doesn’t mean a chemist from a different discipline can’t do a synthesis when needed–they understand the principles and lab practices–but you’d expect a bit of a learning curve, or for things to go not so smoothly at first. I’ve bombed the first attempt at a reaction and did fine on the second try using the same procedure. But unless your sidekick chemist is from the exact same niche and regularly makes the required antipsychotic (again, does your MC know which one?), the quality of their results would likely suffer, at least at first–in the midst of a zombie apocalypse, I imagine stress is high and sleep, food, and other life-sustaining necessities are low, which is an environment conducive to mistakes.
Let me be clear: inexperience is not an insurmountable hurdle. But it does take time to overcome, and your product yield and purity may suffer in the meanwhile. Does your MC have that kind of time in the middle of a zombie apocalypse, with presumably limited resources? And did I mention purity is really, really, really important for medicine? It’s hard enough to find the drug cocktail that works for you when said cocktail was prepared correctly; drugs and their dosages aren’t one size fits all. When you add questionable purity and improper storage into the equation, things get considerably more complicated.
5) Dosages
I mentioned this twice above, but it bears repeating: does your MC know which antipsychotic to make? Schizophrenia can be treated with more than one drug (unless medicine in your universe works very differently than medicine in our world, in which case this entire ask is probably moot). And even if your MC knows which drug, do they know how much to administer to the patient? (If, if, IF your chosen sidekick chemist is one who synthesizes antipsychotics on the regular maybe MAYBE they have some general idea of the drug required and a common dose, but chemists are not psychiatrists and their word shouldn’t be taken as gospel. Chemists do not, and should not, prescribe drugs.)
6) Excipients
Excipients are the non-active ingredients of a drug: the fillers, bulking agents, etc. But they also play important roles in medicine. A bulked up pill is easier to transport than 10 mg of drug, which may only be a few grains that’d flutter away at the slightest breeze. Excipients can facilitate drug absorption, increase stability/shelf life, enhance solubility, control the rate of drug release, etc. I have no idea what would happen if one takes a dose of antipsychotics without excipients to control the drug delivery, but I imagine it wouldn’t be good.
And if your MC and their sidekick chemist want to formulate the entire drug, excipients and all, that’s a whole other array of reagents and mixing and formulating for your characters to figure out. The excipients of choice vary by drug, by dose, and by various other factors. By the way, the published papers don’t usually have much information on excipients–that’s firmly in the territory of pharmaceutical manufacturing, whereas journal publications focus on the science of creation (in novel ways).
Some antipsychotics are administered as injections instead of pills; similar principles will apply when formulating the drug. Injections would also carry other considerations such as where to find needles, possibility of infection, etc.
7) Time
Preparation, reaction, working up, purifying, setting up the next reaction, formulating your final drug…all of that takes time. A lot of time. Some reactions take minutes or hours. Some take days. Some take months (not joking). And unless your MC has access to the perfect precursors that just happens to be lying around, this will take several reactions, and a lot lot lot of time.
Does your MC have that kind of time? Can they afford to make mistakes?
To summarize, here’s what your MC will need in order to pull this synthesis off:
- A clear understanding of which drug they’d need and the dose
- A functioning lab and a competent chemist (ideally one who makes drugs on the regular)
- Access to journals or other publications that detail methodology
- The appropriate precursors, reagents, and equipment
- Access to appropriate excipients and their formulations
- Time. A lot of time. A lot of time. Also some very stellar luck
- Incredibly stupid zombies (admittedly they’re usually not a bright bunch) because your lab will be a really obvious target if it’s up and running in the middle of an apocalypse
Points 3-6 may be simplified if the sidekick chemist makes drugs regularly.
To be honest, it’s a much more practical idea for your MC to raid a pharmacy or hospital (or several), because already-manufactured medicine has already passed the quality control checks for all the points I mention above. One could probably conduct a successful raid in 15-30 minutes if your MC is well-prepared. In a nice, non-apocalyptic environment 5-10 minutes is about the time I’d take to set up my reaction and get my notes all written down. It’s also very likely this synthetic procedure will be sequential–multiple reactions, each with its own time frame (several hours? A few days?), working up, purifying, analysis, characterize, set up following reaction…and in the meanwhile, the lab’s very existence is a giant target…
As a literature aside, in the novel The Time Traveler’s Wife the MC attempts to memorize the structure of risperidone in the future and then have a chemist synthesize it in the present, before the drug was actually developed. It goes about as well as you’d expect–which is to say, not well at all. Drug development, manufacture, and prescription are not arbitrary for very, very good reasons.
