>>12705472You'll notice that all alternatives to phenidate/amphetamine variants are all lower in efficacy, but have milder side effects. You'll see a similar pattern in both anti-depressants and anti-psychotics. Pharma has profited off these weaker modern drugs, even if they have piss poor efficacy, because a doctor will usually try to prescribe them first before getting to the "real stuff". So there's not as much demand for a stim with a marginally better profile. In time, perhaps.
>>12706944> There's not much point investing in slightly better new drugs for the same conditions unless there is some condition that requires your new $99/pill drug to be prescribed over regular old generic amphetamineYou don't understand the pharma market. New drugs are made all the time for conditions that already have readily available treatment, and they're often *worse*. Pharma companies are very decoupled from supply and demand, due to regulations and patents they can and do make money even when a cheaper and more effective solution already exists.
