Modafinil is a medication that treats too much tiredness due to selected snooze situations like narcolepsy, slumber apnea and shift get the job done sleep condition. The brand identify of this medication is Provigil®.

These considerable improvements within the autonomic procedure warrant cautious thing to consider when prescribing modafinil to those with pre-current cardiovascular conditions.[94] The rise in heart fee and hypertension can worsen the signs and symptoms of this sort of pre-current conditions as hypertension, arrhythmia, and cor pulmonale.

Whilst we demonstrated that PCR was not improperly assigning DA to some non-DA principal ingredient in electrically evoked DA signals, the DA concentrations analyzed had been Considerably larger as opposed to nonsignificant modifications detected in basal DA and recent estimates of basal DA of ≈one hundred nM (Atcherley et al., 2015). On the other hand, PCR has Beforehand detected both equally boosts and decreases in DA amounts within these nonsignificant concentration improvements and nicely underneath one hundred nM (≈five–40 nM) (Hart et al., 2014; Roitman et al., 2008). So, Even though PCR seems to have the requisite sensitivity to detect a modify in basal DA, a definitive determination of irrespective of whether MOD functions on basal DA involves additional analyze.

In animal scientific tests, the median lethal dose (LD50) of modafinil may differ amongst species and is dependent upon the route of administration. In mice and rats, the LD50 is around 1250 mg/kg if administered via an injection, although the oral LD50 for rats is 3400 mg/kg.
