The study covered influence of Isradipine (2.5 mg administered twice daily 
during 6 weeks) on blood circulation in the heart and occupationally important 
functions and traits among 30 drivers having mild and moderate arterial 
hypertension (AH). Systolic and diastolic pressure demonstrate reliable decrease 
in all the examinees with mild AH and in 93.8% of the examinees with moderate 
AH. Isradipine proved to influence positively decrease of hypertensive reactions 
and subclinical myocardial ischemia. Isradipine presented statistically 
significant improvement of the studied psychophysiologic parameters (quickness 
of latent and motor visual reaction, number of errors in color choice, exactness 
in following the mobile object). Thus, all above enables to recommend Isradipine 
(Lomir) as effective and safe method correcting arterial hypertension in 
drivers.
