Schematic presentation of the EIIP/AQVN criterion for selection of candidate antimuscarinic drugs with potential therapeutic effect on VVS. Active domain (red): AQVN (2.25–2.65), EIIP (0.074–0.096). Chemical space (blue) AQVN (2.40–3.30) EIIP (0.000–0.116) EIIP/AQVN domain of homologous distribution of >90% compounds from PubChem Compound Database. Statistics: inside the active domain: 21 (78%), outside the active domain: 6 (22%). Asterisk (*)-position of atropine and propentheline bromide, known anti VVS drugs, within AQVN/EIIP active domain.
