Ngokubanzi, ukuphuhliswa kweemveliso ezintsha zebhayoloji kufuneka kudlule (1) uphando lwebhubhoratri (uphononongo lwendlela yenkqubo yemveliso kunye nokusekwa kwemigangatho yokulawula umgangatho) (2) Izifundo zangaphambili (i-pharmacological, toxicological, pharmacodynamic kunye nezinye iimvavanyo zezilwanyana) (3) Ukutya kwezempilo iya kuphumelela uvavanyo lokhuseleko lwemveliso evavanyiweyo. UPhando lwe-Pharmacodynamics), kunye nesigaba sesi-III solingo lwekliniki (uphando olukhulu lweClinical Pharmacodynamics Research), ngaphambi kokuba bavunywe kwimveliso yolingo. Emva konyaka omnye wemveliso yolingo, ichiza kufuneka lichaze iziphumo zozinzo lomgangatho kunye nolingo olwandisiweyo lwezonyango phambi kokufaka isicelo semvume yemveliso esesikweni.
