Lub tuam txhab tsuas yog ua haujlwm hauv cov ntaub ntawv raw rau poj niam yuag poob thiab txiv neej cov tshuaj noj.
Kev nqus sai sai tom qab kev tswj hwm qhov ncauj, ncav cuag qhov siab tshaj plaws ntawm cov ntshav plasma concentration (Cmax) ntawm lub sijhawm nruab nrab ntawm 2 teev tom qab noj. Qhov tseeb bioavailability tom qab kev tswj qhov ncauj ntawm cov tshuaj no tsis tau txiav txim siab. Tus nqi thiab qhov nqus ntawm tadalafil tsis cuam tshuam los ntawm cov khoom noj, yog li cov khoom no tuaj yeem noj nrog lossis tsis muaj zaub mov. Lub sij hawm ntawm kev tswj hwm (sab sawv ntxov lossis yav tsaus ntuj) tsis muaj qhov cuam tshuam tseem ceeb ntawm tus nqi thiab qhov nqus ntawm qhov nqus, nrog qhov nruab nrab ntawm kev faib tawm ntawm kwv yees li 63 litres, qhia tias tadalafil faib rau hauv cov ntaub so ntswg. Ntawm kev kho mob ntau, 94% ntawm tadalafil hauv plasma yog protein- khi. Protein khi tsis cuam tshuam los ntawm lub raum tsis ua haujlwm. Hauv cov ntsiab lus noj qab haus huv, qhov nruab nrab qhov ncauj tshem tawm ntawm tadalafil yog 2.5 L / teev, thiab qhov nruab nrab ib nrab - lub neej yog 17.5 teev. Tadalafil feem ntau raug tso tawm raws li cov tshuaj tsis ua haujlwm, feem ntau ntawm cov quav (kwv yees li 61% ntawm cov koob tshuaj), thiab tsawg dua ntawm cov zis (kwv yees li 36% ntawm cov koob tshuaj).
