Embodiment 6: pediatric paracetamol artifical low-bezoar and chlorphenzmine maleategel preparation and granule dissolution and bioavailability comparative test
Bioavailability compares:
(25~35 years old age, body weight 52~61kg) are divided into two groups to 12 healthy male volunteers (liver, renal function and electrocardiogram are normal) at random, 6 every group.All medicines of stopping using before the test abstain from smoking and drinking during being tried, and the volunteer is intersected respectively and taken Jiao Rang and gel, take medicine 1 week at interval for twice.Method: behind every group of experimenter's fasting 12h, one of intersection single oral Jiao Rang, or the gel of equal drug dose, the 100ml warm water delivery service, the back 2h that takes medicine advances the nutritious food of unified recipe, twice test unanimity, in the back 0.25,0.5,1 of taking medicine, 1.5,2,3,5,7,10h extracts ulnar vein blood 2ml, centrifugal 10min gets serum and places-20 ℃ of cryopreservation to measuring its blood drug level.
The pharmacokinetic parameters of two kinds of system types of result is similar, and difference does not have significance statistically.The bioavailability that gel is equivalent to Jiao Rang is 103.1%.
The comparison of dissolution:
By " Chinese pharmacopoeia version dissolution determination in 2000 item is regulation down, carries out the dissolution comparative test, and the result is from accumulating the stripping percentage rate as can be seen, and the dissolution and the capsule of gel are suitable.
