Paricalcitol Accordpharma injectable solution is administered through the dialysis access.
Adults
1)The initial dose should be calculated based on the baseline levels of the parathyroid hormone (PTH)
The initial dose of paricalcitol is based on the following formula:
Dose initial (micrograms) = | baseline level of intact PTH in pmol/l |
8 |
or
The maximum safe dose administered in clinical studies was 40 micrograms. 2)Dose adjustment Currently accepted levels for the PTH range in patients with terminal renal failure undergoing dialysis is not more than 1.5to 3 times the upper normal non-uremic limit, 15.9 to 31.8 pmol/l (150-300 pg/ml), for intact PTH. To achieve the desired levels of physiological variables, individualized dose adjustment and monitoring are necessary. If hypercalcemia or a corrected Ca x P product, elevated persistently, greater than 5.2 mmol2/l2(65 mg2/dl2), is observed, the dose should be reduced or discontinued until these parameters normalize.
The following table is suggested as an approximation for dose adjustment: | ||||
Guideline suggested dose (dose adjustment in intervals of 2 to 4 weeks) | |
PTHi level in relation to the baseline level | Adjustment of paricalcitol dose |
Equal to or greater than | Increase by 2 to 4 micrograms |
Decrease <30% | |
Decrease = 30% and = 60% | Maintain |
Decrease > 60% | Decrease by 2 to 4 micrograms |
PTHi <15.9 pmol/l (150 pg/mL) |
