Part Descriptions
LP14726-1 Normeperidine
Normeperidine is a major metabolite of meperidine and very weak analgesic. It is half as potent as meperidine as an analgesic but 2-3 times more potent as a convulsant. The half-life of normeperidine is increased in patient's with renal failure. Symptoms of normeperidine accumulation progress from irritability to tremors and generalized seizures. Such patients are known to have high plasma concentrations of normeperidine. When naloxone is administered for normeperidine-induced seizures, an exacerbation of the seizures occurs due to antagonism of the seizure-suppressing effects of meperidine.

LP32035-5 Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
