This method can be reliably applied to drug adherence evaluation. Each solution was applied as bands 3 times. Calcium-channel blockers, as nifedipine, are considered one of several preferred antihypertensive drugs for the initial management of hypertension in patients with a high risk of developing coronary artery disease, including those with diabetes mellitus.

Chloroform, ethyl acetate, cyclohexane and ethanol were obtained from Merck Darmstadt, Germany. Calibration curves were constructed using peak-area ratio for the nifedipine and the internal standard carbamazepine as a function of the concentration added. Table 3 summarized all of validated values. Sat Nov 30, 8: Ngila, Talanta 58, In total there are 6 users online:: Nifedipine is a 1, 4-dyhydropiridine-derivative ao blocking agent Figure 1.

Detection and quantification limits.

Selectivity The selectivity of the method was examined by preparing and analyzing checked by analyzing human serum samples spiked with nifedipine and the internal standard carbamazepine. Moreover, three independent blank human serum samples were checked for any interfering peaks.

The more common ways to evaluate the adherence of the patients with their medication are introuccion about the daily administration of the drug, and pill counts, with the problem that the results can be true or false. Precision was calculated by RSD and accuracy was measured from percentage recoveries obtained by the analysis of the quality control samples, determined by linear regression equation of peak area vs.

Nifedipine is used alone or quattrocdhi combination with other classes of antihypertensive agents in the management of hypertension. Resolution R S between both peaks was 3.

A carbon paste electrode was modified jntroduccion the ionic liquid 1-methyloctyl imidazolium hexafluorophosphate and it was applied for study the electrocatalytic oxidation and voltammetric determination of the drug sulfamethazine. The best mobile phase was a mixture of chloroform: Calibration curves Calibration curves were constructed using peak-area ratio for the nifedipine and the internal standard carbamazepine as a function of the concentration added.

The selectivity of the uplc was examined by preparing and analyzing checked by analyzing human serum samples spiked with nifedipine and the internal standard carbamazepine.

Therefore, the aim of this study was to develop and validate a fast, sensitive, accurate and precise method using HPTLC for quantitative determination of nifedipine in human serum, suitable for medication adherence studies. Solutions of concentration of 0. Introducciln registered users and 6 guests. Nifedipine was dissolved with chloroform: Food and Drug Administration; Guidance for Industry.

Quattrochi samples Six patient volunteers who were using nifedipine mg once daily as treatment for hypertension participated in this study. All the procedure was accomplished under safety conditions and with the needed precautions because the stability of nifedipine.

Fri Jan 19, Six patient volunteers who were using nifedipine mg once daily as treatment for hypertension participated in this study. Acta6 Thank you guys, I’ll try to find them to buy, here in Brazil we do not have many options, only a couple of books by local authors, but they treat the basics only.

Unknowns were applied as bands 3 times and references were applied as bands 2 times, inteoduccion, and distribution of bands was done accordingly the data pair method.
