Introduction

Figure 1:Structure of Nicardipine.

Lupinepublishers-openaccessjournals-Nanotechnology-nanomedicine

Nicardipine is chemically identified as 1, 4-Dihydro-2, 6-dimethyl-4-(3-nitrophenyl)-3, 5-pyridinedicarboxylic acid methyl 2-[methyl-(phenylmethyl) amino]ethyl ester (Figure 1). The molecular weight of NCD is 479.52 [1]. The melting point of NCD in the range of 136-138 °C (277-280 °F) [2].It is a calcium channel antagonist class of dihydropyridine. It is now used for the treatment of angina pectoris and similarly used in the managing of hypertension [3]. Most CCBs, including amlodipine, felodipine, isradipine, nicardipine, and nifedipine, belong to the dihydropyridine class [4]. The dihydropyridine have little direct effect on cardiac tissue at typical therapeutic levels; yet, they can evoke reflex tachycardia [5].

The schematic diagram shows the molecular mechanism of NCD (Figure 2). The CCBs indicated a number of important differences from the pharmacokinetic and pharmacodynamics point of views as well as for selectivity and duration of pharmacological action, while distribution the equal ability to interact with L-type voltagedependent transmembrane calcium channels [6,7].

Chemistry of NCD

It is a synthetic derivative of potent calcium channel blocker and nitrophenyl-pyridine [8]. The IUPAC name of nicardipine is 5-O-[2-[benzyl (methyl) amino] ethyl] 3-O-methyl 2, 6-dimethyl- 4-(3-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate [9]. The molecular formula is C26H29N3O6 and molecular weight is 479.533 g/mol [10]. NCD clinical properties and molecular mechanisms closely similar to those of nifedipine and the other dihydropyridine but nicardipine is extra selective for coronary and cerebral blood vessels. As compare to nifedipine the nicardipine have longer halflife [11].

Pharmacokinetic Properties

Almost 95% of nicardipine is bound by serum proteins, precisely α1-acid glycoproteins (AAG), albumin, and lipoproteins [4]. Nicardipine plasma elimination half-life has reached between 44 to 107 minutes in maximum studies with clearance of the drug due mostly to hepatic mechanisms [12]. The orally directed nicardipine is speedily absorbed and peak plasma concentrations arising between 20 minutes and 2 hours [13]. Distribution volume in normal volunteers have reached between 0.6L/kg to 63L. Lower than 0.03% of parent drug is enhanced from the urine of humans [14].

Pharmacodynamics Properties

Oral doses and intravenous of nicardipine may create rises in heart rate of up to 30% and 8 to 26% and dose-related reductions in mean arterial blood pressure correspondingly, and the duration of these effects which may be as long as 3 hours have generally been greater in patients at rest than in those at exercise [15,16]. While decreases in blood pressure have been efficiently preserved for some months without indication of tachyphylaxis, increases in heart rate occasionally seen after acute administration are not detected later extensive time oral treatment [15].

Nicardipine is related to further peripheral vasodilators (Figure 3) [17]. Nicardipine constrains the influx of extra cellular calcium crosswise the myocardial and vascular smooth muscle cell membranes maybe by deforming the channel [18]. The reduction in intracellular calcium constrains the contractile developments of the myocardial smooth muscle cells, affecting dilation of the coronary and systemic arteries, enhanced oxygen transfer to the myocardial tissue, diminished total peripheral resistance, reduced systemic blood pressure, and decreased afterload [19].

Analytical Method

The substantial literature survey exposed that, the development and validation of analytical methods for identification and quantification of drugs and other molecules of interest in Pharmaceutical Matrices [20,21]. Various analytical methods were developed viz HPLC, UV/Visible spectrophotometry, spectrofluorometric, LC-MS and voltammetry for estimation of NCD the dosage form [22]. The proposed method represents the determination of NCD in single and simultaneous method with Nifedipine, Isradipine, Aliskiren, Amlodipine, Verapamil HCl, Diltiazem HCl and Flunarizine [23].

Bioanalytical Method

Validated, Choosy and complex analytical systems for the quantifiable estimation of drugs and their metabolites (analytes) and biomarkers are serious for the effective manner of nonclinical and biopharmaceutics and clinical pharmacology studies [24,25]. Validating bioanalytical techniques contains carrying out all of the processes that establish that a specific method used for quantifiable measurement of analytes in a certain biological medium (e.g., blood, plasma, urine, or serum) is reproducible and dependable for the proposed use [26].

(Figure 4) The technique of high performance liquid chromatography (HPLC) was established in the late 1960s and early 1970s from knowledge of the theoretical principle that already had been recognized for the earlier chromatographic technique [27]. The method is created on the same modes of separation as classical column chromatographic, i.e. adsorption, partition (including reversed-phase partition), ion exchange and gel permeation, but it differs from column chromatography in that the mobile phase is pumped over the packed column underneath high pressure [28,29]. Estimation of NCD single or in combination with added drugs in pharmaceutical matrices and biological fluid by HPLC are note down in (Table 1 & 2) [30].
