The capability of Several Population-based Approach Software to Analyze Sparse Drug Plasma Concentration Data after Intra-Venous Bolus Injection Akhmad Kharis Nugroho; Lukman Hakim
Indonesian Journal of Pharmacy Vol 30 No 4, 2019
Publisher : Faculty of Pharmacy Universitas Gadjah Mada, Yogyakarta, Skip Utara, 55281, Indonesia

Monolix, NONMEM, and WinBUGS-PKBUGS are among available software package for population-based modeling. The sparse condition of drug plasma concentration versus time (Cp-time) data is prevalent in clinically based studies involving patients. It is not ethical in this case, to collect a many and large volumes of blood samples. This study was aimed to simulate the capability of Monolix, NONMEM, and WinBUGS-PKBUGS to analyze very sparse Cp-time data after an intravenous bolus drug administration and to estimate the minimum number of Cp-time data required for an adequate analysis. Data of Cp-time were obtained based on simulation using the pharmacokinetic one-compartment open model following an intravenous bolus administration of 50 mg of a hypothetical drug. In this respect, six random values of k (rate constant of elimination) and Vd (volume of distribution) with mean and standard deviation values of 0.3 ±0.1 per hour and 30 ± 10 L, respectively, were used to create simulated Cp-time data of 6 subjects. Simulated Cp-time data in each subject were randomly ranked to choose data based on the intended number of samples in each subject. Several sparse Cp-time data scenarios, starting from a very limited state, i.e., with a total of 6 Cp-time data (1 datum per subject) to a rich situation with 48 Cp data (8 data per subject), were examined.The goodness of fit evaluations, as well as the similarity of individual values of k and Vd to the respective real values (p>0.05), indicate that nonlinear-mixed-effect-model using Monolix, NONMEM and WinBUGS-PKBUGS can appropriately describe sparse Cp-time data even with only 2 data per subject. This fact is an important finding to support the demand of analytical tool for a limited number of Cp-time data such as obtained in therapeutic drug monitoring event.

Pendahuluan: Andrografolid merupakan senyawa yang sukar larut dalam air, penentuan jumlah dan profil pelepasan andrografolid dari bentuk sediaan perlu dilakukan. Tujuan: Penelitian ini dilakukan untuk menentukan jumlah dan profil andrografolid yang dilepaskan dari formula granul kombinasi ekstrak terpurifikasi herba pegagan dan herba sambiloto. Hal tersebut untuk memastikan eksipien tidak mengikat zat aktif. Metode: Uji pelepasan dilakukan dengan melakukan uji disolusi menggunakan media dapar asetat pH 4,5. Hasil disolusi granul kombinasi ekstrak terpurifikasi herba pegagan dan herba sambiloto ditentukan menggunakan KLT-densitometri. Hasil: Hasil perhitungan efisiensi disolusi (ED60) sebesar 75,00% ± 1,33. Profil disolusi ditentukan dengan regresi nonlinear dengan pendekatan orde nol, orde 1, Higuchi, Hixon Crowell dan Korsmeyer Peppas. Mekanisme penentuan profil disolusi dari pelepasanan andrografolid dilihat secara visual dari kesesuaian hasil prediksi solver (QPrediksi) dan hasil percobaan (Qobservasi) dengan melihat garis identitas. Kurva dari suatu model yang mendekati garis identitas merupakan gambaran mekanisme pelepasan andrografolid yang dibentuk dengan pendekatan tersebut. Kurva dengan pendekatan Korsmeyer Peppas terlihat lebih dekat dengan garis identitas bila dibandingkan dengan 4 model pendekatan yang lain. Berdasarkan perhitungan regresi nonlinear, pelepasan andrografolid dikontrol dengan mekanisme difusi matriks, yang berarti pelepasan andrografolid dari granul terjadi karena adanya pengikisan lapisan terluar karena Avicel PH 101 terhidrasi dengan cepat. Dengan menggunakan persamaan Korsmeyer-Peppas mekanisme pelepasan andrografolid mengikuti hukum difusi Fick dengan nilai n = 0,320 (< 0,45). Kesimpulan: Jumlah dan profil pelepasan andrografolid dari granul adalah hasil penelitian yang dapat dijadikan suatu referensi untuk menentukan jumlah ekstrak yang dipakai dalam formulasi.

Nanoparticle formulation is important for systemic drug delivery via several routes. This research was aimed to establish optimal formation of chitosan nanoparticle formulation with losartan, an antihypertension known as an angiotensin II receptor antagonist. Ionic gelation method was used. Formulation was established in 2 steps. Firstly, determination of the best losartan and chitosan concentrations which can produce physically stable nanoparticles without precipitation, at room temperature within 25 days. Secondly, optimization of the process by factorial design method of two factors, including pH (4.0 and 5.0) and the stirring rate (350 and 700 rpm), with the loading capacity of the nanoparticle as the observed response. The obtained nanoparticles were evaluated further for its particle size and zeta potential. The physichal stability tests indicated that two nanoparticle formulations containing losartan-chitosan of (14 mg% : 35 mg%), and losartan-chitosan of (21 mg% : 35 mg%) were stable. The factorial design studies suggested that pH 4 and the stirring rate of 350 rpm were the optimal conditions which produced the highest loading capacity (47,7%). The particle size and zeta potential of the stable nanoparticle were 290.3±52.6 nm and +50.8 ±4.8 mV respectively.

Ofloxacin is an antibiotic and categorized as class 2 in Biopharmaceutics Classification System (BCS). Ofloxacin solubility is dependent on pH of the solvent due to its amphoteric properties. The objectives of this research was to investigate the effects of pH and ionic strength on solubility profile of ofloxacin. Ofloxacin solubilities were measured at various pH ranged from 1.5 to 12.5 and ionic strengths from 0.01 to 0.20 respectively. Solubility experiments were carried out using shaking thermostatic-waterbath for 3 hours at a temperature of 37°C ± 1°C. Results showed that ofloxacin solubility increased at pH’s below the pKa1 value (6.08) and above the pKa2 value (8.25). However, the solubility decreased at pH’s between pKa1 and pKa2. Changing the solution pH from 6.2 to 1.5 or to 12.5 affected the solubility of ofloxacin increased about 9.96 and 8.64 times higher, respectively. Ofloxacin solubility in various ionic strengths showed that stronger ionic strength solution caused an increase in ofloxacin solubility. This mean that there was a salting in phenomena. Least-Square Fitting Analysis using Henderson-Hasselbalch equation for amphoteric compound was insufficient to describe ofloxacin solubility process in a series of pH.
