Roekmono, Harsono Hadi, Hilya Nur Imtihani, Luthviyah Choirotul Muhimmah, Rio Akbar Yuwono, Ruri Agung Wahyuono
Abstract
This work aims at investigating the reliability of ZnO-paper based microfluidic analytical devices (ZnO-µPAD) for blood plasma separation as well as bio-sensing of glucose and cholesterol. Two-layer paper-based microfluidic analytical devices coated with ZnO nanoflowers/ZnO spherical aggregates (ZnO-µPAD) for a rapid blood plasma separation and glucose sensing were developed. Plasma separation in ZnO-µPAD was evaluated experimentally and numerically using computational fluid dynamics package for a flow over porous networks. Glucose and cholesterol detection was carried out using spectroscopic techniques, both Fourier-transform infrared (FTIR) and Raman measurements. The plasma separation process on ZnO NF-μPAD requires 250 s. The spectroscopic investigation reveals that the IR absorptions and Raman signals at the typical vibrational frequencies of glucose and cholesterol are increasing at higher concentration. After subtraction from absorption background arising from ZnO and the paper, a specific and linearly increasing IR absorption (913 and 1349 cm
-1) and Raman signals (1346 and 1461 cm
-1) are observable with a relatively good sensitivity.

Abstract
The aim of this study was to develop a dose flexible paper dosage containing donepezil hydrochloride, with fast disintegration time and suitable mechanical strength, for the treatment of Alzheimer’s disease. Hydroxypropylmethylcellulose and pectin served as the hydrophilic polymeric bases of the ODF. The uniformity, in vitro disintegration time, drug release and the folding endurance of the ODF were examined. The in vitro results showed that 90% of donepezil hydrochloride was released within 20 minutes with mean disintegration time of 32 seconds. The result of the film flexibility test showed that the number of folding time to crack the film was average 200 times, an indication of sufficient mechanical property for patient use. All the required evaluations were recorded. ODF containing 30 mg of sucralose were more superior to saccharin and aspartame in terms of taste, aftertaste, mouthfeel, and acceptance. Furthermore, the film forming capacity of the polymers was evaluated and resulted better than single polymers. The drug and polymers showed no major interactions which were displayed by the DSC studies. As per the required results for paper dosage form, all parameters were showing satisfactory results. Formulation F3 was selected as the ideal formulation for the development of paper dosage form. F3 showed a disintegration time less than 35 sec, which shows that the drug will start releasing in less than a minute and more than 60% drug was released in 5 mins which were required for the quick onset of action.

Umakanta Sahoo, Mira Das, Padmolochan Nayak
Abstract
In this paper
β -cyclodextrin (β-CD) grafted chitosan (CS) with MMT was different feed ratio known as (β-CD-g-CS/MMT). The prepared nanocomposites were characterized by XRD, FTIR, SEM, TGA, TDC and swelling in stimulated in different biological fluid. The model drug Cyclophosmide (CYC) was used for controlled drug delivery purpose. From FTIR result was clearly demonstrated that the model drug CYC did not change in any molecular level at β-CD-g-CS/MMT (i.e. at <10 nm scale). Additionally, in DSC result, CYC was interacted with nanocomposites at scale >100 nm level. In vitro drug release system was carried out by Korsmeyer Peppas’s power law. CYC and other drugs like Doxorubicin (DOX) and Curcumin (CUM) were presented exceptional higher drug result in different pH medium. It was observed that CS/MMT was decrease less drug release rate compared to β-CD-g-CS/MMT. So that it can be clearly understood that β-CD-g-CS/MMT grafted nanocomposites have enhanced drug release activity in different pH medium.

T NeelimaRani, Y IndiraMuzib
Abstract
In the present work an investigation was successfully made to formulate and evaluate rosuvastatin rapidmelts by direct compression and sublimation techniques. In direct compression method, as rosuvastatin comes under BCS class II drug, the solubility of the drug should be increased before formulation. For that solid dispersions were prepared with β-CD, PEG2000, and PEG4000 by using coevaporation and kneading method. Among those solid dispersions prepared with β-CD (1:1.5) by using coevaporation method has given better drug entrapment values compared to other solid dispersions. Selected solid dispersions were formulated as rapidmelts by using direct compression method. In direct compression method rapidmelts were prepared by using super disintegrants like ludiflash, crosscaramellosesodium, and lycoat. Those are evaluated for both precompression and post-compression parameters. Rosuvastatin rapidmelts were prepared by sublimation method using subliming agents camphor, menthol, and ammonium bicarbonate. Each subliming agent is used in three different concentrations (2.5,5.0,7.5%). Rapidmelts prepared with the two methods were evaluated for weight variation, hardness, friability, %drug content and disintegration time. The best formulation was subjected to stability testing for 3 and 6 months at 25
oC/60%RH and 40
oC/75%RH. All the prepared formulations compiled with the pharmacopieal limits. The results suggested that R12 formulation has given the best disintegration and dissolution results compared to all other formulations. From the result, it was concluded that rapidmelts prepared by using sublimation method have given a better result than direct compression method. That optimized formulation was further evaluated for
in-vivo studies.

Moringa oleifera Lam.-Based Effervescent Tablets: Design, Formulation and Physicochemical Evaluation
Murdiana H E, Revika E, Rahmawati D, Puspitasari T R, Putri A D, Murti B T
Abstract
Moringa oleifera Lam., locally known as
Kelor, is widely acknowledged as phytopharmaceutical herbal due to the ability of increasing the 58% hemoglobin level in pregnant women as well as preventing the decrease of serum ferritin by 50% leading to anemia. Recently, the need of easy-to-dissolve tablet has been increased upon the natural extract and therefore, the choose of effervescent dosage form is highly preferable. This study was aimed at designing the optimal composition of antianemia effervescent drug based on
Moringa oleifera Lam. leaves extract. The
Moringa leaves extract was produced by maceration method using 70% ethanol. Effervescent tablets were prepared in four formulas based on acid-base (1: 2 and 1: 3) and taste variations (i.e. lemon and strawberry). The tablet was formulated using wet granulation method. Prior to tablet compressing, the granules were tested for the physical properties including water content, contact angle, flowability, tapped index, compactibility, and granule density. In the form of effervescent tablets, the further tests were applied i.e. weight and size uniformity, hardness, and effervescent time. The four designed formulas show excellent properties either for granules or tablet forms. All formulas showed acceptable physical properties of granules and tablets. In regards of acceptability, all formulas yield a fairly bitter taste which is possibly due to the tannins and phenolic compounds of the extract. Addition of flavoring agents, such as lemon and strawberry, is unable to mask the bitter taste of the final tablet. Herein, the first
Moringa leaves effervescent tablet prepared using wet granulation was successfully formulated. This study is possibly advantageous as the bottom line for the further formulation of
Moringa oleifera Lam.-based effervescent products.
