Abstract
Lactose is an excipient used extensively for bulking, diluting, and molding active pharmaceutical ingredients in tablet manufacturing. Particularly, granulated lactose (GL) intended for direct powder compression has distinct properties due to differences in manufacturing methods. It contributes to handling blended powders for tableting and tablet quality. In this study, we aimed to compare the functions of different forms of GL added as excipients during direct powder compression on the tablet properties and the effect of magnesium stearate (Mg-S) used as a lubricant on each type of GL. Different GL types obtained using different manufacturing methods (agitated granulation, GL-AG; spray-dried granulation, GL-SD; fluidized bed granulation, GL-FB) were blended with maize starch, low-substituted hydroxypropyl cellulose, and paracetamol in a V-type blender for 10 min. Mg-S was added at varying amounts (0.1, 1.0, and 2.0%) and blending times (5, 10, and 30 min) for the nine types of blended powders for tableting formulation. The powders were tableted, and the tablets were evaluated for weight and drug loading variations, tensile strength, friability, and disintegration time. When tablets with the same blending conditions were compared, the tensile strength and disintegration time were in the order of GL-FB > GL-SD > GL-AG. For each GL, we analyzed the effects of changes in the added amount of Mg-S and blending time using contour plots, evaluated the effects of blending conditions on tablet properties, and determined the target tablet properties. We investigated the optimization of the lubricant blending conditions to obtain suitable tablets.

Abstract
Direct compression is a tableting technique that involves a few steps in non-demanding manufacturing conditions. High strength and rapid disintegration of tablet formulations were previously achieved through the addition of cellulose nanofibers (CNFs), which have recently attracted attention as a high-performance biomass material. However, CNF addition results in greater variation in tablet weight and drug content, potentially due to differences in particle size between CNF and other additives. Herein, we used pulverized CNF to evaluate the effect of CNF particle size on the variation in tablet weight and drug content. Tablet formulations consisted of CNF with different particle sizes (approximately 100 µm [CNF100] and 300 µm [CNF300], at 0, 10, 30, or 50%), lactose hydrate, acetaminophen, and magnesium stearate. Ten powder formulations with different particle sizes and CNF concentrations were prepared; thereafter, the tablets were produced using a rotary tableting press with a compression force of 10 kN. The variation in weight and drug content as well as the tensile strength, friability, disintegration time, and drug dissolution of tablets were evaluated. CNF100 addition to the tablets reduced the weight and drug content variation to a greater extent than CNF300 addition. Using CNF300, we produced tablets of sufficient strength and short disintegration time. These properties were also achieved with CNF100 addition. Our findings suggest that adding CNF of small particle size to the tablet formulation can reduce the variation in weight and drug content while maintaining high strength and short disintegration time.

Abstract
In recent years, orally disintegrating (OD) tablets have been continuously improved to increase efficacy. Herein, we focused on the benefits of cellulose nanofiber (CNF), a highly functional material, in OD tablet manufacturing. We studied its effects on the physical properties of tablets during manufacture. The analyzed tablet formulations included different content CNF (0-50%; 6 preparations), lactose hydrate, acetaminophen, and magnesium stearate (Mg-St). We measured the angles of repose and evaluated the flowability of the powder. Tablets were prepared on a tabletop and rotary tableting presses, whereafter their weight, drug content, hardness, friability, and disintegration time were evaluated. Although CNF addition slightly reduced powder flowability, continuous tableting was feasible via direct powder compression. Tablet hardness (~40 N) was comparable between CNF-containing (20%) tablets and those prepared with crystalline cellulose under 10 kN compression force. Disintegration time (~30 s) was similar between CNF-supplemented tablets and those supplemented with low-substituted hydroxypropyl cellulose, crospovidone, or croscarmellose sodium. At higher CNF fractions, tablet hardness increased, while friability decreased. Adding ≥30% CNF prolonged the tablet disintegration time. To set the optimized manufacturing condition for ensuring the desired tablet physical properties, we created contour plots for evaluating the effects of CNF concentration and compression force on hardness and disintegration time. A CNF concentration of 10-20% and a compression force of 12-13 kN would allow for the preparation of tablets with a hardness ≥30 N and a disintegration time ≤60 s. Altogether, addition of CNF to the OD tablet formulation for direct powder compression enhanced hardness and disintegration.

Abstract
Traditionally, the leafy part of Andrographis paniculata and Moringa oleifera have been widely reported to manage hypertension. Investigation of its pharmacological actions justifies its use. As part of formulation studies to standardize them, this study focused on their compaction and compression properties. Compacts equivalent to 250 mg of A. paniculata and M. oleifera were produced by compressing powders and granules at various compression pressure. Results show that M. oleifera met the WHO limit for ash values. Relative density values for granulated batches were higher, while their moisture content values were lower when compared to those of direct compression. The result from Heckel plots shows that batches deform mainly by plastic flow. For Kawakita plots, values of 1/b show that batches containing microcrystalline cellulose were less cohesive. The plot of tensile strength signifies that granulated batches achieved maximum crushing strength faster at low pressure. Formulations containing maize starch were shown to have higher percent porosity, and granulated batches gave higher values for apparent density-pressure relationship and lower friability values. Tablets produced by the wet granulation method showed better compression and compaction properties than those formulated by direct compression.

Abstract
This paper presents new machine vision-based methods for indirect real-time quantification of ultralow drug content during continuous twin-screw wet granulation and tableting. Granulation was performed with a solution containing carvedilol (CAR) as API in the ultralow dose range (0.05w/w% in the granule) and the addition of riboflavin (RI) as a coloured tracer. An in-line calibration in the range of 0.047-0.058 w/w% was prepared for the measurement of CAR concentration using colour analysis (CA) and particle size analysis (PSA), and the validation with HPLC resulted in respective relative errors of 2.62% and 2.30% showing great accuracy. To improve the technique, a second in-line calibration was conducted in a broader CAR concentration range of 0.039-0.063 w/w% utilizing only half the amount of RI (0.045 w/w%), while doubling the output of the granulation line to 2 kg/h, producing a relative error of 4.51% and 4.29%, respectively. Finally, it was shown that the CA technique can also be carried on to monitor the CAR content of tablets in the 42-62 μg dose range with a relative error of 5.20%. Machine vision was proven to be a potent indirect method for the in-line, determination and monitoring of ultralow API content during continuous manufacturing.

Abstract
Objective:
Adequate glycemic control in diabetes patients requires oral combination therapy.
Saxagliptin is a dipeptidyl peptidase-4 inhibitor having fewer adverse effects, and metformin
is the first-line medicine for diabetes treatment. The aim of this research work is to develop a bilayer
tablet of saxagliptin and metformin in fixed-dose combination (FDC) using quality by design
(QbD) to acquire the immediate release of saxagliptin and sustained release of metformin from bilayer
tablet to ultimately achieve superior patient compliance.
Methods:
The development of the bilayer tablet was done in four stages using QbD. In the first
step, quality target product profile (QTPP) of bilayer tablet was defined, and critical quality attributes
(CQAs) were identified by risk estimation matrix and taguchi design; an immediate release
saxagliptin layer was optimized in the second step, optimization of sustained-release metformin layer
was carried out in the third step, and in the final step, bilayer tablet was prepared and characterized.
The effect of independent parameters, i.e., magnesium stearate level (X1), kneading time (X2)
and lubrication time (X3) on Carr’s Index (Y1), percentage relative standard deviation of content
uniformity (Y2) and drug release at 30 minutes (Y3), were estimated for optimization of immediate
release saxagliptin layer using Box-Behnken design (BBD). The effect of independent parameters,
i.e., hydroxypropyl methylcellulose level (X4), compritol level (X5) and magnesium stearate level
(X6) on Carr’s Index (Y4), drug release at 2 h (Y5), drug release at 5 h (Y6) and drug release at 10 h
(Y7) were estimated for optimization of sustained-release metformin layer using BBD.
Results:
The optimized composition of immediate release saxagliptin layer estimated using numerical
optimization by Design expert was 0.88% (X1), 15 minutes (X2) and 3.85 minutes (X3) with predicted
variables, i.e., 10.59% (Y1), 3.16% (Y2) and 85% (Y3). The optimized composition of sustained-
release saxagliptin layer predicted through numerical optimization was 30% (X4), 3.36%
(X5) and 0.9% (X6) having 10.89% (Y4), 43.44% (Y5), 60% (Y6) and 85.14% (Y7). In-vitro dissolution
study of bilayer tablet showed immediate release of Saxagliptin (approximately 85% in 30 minutes)
and sustained release of metformin illustrating 43.21±1.21, 60.86±2.96 and 86.26±1.38%
drug release at 2, 5 and 10 h, respectively. The release exponent for the Korsmeyer-Peppas model
for Saxagliptin and metformin was 0.237 (<0.45) and 1.536 (n>0.85), indicating Fickian and super
case II transport drug release behavior, respectively.
Conclusion:
By QbD approach, bilayer tablet containing saxagliptin and metformin was successfully
developed, and influence of various formulation parameters on CQAs of drug products was understood
with fewer experiments. This leads to the conclusion that cost can be reduced using QbD
in the development of FDC for improving patient compliance.

Abstract
This study aims to examine the contribution of nanoporous silica entrapped lipid-drug complexes (NSCs) in improving the solubility and bioavailability of dutasteride (DUT). An NSC was loaded with DUT (dissolved in lipids) and dispersed at a nanoscale level using an entrapment technique. NSC microemulsion formation was confirmed using a ternary phase diagram, while the presence of DUT and lipid entrapment in NSC was confirmed using scanning electron microscopy. Differential scanning calorimetry and X-ray diffraction revealed the amorphous properties of NSC. The prepared all NSC had excellent flowability and enhanced DUT solubility but showed no significant difference in drug content homogeneity. An increase in the lipid content of NSC led to an increase in the DUT solubility. Further the NSC were formulated as tablets using D-α tocopheryl polyethylene glycol 1000 succinate, glyceryl caprylate/caprate, and Neusilin®. The NSC tablets showed a high dissolution rate of 99.6% at 30 min. Furthermore, NSC stored for 4 weeks at 60 °C was stable during dissolution testing. Pharmacokinetic studies performed in beagle dogs revealed enhanced DUT bioavailability when administered as NSC tablets. NSC can be used as a platform to develop methods to overcome the technical and commercial limitations of lipid-based preparations of poorly soluble drugs.

Abstract
Direct powder compression is the simplest tablet manufacturing method. However, segregation occurs when the drug content is low. It is difficult to assure drug content uniformity in these cases. In this study, we evaluated microcrystalline cellulose (MCC) as a segregation inhibitor in pharmaceutical powders. We assessed the influence of MCC concentration and mixing time on the physical properties of tablets. The tablet formulation comprised acetaminophen, lactose hydrate, cornstarch, MCC (0%, 10%, or 20%), croscarmellose sodium, and magnesium stearate (Mg-St). All powders except Mg-St were premixed for 5, 15, or 25 min. Mg-St was then added and mixed for 5 min to prepare nine pharmaceutical powders. Flowability index and practical angle of internal friction were measured. Tablets were also prepared, and their weight variation, hardness, friability, disintegration time, and drug content variation were evaluated. MCC slightly decreased pharmaceutical powder flowability. Tablet hardness increased and disintegration time decreased with increasing MCC concentration. MCC mixed for ≥ 15 min also significantly lowered drug content variation. A contour plot was prepared to assess the effect of MCC concentration and mixing time on the physical properties of tablets. It was determined that tablets with 50-80 N hardness, ≤ 3.5 min disintegration time, and ≤ 3% drug content variation can be prepared when MCC concentration is 6.5-8.5% and the mixing time is 19-24 min. Therefore, MCC is effective as a segregation inhibitor, and the addition of MCC to tablet formulation improves drug content uniformity.

Abstract
The objective of this study was to examine the influence of drug amount and mixing time on the homogeneity and content uniformity of a low-dose drug formulation during the dry mixing step using a new gentle-wing high-shear mixer. Moreover, the study investigated the influence of drug incorporation mode on the content uniformity of tablets manufactured by different methods. Albuterol sulfate was selected as a model drug and was blended with the other excipients at two different levels, 1% w/w and 5% w/w at impeller speed of 300 rpm and chopper speed of 3000 rpm for 30 min. Utilizing a 1 ml unit side-sampling thief probe, triplicate samples were taken from nine different positions in the mixer bowl at selected time points. Two methods were used for manufacturing of tablets, direct compression and wet granulation. The produced tablets were sampled at the beginning, middle, and end of the compression cycle. An analysis of variance analysis indicated the significant effect (p < .05) of drug amount on the content uniformity of the powder blend and the corresponding tablets. For 1% w/w and 5% w/w formulations, incorporation of the drug in the granulating fluid provided tablets with excellent content uniformity and very low relative standard deviation (∼0.61%) during the whole tableting cycle compared to direct compression and granulation method with dry incorporation mode of the drug. Overall, gentle-wing mixer is a good candidate for mixing of low-dose cohesive drug and provides tablets with acceptable content uniformity with no need for pre-blending step.
