Comparison of in vitroin vivoand in silico bioavailability results of different prednisone tablet formulations to assess the feasibility of possible biowaiver. Rio de Janeiro. The immediate-release solid oral products containing very soluble and permeable drugs are candidates for the biowaiver process. This work aims to compare in vitroin silicoand in vivo data to establish if previously published prednisone oral tablet formulations are biowaiver candidates.
To achieve this goal, permeation studies were conducted on Caco-2 cells. The apparent permeability coefficient for prednisone presented a value of 3. The bioequivalence study shows that the tested and reference product was equivalent. The in silico simulations successfully predicted the pharmacokinetics of the tested and the other two formulations since they were validated with the in vivo study. Both exhibit the same plasma concentration vs. Through the in silico results, it is possible to infer that the other two formulations tested may be bioequivalent concerning the reference product.
This result may be helpful in biowaiver requesting. Toward to reduce costs and the use of human beings in bioequivalence studies, this approach could be an essential way to work in the pharmaceutical industry. El estudio de bioequivalencia muestra que el producto probado y de referencia era equivalente. In silico pharmacokinetic studies could accelerate the registration process for generic drugs applying for biowaiver.
As a biowaiver candidate, the relevance of in silico studies for BCS class I drugs is even more critical, given the regulatory scenario.
It may induce regulatory agencies to take a more in-depth view of the dissolution aspects during stability studies and how in silico previsions may help develop new projects. Pharmaceutical equivalents drug products are considered bioequivalent and, therefore, interchangeable when the bioavailability is not statistically different between the products after administration at the same dose and under similar experimental conditions in a BE study 1.
Prednisone is a glucocorticoid extensively used in clinical practice for inflammatory diseases. It has a biological half-life time of about 3. The permeability rate of prednisone in artificial phospholipid membrane is 0. In Brazil, prednisone is marketed as immediate-release oral tablets at concentrations of 20 mg and 50 mg. Numerous generic formulations of prednisone registered in the Brazilian market prove the BE with the reference product.
These tests require resources and time in the formulation development process. Thus, one of the main discussions among the academic, industrial, and regulatory arena today revolves around biowaivers. A biowaiver account that relative bioavailability or BE tests are not required for drug registration by the regulatory agency when a suitable in vitro assay could replace it 4.
The need for the pharmaceutical industry to obtain a safe tool that allows an in vitro-in vivo correlation IVIVC for a possible biowaiver is increasingly higher. The concept and application of this correlation have been focused attention on universities, pharmaceutical industries, and regulatory sectors.
The correlation of the in silico simulation with the in vitro and in vivo studies can predict the absorption, distribution, metabolism, and elimination of several drugs 5.
Biowaiver procedure could involve an evaluation through computational simulations that delineate a natural or laboratory process. However, to obtain a correlation, this software needs some active pharmaceutical ingredient API input data such as permeability rate, pKa, logP, logD, and solubility 6. Also, the in vitro results combined with in silico simulation to justify a biowaiver for etoricoxib 8.
Even though it is handy in drug bioavailability prediction in the development phase, Brazilian legislation currently does not consider the in silico results to grant exemption or replace bioequivalence studies. In a previous paper, we presented a pre-formulation study by which a prednisone raw material supplier was chosen. Tablet formulations were prepared, and a stability study was conducted to select which one should be scaled up.
Moreover, we monitored dissolution and dissolution profiles during stability study, a not common approach in pharmaceutical literature. Considering the reduction of dissolution during stability studies, it could eventually impact the in vivo performance of the product over time This work compared in vitroin silicoand in vivo data to establish if previously published prednisone oral tablet formulation is an effective candidate for the biowaiver process.
Simultaneously, this paper brings a wholly new perspective of biowaiver attempt helping to understand this process better. After 24 hours, the culture medium was removed from wells, and cells were placed in contact with a Samples were stayed connected with Caco-2 cells for 3 hours and then aspirated. Thus, the cells were treated with 2. Samples were subjected to permeability tests through Caco-2 cell monolayers during passage Cells were seeded onto polycarbonate filters 0.
This solution was used in the apical compartment donor. HBSS pH 7. Prednisone solution at Two hundred microliters of this solution were added into the apical compartment of the cell monolayer.
The apparent permeability coefficient P app was calculated using Eq. Equation 1. An open, randomized, cross-over study was conducted with two treatments, two sequences, and two periods, in which volunteers received, in each period, the test or the reference formulation. The confinement period was 24 hours. Blood samples for determination of plasma concentration of prednisolone were collected before administration and up to 24 hours later at pre-established intervals. The ACAT model describes the gastrointestinal tract like compartments considering drug unreleased drug, dissolved drug, precipitated drug and physiology luminal volume, pH, transit time characteristics.
Once integrated into the PK information, like distribution volume, clearance, and half-life time, it is possible to observe the simulated drug kinetic absorption and exposition in the gastrointestinal tract.
The software has three main input modules: compound, physiology, and pharmacokinetics. The physicochemical solubility, permeability, pKa and drug dosage form tablet, dose, particle size properties were inputted at the compound module. These data were taken from the literature or experimentally determined Table 1. The solubility data was determined in pH 1. Table 1. Input parameters used for the prednisone IR tablet absorption model.
The absorption gradient coefficient C1-C4 was used to calculate the absorption scale factors ASF and scale the effective permeability to account for absorption rate variations that differ from one compartment to another 18 In the pharmacokinetic module, the used data were obtained from the bioequivalence study of the biobatch P, as described above item 2. The best model parameters were then imported into the pharmacokinetic module to enable the in silico plasma concentration versus time data 818 Through Eq.
Equation 2. The cytotoxicity assessment was performed to determine whether concentrations of After 21 days of culture, the mean transepithelial resistance TEER of the Caco-2 cell monolayer was At minutes, prednisone permeation reached Figure 1.
The apparent permeability coefficient P app for prednisone was calculated from the mean of 5 determinations of the permeability test and presented a value of 3. The mean plasma concentration vs. The pharmacokinetic parameters analyzed in the study are described in Table 2.
Table 2. Pharmacokinetic parameters obtained from the mean plasma concentration versus prednisolone time curve. According to the estimated geometric means ratio between C max and the AUC 0-t for batches P, and R the results obtained for these parameters were Therefore, the formulations under study are bioequivalent Figure 2.

The predicted outputs and bioavailability in vivo were almost similar. According to the predicted plasma concentration-time curves, the biobatch P show an in vivo performance equivalent to the reference product, as proven by the BE studies Figure 2. Table 3. Simulation of the percentage absorbed of prednisone biobatch P along with the compartments of the gastrointestinal tract. Figure 3. Plasma concentration vs. TEER values were compatible with those reported in the literature for mature monolayers 12 As previously mentioned, prednisone belongs to BCS class I.
The P app obtained in this study for this drug 3. According to Vogt and collaborators 2there are very limited studies reporting the in vitro permeability of prednisone since it is a prodrug. However, the FDA Guidance 1 states that the prodrug permeability should be measured when the conversion occurs after GI membrane permeation.
So, the results about Caco-2 cells prednisone permeability could be beneficial in a biowaiver decision. In silico absorption model for prednisone immediate-release tablet. According to the drug solubility of previous studies and permeability analyzed in this work, prednisone is highly soluble and absorbed in the intestinal tract.
The evaluation of the in vivo plasma concentration vs. It means that the drug promptly occupies the central compartment, and the plasma concentration decrease depends only on the elimination rate constant, which follows a first-order process 27 The predicted outputs and BA in vivo Table 4 suggest that the in silico absorption model based on the Table 1 data successfully simulate the in vivo bioavailability of prednisone IR tablets.

Duque and co-workers successfully used the ACAT model in BA simulated of fluconazole, a BCS class I drug, showing that the prediction model was also valuable for generic and reference drugs As mentioned, the biowaiver is requested for BCS class I drugs when using immediate-release tablets.
In this context, a predictive in vitro dissolution could replace the bioequivalence study Once the in silico absorption model was developed for prednisone IR tablets, it becomes possible that the bioavailability simulation helps during the optimization of the formulation process. By evaluating the in vivo and in silico data, it is possible to infer that an in vivo study is probably unnecessary for these, suggesting the bioequivalence between the MEST 01, MEST 02, R, and biobatch P Table 4.
Previously, the dissolution tests were conducted in purified water, as recommended by the Brazilian compendia All the products that meet the requirements of the dissolution rate still showed an in silico performance equivalent to the reference product. In some cases, the in vitro dissolution method was not discriminative for the in vivo process. Al-Tabakha and co-workers evaluated different products containing amoxicillin and potassium clavulanate that was considered bioequivalent but presenting differently in vitro dissolution profiles The use of purified water as dissolution media, although recommended for quality control tests 10 , may not be adequate for evaluating pharmaceutical equivalence.
Although the results present by this study provide a biowaiver favorable data based on the in silico pharmacokinetic study and the BCS, prednisone is at the borderline of the current criteria of BCS class I. The biowaiver of prednisone must be carefully evaluated considering its indication, therapeutic index, pharmacokinetic performance, and the possibility of drug-excipients interaction 2.
Due to many marked generic products of prednisone and other class I drugs, the use of different formulation excipients could modify their dissolution and oral absorption. Therefore, in vivo bioequivalence studies are still needed. The present study evaluates the in silico bioavailability simulations comparing these data with in vivo ones in order to establish if previous published prednisone oral tablet formulation is a valid candidate for the biowaiver process. The simulated plasma concentration vs.
In order to confirm this hypothesis, a predictive dissolution study should be applied. This work turns available the bioavailability profile obtained in human volunteers and compares reference and tests drug products, which is not common in the offered publications.
More than that, it presents a viable in silico model to simplify post-approval changes in the regulatory scenario. Prednisone is classified as a BCS class I or borderline class I drug and a promising candidate for biowaiver. However, a careful evaluation of the excipients used is necessary to claim it.
