    ABSTRACT: Cocrystal forming ability of antiviral drug acyclovir (ACV) with different coformers was studied. Three cocrystals containing ACV with fumaric acid, malonic acid, and dl-tartaric acid were isolated. Methods of cocrystallization included grinding with dropwise solvent addition and solvent evaporation. The cocrystals were characterized by powder X-ray diffraction, differential scanning calorimetry, and thermogravimetric analysis. The crystal structure of the cocrystal with fumaric acid as conformer was determined by single crystal X-ray diffraction. Formation of supramolecular synthon was observed in the cocrystal. Stability with respect to relative humidity for the three cocrystals was evaluated. The aqueous solubility of the ACV-cocrystal materials was significantly improved with a maximum of malonic acid cocrystal, which was about six times more soluble at 35°C compared with that of parent ACV. The dissolution profile indicates that at any particular dissolution time, the concentration of cocrystals in the solution was higher than that of the parent ACV, and malonic acid cocrystals had a maximum release of about twice than the hydrated ACV. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci

    ABSTRACT: We evaluated two human immunodeficiency virus (HIV) protease inhibitors, atazanavir (ATV) and darunavir (DRV), for pH-dependent solubility, lipid binding, and drug release from lipid nanoparticles (LNPs). Both ATV and DRV incorporated into LNPs composed of pegylated and non-pegylated phospholipids with nearly 100% efficiency, but only ATV-LNPs formed stable lipid-drug particles and exhibited pH-dependent drug release. DRV-LNPs were unstable and formed mixed micelles at low drug-lipid concentrations, and thus are not suitable for lipid-drug particle development. When ATV-LNPs were prepared with ritonavir (RTV), a metabolic and cellular membrane exporter inhibitor, and tenofovir (TFV), an HIV reverse-transcriptase inhibitor, stable, scalable, and reproducible anti-HIV drug combination LNPs were produced. Drug incorporation efficiencies of 85.5 ± 8.2, 85.1 ± 7.1, and 6.1 ± 0.8% for ATV, RTV, and TFV, respectively, were achieved. Preliminary primate pharmacokinetic studies with these pH-responsive anti-HIV drug combination LNPs administered subcutaneously produced detectable plasma concentrations that lasted for 7 days for all three drugs. These anti-HIV LNPs could be developed as a long-acting targeted antiretroviral therapy. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: In hair follicle (Hf) cells, the type-2 5-α-reductase enzyme, implicated in androgenetic alopecia, is selectively inhibited by finasteride (FNS). Because an effective topical formulation to deliver FNS to Hf is currently unavailable, this investigation aimed at evaluating in vitro FNS skin permeation and retention through and into hairless rat and human abdominal skin. Four hydroxypropyl chitosan (HPCH)-based formulations (P-08-012, P-08-016, P-08-063, and P-08-064) and one anhydrous formulation without HPCH (P-10-008) were tested. The pharmacokinetics in plasma and skin after application of P-08-016 or P-10-008 on dorsal rat skin with single and repeated doses was investigated. P-08-016 performed the best in driving FNS to the reticular dermis without producing a high transdermal flux. Neither the in vivo single nor the repeated dose experiments produced plasma levels of FNS and no differences were found between formulations concerning skin retention. No increase in the amount of drug retained in the skin was obtained with the repeated dose experiment. In conclusion, the HPCH-based formulation P-08-016 might represent an alternative to systemic therapy for its ability to promote a cutaneous depot of FNS in the region of hair bulbs, minimizing systemic absorption even after repeated treatments. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: The impact of thermal stress on indomethacin (IMC)-nicotinamide (NIC) cocrystal formation with or without neat cogrinding was investigated using differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) microspectroscopy, and simultaneous DSC-FTIR microspectroscopy in the solid or liquid state. Different evaporation methods for preparing IMC-NIC cocrystals were also compared. The results indicated that even after cogrinding for 40 min, the FTIR spectra for all IMC-NIC ground mixtures were superimposable on the FTIR spectra of IMC and NIC components, suggesting there was no cocrystal formation between IMC and NIC after cogrinding. However, these IMC-NIC ground mixtures appear to easily undergo cocrystal formation after the application of DSC determination. Under thermal stress induced by DSC, the amount of cocrystal formation increased with increasing cogrinding time. Moreover, simultaneous DSC-FTIR microspectroscopy was a useful one-step technique to induce and clarify the thermal-induced stepwise mechanism of IMC-NIC cocrystal formation from the ground mixture in real time. Different solvent evaporation rates induced by thermal stress significantly influenced IMC-NIC cocrystal formation in the liquid state. In particular, microwave heating may promote IMC-NIC cocrystal formation in a short time. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: An observation of visible particulate matter was made during formulation development of a mAb and investigations initiated to understand the colloidal instability of the formulation. It was observed that there was a loss of polysorbate in the IgG formulation and concurrent hydrolysis of polysorbate 80 (PS80) into fatty acid, polyethylene glycol (PEG), and pegylated sorbitan in the presence of mAb A. This observation was confirmed with two other mAb development programs (mAb B and mAb C) that used PS80 and formed particulate, but was absent in any placebo sample tested. Comparative analysis to acid, base and esterase hydrolysis, and exposure to the oxidation reagents Iron(II) and tert-Butyl hydroperoxide demonstrates that the observed reaction is reproduced by a biologic (enzymatic) mechanism. Monooleates of PS80, including the sorbitan and PEG oleates, are hydrolyzed first, showing a slower reaction with higher-order oleates. This leads to a change in the composition of the formulation over time where PS85 becomes the predominant component of the original surfactant remaining in solution. Data suggest that there is a lipid-specific mechanism rather than a general biologic hydrolysis mechanism that hydrolyzes oleate esters of PS80 increasing the risk that colloidal IgG particles will form in mAb drug product. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: In this study, injectable microspheres were developed for the local treatment of joint degeneration in rheumatoid arthritis (RA). Microspheres loaded with triamcinolone (TA), a corticosteroid drug, and/or raloxifene (Ral), a cartilage regenerative drug, were prepared with a biodegradable and biocompatible polymer, polycaprolactone (PCL). Microspheres were optimized for particle size, structural properties, drug release, and loading properties. In vitro release of Ral was very slow because of the low solubility of the drug and hydrophobic nature of PCL. However, when coloaded with TA, both drugs were released at higher amounts compared with their single forms. Smallest particle sizes were obtained in dual drug-loaded microspheres. In vitro cytotoxicity tests showed biocompatibility of microspheres. In vivo bioefficacy of these microspheres was also examined in adjuvant-induced arthritis model in rats. In vivo histological studies of control groups showed development of RA with high median lesion score (5.0). Compared with control and intra-articular free drug injections, microsphere treatment groups showed lower lesion scores and better healing outcomes in histological evaluations. Results suggest that a controlled delivery system of TA and RAL by a single injection in inflamed joints holds promise for healing and suppressing inflammation. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: Photoprotective potential and biological consequences (mutagenic potential) of octyl-dimethyl-PABA (ODP), titanium dioxide (TiO2 ), and montmorillonite (MMT) upon ultraviolet B (UVB) irradiation, alone and in different associations [physical mixtures (PMs)], were evaluated using a Saccharomyces cerevisiae ogg1 mutant (deficient) strain. In addition, we developed and characterized a delaminated TiO2 -pillared MMT, called the TiO2 -MMT nanocomposite (NC), which was also investigated in terms of its photoprotective and mutagenic potential. Overall, our results revealed an interesting TiO2 -MMT NC endowed with antimutagenic activity that can be associated to organic sunscreen molecule (ODP) and still maintain its positive effect, whereas its respective PM is unable to grant antimutagenic protection against UVB. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: A method for concentration of protein solutions is required for high-dosage protein formulation. Here, we present a precipitation-redissolution method by poly(amino acid) for proteins, including therapeutic enzymes, antibodies, and hormones. The proteins were fully precipitated by the addition of poly-l-lysine or poly-l-glutamic acid at low ionic strength, after which precipitate was dissolved at physiological ionic strength. The activities and secondary structures of redissolved proteins, especially antibodies, were almost identical to the native state. The precipitation-redissolution method is a simple and rapid technique for concentration of protein formulations. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: The objective of the present research was to study the feasibility of using near-infrared (NIR) and Fourier transform infrared (FTIR)-based chemometric models in quantifying crystalline and amorphous tacrolimus from its sustained-release amorphous solid dispersion (ASD). ASD contained ethyl cellulose, hydroxypropyl methyl cellulose, and lactose monohydrate as carriers, and amorphous form of tacrolimus in it was confirmed by X-ray powder diffraction. Crystalline physical mixture was mixed with ASD in various proportions to prepare sample matrices containing 0%-100% amorphous/crystalline tacrolimus. NIR and FTIR of the samples were recorded, and data were mathematically pretreated using multiple scattering correction, standard normal variate, or Savitzky-Golay before multivariate analysis, partial-least-square regression (PLSR), and principle component regression (PCR). The PLSR models were more accurate than PCR for NIR and FTIR data as indicated by low value of root-mean-squared error of prediction, standard error of prediction and bias, and high value of R(2) . Additionally, NIR data-based models were more accurate and precise than FTIR data models. In conclusion, NIR chemometric models provide simple and fast method to quantitate crystalline tacrolimus in the ASD formulation. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: A responsive antioxidant system constituted from quercetin inserted into poly[N,N-dimethylacrylamide-co-3, 9-divinyl-2, 4, 8, 10-tetraoxaspiro (5.5) undecane] through a semi-imprinted procedure was evaluated. A continuous magnetic field (MF) was used during supramolecular structure preparation. The strength of coupling quercetin was evaluated based on the template release from the polymeric matrices, as well as to what extent quercetin reloaded into the polymer matrix in prescribed conditions-with or without the MF presence-shows antioxidant properties. The antioxidant activity of the complex was investigated by radical inhibitor activity method using 2, 2-diphenyl-l-picrylhydrazyl. The evaluation of the homogeneity distribution of the quercetin inside the polymeric network was made by near-infrared chemical imaging and correspondingly statistical analysis. For in vivo biocompatibility investigation, granuloma test in rats was performed correlated with the activity of enzymes involved in oxidative stress as well as immunologic effects of tested supramolecular complexes that include quercetin as therapeutic agent. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: N-palmitoyl-N-monomethyl-N,N-dimethyl-N,N,N-trimethyl-6-O-glycolchitosan (GCPQ) is a self-assembling polymer, which enables the oral bioavailability of peptide and hydrophobic drugs. In preparation for clinical testing, here we examine GCPQ's synthesis reproducibility, pKa, thermal, and rheological properties. GCPQ was synthesised by acid degradation of glycol chitosan (GC), reaction with palmitic acid N-hydroxysuccinimide (PNS) and methylation. A GC monomer, PNS molar feed ratio of 0.92 together with a gravimetric feed ratio for N-palmitoyl-6-O-glycolchitosan, methyl iodide of 3.3, reproducibly produces GCPQ48 (Mw = 19.9 ± 9.9 kDa, Mn = 13.1 ± 2.4 kDa, mol % palmitoylation = 23 ± 2.7, mol % quaternisation = 10 ± 0.23, n = 56). GCPQ48 decomposes at 218 ± 4.3°C, is glassy at room temperature (Tg = 164.4 ± 8.5°C), is a weak base (pKa = 5.99 ± 0.15), and produces micellar dispersions at neutral pH. Below a concentration of 0.07 g mL(-1) , GCPQ48 dispersions showed Newtonian rheological behaviour but at higher concentrations, the polymer undergoes shear thinning because of the chain disentanglement at high shear rates. GCPQ48 forms a network of micelles and concentrated (0.09 g mL(-1) ) dispersions are viscoelastic, with the storage modulus exceeding the loss modulus at high frequencies. Solid GCPQ48 was stable when stored at room temperature for 18 months. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: The objective of this study was to elucidate effects of formulation and process variables on the physical forms of freeze-dried myo-inositol. Physical properties of myo-inositol in frozen solutions, freeze-dried solids, and cooled heat-melt solids were characterized by powder X-ray diffraction (PXRD), thermal analysis (differential scanning calorimetry [DSC] and thermogravimetric), and simultaneous PXRD-DSC analysis. Cooling of heat-melt myo-inositol produced two forms of metastable anhydrate crystals that change to stable form (melting point 225°C-228°C) with transition exotherms at around 123°C and 181°C, respectively. Freeze-drying of single-solute aqueous myo-inositol solutions after rapid cooling induced crystallization of myo-inositol as metastable anhydrate (transition at 80°C-125°C) during secondary drying segment. Contrarily, postfreeze heat treatment (i.e., annealing) induced crystallization of myo-inositol dihydrate. Removal of the crystallization water during the secondary drying produced the stable-form myo-inositol anhydrate crystal. Shelf-ramp slow cooling of myo-inositol solutions resulted in the stable and metastable anhydrous crystal solids depending on the solute concentrations and the solution volumes. Colyophilization with phosphate buffer retained myo-inositol in the amorphous state. Crystallization in different process segments varies crystal form of freeze-dried myo-inositol solids. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: Pathophysiological changes of infection or inflammation are associated with alterations in the production of numerous absorption, distribution, metabolism and excretion-related proteins. However, little information is available on the effects of inflammation on the expression levels and activities of ATP-binding cassette (ABC) transporters. We examined the effect of acute (on day 7) and chronic (on day 21) inflammation on the expression of ABC transporters in some major tissues in rat. Adjuvant-induced arthritis (AA) in rats was used as an animal model for inflammation. The mRNA levels of mdr1a and mdr1b encoding P-glycoprotein (P-gp) decreased significantly in livers of AA rats on day 21. Hepatic protein levels of P-gp, Mrp2, and Bcrp decreased significantly in membranes but not homogenates of AA rats after 7 days and after 21 days of treatment with adjuvant. Contrary to liver, protein levels of P-gp and Mrp2, but not Bcrp in kidney, increased significantly in membranes. The biliary excretion of rhodamine 123 was decreased in rats with chronic inflammation owing to decreases in efflux activities of P-gp. Our results showed that the expression of transporters in response to inflammation was organ dependent. In particular, hepatic and renal P-gp and Mrp2 exhibited opposite changes in membrane protein levels. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: Resveratrol (RES) and curcumin (CUR) have free radical scavenging ability and potential chemosensitizing effects. Doxorubicin hydrochloride (DH) is a potent chemotherapeutic with severe cardiotoxicity. We hypothesize that RES and CUR co-loaded in Pluronic(®) micelles and co-administered with DH will result in cardioprotective effects while maintaining/improving DH anti-proliferative effect in vitro. RES-CUR at a molar ratio of 5:1 in F127 micelles (mRC) were prepared and characterized for size, drug loading, and release. In vitro cell viability and apoptosis assays in ovarian cancer cells (SKOV-3) and cardiomyocytes (H9C2) with either individual drugs or RES-CUR or mRC in combination with DH were conducted. Combination index (CI) analysis was performed to determine combination effects. Reactive oxygen species (ROS) were quantified in H9C2 for DH, and combinations. The mRC solubilized 2.96 and 0.97 mg/mL of RES and CUR, respectively. Cell viability and CI studies indicated that the combinations were synergistic in SKOV-3 and antagonistic in H9C2 cells. Caspase 3/7 activity in combination treatments was lower than with DH alone in both cell lines. ROS activity was restored to baseline in H9C2 cells in the micelle combination groups. Co-administration of mRC with DH in vitro mitigates DH-induced cardiotoxicity through reduction in apoptosis and ROS while improving DH potency in ovarian cancer cells. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: Previously, we reported a novel pressurized olfactory drug (POD) delivery device that deposits aerosolized drug preferentially to upper nasal cavity. This POD device provided sustained central nervous system (CNS) levels of soluble morphine analgesic effects. However, analgesic onset of less soluble fentanyl was more rapid but brief, likely because of hydrophobic fentanyl redistribution readily back to blood. To determine whether fentanyl incorporated into an aerosol-stable liposome that binds to nasal epithelial cells will enhance CNS drug exposure and analgesic effects and reduce plasma exposure, we constructed Arg-Gly-Asp (RGD) liposomes anchored with acylated integrin-binding peptides (palmitoyl-Gly-Arg-Gly-Asp-Ser). The RGD liposomes, which assume gel phase membrane structure at 25°C, were stable under the stress of aerosolization as only 2.2 ± 0.5% calcein leakage was detected. The RGD-mediated integrin binding of liposome is also verified to be unaffected by aerosolization. Rats treated with fentanyl in RGD liposome and POD device exhibited greater analgesic effect, as compared with the free drug counterpart (AUCeffect = 1387.1% vs. 760.1% MPE*min), whereas approximately 20% reduced plasma drug exposure was noted (AUC0-120 = 208.2 vs. 284.8 ng min/mL). Collectively, fentanyl incorporated in RGD liposomes is physically and biologically stable under aerosolization, enhanced the overall analgesic effects, and reduced plasma drug exposure for the first 2 h. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: The stability of three commercial "fast-acting" insulin analogs, insulin lispro, insulin aspart, and insulin glulisine, was studied at various concentrations of phenolic preservatives (phenol and/or meta-cresol) during 9 days of incubation at 37°C. The analysis by both size-exclusion and reversed-phase chromatography showed degradation of lispro and aspart that was inversely dependent on the concentration of phenolic preservatives. Insulin glulisine was much more stable than the other analogs and showed minimal degradation even in the absence of phenolic preservatives. With sedimentation velocity ultracentrifugation, we determined the preservatives' effect on the insulins' self-assembly. When depleted of preservatives, insulin glulisine dissociates from higher molecular weight species into a number of intermediate molecular weight species, in between monomer and hexamer, whereas insulin aspart and insulin lispro dissociate into monomers and dimers. Decreased stability of insulin lispro and insulin aspart seems to be because of the extent of dissociation when depleted of preservative. Insulin glulisine's dissociation to intermediate molecular weight species appears to help minimize its degradation during incubation at 37°C. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.

    ABSTRACT: The purpose of this study was to investigate the effect of preparation methods on cocrystallization between baicalein (BE) and nicotinamide (NCT), their intermolecular interaction, and to demonstrate that BE-NCT cocrystal can achieve the simultaneous enhancement in solubility, dissolution, and oral bioavailability of BE. The cocrystals from three preparation methods have the similar differential scanning calorimetry thermograms and X-ray powder diffraction patterns. Compared with crystalline BE, BE-NCT cocrystal has significantly improved the solubility and dissolution of BE. In addition, the cocrystal exhibits a 2.49-fold higher peak plasma concentration (Cmax ) and 2.80-fold higher area under the curve (AUC) in rats. This prominent improvement in oral bioavailability is even greater than the previously reported BE nanocrystal. This investigation enriched the present understanding of cocrystals on their behavior in vitro and in vivo, and built the groundwork for future development of BE as a promising compound into efficacious drug products. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.
