8 Even though the existing literature contains information on the role of seasonal variations in the effects of some drugs on patients prepared for coronary artery bypass grafting GW4064 supplier surgery (CABG),9 precious little is currently available on the possible effects of seasonal variations on the outcome of patients

following CABG.1 The aim of this study was to assess the short-term outcome of post-CABG patients in the four seasons to seek any possible correlation between seasonal variations and CABG outcome. Patients and Methods The data on all patients who underwent CABG between January 2007 and December 2009 Inhibitors,research,lifescience,medical in two private hospitals in Shiraz, Iran were analyzed. The seasons were defined Inhibitors,research,lifescience,medical as spring (March 21 to June 21), summer (June 22 to September 22), autumn (September 23 to December 21), and winter (December 22 to March 20). In-hospital mortality, length of Intensive Care Unit (ICU) stay, and length of hospital stay were considered as outcome measures. The EuroSCORE (European System for Cardiac Operative Inhibitors,research,lifescience,medical Risk Evaluation) was calculated for all the patients. The EuroSCORE is a risk model which can calculate the risk of death after cardiac

surgery. In this model, 17 different questions (regarding age, sex, arteriopathy, previous surgery, serum creatinine, pulmonary disease, etc.) are asked, and specific software is utilized to calculate the risk via logistic regression. SPSS software version 17

was used for statistical analysis. The continuous variables are reported as Inhibitors,research,lifescience,medical mean±standard deviation or median, and the categorical variables are reported as frequencies and proportions. The Kruskal-Wallis, chi square, and ANOVA tests were employed as appropriate. The effect of seasonal variations on hospital mortality, length Inhibitors,research,lifescience,medical of ICU stay, and length of hospital stay was assessed using multiple logistic regressions in the presence of the EuroSCORE to adjust for the other confounding factors that could affect the outcome of operations. Results Of all the patients who underwent CABG between January 2007 and December 2009 in our centers, only 436 patients had complete archived files to permit the required analysis. Of the 436 patients, 402 received CABG and the remaining 32 patients had CABG combined with some other types of cardiac surgery. The latter group was excluded from Fossariinae the analysis. There were no differences as regards the mean age and the sex ratio of the patients between the four seasons (table 1). Table 1 Characteristics of the patients who underwent coronary artery bypass grafting surgery in various seasons In the mentioned period, only 3 deaths occurred: 2 deaths in spring and one in summer. None of the mortalities occurred in the ICU. No statistical differences could be found between the seasons for the death variable. The mean EuroSCORE was not different between the patients in the four seasons (P=0.

”5 The door to making such informed individual predictions

”5 The door to making such informed individual predictions

was opened when, in the mid 1950s, the link between genetic makeup and drug metabolism was identified6; ie, when it was discovered that the causes for individual variation in drug response could be genetic.7 More precisely, when the extent to which the causes of diverse drug response could be genetic was realized, for the genetic determination of the capacity of an organism to respond to its environment Inhibitors,research,lifescience,medical has long been accepted in biology,8 including the implication of enzymes in the detoxification of foreign substances.9 In addition to nongenetic and environmental causes and Inhibitors,research,lifescience,medical lifestyle factors, eg, age, gender, family- support, good diet, care in following prescriptions, etc, variations in DNA sequence among individuals (genetic polymorphisms) were also found to be involved in the response to drug therapies.10 Accordingly-, knowledge of the individual genome became strongly relevant to drug

prescription.11 Increasing knowledge Inhibitors,research,lifescience,medical of the human genome has given rise to the development of genomic medicine, genetic testing, and also helped in diagnosing some unusual disorders; still, the impact of genetics in medicine during the 20th century was relatively modest.12 The recent development of new technologies for genetic testing has promoted new studies in how drugs and genes interact with potentials for much larger impact.13 Pharmacogenetics (a term coined in the 1950s14) is the study of individual variations in drug response due to heredity. It can be distinguished from phamiacogenomics, a KU-55933 broader term denoting all genes in the genome that may influence drug response, Inhibitors,research,lifescience,medical but the terms Inhibitors,research,lifescience,medical are often used interchangeably.15 There is considerable hope that new and more effective treatments for numerous

mental disorders can result if drugs are developed that specifically target the responsible genes, eg, schizophrenia susceptibility genes.16 If drug prescription can be personalized, ie, tailored to suit the individual’s genetic makeup,17 this holds promise of enormous benefits in terms of, notably, personalized medication with adjusted therapeutic doses, predictable drug responses, reduced ADRs, and personal health planning.18 It should be noted that personalization and individualization, depending on nearly how the concepts are interpreted, need not mean the same thing, and that they are in this context a matter of degree. Here, “personalized medication” can logically, but not realistically, be interpreted as medication developed to suit the singular individual. The realistic interpretation is that personalized medication is “relatively individualized” in the sense of drugs having a more limited group specificity than the earlier “one size fits all” drugs.

0 to 26 1 months Local failure was defined as findings of local

0 to 26.1 months. Local failure was defined as findings of local disease progression on CT or MRI consisting of at least a 20% increase in the sum of the longest diameter of the lesion taking as reference the smallest longest diameter recorded since the treatment started (7). One- and two-year metastasis free survival (MFS) was calculated as defined by the proportion of patients alive without distant metastasis at those

time Inhibitors,research,lifescience,medical points. One- and two-year local control (LC) was calculated as defined by the proportion of patients with no local progression with all other events including death being censored. We calculated OS, MFS, and LC using Kaplan-Meier analysis and used the two-tailed click here log-rank Inhibitors,research,lifescience,medical test to compare survival between the three treatment groups. Time zero was defined as the day of the start of therapy. We repeated the log-rank analysis for the comparison of

C and CCRT excluding patients who died or progressed before three, six, and nine months in order to test whether potential advantages in the CCRT group were due to selection of patients with less aggressive disease. We also calculated OS, MFS, and LC for the subsets of patients with (I) borderline resectable disease and (II) locally advanced disease using Kaplan-Meier analysis and used two-tailed log-rank analysis to compare outcomes for these two groups. Univariable and multivariable survival analyses Inhibitors,research,lifescience,medical were performed using Cox-proportional hazards models. The input variables for multivariable Inhibitors,research,lifescience,medical analysis were those found to be statistically significant on univariable analysis. ANOVA was used to compare means in age and pretreatment CA 19-9 among the treatment

groups. Chi-square was used to test for differences in categorical parameters among the treatment groups. Chi-square was also used to test for differences in patterns of failure. Statistical analyses were conducted using Stata 12.0. This study was approved by an institutional review board. Results Median follow-up was 18.7 months. Twelve of 115 patients were still alive at the time of last follow-up. Inhibitors,research,lifescience,medical There were no statistically significant differences in the baseline characteristics of the treatment groups (Table 1). Fifty-seven patients (49%) had locally advanced disease and 58 patients (51%) had borderline Phosphatidylinositol diacylglycerol-lyase resectable disease and there was no difference in the distribution of treatment strategies between these two groups. There was a trend toward older age and higher CA 19-9 in patients receiving chemotherapy alone. However, there was considerable variation in the CA 19-9. The mean age was 64 years. Surgical resection was ultimately attained in 8/58 (14%) patients with borderline resectable disease and 2/57 (4%) patients with locally advanced disease. Likewise, surgical resection was attained in 6/50 (12%) patients treated with radiation therapy (CRT or CCRT) and 4/65 (6%) of patients treated with chemotherapy alone (C).

To approach the state of the art in diagnosis and treatment of bi

To approach the state of the art in diagnosis and treatment of check details bipolar disorder requires a review of the current state of both research and practice. There is no doubt that bipolar disorder has been an especially important and illustrative field of research in the evolution of psychiatry. Consider the

history of the discovery of lithium. It is a classic example of an alert investigator with both basic science and clinical interests seeing the potential of an unexpected laboratory Inhibitors,research,lifescience,medical observation. Recent diagnostic research, in which controversy abounds regarding under diagnosis and misdiagnosis of bipolar disorder, illustrates the riclmess of the clinical relevance of contemporary diagnostic and nosological research. Other aspects of current research that are relevant to diagnostic validity include genetic and outcome research. With Inhibitors,research,lifescience,medical respect to treatment, there are controversies regarding the use of mood-stabilizing agents, and dilemmas in the use of antidepressant agents in bipolar disorder. In terms of theories of the pathogenesis of bipolar illness, neurobiological research and theories have advanced, with the kindling

hypothesis in particular seeming Inhibitors,research,lifescience,medical useful as a general theory of the pathophysiology of bipolar disorder. In addition, integrative research that includes attention to the psychosocial aspects of bipolar disorder appears on the verge of full development. Progress in scientific psychiatry: the central role of bipolar disorders Bipolar illness, among psychiatric conditions, has served a central role in advancing clinical psychiatry, especially Inhibitors,research,lifescience,medical the interaction of biological predisposition with environmental stress. For one thing, there is a clear genetic diathesis for bipolar illness. Also, there are six different clinical state Inhibitors,research,lifescience,medical changes

that can be studied: two states (depression and mania), and four phase changes (from depression to mania, from mania to depression, from depression to mixed states, and from mixed states to depression). These multiple clinical features of bipolar illness have served as a powerful research tool. And, as noted, there is substantial new bearing on the role of psychosocial factors in the emergence of episodes also of affective illness (eg, the kindling paradigm) and in its treatment as well. Despite the advances that have been made in research into affective illness, such progress is not necessarily smooth and rational. Unfortunately, there is also a tendency toward scientific fads, or “make-believes” according to van Praag.1 It is unfathomable why certain areas of literature simply drop out as others capture our attention and take over. For example, the relatively robust literature on electrolyte disturbances died out rather abruptly in the late 1960s for no apparent reason. Certainly, there was no rash of nonreplications to explain the curious disappearance of this trail.

However, currently it is important to differentiate adenocarcinom

However, currently it is important to differentiate adenocarcinoma with squamous differentiation from pure squamous cell carcinoma

because of the better prognosis of the latter. Pure squamous cell carcinoma of the gallbladder grows slowly, is usually localized and rarely metastasized. On the other hand adenosquamous carcinoma is aggressive and metastasizes widely.1,2 Roa and colleagues studied 606 carcinomas of the gallbladder. Inhibitors,research,lifescience,medical 34 cases showed squamous differentiation and only 1% had pure squamous cell carcinoma. The female/male ratio was 3.8%, similar to adenocarcinoma. The mean age of the BAY 11-7082 solubility dmso patients with squamous cell carcinoma was 65 years and only 13% of patients were suspected for carcinoma preoperatively.1 The etiology and pathogenesis of squamous cell carcinoma is not well understood; however, two important presumptive causative possibilities are gallstones and parasitic infestation.2,3 Another important pathogenetic clue for squamous cell carcinoma is the metaplasia-dysplasia-carcinoma sequence. Most of the cases with squamous cell carcinoma show some Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical degrees of atypical epithelial change adjacent to the invasive tumor.3,4 Gupta and co-workers reported a case of primary squamous cell carcinoma presenting as acute cholecystitis. The patient was operated on after 12 hours and cholecystectomy showed wall thickening with multiple gallstones.5 Other researchers reported

a case of primary squamous cell carcinoma of the gallbladder in an elderly lady with infiltration to the adjacent hepatic parenchyma.6 Rai and colleagues concluded that pure squamous cell carcinoma of the gallbladder was less aggressive than adenocarcinoma. This type of carcinoma should be suspected Inhibitors,research,lifescience,medical when the lesion reaches a large size without metastasis.7 We presented a 70-year-old man diagnosed as having acute cholecystitis based on clinical examinations and ultrasonographic findings. The patient lacked general signs of malignancy such as weight loss or apparent jaundice. He was completely

asymptomatic except for the presentation of acute cholecystitis. In our case the subtle Inhibitors,research,lifescience,medical clinical presentation could be in favor of the less aggressive behavior of pure squamous cell carcinoma of the gallbladder in comparison with adenocarcinoma or adenosquamous variants, which was reported in some previous studies. Conclusion Pure primary squamous cell carcinoma of the gallbladder is rarely reported. Clinicians and pathologists must be aware of its vague clinical presentations. Conflict of Interest: None also declared
Background: It seems that the incidence of pertussis-like illnesses is considerably increasing despite the wide coverage of immunization with the whole cell pertussis vaccine. We aimed to investigate the occurrence of pertussis in vaccinated children by measuring anti-pertussis antibodies. Methods: In this cross-sectional study, blood samples were taken from vaccinated children aged 2, 4, 6, 12, 18, and 72 months.

The incredible contributions of Pick, Langendorf, and Katz deserv

The incredible contributions of Pick, Langendorf, and Katz deserve

mention.17–19 They undertook detailed and painstaking analyses of literally thousands of strips from patients with the WPW syndrome and concluded that the arrhythmias were due to differences in conduction properties between the AV node and the AP, which allowed for initiation of SVT by premature beats. Remarkably they described concealed conduction into the pathway and the find more relationship between SVT and AF for these patients. Much of their pioneering observations were substantiated by intracardiac studies. Drs Durrer and Wellens20,21 were the first to systematically use programmed electrical studies in Inhibitors,research,lifescience,medical numbers to clearly define the tachycardia mechanisms in patients with WPW. They showed that premature cardiac stimulation could induce orthodromic (SVT) (antegrade conduction over the AV node, retrograde conduction over the AP) as

well as antidromic tachycardias (antegrade conduction over the AP, retrograde conduction over the node). These Inhibitors,research,lifescience,medical observations and others22,23 provided Inhibitors,research,lifescience,medical the framework for the use of intracardiac studies to define AP location and physiology. SURGICAL CONTRIBUTIONS Prior to the current era of catheter ablation, patients with SVT intractable to drug therapy were treated with surgical dissection of the AV junction.24,25 This approach was largely used for management of the patient with atrial fibrillation refractory Inhibitors,research,lifescience,medical to drug therapy but would not be appropriate for those with

APs since extirpation of the AV junction would not mitigate against rapid conduction over an AP. Durrer and Roos26 performed intraoperative mapping and cooling (in an important proof of concept experiment) to locate and transiently prevent conduction in a patient with a right-sided AP. Subsequently Burchell et al.27 used intraoperative mapping and abolished pre-excitation with a local injection of procainamide. Inhibitors,research,lifescience,medical A limited surgical incision over this area resulted in only transient loss of pre-excitation. Sealy et al.28 were the first to successfully ablate an AP in a human. The Duke team initially used an epicardial approach but subsequently showed that APs in all locations (both free wall and septal) could why be successfully ablated using an endocardial technique.29 Only later was a cryo-epicardial technique used by Guiraudon et al.30 CATHETER ABLATION The technique of catheter ablation of the AV junction was introduced by Scheinman et al. in 1981.31 The technique involved use of high-energy direct-current shocks delivered to the region of the AV junction. This was followed by attempts to use catheter techniques for ablation of APs in various locations. In 1984 Fisher et al.32 used this technique for attempted ablation of left-sided APs via the coronary sinus. This technique was abandoned due to limited efficacy and risk of cardiac tamponade.

Color flow is used to identify flow in the target artery; then, using gray scale, the needle is used to access the anterior wall of the vessel under duplex guidance.

There are a couple of technical points worth mentioning when using this technique. Use of the smallest available ultrasound probe is recommended as the large ones are quite bulky and will interfere with the access process. Also, heavily calcified vessels can cause extensive shadowing that will make the technique difficult. In these situations, straight fluoroscopy or roadmapping may offer a better chance for successful access. Also, use of micropuncture needles that are purported to be echogenic is recommended as it is difficult to see Inhibitors,research,lifescience,medical the tip of the regular needles using the duplex ultrasound probe. Figure 2. Duplex ultrasound-guided access into the dorsalis pedis artery. (A) Duplex ultrasound probe and 21-gauge needle in place. (B) Color duplex identifies the patent anterior tibial artery lumen. (C) Tip of the needle inside the vessel on ultrasound (red arrow). Inhibitors,research,lifescience,medical … The position of the foot during the access procedure is important. We recommend placing the foot in plantar flexion when accessing the dorsalis pedis and anterior tibial artery and inverting the foot when accessing the distal peroneal

artery in the leg, which is not a vessel that Inhibitors,research,lifescience,medical is typically accessed. We also prefer eversion and dorsiflexion when accessing the posterior tibial artery in the distal leg. Choosing the site of Inhibitors,research,lifescience,medical vessel access is important to achieve success,

and it is usually an area that is patent and as healthy as possible. A micropuncture needle is used for access. Sometimes Ganetespib purchase bending the needle tip rather than keeping the needle straight can make easier it to access the vessel. This is particularly helpful if the point of access is in the anterior tibial artery, Inhibitors,research,lifescience,medical just above the ankle, or in the posterior tibial artery. After accessing the artery (as evidenced by back bleeding), the micropuncture access wire (0.018 in) is passed through the needle into the vessel under fluoroscopic guidance (Figure 3). The needle is removed, and a micropuncture 4-Fr sheath is passed over the wire, securing access. Sometimes we use only the dilator of the sheath without the sheath itself to secure access (Figure 4). Cook Medical Inc. (Bloomington, IN) has a commercially available dedicated pedal access kit. The kit includes a 21-gauge, 4-cm echogenic needle; a 7-cm long micropuncture 4-Fr introducer with a 2.9-Fr found inner diameter; and a Check-Flo® hemostasis valve that attaches directly to the introducer to inject fluids and contrast (Figure 5). Once the retrograde introducer is in place, the patient is fully heparinized in the usual fashion to avoid any thrombosis in the tibial vessels during the intervention. Some operators elect to use the 0.018-in wire in a sheathless manner to reduce the risk of disrupting the access vessel—the dorsalis pedis or distal tibial arteries.

EGFR missense and deletion mutations were found in 13 4% of non-s

EGFR missense and deletion mutations were found in 13.4% of non-small cell lung cancer (NSCLC) patients, within exons 18 through 21 of the kinase domain (4). Lynch et al. reported in-frame deletions and amino acid substitutions, clustered in the region of the ATP-binding pocket of the TK domain, in eight of nine patients with gefitinib-responsive NSCLC (5). While EGFR mutations are characteristic Inhibitors,research,lifescience,medical for NSCLC, PIK3CA mutations are also identified in glioblastomas, colorectal cancer, gastric cancer, and breast cancer (3,6). EGFR is expressed by many epithelial tumor cells, including biliary and pancreatic cancers (7-9). Inhibition of activated

protein kinases through the use of targeted small molecule drugs (i.e., Inhibitors,research,lifescience,medical gefitinib and erlotinib) or COX inhibitors library antibody-based (i.e., cetuximab and panitumumab) strategies have emerged as an effective approach to cancer therapy (10-12). EGFR expression itself is not a definite predictor of response to EGFR TK inhibitors (13), however, EGFR mutations in NSCLC were found to predict sensitivity to gefitinib (4). Phase II studies have shown that TK inhibitors (TKI) induced response in over 70% of NSCLC patients harboring EGFR mutations (14). Both pancreatic and biliary tract carcinoma Inhibitors,research,lifescience,medical are diagnosed at advanced stages when

incurable, Inhibitors,research,lifescience,medical and outcomes even with surgery and chemotherapy, are poor (15-19). Combination of erlotinib

and gemcitabine in advanced pancreatic cancer showed a modest increase in survival compared to gemcitabine alone, and resulted in the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMEA) approval for this regimen as first-line treatment Inhibitors,research,lifescience,medical of pancreatic cancer (20). The objectives of this study were to determine the prevalence of EGFR and PI3K mutations in patients with pancreaticobiliary cancers. No studies had been reported at the time our research began of either EGFR or PIK3CA mutations in either disease. Several small reports have been published since, and this article will next summarize the current literature in this field. Materials and methods Study population This study was performed with approval of the Roswell Park Cancer Institute (RPCI) Institutional Review Board. The institutional pathology department reviewed all cases of pancreatic and biliary tract cancers following pancreatectomy diagnosed at RPCI over a period of five years between December 1, 1999, and November 30, 2004. All tumor blocks with adequate DNA for performing mutation analysis were selected for inclusion. Clinical data, including age, sex, ethnicity, and clinical stage, was obtained via chart review unblinded to mutation results. The samples were numbered consecutively to ensure patient confidentiality.

Telomerase reverse transcriptase (TERT) is an enzyme required for

Telomerase reverse transcriptase (TERT) is an enzyme required for the proliferative capacity and survival of cells. It is an RNA-dependent DNA polymerase responsible for de novo elongation of telomere repeats at the chromosome termini, by adding telomeric repeats to the 3’ end of the telomeric strand, through copying of the selleck compound template sequence present in Inhibitors,research,lifescience,medical its RNA moiety (21, 22). Low level of telomerase activity has been discovered in mitotically active cells, including skin, lymphocytes, and endometrium and stem cells (23). In the present study we find significantly decreased levels in telomerase activity among DMD patients compared to controls. Evidence support that, a correlation

Inhibitors,research,lifescience,medical is observed between the level of induced telomerase activity and change in telomere length, such that telomere lengthening rather than telomere loss was found in cells when telomerase activity reached relatively high levels; conversely, telomere loss was evident when telomerase activity was low (24). The decrease in telomerase activity observed in DMD

patients compared to controls can be attributed to the fact that increased oxidative stress induces a decrease Inhibitors,research,lifescience,medical in telomerase activity (25). Bax genes expresses a Bax, a pro-apoptotic Bcl-2 family member, can heterodimerize with either Bcl-2 or Bcl-xL to nullify their anti-apoptotic properties (26). Increased Bax mRNA expression has been observed in ageing human lymphocytes (27, 28). Exercise loading caused an increased expression in Bax localization in muscular dystrophy animal model (29). Meaning that oxidative stress due to exercise in DMD brings damage similar to that observed in aging, which coincide with our results. An aging hypothesis states that aged tissues are Inhibitors,research,lifescience,medical characterized by the accumulation of a variety of types of advanced glycation end products (AGEs), which are the products of nonenzymatic glycation and oxidation of proteins and lipids and DNA (30, 31). RAGE is a multiligand receptor

of the immunoglobulin superfamily expressed in almost all body cells including endothelial cells, Inhibitors,research,lifescience,medical monocytes, neutrophils, myoblasts and vascular smooth muscle cells (32). RAGE has been identified as receptor, which binds β-sheet fibrils characteristic of amyloid; proinflammatory cytokine-like mediators of the S100/calgranulin out family. Engagement of RAGE by these ligands activates key signal transduction pathways, such as p21ras, erk 1/2 kinases and nuclear factor-κB in endothelial cells, monocytes, and vascular smooth muscle cells (33). This cascade of events leads to RAGE-mediated-enhanced expression of proinflammatory mediators. Evidence support that RAGE mediate the effects of AGEs by both ligand engagement and signal transduction (34). There was a significant increase in RAGEs mRNA expression in peripheral blood mononuclear cells of DMD compared to controls.

In order to identify an appropriate drug combination, it is neces

In order to identify an appropriate drug combination, it is necessary to perform thorough biological evaluation which must be supported by a profound understanding of the molecular mechanisms involved. Another critical aspect is the determination of the optimal mass ratio of each component within a combination drug delivery system. This requires systematic research investigating

the impact of different drug ratios on the biological activity of the combination Inhibitors,research,lifescience,medical delivery systems. Recently a Canadian pharmaceutical company Celator (http://www.celator.ca/) has developed a methodical approach to assess different drug ratios within their liposomal technology resulting in the development of different liposomal formulations that are now Inhibitors,research,lifescience,medical being assessed in phase II clinical trials, namely, CPX-1 (irinotecan: floxuridine) and CPX-351 (cytarabine: daunorubicin). Such an approach needs to be extended to other combination delivery systems such as dendrimers or polymer-drug conjugates. Determination of the kinetics of

release of each drug in a multidrug combination system will be also necessary to determine the optimum ratio as one drug may affect the release profile of the other drug and thereby affect activity. Finally clinical development of these combination products is extremely challenging, due to developmental costs of designing such complex systems. However, these combination drug delivery system-based therapeutics Inhibitors,research,lifescience,medical are likely to be perceived by pharmaceutical companies as novel opportunities to extend the patent lives compared Inhibitors,research,lifescience,medical to current blockbuster drugs.
Controlled-release multiunit dosage forms (e.g., pellets, granules, or microparticles) are becoming

more and more important on the pharmaceutical market, as they provide several advantages compared to single-unit dosage forms (e.g., tablets or capsules) [1]. With regard to the final dosage form, the multiunits can be filled into hard gelatin capsules [2] or be compressed into disintegrating tablets [3, 4]. The advantages of tableting multiunits Inhibitors,research,lifescience,medical Akt inhibitor include less difficulty in oesophageal transport, and thus a better patient compliance. Tablets can be prepared at a lower cost because of the higher production rate of tabletting process. The expensive control of capsules PD184352 (CI-1040) integrity after filling is also eliminated. In addition, tablets containing multiunits could be scored without losing the controlled release properties, which allows a more flexible dosing regimen [5]. One challenge in the production of such systems is maintaining the desired drug release after compaction as the application of compaction pressure can lead to structural changes in the film coating and consequently altered drug release [6]. The compression-induced changes in the structure of a film coating may depend on formulation factors such as mechanical properties of the film and incorporated excipients of pellets [7].
