IVIVC for Extended-Release Hydrophilic Matrix Tablets in Consideration of Bio...
Purpose
When establishing IVIVC, a special problem arises by interpretation of averaged in vivo profiles insight of considerable individual variations in term of time and number of mechanical stress events in GI-tract. The objective of the study was to investigate and forecast the effect of mechanical stress on in vivo behavior in human of hydrophilic matrix tablets.
Methods
Dissolution profiles for the marketed products were obtained at different conditions (stirring speed, single- or repeatable mechanical stress applied) and convoluted into C-t profiles. Vice versa, published in vivo C-t profiles of the products were deconvoluted into absorption profiles and compared with dissolution profiles by similarity factor.
Results
Investigated hydrophilic matrix tablets varied in term of their resistance against hydrodynamic stress or single stress during the dissolution. Different scenarios, including repeatable mechanical stress, were investigated on mostly prone Seroquel® XR 50 mg. None of the particular scenarios fits to the published in vivo C-t profile of Seroquel® XR 50 mg representing, however, the average of individual profiles related to scenarios differing by number, frequency and time of contraction stress. When different scenarios were combined in different proportions, the profiles became closer to the original in vivo profile including a burst between 4 and 5 h, probably, due to stress-events in GI-tract.
Conclusion
For establishing IVIVC of oral dosage forms susceptible mechanical stress, a comparison of the deconvoluted individual in vivo profiles with in vitro profiles of different dissolution scenarios can be recommended.
Wurster Fluidised Bed Coating of Microparticles: Towards Scalable Production ...
Suspension of microparticles in an easy-to-swallow liquid is one approach to develop sustained-release formulations for children and patients with swallowing difficulties. However, to date production of sustained-release microparticles at the industrial scale has proven to be challenging. The aim of this investigation was to develop an innovative concept in coating sustained-release microparticles using industrial scalable Wurster fluidised bed to produce oral liquid suspensions. Microcrystalline cellulose cores (particle size <150 μm) were coated with Eudragit® NM 30 D and Eudragit® RS/RL 30 D aqueous dispersions using a fluidised bed coater. A novel approach of periodic addition of a small quantity (0.1% w/w) of dry powder glidant, magnesium stearate, to the coating chamber via an external port was applied throughout the coating process. This method significantly increased coating production yield from less than 50% to up to 99% compared to conventional coating
process without the dry powder glidant. Powder rheology tests showed that dry powder glidants increased the tapped density and decreased the cohesive index of coated microparticles. Reproducible microencapsulation of a highly water-soluble drug, metoprolol succinate, was achieved, yielding coated microparticles less than 200 μm in size with 20-h sustained drug release, suitable for use in liquid suspensions. The robust, scalable technology presented in this study offers an important solution to the long-standing challenges of formulating sustained-release dosage forms suitable for children and older people with swallowing difficulties.

Purpose
Fluid-bed coating of microparticles using aqueous polymer dispersions is a challenge due to particle agglomeration. Agglomeration is an undesirable phenomenon especially for modified release products resulting in inconsistent and unreliable coating thickness and drug release profile. Due to the small particle size and relatively high coating level, the determination of agglomerated particles is complicated and cannot be performed by common methods such as sieve analysis and observation under light microscope.
The objective of this study was to investigate appropriate methods to determine the internal structure of coated microparticles to support decision making in the formulation and coating process development.

Purpose
Most oral dosage forms such as tablets and capsules are not suitable for older people with swallowing difficulties. Capsules opening and tablet crushing are commonly used to overcome this problem. In addition to safety and legal concerns, this approach cannot be applied to sustained release products because of the loss of their functionality, consequently causing dose dumping and, undesirable side effects and even toxicity. The number of appropriate medicines for older patients with swallowing difficulties is limited because of the absence of appropriate oral dosage forms. One of the most appropriate forms of medicines for patients with swallowing difficulties are liquid formulations.
To overcome the described issues in older patients with dysphagia, the present study aimed at the development of film-coated sustained release microparticles for use in redispersible multi-dose oral suspensions to ensure facilitated swallowing and acceptable shelf life.

The present study was aimed at the development of a redispersible multi-dose suspension based on coated microparticles to ensure easy swallowing and sustained release of metoprolol succinate. To provide sustained release of metoprolol succinate, the microparticles were prepared by drug loading and Eudragit NM coating in a fluid-bed coater. Compositions of the liquid suspension vehicle were selected to reduce solubility of metoprolol succinate. The effect of vehicle composition and suspension storage time at RT on drug leaching into the suspension vehicle and on the drug release profile were investigated. The approach allowed a redispersible multi-dose suspension of metoprolol microparticles which, after one month storage, displayed negligible drug leaching into the suspension vehicle and a sustained release profile comparable to the profile before storage.

A thesis for the Candidate of Pharmacy Degree in specialty 15.00.01. – Technology of drugs, organization of pharmaceutical business and forensic pharmacy. – Shupyk National Medical Academy of Postgraduate Education, Kyiv, 2016.
Dissertation is dedicated to the study of factors affecting the release kinetics of freely soluble active pharmaceutical ingredient trimetazidine dihydrochloride (TMZ•2HCl) in vitro from matrix tablets produced using direct compression method.
Effect of soluble matrix formers on TMZ•2HCl release profile from matrix tablets was conducted. It was experimentally established that matrix former release prolongation possibility increased with increasing of possibility to form viscous solutions in water: Klucel HXF > Methocel K15M > Polyox WSR-301 > Kollidon K-90 for different polymers and Methocel K100M > K15M > K100LV for same polymers with different molecular weight. Slowdown of release in the release medium with pH 6.8 was due to the interaction of TMZ•2HCl and Carbopol 71G with rubber-like layer formation.
It was experimentally established that effect of insoluble matrix formers on TMZ•2HCl release profile from matrix tablets was in sequence: Ethocel 10 > Precirol ATO 5 ≈ Kollidon SR > Eudragit RSPO. Swelling of Kollidon SR matrix was due to elastic recovery of spherical shape of polymer particles and polyvinyl acetate swelling upon hydration.
Diluents type effect on TMZ•2HCl dissolution profile was investigated. Soluble (sorbitol), insoluble (calcium hydrogen phosphate dihydrate), insoluble and swellable (cellulose microcrystalline) diluents were used. Faster TMZ•2HCl release from Ethocel 10, Kollidon SR and Methocel K4M matrix tablets with sorbitol than Emcompress and Avicel PH-101 was established. During determination of Emcompress and Avicel PH-101 effect on release kinetics from matrix tablets with different matrix formers were established that release was faster using: Avicel PH-101 in insoluble unswellable matrix of Ethocel 10; Emcompress in insoluble swellable matrix of Kollidon SR; Avicel PH-101 in soluble swellable matrix of Methocel K4М. It was established that TMZ•2HCl release kinetics from matrix tablets with Ethocel 10, Kollidon SR and Methocel K4M and Emcompress diluent was higher in pH 1 medium than in pH 6.8 which is consistent with pH-dependent Emcompress solubility.
Soluble diluents particle size effect on TMZ•2HCl dissolution profile was also investigated. Decreasing of TMZ•2HCl dissolution kinetics from Ethocel 10 matrix tablets with lactose and sorbitol particle size increasing was established. The dissolution kinetics from Kollidon

Abstract:
An increasing number of active compounds in pipelines today have properties that require functional formulation to enable exposure and efficacy. Despite many new technology choices, it is often difficult to match the right drug-delivery technology to a given molecule and problem statement. This problem is exacerbated by the need to save time and valuable drug in early development. This webinar describes an efficient strategy for mating enabling drug-delivery technologies with problem statements based on challenging compound properties and product concepts, building on an understanding of gut physiology, key molecule physicochemical properties, and the target product profile.

Spray coatings of ethylcellulose for sustained drug release on multi-particulate dosage forms is common in the pharmaceutical industry, but can be disadvantageous because of long process times, need for organic solvent capabilities, and particulate agglomeration.
Using a rotor process technology, ethylcellulose can be applied to drug layered beads as a dry powder; enabling the user to achieve high levels of weight gain in a short period of time while still demonstrating sustained release.
Information will be presented comparing performance and productivity to traditional solvent-based Wurster coating and aqueous-based Wurster coating.

Примечание автора: Рис. 4 А и Рис 4 В перепутаны местами
Термин «пеллета» используется в различных отраслях промышленности и несет различную смысловую нагрузку. В фармацевтической промышленности пеллетами называют сыпучие сферообразные частицы, произведенные посредством агломерации тонких порошков или гранул с использованием соответствующего процессного оборудования. Этот термин был введен в 70-х годах прошлого столетия в фармацевтической промышленности в контексте мультипартикулярных систем доставки, которые имеют ряд преимуществ перед монопартикулярными. Данная тема раскрывалась на страницах нашего журнала ранее.

2014.09.30. Bioavailability Enhancement Webinar Series: Optimizing Technology Choice to Enhance Bioavailability
Capsugel (Bend Research)
Abstract:
An increasing number of active compounds in pipelines today have properties that require functional formulation to enable exposure and efficacy. Despite many new technology choices, it is often difficult to match the right drug-delivery technology to a given molecule and problem statement. This problem is exacerbated by the need to save time and valuable drug in early development. This webinar describes an efficient strategy for mating enabling drug-delivery technologies with problem statements based on challenging compound properties and product concepts, building on an understanding of gut physiology, key molecule physicochemical properties, and the target product profile.

2016.08.15. rotor powder coating using ethocel ph (dow colorcon)
Spray coatings of ethylcellulose for sustained drug release on multi-particulate dosage forms is common in the pharmaceutical industry, but can be disadvantageous because of long process times, need for organic solvent capabilities, and particulate agglomeration.
Using a rotor process technology, ethylcellulose can be applied to drug layered beads as a dry powder; enabling the user to achieve high levels of weight gain in a short period of time while still demonstrating sustained release.
Information will be presented comparing performance and productivity to traditional solvent-based Wurster coating and aqueous-based Wurster coating.

Примечание автора: Рис. 4 А и Рис 4 В перепутаны местами
Термин «пеллета» используется в различных отраслях промышленности и несет различную смысловую нагрузку. В фармацевтической промышленности пеллетами называют сыпучие сферообразные частицы, произведенные посредством агломерации тонких порошков или гранул с использованием соответствующего процессного оборудования. Этот термин был введен в 70-х годах прошлого столетия в фармацевтической промышленности в контексте мультипартикулярных систем доставки, которые имеют ряд преимуществ перед монопартикулярными. Данная тема раскрывалась на страницах нашего журнала ранее.

Alcohol_Dr. Jeenal Mistry MD Pharmacology.pdf
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
