The effects of poly(vinylpyrrolidone) (PVP) molecular weight, composition, and content on the crystallization of a model drug, MK-0591, were investigated. 
Solid dispersions of crystalline MK-0591 with PVP homopolymers of different molecular weights (2500-1 x 10(6) g/mol) and with a copolymer containing poly(vinyl acetate) (PVA), (PVP/VA, 60:40, 5.8 x 10(4) g/mol) were prepared by the solvent method. 
MK-0591 in the solid dispersions was found to be X-ray amorphous. 
One glass transition temperature (T(g)) was observed suggesting drug-polymer miscibility. 
The T(g) values were higher than predicted by the Gordon-Taylor equation, indicating drug-polymer interactions. 
The extent of crystallization inhibition increased with PVP molecular weight and, for a comparable PVP molecular weight, the homopolymer was more effective in the crystallization inhibition of the drug than the copolymer. 
The first onset temperature of crystallization (T(c)(obs)) increased with polymer content. 
The T(c)(obs) values (normalized to polymer content) were a function of the difference between the T(g) of the polymer and drug. For PVP K-90, K-30, and K-17 dispersions, the T(c)(obs) values increased proportionally to the T(g) of the dispersions. 
However, for PVP K-12 and PVP/VA, the increase in T(c)(obs) values corresponded to a small decrease in the T(g) values of the dispersions. 
This result suggests that additional factors other than the reduction in mobility affect the crystallization behavior of MK-0591 in the solid dispersions, such as specific interactions. 
By Fourier transform-infrared spectroscopy, changes in the carbonyl-stretching band of PVP in the solid dispersions were observed. 
The existence of an ion-dipole interaction between COO(-)Na(+) of the drug and the cyclic amide group of PVP was postulated.

PVP K 12, also commonly called polyvidone or povidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone.
PVP was used as a plasma volume expander for trauma victims after the 1950s. 
PVP K 12 is not preferred as volume expander due to its ability to provoke histamine release and also interfere with blood grouping.
PVP K 12 is used as a binder in many pharmaceutical tablets; it simply passes through the body when taken orally. 
(However, autopsies have found that crospovidone (PVPP) contributes to pulmonary vascular injury in substance abusers who have injected pharmaceutical tablets intended for oral consumption.
The long-term effects of crospovidone or povidone within the lung are unknown).
PVP added to iodine forms a complex called povidone-iodine that possesses disinfectant properties.
PVP K 12 is used in various products like solutions, ointment, pessaries, liquid soaps and surgical scrubs. 
PVP K 12 is known under the trade names Pyodine and Betadine, among a plethora of others.
PVP K 12 is used in pleurodesis (fusion of the pleura because of incessant pleural effusions). 
For this purpose, povidone iodine is equally effective and safe as talc, and may be preferred because of easy availability and low cost.
PVP is used in some contact lenses and their packaging solutions. 
PVP K 12 reduces friction, thus acting as a lubricant, or wetting agent, built into the lens. 
Examples of PVP K 12 use include Bausch & Lomb's Ultra contact lenses with MoistureSeal Technology and Air Optix contact lens packaging solution (as an ingredient called "copolymer 845").

Other uses of PVP K 12
PVP binds to polar molecules exceptionally well, owing to its polarity. 
PVP K 12 has led to its application in coatings for photo-quality ink-jet papers and transparencies, as well as in inks for inkjet printers.
PVP is also used in personal care products, such as shampoos and toothpastes, in paints, and adhesives that must be moistened, such as old-style postage stamps and envelopes. 
PVP K 12 has also been used in contact lens solutions and in steel-quenching solutions.
PVP is the basis of the early formulas for hair sprays and hair gels, and still continues to be a component of some.
As a food additive, PVP is a stabilizer and has E number E1201. 
PVPP (crospovidone) is E1202. 
PVP K 12 is also used in the wine industry as a fining agent for white wine and some beers.
In molecular biology, PVP can be used as a blocking agent during Southern blot analysis as a component of Denhardt's buffer. 
PVP K 12 is also exceptionally good at absorbing polyphenols during DNA purification. 
Polyphenols are common in many plant tissues and can deactivate proteins if not removed and therefore inhibit many downstream reactions like PCR.
In microscopy, PVP K 12 is useful for making an aqueous mounting medium.
PVP K 12 can be used to screen for phenolic properties, as referenced in a 2000 study on the effect of plant extracts on insulin production.

Micromechanical properties of PVP K 12 interparticle bridges formed by different polymeric binder differ on their viscosity. 
RCDG gave poor results as very fine and inconsistent particle size with PVP K 12 and HPC SSL. 
PVP K 12 may cause of elastic deformation of acetaminophen which produced poor compact even after two roll compaction. 

Safety of PVP K 12
The U.S. Food and Drug Administration (FDA) has approved this chemical for many uses, and it is generally considered safe. 
However, there have been documented cases of allergic reactions to PVP/povidone, particularly regarding subcutaneous (applied under the skin) use and situations where the PVP has come in contact with autologous serum (internal blood fluids) and mucous membranes.
For example, a boy having an anaphylactic response after application of PVP-Iodine for treatment of impetigo was found to be allergic to the PVP component of the solution.
A woman, who had previously experienced urticaria (hives) from various hair products, later found to contain PVP, had an anaphylactic response after povidone-iodine solution was applied internally. 
She was found to be allergic to PVP. 
In another case, a man experiencing anaphylaxis after taking acetaminophen tablets orally was found to be allergic to PVP.
Povidone is commonly used in conjunction with other chemicals. 
Some of these, such as iodine, are blamed for allergic responses, although testing results in some patients show no signs of allergy to the suspect chemical. 
Allergies attributed to these other chemicals may possibly be caused by the PVP instead.

Properties of PVP K 12
PVP K 12 is soluble in water and other polar solvents. 
For example, PVP K 12 is soluble in various alcohols, such as methanol and ethanol, as well as in more exotic solvents like the deep eutectic solvent formed by choline chloride and urea (Relin).
When dry PVP K 12 is a light flaky hygroscopic powder, readily absorbing up to 40% of its weight in atmospheric water. 
In solution, PVP K 12 has excellent wetting properties and readily forms films. 
PVP K 12 makes it good as a coating or an additive to coatings.
A 2014 study found fluorescent properties of PVP and its oxidized hydrolyzate.

PVP K 12, a kind of non-ionic polymer, is one of the most characteristic and most widely studied fine chemical in N- vinyl amide polymer.
The K value of PVP is actually the characteristic value related to the relative viscosity of PVP aqueous solution, and the viscosity is the physical quantity related to the molecular weight of polymer, so the K value can be used to characterize the average molecular weight of PVP. 
The larger the K value is, the greater the viscosity is, the stronger the adhesion.
PVP K 12 is a synthetic water-soluble polymer compound, has the general properties of water soluble polymer, colloid protection, film, adhesion, solubility or aggregation, but the most characteristic is the excellent solubility and biocompatibility. 
In the synthesis of polymer like PVP is soluble in water, but soluble in most organic solvents, low toxicity, good physiological compatibility is rare, especially in medicine, food, cosmetics, which is closely related to people's health in the field, with the raw material prices lower butyrolactone, will show a good the prospect of its development.
Many people confuse about the K value of PVP and the corresponding molecular weight, so here is the K value of each model and its molecular weight of PVP:

Molecular Weight of PVP K series:
PVP K12: 3000-7000
PVP K15: 8000-12000
PVP K17: 10000-16000
PVP K25: 30000-40000
PVP K30: 45000-58000

Five varieties of Poly Vinyl Pyrrolidone i.e., PVP K-12, PVP K-17, PVP K-25, PVP K-30 and PVP K-90 were studied in this investigation. 
The drug polymer ratios in these formulations were ranged from 1:1, 1:2, 1:4 and 1:6. 
The solid dispersions were prepared by microwave fusion method and compressed by tablet punching machine. 
The prepared tablets were evaluated for physicochemical properties and dug release characteristics. 
The drug release was further analyzed kinetically with first order and Hixson Crowell’s plots. 
All the batches of tablets were shown good release characteristics and among the Poly Vinyl Pyrrolidone polymers, PVP K-17 was found to be good as a carrier for increasing the solubility and Release rate from the solid dispersions of Etoricoxib.

The results showed that the MADG and HME technique using maltodextrin, PVP K 12 and HPC as “polymeric-binders” enabled to obtain desirable granules, while the use of RCDG/PVP and RCDG/ HPC gave poor result in granules preparation.
MADG/Maltodextrin and HME HME /Malltodextrin provided granules with a more irregular and porous surface area than other granules, as observed by SEM. 
These characteristics reflected on the dissolution behaviour, showing that granules prepared with Maltodextrin/MADG and Malltodextrin/HME methods increases the dissolution rate of acetaminophen, followed by granules prepared with PVP, HPC in all three granulation methods. 
In conclusion, the findings of this work showed that MADG and HME methods of granulation could be very successful industry feasible methods to improve the dissolution rate of a poorly soluble drug as
Acetaminophen, when associated with maltodextrin as binder. 
These methods, minimizes the total number of excipients thus decreasing the complexity of the formulation and increasing the scalability of the formulation.
