Methyl cellulose (MC) and hydroxypropyl methyl cellulose (HPMC) were found very effective in preventing growth of crystals and improving the dissolution of aceclofenac.
Most of the commonly used polymer excipients in this category are hydroxypropyl methyl cellulose (HPMC), methyl cellulose (MC), sodium carboxymethyl cellulose (NaCMC) and polyvinyl pyrrolidone (PVP).
Films were prepared comprising polymeric excipients such as chitosan, (hydroxypropyl)methyl cellulose, hydroxyethyl-cellulose, carboxymethylcellulose according to solvent evaporation method.
Sustained release matrix tablets of various combinations were prepared with cellulose-based polymers: hydroxy propyl methyl cellulose (HPMC) and polyvinyl pyrolidine (pvp) and lactose as fillers.
The poloxamer 407, methyl cellulose, hydroxypropyl methyl cellulose and polyethylene glycol were used alone and in combination in different ratios to design the delivery system.
For conventional methods the thickeners are such reagents as starch, gum tragacanth, alginates, methyl cellulose ethers, and sodium carboxymethyl cellulose.
The most widely used mud thickeners are carboxy methyl cellulose (CMC) and hydroxy ethyl cellulose (HEC) (Rabia 1985).
After 24 h, cells were trypsinized, pelleted, and resuspended in 300uL of medium which was then combined with 2.7 mL of methyl cellulose growth medium [2.6% methyl cellulose, (Shin-Etsu) and 30% FBS in IMDM (Princess Margaret Hospital)].
One-hundred-nm-thin sections were cut on a Leica UC6 equipped with a FC6 cryo-chamber and picked up in methyl cellulose sucrose (1 part 2% (w/v) methyl cellulose (Sigma M-6385, 25 centipoises) + 1 part 2.3 M sucrose).
Grids were floated on a drop of 2% methyl cellulose (in water) for 5 min, picked up with a loop and excess methyl cellulose was removed with a Whatman #1 filter paper to form an even layer of methyl cellulose over the grid (to avoid drying artifacts).
