The Effect of HLB on the Release Profile of Atenolol from Ethyl Cellulose-coated Tablets
It is possible to alter the permeability of ethyl cellulose membrane with certain materials such as surfactants. In this study the effect of surfactant concentration and different HLB values on the release rate of atenolol from ethyl cellulose-coated tablets was evaluated. The results showed that when the concentration of surfactant increased, the rate of drug release also increased. The kineti...

متن کاملDesign and Evaluation of Delayed-Release Osmotic Capsule of Acetaminophen
Hard gelatin capsule filled with acetaminophen, osmotic agent (sorbitol), a release promoter (sodium dodecyl sulfate), coated with a semipermeable cellulose acetate membrane containing a hydrophobic plasticizer (castor oil) and sealed with white bees wax plug was designed. When placed in the sink water penetrates the membrane, dissolves the osmotic agent and increases the osmotic pressure...
متن کاملTimed-Release Cryptography
Let n be a large composite number. Without factoring n, the computation of a t (mod n) given a, t with gcd(a; n) = 1 and t < n can be done in t squarings modulo n. For t n (e.g., n > 2 and t < 2), no lower complexity than t squarings is known to ful ll this task. Rivest et al suggested to use such constructions as good candidates for realising timed-release crypto problems. We argue the necessi...
متن کاملDevelopment and evaluation of regioselective bilayer floating tablets of Atenolol and Lovastatin for biphasic release profile
This study was performed to design bilayer regioselective floating tablets of atenolol and lovastatin to give immediate release of lovastatin and sustained release of atenolol. Bilayer floating tablets comprised two layers, i.e immediate release and controlled release layers. The immediate release layer comprised sodium starch glycollate as a super disintegrant and the sustained release layer c...
