Cervicofacial hemangiomas treated from January 2001 to December 2009 was clinically evaluated. This retrospective clinical study consisted of 42 females and 20 males with the age ranged from 20 days to 55 years. The lesions were present with-in first month in 45 patients (72.6%). Two patterns of tumor growth were evident: focal and diffuse. There were 59 focal hemangiomas (80.8%) and 14 diffuse...

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...

This study was performed to design bilayer floating tablets of simvastatin and lovastatin to give sustained release of simvastatin and immediate release of lovastatin. Bilayer floating tablets comprised of two layers i.e, immediate and sustained release layers. Bilayer floating tablets of simvastatin and lovastatin was formulated by using HPMCK 100M and super disintegrants like sodium alginate,...

the purpose of this review article is to characterize all of the parameters regarding the types, polymers used, and release kinetics of matrix tablets. matrix system was the earliest oral extended release platform for medicinal use. matrix tablets are most commonly used methods to modulate the release profile of drugs. they are much desirable and preferred for such therapy because they offer be...

The purpose of this study is to evaluate the in vitro and in vivo performance of gastro-retentive matrix tablets having Metformin HCl as model drug and combination of natural polymers. A total of 16 formulations were prepared by a wet granulation method using xanthan, tamarind seed powder, tamarind kernel powder and salep as the gel-forming agents and sodium bicarbonate as a gas-forming agent. ...

Atenolol, an antihypertensive drug, has poor bioavailability (40-50%) and has has low elimination half life(6 hr). Atenolol is mainly absorbed in the stomach. The floating tablets of atenolol were prepared to increase the gastric retention, extend the drug release and to improve the bioavailability of the drug. The floating tablets were formulated using HPMC 100 cps, sodium alginate, carbopol 9...

The purpose of this research was to prepare and evaluate floating drug delivery system of Lamivudine. Floating matrix tablets of Lamivudine were developed to prolong gastric residence time and increase its bioavailability. Rapid gastrointestinal transit could result in incomplete drug release from the drug delivery system above the absorption zone leading to diminished efficacy of the administe...
