Development and evaluation of gastroretentive norfloxacin floating tablets

Development and evaluation of gastroretentive norfloxacin floating tablets.

Floating matrix tablets of norfloxacin were developed to prolong gastric residence time, leading to an increase in drug bioavailability. Tablets were prepared by the wet granulation technique, using polymers such as hydroxypropyl methylcellulose (HPMC K4M, HPMC K100M) and xanthan gum. Tablets were evaluated for their physical characteristics, viz., hardness, thickness, friability, and mass vari...

Formulation and Evaluation of Gastroretentive Floating Microballoons of Norfloxacin

Preparation and evaluation of gastroretentive floating tablets of Silymarin.

The present study performed by preparation and evaluation of floating tablets of Silymarin as model drug for prolongation of gastric residence time. Floating effervescent tablets were formulated by various materials like hydroxypropyl methylcellulose (HPMC) K 4M, K 15M, psyllium husk, swelling agent as crospovidone and microcrystalline cellulose and gas generating agent like sodium bicarbonate ...

Formulation and Evaluation of Gastroretentive Floating Tablets of Domperidone Maleate

The low bioavailability (15%) and good solubility of Domperidone Maleate in acidic pH following oral administration favours development of a gastro retentive formulation. Gastroretentive floating matrix tablets of Domperidone Maleate were successfully prepared with hydrophilic polymers like HPMC K4M, HPMC K15M and HPMC K100M. From the Preformulation studies for drug excipients compatibility it ...

Formulation Development and In-Vitro Evaluation of Gastroretentive Floating tablets of Atenolol

The purpose of the study was to prolong the gastric residence time and increase the bioavailability of atenolol by designing its floating tablets and to study the influence of different polymers on its release rate. It was selected as a model drug, because it is poorly absorbed from the lower GIT. The tablets were prepared by direct compression technique, using different polymers such as hydrox...
