Floating Kollidon SR (KSR) matrix tablets containing famotidine was developed to increase gastric residence time and bioavailability after oral administration. Total six formulations were formulated by direct compression technique using varying concentrations of Kollidon SR (floating agent). The formulations were evaluated for their drug content‚ hardness‚ friability‚ buoyancy lag time‚ total floating time‚ swelling index and invitro drug release. All formulations possessed good floating properties

experiment teaches the students how to determine density‚ volume‚ and percentage errors. OBJECTIVE The objective of this experiment is to determine the order with respect to permanganate ion and to oxalic acid concentration for the reaction of potassium permanganate and oxalic acid solutions. Other goals include‚ writing a rate equation and determining the effect of increased temperature on the rate of this reaction. MATERIALS AND EQUIPMENT The materials required for this experiment include

What is LSD? LSD (lysergic acid diethylamide) is a synthetic (man-made) drug that has been abused for its hallucinogenic properties since the 1960s. If consumed in a sufficiently large dose‚ LSD produces delusions and visual hallucinations that distort the user’s sense of time and identity. LSD typically is sold as a liquid or applied to blotter paper‚ sugar cubes‚ gelatin squares‚ and tablets. LSD generally is taken by mouth. The drug is colorless and odorless but has a slightly bitter taste.
