What is the principle of dissolution?
Dissolution is the process in which a substance forms a solution. Dissolution testing measures the extent and rate of solution formation from a dosage form, such as tablet, capsule, ointment, etc. The dissolution of a drug is important for its bioavailability and therapeutic effectiveness.
What is the importance of dissolution rates?
Its significance is based on the fact that for a drug to be effective, it must first be released from the product and dissolve in the gastrointestinal fluids before absorption into the bloodstream can happen. In other words, the rate and extent of drug absorption are determined by its dissolution from the dosage form.
What is drug dissolution profile?
• Dissolution test is one of the most valuable in vitro tests used. to assure the drug product quality. • Similar dissolution profile is in general considered as an. assurance of product sameness and product performance in. the presence of scale-up and SUPAC changes.
How do you determine dissolution media?
The selection of a dissolution medium should be based on drug substance and formulation characteristics as well as on interactions among components. include acidic solutions, buffers, surfactants, and surfactants with acid or buffers (1).
Why is 900 ml dissolution media?
Most likely, the volume was lowered to 900mL to account for volume displacement from the product and stirring shaft. This gives some wiggle room in the test, so that the vessel doesn’t spill over during the dissolution.
Why we use only six bowls for dissolution of a drug?
The use of six dosage units as the basic sample size in dissolution is partially due to the configuration of the dissolution test assembly with six positions.
What is f1 and f2 in dissolution?
The fit factors can be expressed by two approaches: f1 (the difference factor) and f2 (the similarity factor). Two dissolution profiles to be considered similar and bioequivalent, f1 should be between 0 and 15 whereas f2 should be between 50 and 1006.
