What are the disadvantages of suspension?
v) Drug in suspension exhibits a higher rate of bioavailability compared to the same drug of equivalent dose formulated in tablets or capsules. This is due to larger surface area and high dissolution, e.g., antacid suspension. 1. Sedimentation of solids occasionally gives poor form of product.
What is the difference between suspension and solution?
The difference between a solution and a suspension is in the particle sizes involved. A solution is a mixture of ions or molecules (very, very small). Solutions are transparent, meaning that you can see through them. A suspension has bigger particle sizes and so it may look cloudy or murky.
Which is better suspension or syrup?
