A study was carried out to evaluate some parameters which may have an effect on the dissolution rate of prednisone from tablets. The parameters examined involving formulation were: diluent proportion (Lactose-starch), dissintegrant type (starch, explotab (sodium starch glycolate) type of binder (...
Factors Affecting Dissolution Lesson Summary Frequently Asked Questions What is an example of dissolution? One typical example of dissolution is sodium chloride (commonly known as salt) dissolving in water. Water molecules surround and separate sodium from chloride ions. Other examples of dissolution in...

Passage A: Pharmaceutical Factors Affecting Drug Bioavailability In order to design a drug product that will deliver the active drug in the most bioavailable form, the pharmacist must consider (1) the type of drug product (e.g. solution, suspension, suppository); (2) the nature of the exc...
of sugar in water takes place faster when the water is hot as compared to the rate of dissolution in cold water. The increase in temperature increases the energy of the reactant molecules, making them move faster and more susceptible to collisions, thereby increasing the reaction rate. ...

Factors Affecting Bioleaching 1. Choice of Bacteria The bacteria must survive and thrive under extreme conditions such as high temperatures, acidic environments, and elevated concentrations of heavy metals. Their efficiency directly impacts the bioleaching process. Most used microorganisms are chemolithotrophi...
Temperature is one of the important factors affecting solubility. Generally, solubility increases with increasing temperature and decreases with decreasing temperature. This is because the spacing between solute particles increases during the dissolution process, making the dissolution process easier. ...
