ORDER OF REACTION - PharmaQuesT
pharmaquest.weebly.comWhen the reaction rate is independent of concentration of the reacting substance, it depends on the zero power of the reactant and therefore is zero order reaction. In this type of reaction, the limiting factor is something other than concentration, for example, solubility or absorption of light in certain photochemical reactions.

chapter 1 Controllingdrugdelivery
www.pharmpress.comFor dosage forms it is common to differentiate the various types by classifying them according to their physical state into gaseous (e.g. anaesthetics), liquid (e.g. solutions, emulsions, suspensions),semisolid(e.g.creams,ointments, gels and pastes) and solid dosage forms (e.g. powders, granules, tablets and capsules).
TYPES OF DOSAGE FORMS - Weebly
pharmasy.weebly.comTypes of dosage forms: Definition: Dosage forms are the means by which drug molecules are delivered to sites of action within the body. The need for dosage forms: 1- Accurate dose. 2- Protection e.g. coated tablets, sealed ampules. 3- Protection from gastric juice. 4- Masking taste and odour. 5- Placement of drugs within body tissues.
