WebJul 25, 2024 · First order kinetics refers to chemical reactions whose rate of reaction depends on the molar concentration of one reactant. The rate of the reaction is proportional to the concentration of one reactant. There can be many other reactants taking part in the chemical reaction, but only one reactant will determine the rate of the reaction. WebMar 16, 2024 · The main principle of pseudo-zero-order kinetics is that the drug concentration is kept constant throughout course of reaction. Therefore, degradation rate does not depend on the concentration of the drug at saturation. Pseudo-zero-order reactions are mainly seen in solid dosage forms and suspensions. novalgen therapeutics
