Pseudo-Zero Order Reactions - Formulation Studies

Pseudo-Zero Order Reactions are key in controlled drug delivery ensuring steady plasma levels.
Not a true kinetic order, but appears zero-order due to constant concentration of one or more reactants.
Occurs when a reactant is in large excess or is replenished (e.g., oxygen or water in excess).

Often used in formulation studies where degradation appears to follow zero-order despite being inherently higher order.
