Tolerability of Iron Preparations
Side-effects of oral iron therapy are a common problem.2 GI disturbances such as nausea, heartburn, pain, constipation and diarrhoea are the most commonly reported side-effects.2 These intolerances may impact patient compliance and possibly lead patients to withdraw from treatment.2
Controlled release dosage forms such as ferrograd® control the rate at which the drug is released to provide a sustained drug release over an extended period.
Oral iron therapy in appropriate doses, for a sufficient duration, is an effective first-line strategy for most patients.1
Sustained release oral drug delivery systems may provide
important advantages over conventional oral dosage forms:
- Reduced dosing frequency contributing to improved patient compliance3,4
- Less fluctuation in plasma drug concentrations, thereby improving therapy and decreasing side-effects4
- Sustained plasma drug concentration within the therapeutic range, thereby improving efficacy and decreasing side-effects.4
