What adverse effect may be observed with the dosage form of Nifedipine?

The presence of the tablet or shell in stool is a known observation with Nifedipine, particularly when it is formulated as an extended-release capsule or tablet. This occurs because the medication is designed to release its active ingredient gradually over time. The outer shell of the tablet may not fully dissolve in the gastrointestinal tract, which can lead to the observation of the shell in the stool. This is a common phenomenon with certain oral dosage forms where the inert shell is excreted without being completely digested.

Understanding this effect is important for patients and healthcare providers to differentiate between a normal occurrence and a potential indication of improper absorption or medication efficacy. Knowing that medication shells can appear in stool helps reassure patients and encourages adherence to their prescribed treatment without unnecessary alarm.
