A skin patch is a bandage-like device that delivers medication through the skin into the body. The core function of a skin patch is to provide a steady and slow release of medicine directly into the bloodstream.
How a Skin Patch Works
The reference provided clarifies how these patches function:
- Medication Delivery: A skin patch contains a specific dosage of medication. When applied to the skin, the medication gradually passes through the skin layers and enters the bloodstream.
- Slow and Steady Release: Unlike oral medications, which might lead to rapid spikes and drops in the medicine’s concentration in the blood, a skin patch ensures a consistent level of medication over a period of time. This controlled release is designed to maintain therapeutic levels and reduce side effects associated with variable dosing.
- Convenience: Skin patches are a convenient alternative for people who may have difficulty swallowing pills or need a continuous release of medication.
