Packaging plays a crucial role in ensuring the safety, integrity, and proper dispensing of pharmaceutical products. There are several types of common pharmaceutical packaging: unit-dose packaging individually packages each dose of medication and is used in hospitals to reduce medication errors; blister packaging consists of individual cavities for each dose and is used for over-the-counter medications; bottle packaging varies in size depending on the quantity prescribed and is used for liquid medications. Proper packaging helps protect products from factors like light, moisture, and temperature fluctuations that can affect stability and efficacy.
