Final answer:
Controlled substances in an Institutional Class I (Nursing Home) Pharmacy are typically destroyed through methods like high-temperature incineration and proper disposal systems.
Step-by-step explanation:
In an Institutional Class I (Nursing Home) Pharmacy, controlled substances are typically destroyed following specific guidelines to ensure proper disposal.
One method commonly used is high-temperature incineration, which involves burning the substances at temperatures higher than 1000 degrees Celsius. This process helps to eliminate any pharmaceutical or ecotoxic activity and prevent the environmental formation of new products.
In addition, proper disposal systems such as take-back programs are important to prevent improper disposal of unused or expired drug residues, which can contribute to environmental pollution.
