Which drug requires protection from light?

Certain medications are sensitive to light and require protection to maintain their stability and efficacy. Amphotericin B is known to degrade when exposed to light, which can lead to reduced potency. Similarly, Cisplatin is also prone to photodegradation, so it often must be shielded from light during administration. Metronidazole, while less commonly referenced in discussions about light sensitivity, does possess some light sensitivity, necessitating precaution during storage and handling.

Since all of these drugs are affected by light exposure, it is critical to use protective measures such as brown bags or opaque containers when preparing and administering these medications. Therefore, the correct choice encompasses all options, confirming the need for light protection for each of these drugs.
