Answer 1

Answer:

C) It's a centrally acting antitussive and can cause dependence.

Answer 2

Answer:

C. It's a centrally acting antitussive and can cause dependence.

Explanation:

This is the correct statement that adequately explains codeine. Codeine is an opioid analgesic, which means that it is used to decrease pain by increasing the threshold for pain, this increasing the quality of life of patients. Codeine, like other opiates, is obtained from the poppy plant, Papaver somniferum (Papaveraceae) However, codeine can be problematic because it can cause addiction.
