What is the concentration of Diphenoxylate and Atropine in a Schedule V (CV) controlled substance per dosage unit?

  1. 0.5/25mg

  2. 1/25mg

  3. 2/25mg

  4. 2.5/25mg

The correct answer is: 0.5/25mg

Diphenoxylate and Atropine are two active ingredients found in Schedule V (CV) controlled substances. This means that they have a low potential for abuse and a low risk of dependence. The concentration of Diphenoxylate and Atropine in a Schedule V controlled substance per dosage unit is 0.5mg of Diphenoxylate and 25mg of Atropine. Therefore, option A is the correct answer. Option B, C, and D are incorrect because they either have the incorrect ratio of Diphenoxylate to Atropine (125, 2:25, 2.5:25), or they have the incorrect dosage amount for Atropine (25mg). This makes them not consistent with the drug's designated concentration of 0.5/25mg per dosage unit. In summary, option A is the correct answer because it accurately reflects the concentration of Diphenoxylate and Atropine in a Schedule V controlled substance per dosage unit, while the other options have either incorrect ratios or dosages.
