Final answer:
The strength limit for narcotic C-III substances varies but generally refers to medications that are less potent than Schedule II drugs and are used as analgesics, potentially causing drowsiness at higher doses. Naltrexone is an example of a treatment used for narcotic addiction that is effective in higher doses of 50 to 100 mg.
Step-by-step explanation:
The strength limits for a narcotic C-III substance refer to the classification of drugs that, while still possessing a potential for abuse, have an accepted medical use and if abused, may lead to moderate or low physical dependence or high psychological dependence. Medications in this category often serve as analgesics, which reduce pain without loss of consciousness at lower dosages but may induce drowsiness andconsciousness when used in higher dosages.
Examples of narcotics in this category include but are not limited to products containing not more than 90 milligrams of codeine per dosage unit (like Tylenol with codeine), and drugs like buprenorphine.
To manage narcotic addiction, medications such as naltrexone, which is an antagonistic and prevents opioids from having their usual effect, are used. It requires a dosage of 50 to 100 mg because of its oral absorption properties and longer action, therefore, it is beneficial in maintaining chronic therapy in narcotic treatment programs.
