Parenteral controlled substances refer to medications that are administered via injection or infusion, and are regulated by government agencies due to their potential for abuse, dependence, and addiction. These substances are classified into different schedules based on their medical use, potential for abuse, and safety profile. In the United States, the Drug Enforcement Administration (DEA) is responsible for regulating and scheduling controlled substances, including parenteral controlled substances.
Classification and Scheduling of Parenteral Controlled Substances
The DEA classifies controlled substances into five schedules, ranging from Schedule I (high potential for abuse and no accepted medical use) to Schedule V (low potential for abuse and accepted medical use). Parenteral controlled substances are typically classified as Schedule II or Schedule III, as they have a high potential for abuse, but also have accepted medical uses. Examples of parenteral controlled substances include fentanyl, morphine, and hydromorphone, which are used to manage moderate to severe pain.
Schedule II Parenteral Controlled Substances
Schedule II parenteral controlled substances have a high potential for abuse, but also have accepted medical uses. These substances are typically used to manage severe pain, and are often used in hospital settings or in patients who have failed other treatments. Examples of Schedule II parenteral controlled substances include:
- Opioids, such as fentanyl and morphine, which are used to manage severe pain
- Barbiturates, such as pentobarbital, which are used to induce sedation and anesthesia
- Amphetamines, such as methamphetamine, which are used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy
Schedule III Parenteral Controlled Substances
Schedule III parenteral controlled substances have a lower potential for abuse than Schedule II substances, but still have accepted medical uses. These substances are often used to manage moderate pain, and are typically used in outpatient settings. Examples of Schedule III parenteral controlled substances include:
- Ketamine, which is used to induce sedation and anesthesia
- Codeine, which is used to manage mild to moderate pain
- Hydrocodone, which is used to manage mild to moderate pain
| Substance | Schedule | Medical Use |
|---|---|---|
| Fentanyl | Schedule II | Severe pain management |
| Morphine | Schedule II | Severe pain management |
| Ketamine | Schedule III | Sedation and anesthesia |
Regulations and Guidelines for Parenteral Controlled Substances
The use of parenteral controlled substances is heavily regulated, and healthcare professionals must follow strict guidelines when prescribing or administering these substances. In the United States, the DEA requires that healthcare professionals register with the agency and obtain a DEA number to prescribe or administer controlled substances. Additionally, healthcare professionals must follow strict record-keeping and documentation guidelines, and must ensure that patients are properly educated on the use and risks of these substances.
Prescription Requirements
Prescriptions for parenteral controlled substances must be written on a tamper-resistant prescription pad, and must include the patient’s name, address, and date of birth. The prescription must also include the name and strength of the substance, as well as the dosage and frequency of administration. Healthcare professionals must also ensure that patients are properly educated on the use and risks of these substances, and must provide written instructions on how to use the substance safely and effectively.
Administration Requirements
The administration of parenteral controlled substances must be performed by a licensed healthcare professional, and must be done in a safe and controlled environment. Healthcare professionals must ensure that patients are properly monitored during and after administration, and must be prepared to respond to any adverse reactions or emergencies. Additionally, healthcare professionals must follow strict protocols for handling and disposing of these substances, and must ensure that all equipment and supplies are properly sterilized and maintained.
What is the difference between Schedule II and Schedule III parenteral controlled substances?
+Schedule II parenteral controlled substances have a high potential for abuse, but also have accepted medical uses. Schedule III parenteral controlled substances have a lower potential for abuse, but still have accepted medical uses. Schedule II substances are typically used to manage severe pain, while Schedule III substances are used to manage moderate pain.

Future Implications and Emerging Trends
The use of parenteral controlled substances is constantly evolving, and healthcare professionals must stay up-to-date on the latest regulations, guidelines, and emerging trends. One emerging trend is the use of abuse-deterrent formulations, which are designed to prevent tampering and misuse. Another emerging trend is the use of opioid-sparing strategies, which aim to reduce the use of opioids and minimize the risk of addiction and dependence.
Abuse-Deterrent Formulations
Abuse-deterrent formulations are designed to prevent tampering and misuse, and are typically used to manage severe pain. These formulations can include extended-release or controlled-release formulations, which are designed to release the substance slowly over time. Other abuse-deterrent formulations include sublingual or transmucosal formulations, which are designed to be absorbed quickly and minimize the risk of tampering.
Opioid-Sparing Strategies
Opioid-sparing strategies aim to reduce the use of opioids and minimize the risk of addiction and dependence. These strategies can include the use of non-opioid analgesics, such as acetaminophen or ibuprofen, or the use of adjuvant therapies, such as physical therapy or cognitive-behavioral therapy. Other opioid-sparing strategies include the use of regional anesthesia or nerve blocks, which can help to reduce pain and minimize the need for opioids.
