Long-acting injectables are favored in the medical field due to their effectiveness and convenience, as their injection methodology allows for the gradual release of medication into the bloodstream. In post-operative care, the alleviation of pain is vital not only for recovery, but for the comfort of the patient. With the help of long-acting injectable drugs for post-surgical pain management, patients can experience a more effective recovery.

The History of Long-Acting Injectables

Long-acting injectable drugs were first introduced as a treatment for people with chronic schizophrenia. These long-acting injectable antipsychotic drugs were created as an effort to solve the issue of poor adherence to oral medications. Some notable points in the history of long-acting injectables include the following:

• 1950s – 1970s – Long-acting injectables were created to help manage conditions such as schizophrenia. In 1952, chlorpromazine (CPZ) was developed in Paris, offering an effectiveness greater than that of older drugs on the market. Then in 1966, thanks to G.R. Daniels, a medical director at the time, the first long-acting injectable was created. This first injectable was AP fluphenazine enanthate, with fluphenazine decanoate being created just eighteen months later.
• 1980s – 1990s – During this time, long-acting injectables for second-generation antipsychotics were introduced. Between 1988 and 1992, Risperidone was first developed by Janssen-Cilag. Its purpose was to treat behavior issues in children and adolescents.
• 2000s – present – Long-acting injectables have come a long way since their creation. With their medication methodology, they can provide better adherence to timelines, facilitate proper dosing, and free patients from having to take oral medications every day. With continuing research on long-acting injectables, we are seeing uses in areas such as contraception, chronic and acute pain, antiretroviral therapy, and more.

The Role of Long-Acting Injectables for Post-Surgical Pain Management

A key factor of post-surgical work is minimizing patient pain, giving them the time they need to heal. With the use of extended-release drugs for post-surgical pain management, doctors are better able to effectively manage pain for their patients and promote an expedited recovery process.

Types of Injectables Used for Post-Surgery

NSAIDs, or nonsteroidal anti-inflammatory drugs, are medications that reduce fever, pain, and inflammation. Looking at postoperative care, NSAIDs help in mitigating pain, minimizing the reliance on opioids, and fostering a healing environment. You may be familiar with some over-the-counter NSAIDs such as ibuprofen or aspirin.

NSAIDs are known to prevent blood from clotting, which can definitely be beneficial in post-surgery situations. In cases such as orthopedic procedures that involve prolonged immobility, there is an increased risk of blood clot formation. NSAIDs help prevent that blood clotting, specifically in the veins.

Some common NSAIDs that have been used as long-acting injectables for post-surgery pain management include:

• Toradol (Ketorolac) – This NSAID is used to relive pain and is commonly available in injection or tablet form. The injections work about thirty minutes after administration and the effects can last up to six hours. Often prescribed for post-surgery pain, it typically is distributed as a one-time injection. However, some people may receive a shot every six hours. This will depend on factors such as body weight, age, drug interactions, and others.
• Diclofenac sodium – This medication is another NSAID used to treat adults with mild to moderate pain. It can be used for osteoarthritis, low back pain and for post-operative patients. Similar to Toradol, the effects may start to work immediately after the injection.
• Caldor – This ibuprofen injection works by reducing fever and treating pain in the body. It helps manage pain as an adjunct to opioid analgesics.
• Ketoprofen – Ketoprofen can help with acute and chronic pain, both for the traumatic and rheumatic origin. Additionally, it can help alleviate postoperative pain, specifically in the orthopedic field. While ketoprofen is offered as an injectable, that is not the intended use for humans. There is an oral tablet for humans, only available with a doctor’s prescription. The injectable form is actually intended for animals, such as horses. In horses, it’s used for musculoskeletal pain or inflammation, abdominal pain, and other inflammatory conditions. It can also be used effectively for cattle, goats, sheep, and pigs.
