Probuphine is a medication delivery system designed to help opioid addicts manage their addiction. A buprenorphine implant, it releases a medication that helps to curb cravings for opioids, reducing the likelihood of abuse. The Probuphine implant ensures that users cannot forget to take their medicine, nor can they take too much of it to misuse it. It comes as a Probuphine implant kit, and the device is inserted and removed by a medical doctor when needed.
What Probuphine Is
Probuphine is a medication delivery system manufactured by Titan Pharmaceuticals. Formerly, Braeburn Pharmaceuticals also manufactured the implant, but this ended in 2018. At the moment, the only versions of the medication on the market are made by Titan.
The medication is a buprenorphine implant, delivering steady doses of the drug to the user. Probuphine implants as classified as mixed opioid agonists-antagonists and are available by prescription only.
Probuphine is a scheduled substance due to its primary ingredient, buprenorphine. It is classified as a Schedule III drug by the DEA. This means that it has significant therapeutic applications but also has a risk of abuse.
When patients get a new buprenorphine implant, they have four different implants placed. They are short and tubular and are placed in the arm of the patient. While they can be felt under the skin, they are not readily visible, allowing the user to keep their use of the implant for treating substance addiction a secret at work and in other facets of life.
Probuphine FDA Approval
Probuphine FDA approval has been in place since 2016. This approval was given after Probuphine clinical trials proved it to be both safe and effective for the treatment of opioid dependence in persons who already saw good results with buprenorphine in pill or film form. The FDA noted in their press release announcing their approval that having the medication in implant form addresses concerns regarding misuse, selling, and theft of pill and film forms of the medication. The official Probuphine release date was May 26, 2016.
Probuphine implant approval was revolutionary at the time, as it gave addicts and rehabilitation centers a safe and robust alternative to conventional medications. For example, those who do not respond well to Naltrexone could be switched to the implant. Probuphine FDA clearance also meant that it was more likely to be covered by insurance than other implants that are considered experimental. However, Probuphine approval does not mean it is perfectly safe in all cases, and patients should be aware of that.
What Probuphine Is Used For
The buprenorphine implant is for opioid addiction treatment.
Off-label uses are also being studied, such as Probuphine for chronic pain.
The Probuphine mechanism of action is twofold. First, it is a partial agonist at the mu-opioid receptor; second, it is an antagonist at the kappa-opioid receptor. Together, these work to eliminate cravings for opioids and block their effects.
Probuphine implant placement is done by a medical professional, usually in an office setting or at a rehabilitation center. Injecting Probuphine is done using a particular instrument and under local anesthetic. How long Probuphine lasts is roughly six months, after which the implant must be removed and replaced.
It should be noted that Probuphine expulsion is possible should the body reject the implant. It also may migrate away from the implant site. Users must carefully monitor the implants and notify their doctor if they feel it is being rejected or migrating.
For doctors to prescribe the medicine over other medications, such as Methadone, it must offer clear benefits. The primary benefits of implant buprenorphine come down to how the drug is administered. Because it is an implant, users cannot manipulate the medication to abuse it. Nor can they forget to take it or have it stolen.
Buprenorphine implant effectiveness has been documented for more than a decade, starting with clinical trials by Titan Pharmaceuticals. The success rate of Probuphine is impressive. At the time of FDA approval, studies showed that 89 percent of users remained clean of opioid use after six months—the point at which the implant must be replaced. Buprenorphine on its own is a success in opioid addiction treatment, decreasing heroin overdose deaths in Baltimore by 37 percent. By removing the chance of discontinuing use or forgetting doses, the implant can only improve these statistics.
Ultimately, the Probuphine opioid implant is an effective way to manage certain addictions. However, it will not be the right choice in all cases.
Probuphine Risks and Side Effects
Probuphine side effects are numerous. For many users, the risk of experiencing them is worth it. For others, these effects are enough to discontinue use. Common implant side effects include:
- Pain, itching, redness, and swelling at the implant site
- Abdominal pain
- Back pain
- Mouth and throat pain
- Weakness or lack of energy
- Chest pain
- Feeling cold
- Skin scratching
- Pain in extremities
- Numbness and tingling
- Shortness of breath
- Skin lesions
The majority of these side effects of Probuphine are mild and go away after the body adjusts to the implant. However, some carry serious risks. For example, numbness and tingling can indicate nerve damage, which is why there is a Probuphine black box warning regarding neurological side effects, up to and including death.
Other risks must be considered, as well. For example, Probuphine and liver disease are contraindicated, as the medication can worsen the illness. Other complaints include itchiness not unlike that experienced when withdrawing from opioids, fatigue that prevents the user from living a productive life, and severe depression, leading to suicidal thoughts.
The buprenorphine implant is known to have interactions with other medications and substances, including alcohol and street drugs. Users should never take medication, drink, or engage in drug use while on the medication unless their doctor indicates that there is no risk of interactions. Substances known have serious interactions with the medicine include:
- Central nervous system depressants, especially benzodiazepines, alcohol, and illegal opiates
- Inhibitors of CYP3A4
- CYP3A4 inducers
- Antiretrovirals: Non-nucleoside reverse transcriptase inhibitors (NNRTIs)
- Antiretrovirals: Protease inhibitors (PIs)
- Antiretrovirals: Nucleoside reverse transcriptase inhibitors (NRTIs)
- Serotonergic drugs
- Monoamine oxidase inhibitors (MAOIs)
- Muscle relaxants
- Anticholinergic drugs
It is vital that users are honest with their doctor about the medications and other substances they are using, as if they are not, death could result.
Getting High on Probuphine
People who are prescribed the implant are addicts attempting to enter and stay in recovery. As such, it does not come as a surprise that some would be curious about using Probuphine to get high. The question is if it is possible.
Recreational Use of Probuphine
The Probuphine experience is not one of euphoria as the medication is designed specifically to prevent that sensation and is also released in such low doses that achieving a high from the subdermal alone is not possible.
This brings up the question of if Probuphine high is possible with other medications. While this cannot be ruled out at the moment, there is nothing to indicate that mixing the medication with other substances can produce a high from the medicine itself. More likely is the user overdosing due to taking too much of a substance in hopes of overriding the implant and getting high.
Getting High on Other Drugs
The subdermal is designed to prevent cravings for opioid medications and stop users from experiencing the high that those medications produce. This means that it is possible for users to get high on other types of medications and substances while using the implant. However, the patient would need to remove the implant to get high on opiates.
Given the effectiveness of the implant, many may wonder why more addicts do not use it. For many, it comes down to the Probuphine implant cost. While access to it may be a matter of life and death for many, affording it is not always simple.
General Prices and Coupons
Because medicine is an implant that must be placed by a medical professional, users cannot simply take a prescription to a pharmacy and get it. While it still needs to be prescribed, it is the doctor who accesses the medication—not the patient. As such, it cannot be purchased in-store or online and finding ways to save on it, such as with coupons, is all but impossible.
For many opiate addicts, this is more than they can afford, especially those who are unemployed due to their drug use.
For users with insurance coverage, the Probuphine cost may be reduced or even free, depending on their insurance policy limits. However, not all companies will cover all or part of the buprenorphine implant cost. Because the medication in pill and film form is cheaper, they can refuse to allow coverage of the implant over the alternatives.
How Probuphine Is Accessed
Not every physician will be comfortable with prescribing buprenorphine implants, nor are all allowed to insert them. Users need to find a doctor who is comfortable with Probuphine prescription and is certified in placing the implants. For this, it is suggested that people seek out Probuphine doctors near them or turn to a drug rehabilitation clinic. There, it is highly likely that there will be easy access to an experienced doctor who has been given the proper training in placing the medication.
There are significant risks and complications that can arise from improper insertion of the implant. This is why doctors are required to undergo buprenorphine implant training before they can insert the medication. This training is offered by Titan Pharmaceuticals and results in a specialized certification for the medical professional. Probuphine training recertification is required every so many years to ensure the best results.
Probuphine and Drug Screenings
The medication can show up on any drug test that is screening for buprenorphine. Because it is an implant that continuously disperses low doses of medicine, no Probuphine half-life can be used to determine how long the drug will be detected while in active treatment. Once the implants are removed or have fun out of medication to disperse, the user can go by the buprenorphine half-life, which is 37 hours.
How long Probuphine stays in the system after implant removal will vary from person to person. A Probuphine drug test should be able to detect the medication in the saliva for about a week, in the urine for several weeks, and in the hair for as long as a year. Thus, how long the buprenorphine implant lasts for a drug test will depend on the test being administered.
Ultimately, a buprenorphine implant test is a rare thing, and as long as the user has a valid prescription, they should be safe.
The subdermal itself is not considered to be addictive. However, its active ingredient, buprenorphine, is. Probuphine is addictive by the association in that it is possible to be addicted to the main medication within the implant. However, because the amount of the drug released by the implants is so low, medical professionals do not consider the implant itself to be addictive.
When used properly, Probuphine is an effective way to manage opioid addiction. However, it cannot be accessed through a regular doctor. Addicts should seek treatment at a drug rehabilitation center where the medication can be prescribed and implanted.
