Erectile dysfunction (ED), or the inability to get and sustain an erection, affects nearly 18 million US men.1 This represents nearly half of all men aged 40 and up.2 Even more surprising, about 26% of men seeking ED treatment are under the age of 40.3
Many effective treatment options for ED exist, yet many men choose not to try them. When researchers analyzed the insurance claims for 6.2 million men, only one-fourth of men diagnosed with ED filled their prescriptions.4 Treatment costs, access, and medication side effects are all probable reasons for not treating ED.
Oral ED medications can have significant unwanted side effects because they must be absorbed from the gut, processed by the liver and kidneys, and distributed throughout the body. Because Trimix and Super Trimix are locally injected, they have far fewer side effects.
Super Trimix is a combination of three medications that all increase blood flow into the penis. Each medication works slightly differently, which allows them to have a synergistic effect when treating ED without the increase in side effects that would be expected when using multiple medications with the same mechanism of action.
Super Trimix is injected into the corpora cavernosa, two large sponge-like chambers inside the penis that fill with blood to generate an erection. Super Trimix’s formula combines three medications: papaverine, alprostadil, and phentolamine, which all increase blood flow into the corpora cavernosa.
Papaverine relaxes smooth muscle lining blood vessels that supply blood flow to the penis and smooth muscle lining the corpora cavernosa. As a result, papaverine increases blood flow into the penis and decreases outflow from the penis. This traps blood in the shaft of the penis and generates an erection. Papaverine acts along several metabolic pathways to increase penile blood flow.
Papaverine has a higher risk of fibrosis and therefore is not used alone.5 It is used in conjunction with phentolamine and prostaglandin to improve ED treatment outcomes while minimizing side effects.
Alprostadil or prostaglandin E1 also relaxes smooth muscles. It can be injected into the corpora cavernosa or used by itself as an intraurethral pellet. Alprostadil is currently the only FDA-approved injectable medication for ED treatment.
Alprostadil’s most common side effects include:5
Alprostadil injections can cause priapism, but its rate of priapism is the lowest of the injectables, at 0.36% to 4%.
Phentolamine is an alpha-adrenergic antagonist that blocks impulses from the sympathetic nervous system. The sympathetic nervous system constricts blood vessels in the penis, which reduces blood flow into the penis. Phentolamine relaxes the smooth muscle in blood vessels and the corpora cavernosa, allowing them to fill with blood. It is commonly used with papaverine.
Super Trimix is a sterile compounded medication that is filled by specialized compounding pharmacies. Since Super Trimix is custom formulated, it can be adjusted to better meet your needs.
Trimix Strength: Papaverine HCl 30 mg/mL, Phentolamine Mesylate 1 mg/mL Prostaglandin E1 10 mcg/mL
Super Trimix strength: Papaverine HCl 30 mg/mL, Phentolamine Mesylate 2 mg/mL Prostaglandin E1 20 mcg/mL
Super Trimix is typically dispensed in a vial with insulin syringes that you use to give yourself the injection. Injected 5 to 10 minutes before sexual activity, erections generally last 30 to 60 minutes.
Following your healthcare provider’s instructions:
When used as prescribed and with a careful injection technique, Trimix side effects are uncommon.
Some people will experience pain, bruising, or a small amount of bleeding while using Super Trimix. When injecting Super Trimix, avoid injecting into a blood vessel and hold pressure on the injection site for five minutes. Doing so will reduce your risk of bleeding and bruising.
Scar tissue may develop, especially if Super Trimix is repeatedly injected in the same location. Therefore, it is very important to change your injection site each time you inject Super Trimix. Do not inject Super Trimix into your urethra or into blood vessels; vary your injection sites along the corpora cavernosa on each side.
Priapism is a prolonged, painful erection. The most common cause of priapism is ED medication use, especially when using ED medications at higher dosages or frequencies than prescribed or using medication that has not been prescribed for you. Overall, the risk of priapism is about 3% to 4%.
When 65 men were asked to rate injection pain from Trimix, their average pain rating was 0.8 out of 10, ranging from 0 to 3. Forty percent of men reported no pain at all.6 In another study, 12% to 15% of men reported injection pain, but most said the pain decreased over the treatment course.7
Super Trimix may also cause a curvature of the penis called Peyronie’s disease. A buildup of scar tissue causes the curvature. Peyronie’s disease is treatable when caught early. It can cause erection problems and pain. Contact your healthcare provider if you notice lumps or fibrous bands under the surface of your penis.
Super Trimix usually starts working in about 5 to 10 minutes, and its effects last an average of 30 minutes or so. To ensure that Super Trimix is working optimally:
Quadmix and Super Quadmix are ED injectables that are made up of the following medications:
Quadmix is sometimes used for men who do not respond to Trimix.
Besides injectables, there are oral ED medications such as sildenafil, vardenafil, avanafil, and tadalafil. These medications are phosphodiesterase class 5 inhibitors (PDE5) that increase nitric oxide levels, which allow blood vessels and smooth muscle in the corpus cavernosa to dilate and fill with blood. Unlike Super Trimix, oral ED medications require sexual stimulation to work. Success rates with Trimix and Super Trimix approach 90% to 95%. Oral ED medications successfully treat 60% to 70% of men with moderate ED. All four PDE5 oral ED medications available in the US have similar levels of effectiveness at any dosage or dosage schedule.8
Common side effects associated with PDE5 inhibitors include:
Injectable ED medications are the most effective non-surgical ED treatment available. Men who experience side effects with oral ED medications, find they are ineffective, or prefer an injectable over an oral medication, are likely to experience treatment success with Trimix or Super Trimix.8 Like all medications, there are risks and benefits associated with using Trimix. However, knowing how to properly use the medication can help you maximize the benefits and reduce the risks.
If you inject too much Super Trimix or use Super Trimix along with another ED medication, you have an increased risk of priapism. Priapism is a prolonged erection. It prevents fresh blood from flowing into the penis and, therefore, can damage the penis tissue. Priapism is rare and manageable, but untreated, it can be extremely painful and can result in impotence.
Priapism is commonly treated with phenylephrine injections, a medication that constricts blood vessels and reduces blood flow into the penis, allowing for detumescence. However, if priapism persists for 3 to 4 hours or pain increases, seek emergency care.
According to the American Urological Association, while oral ED medications are considered first-line, men should be offered all treatment options as long as they are not medically contraindicated. Trimix users are typically men who have tried oral ED medications, but many men are prescribed Trimix or Super Trimix as a first-line treatment due to the side effects associated with oral ED medications.
Super Trimix is a highly effective compounded medication that is a well-tested solution for ED.
