For men who have tried oral medications for erectile dysfunction and found them ineffective or poorly tolerated, there are other evidence-based options worth knowing about. Compounded injection therapy — specifically BiMix and TriMix — has been used for decades and remains one of the most effective treatments available for ED, particularly in cases where oral medications fall short.

What Are BiMix and TriMix?

BiMix and TriMix are compounded medications that are injected directly into the erectile tissue of the penis before sexual activity. They work by relaxing smooth muscle and dilating blood vessels, which allows increased blood flow and produces an erection. BiMix typically contains two active medications — papaverine and phentolamine. TriMix adds alprostadil as a third component. Both are prepared by a compounding pharmacy and dispensed under a physician's prescription. The formulations can be customized in concentration based on what your doctor determines is right for you.

Why Would a Doctor Recommend This?

Oral medications like sildenafil and tadalafil work by enhancing the natural response to sexual stimulation. However, they do not work for everyone. Men with certain underlying conditions — including diabetes, prostate cancer treatment history, cardiovascular disease, or nerve damage — may find that oral medications produce insufficient results. In these cases, injection therapy can be highly effective because it acts directly on the blood vessels, bypassing some of the physiological pathways that oral medications rely on.

Is the Injection Painful?

Most men are understandably hesitant about the idea of self-injection, but patients who use this therapy regularly report that the discomfort is minimal. The needles used are very fine, similar to those used for insulin. Your urologist or prescribing physician will typically train you on the proper injection technique before you begin self-administering at home. Proper technique is essential both for effectiveness and for avoiding complications.

Why Does It Need to Be Compounded?

TriMix in its exact three-component formulation is not available as a commercially manufactured product. It must be compounded by a licensed pharmacy. The concentrations of each active ingredient can also be adjusted based on your individual response and your doctor's recommendation. This is one of the key advantages of working with a compounding pharmacy — the ability to tailor the formulation to what actually works best for you rather than accepting a one-size-fits-all product.

Storage and Handling

Compounded BiMix and TriMix require refrigeration to maintain potency and should be handled carefully. Your pharmacy will provide clear instructions on storage, expiration, and handling. Kearney Park Pharmacy ships these medications in temperature-controlled packaging to ensure they arrive in optimal condition.

For people living with severe dry eye disease, the daily discomfort can feel relentless — burning, stinging, light sensitivity, and blurred vision that interferes with work and quality of life. Artificial tears and prescription drops help many patients, but for those with more advanced disease, something more may be needed. Autologous serum eye drops are a specialized treatment that may offer significant relief when other options have not been enough. What Are Autologous Serum Eye Drops? Autologous serum eye drops are made by taking a sample of your own blood, separating the serum from the red blood cells, and diluting it with a sterile solution. The resulting drops contain many of the same growth factors, vitamins, and proteins naturally found in healthy tears — components that commercial artificial tears simply cannot replicate. Because they come from your own body, the risk of rejection or allergic reaction is essentially zero. Who Can Benefit? Autologous serum drops are typically considered for patients with moderate to severe dry eye disease who have not found adequate relief from standard treatments. They are frequently used in conditions such as Sjogren's syndrome-related dry eye, ocular graft-versus-host disease, neurotrophic keratopathy, severe aqueous-deficient dry eye, and significant ocular surface damage from chronic contact lens use. Your eye doctor will determine whether you are a candidate based on your specific diagnosis and history. What Is the Process? Your doctor will write a prescription for autologous serum eye drops. A blood draw is then required — this can be done at a lab or through a coordinating service. Once the blood is received by the compounding pharmacy, the serum is separated, diluted to the appropriate concentration (commonly 20% or 50%), and dispensed in sterile vials. The drops are kept frozen to preserve their potency and are thawed as needed. How Are They Used? Autologous serum drops are typically used multiple times per day, as directed by your eye doctor. They should be stored in the freezer — you thaw one vial at a time for daily use while the rest remain frozen. Most preparations have a beyond-use date established by th compounding pharmacy, and your prescriber will schedule regular follow-up to monitor your response to treatment. Is This Covered by Insurance? Coverage varies by insurance plan and diagnosis. Your prescribing provider can assist with prior authorization documentation if needed. Kearney Park Pharmacy can help answer questions about the prescription process and shipping logistics. Available Across Texas from Kearney Park Pharmacy Kearney Park Pharmacy prepares autologous serum eye drops as a sterile compounded preparation under USP 797 standards.

For patients with aqueous-deficient dry eye disease unresponsive to conventional therapy, autologous serum eye drops remain one of the strongest evidence-based options in the ophthalmologist's armamentarium. Multiple controlled trials and case series have demonstrated improvements in corneal staining, OSDI scores, and symptom burden in patients with Sjogren's syndrome, GVHD, neurotrophic keratopathy, and other severe ocular surface conditions. The clinical barrier to prescribing is largely logistical — and a well-organized compounding pharmacy relationship resolves most of it. Why Autologous Serum Works Serum contains growth factors (EGF, TGF-beta, fibronectin), vitamins, and immunoglobulins that closely replicate the biochemical composition of healthy human tears. These components support corneal epithelial healing, reduce inflammation, and maintain surface integrity in a way that no currently available commercial formulation can match. Commercial cyclosporine and lifitegrast address the inflammatory component, but do not provide the structural and growth factor support that serum delivers — making these treatments potentially complementary rather than competitive. Concentration and Formulation The two most studied concentrations are 20% and 50% serum diluted in sterile 0.9% sodium chloride. The 20% concentration is commonly used as a starting point. The 50% concentration is preferred in patients with more severe disease, GVHD, or inadequate response to 20%. Some protocols use higher concentrations in refractory cases. Kearney Park Pharmacy can prepare autologous serum at the concentration you specify. We recommend clearly stating the concentration, quantity of vials, and refill authorization on the prescription to streamline processing. Blood Collection and Chain of Custody Blood draw coordination is a common workflow question. Patients typically have blood drawn at a local lab and arrange shipping to the compounding pharmacy via overnight service. Kearney Park Pharmacy can provide the collection kit instructions and shipping requirements to your office so that patients are properly prepared. A clear chain of custody from draw to preparation is maintained in our documentation. Sterile Compounding and Frozen Shipping We prepare autologous serum drops aseptically under USP 797 conditions in our ISO-classified cleanroom. Vials are dispensed in unit-dose format and shipped frozen using validated cold-chain packaging to maintain product integrity during transit. We ship across Texas, making this therapy accessible to your patients regardless of proximity to our Mesquite location. Coordinating Refills for Your Patients For patients on chronic autologous serum therapy, we can coordinate refill scheduling to minimize lapses. We recommend establishing a refill rhythm tied to the patient's remaining vial supply and scheduling the next blood draw accordingly. Your office can be notified when a new prescription or refill authorization is needed. Establish a Prescriber Relationship If you are treating patients with ocular surface disease and want a reliable sterile compounding source for autologous serum, we would welcome the opportunity to work with your practice.
