ICI (injectibles). Intracavernousal injection therapy (ICI) is the most effective nonsurgical treatment for ED. Intracavernosal injection therapy has been an effective and reliable ED therapy since 1983. Alprostadil, bi-mix (papaverine and phentolamine), and tri-mix (papaverine, phentolamine, and alprostadil) are all injectable vasodilators used to treat ED.
A subcutaneous injection is administered as a bolus into the subcutis, the layer of skin directly below the dermis and epidermis, collectively referred to as the cutis. Subcutaneous injections are highly effective in administering vaccines and medications such as insulin, morphine, diacetylmorphine and goserelin. Subcutaneous, as opposed to intravenous, injection of recreational drugs is referred to as skin popping.
