 ICP treatment has been used to help create and maintain erections in patients who do not respond to more mainstream medications or are prohibited from taking these drugs because of a heart condition, diabetes or blood pressure since ICP treatments are localized and do not typically interact with other systemic medications.Intracavernous pharmacotherapy can be used in patients with a wide variety of ailments wherein other medications might not be as effective.For example, a study showed that over seventy percent of patients with a spinal cord injury responded positively to intracavernous pharmacotherapy and were able to achieve an erection.
