Official title
Evaluation of Efficacy of Botulinum Toxin A Plus Oral Tadalafil 5 mg in Diabetic Men With Erectile Dysfunction Not Responding to Approved Oral or Intracorporeal Vasoactive Treatments.
Overview
Study is aiming to evaluate safety, efficacy and durability of intracavernosal injection (ICI) of Botulinum toxin A plus oral tadalafil in controlled diabetic men with refractory Erectile Dysfunction.
Detailed description
Total of (32) male patients will be included in this study and will be recruited from the Andrology, Sexology \& STDs outpatient clinics- Faculty of medicine -Cairo and Aswan Universities. All those patients are complaining of erectile dysfunction Unresponsive to Approved Pharmacological Treatments. Each patient will have an informed consent obtained prior to conducting the study.
All patients will be subjected to the following:
* History taking. * Clinical examination (general and local genital examination). * International Index of Erectile Function (IIEF-5) before and after treatment (Rosen et al., 2002). * Erection Hardness Score (EHS) before and after treatment (Mulhall et al., 2006). * Global assessment questionnaire after treatment (Giuliano et al., 2007).
* All patients will be examined by Duplex Doppler ultrasonography in the basal condition and after the induction of penile erection with the assistance of an intracavernous injection of alprostadil 20 μg/mL. * All patients will receive single dose of ICI of 100u of (BTXA) combined with 5mg oral Tadalafil once daily for 3 months. * The subjects will be re-examined and International Index of Erectile Function (IIEF-5), Erection Hardness Score (EHS)and penile color Doppler ultrasound with PGE-1 injection will be done at 6 and 12 weeks from the start of therapy in addition to Global assessment questionnaire will be done at 12 weeks from the start of therapy
\* Procedure * The patients will lied down in supine position. After cleansing the skin with alcohol, intracavernosal injection of single dose 100U (BTX-A) diluted in isotonic saline 2cm proximal to coronal margin at right and left sides will be performed and the injection site will be pressed directly for two minutes.

Interventions
- Drug Botulinum toxin A
Botulinum toxin (BoNT) is One of the most potent toxins known to humans produced by Clostridium botulinum that has been used to treat several striated and smooth muscle disorders. Because the pathophysiology and the reason for patients' lack of response to PDE5I is insufficient smooth muscle relaxation and veno-occlusive disorder (VOD) , BTX-A may prove to be a viable treatment for this patient population due to its availability to facilitate long-acting cavernosal smooth muscle relaxation by in - Drug Tadalafil 5mg
Tadalafil is one of 5-phosphodiesterase inhibitors that used to treat male sexual function problems (impotence or erectile dysfunction-ED).
