Article: Caverject

Caverject is an injection of a chemical called alprostadil, produced by Upjohn, used to treat impotence (also known as Erectile_dysfunction).

Caverject Sterile Powder contains alprostadil as the naturally occurring form of prostaglandin E1 (PGE1) and designated chemically as (11alpha, 13E, 15S)-11,15-dihydroxy-9-oxoprost-13-en-1-oic acid. The molecular weight is 354.49. Alprostadil is a white to off-white crystalline powder with a melting point between 115° and 116°C. Its solubility at 35°C is 8000 micrograms (mcg) per 100 milliliter double distilled water.

Caverject is administered via small-needle injection into an area of the penis known as the corpus cavernosum. It works by relaxing smooth muscle tissue which, in turn, enhances blood flow to the penis, creating an erection. The drug is indicated for the treatment of erectile dysfunction whether the cause is neurological, vascular, psychological or of mixed origin. Patients selected for treatment with Caverject receive initial injections from medically-trained personnel to determine optimum dosing. Caverject can be administered by the patient once he has been trained to self-inject.

Side Effects:
Caverject may cause mild pain, irritation or slight bleeding at the injection site. There is also a possibility to develop: tenderness or swelling of the penis, redness/lumps/unusual curving of the penis.
