Described are implantable devices and methods for treating various disorders of the pelvic floor by means of electrical stimulation of the pudendal or other nerves, and optional means for delivering drugs in association therewith. A method of precisely positioning and implanting a medical electrical lead so as to provide optimal stimulation of the pudendal nerve or a portion thereof is also described. Placement of a stimulation lead next to or on the pudendal nerve may be performed using conventional prior art techniques through gross anatomical positioning, but usually does not result in truly optimal lead placement. One method of the present invention utilizes neurophysiological monitoring to assess the evoked responses of the pudendal nerve, and thereby provide a method for determining the optimal stimulation site. Additionally, one or more electrical stimulation signals are applied, and optionally one or more drugs are infused, injected or otherwise administered, to appropriate portions of a patient's pelvic floor and pudendal nerve or portions thereof in an amount and manner effective to treat a number of disorders, including, but not limited to, urinary and / or fecal voiding dysfunctions such as constipation, incontinence disorders such as urge frequency and urinary retention disorders, sexual dysfunctions such as orgasmic and erectile dysfunction, pelvic pain, prostatitis, prostatalgia and prostatodynia.

A once-a-day oral milnacipran modified release formulation has been developed. The formulation comprises an extended release dosage unit (optionally containing the immediate release portion) coated with delayed release coating. The milnacipran composition, when administered orally, first passes through the stomach releasing from zero to less than 10% of the total milnacipran dose and then enters the intestines where drug is released slowly over an extended period of time. The release profile is characterized by a 0.05-4 hours lag time period during which less than 10% of the total milnacipran dose is released followed by a slow or extended release of the remaining drug over a defined period of time. The composition provides in vivo drug plasma levels characterized by Tmax at 4-10 hours and an approximately linear drop-off thereafter and Cmax below 3000 ng / ml, preferably below 2000 ng / ml, and most preferably below 1000 ng / ml. The composition allows milnacipran to be delivered over approximately 24 hours, when administered to a patient in need, resulting in diminished incidence or decreased intensity of common milnacipran side effects such as sleep disturbance, nausea, vomiting, headache, tremulousness, anxiety, panic attacks, palpitations, urinary retention, orthostatic hypotension, diaphoresis, chest pain, rash, weight gain, back pain, constipation, vertigo, increased sweating, agitation, hot flushes, tremors, fatigue, somnolence, dyspepsia, dysoria, nervousness, dry mouth, abdominal pain, irritability, and insomnia.
