Package leaflet: Information for the user Alprostadil Recordati 2 mg/g cream Alprostadil Read all of this leaflet carefully before you start using this medicine because it contains important information for you. After application of Alprostadil Recordati the onset of erection is within 5 to 30 minutes. You should not stop taking any prescription medications, unless told to do so by your doctor. What you need to know before you use Alprostadil Recordati Do not use Alprostadil Recordati – if you have underlying disorders such as drop in blood pressure when going from a lying/sitting to a standing position, history of a heart attack, and syncope (dizziness). Warnings and precautions Talk to your doctor or pharmacist before using Alprostadil Recordati if you have a history of the following local effects that have been observed with the use of Alprostadil Recordati: - Prolonged erections lasting >4 hours (priapism) - Symptomatic hypotension (dizziness) - Hepatic and/or renal insufficiency, a lowered dose due to impaired metabolism may be required - Fainting A condom should be used in the following situations: - Your partner is pregnant or breastfeeding - Your partner is of childbearing potential - To prevent sexually transmitted diseases - During oral sex and anal sex Only latex condoms have been studied. Other medicines and Alprostadil Recordati Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. The use of Alprostadil Recordati with other drugs used to treat Erectile Dysfunction have not been studied. Alprostadil Recordati has not been tested for use with penile implants or smooth muscle relaxants such as papaverine; drugs used to induce erections such as alpha blocking drugs (e. There is a risk of priapism (painful prolonged abnormal erection) when used in combination. Although not studied, it is possible that Alprostadil Recordati may have less of an effect when taken in combination with treatments for high blood pressure, decongestants and appetite suppressants. If you are taking drugs to prevent blood clots, do not take Alprostadil Recordati as there may be an increased risk for bleeding or blood found in the urine. In combination with high blood pressure medication, Alprostadil Recordati use may increase symptoms of dizziness and fainting, especially in the elderly. Pregnancy and breast-feeding and fertility There are no data on the use of Alprostadil Recordati in pregnant women. It is not known whether Alprostadil Recordati has an effect on human male fertility. Driving and using machines Alprostadil Recordati may make you feel dizzy or faint. How to use Alprostadil Recordati Always use this medicine exactly as your doctor has told you. Alprostadil Recordati is available in two dosage strengths of 200 and 300 mcg alprostadil in 100 mg of cream. Each Alprostadil Recordati AccuDose container is for single use only and should be properly discarded after use. Talk to your doctor who will instruct you on proper technique for administration and accomodation of your dose. Do not apply Alprostadil Recordati more than 2-3 times a week and only once per 24 hour period. Apply Alprostadil Recordati to the tip of the penis within 5 to 30 minutes prior to attempting intercourse by following the instructions below: 1. Remove the AccuDose container from the foil pouch by tearing fully down the seal from the middle of the top edge. Grasp the tip of the penis with one hand and gently manipulate to widen the opening of the penis. Note: if you are not circumcised, first retract and hold the foreskin back prior to widening the opening of the penis. Note: do not insert the tip of the AccuDose container in to the opening of the penis. Hold the penis in an upright position for approximately 30 seconds to allow the cream to penetrate. The amount of extra cream will vary depending on the patient and it is not unusual that half of the dose will remain at the edge of the opening. Do not use a second AccuDose to compensate for cream not expelled in to the opening of the penis. Any excess cream covering the opening may be rubbed gently in to the opening and skin surrounding the application site with the tip of a finger. Remember each Alprostadil Recordati dose is good for a single administration only. Replace the cap on the AccuDose container and place in the opened foil sachet, fold and discard in accordance with local requirements. Children and adolescents Alprostadil Recordati is not indicated for children or men below 18 years of age. If you use more Alprostadil Recordati than you should Overdose with Alprostadil Recordati requiring treatment has not been reported. Overdose with Alprostadil Recordati may result in a drop in blood pressure, fainting, dizziness, persistent pain in the penis, and possible prolonged erection lasting longer than 4 hours. If you have any further questions on the use of this medicine, ask your doctor or pharmacist. If you get a long-lasting erection of more than 4 hours, contact your doctor immediately. Your doctor may reduce your dose of Alprostadil Recordati and disontinue your treatment. Common side effects (may affect more than 1 in 10 patients): You: – mild to moderate local aching, burning or pain and redness of the penis, – rash, – genital pruritus, – penile oedema – inflammation of the glans penis (balanitis) – penile tingling, throbbing numbness, burning Your partner: -Mild vaginal burning or itching, vaginitis This effect may be due to the drug or to the act of vaginal penetration.

Therefore erectile dysfunction age 18 discount 12pc vpxl amex, if behavioral interventions do not result in a sustained improvement in patient satisfaction with the characteristics of voice erectile dysfunction treatment injection therapy discount vpxl 6pc online, then surgery may be considered erectile dysfunction treatment in bangalore buy genuine vpxl on line. Surgical considerations As previously stated erectile dysfunction in diabetes mellitus ppt buy vpxl 9pc low price, pitch of voice is related to overall vocal fold mass and the tension of the vocal fold while the patient is producing voice. However, even successful patients often complain of a sensation of vocal effort and/or fatigue at the end of the day. Therefore, surgeries have been designed to elevate pitch by either altering vocal fold tension, mass, or both. The tendency of biological structures to relax when artificially stretched or tensed represents a significant challenge to surgical approaches to voice modification. Furthermore, procedures which attempt to alter the tension by scarring the vibratory portion of the vocal fold, or reducing the overall vocal fold mass, risk inducing June 17, 2016 164 Guidelines for the Primary and Gender-Affirming Care of Transgender and Gender Nonbinary People negative alteration in the delicate tissue of the vocal folds, which must vibrate at high frequencies to produce normal vocal quality. Surgical attempts to elongate the vocal folds One of the earliest procedures reported for elevation of vocal pitch is a criothyroid approximation, or type 4 thyroplasty, initially developed in the 1970s. In this surgery, the vocal folds are placed under permanent increased tension, using sutures that approximate the front aspect of the thyroid cartilage to the cricoid ring. A year-long longitudinal report of 11 patients (only 1 of whom was transgender) who underwent this procedure showed initial promise immediately postop. This has led to proposed modifications to the originally described procedure, either by altering the method of suture placement,[25] or by scarifying the thyroid to the cricoid. Other attempts to permanently elongate the vocal folds to increase tension have resulted in similar outcomes. The theorized advantage is that the patient would be able to further modulate pitch. However, this has not been the outcome and the results are variable when the patients are followed long-term. Surgeries to reduce vocal fold mass and length In 1982, Donald et al [29] proposed surgery to reduce the size of the vocal folds, and create a web between the anterior portion of the vocal folds, by opening the larynx, removing the front third of the vocal folds and suturing the larynx closed. This surgery has the advantage of being able to be combined with procedures to reduce the prominence of the larynx in the neck. The procedure has been modified by other surgeons, and combined with shortening of the pharynx by bringing the larynx and the hyoid bone closure together. In a series of 94 patients (74 of whom were followed for approximately 1 year or more), these authors reported an average elevation of pitch from 139 Hz preoperatively to 196 Hz postoperatively. In addition, while the surgery is generally well tolerated, it does place the airway at risk and require an external incision in the anterior neck skin. Surgeries to increase tension by producing scar on the vocal folds As previously mentioned, vocal fold vibration rate, which determines the pitch of the voice, is affected by vocal fold mass (as the mass decreases, the vibration rate or pitch increases) and tension (as the tension increases the vibration and pitch increases). This has led surgeons to attempt to elevate pitch by increasing tension through scarring the surface of the vocal folds or scarring the front portion of the vocal folds together to shorten the portion available for vibration. The main advantage of these types of procedures is that they can be done through June 17, 2016 165 Guidelines for the Primary and Gender-Affirming Care of Transgender and Gender Nonbinary People the mouth without an incision in the neck, are well tolerated, and do no place the patient’s breathing at significant risk. The main disadvantage is that healing and scar production can be unpredictable and results variable. Variations on this procedure have replicated results in multiple small patient series from other centers. In all patients, there is a modest increase in degree of vocal roughness postoperatively, and this is more noticeable when the procedure is performed in patients over 50 years of age. The procedure can also be repeated if healing does not result in as much scar as desired, and can be performed in patients who have failed other types of surgery. Voice masculinization Far fewer transgender males present for voice evaluation and treatment than transgender females. This may be related to the reduction in pitch that transgender males experience as a result of hormone therapy. Following response to this treatment, it is reported that about 75% of trans men are identified as male by telephone. The perceived masculinity of voice is related not only to pitch but also to the proximity of the habitual speaking pitch to the pitch floor, or lowest pitch. These changes in resonance are further supported by data showing a change in formant frequencies June 17, 2016 166 Guidelines for the Primary and Gender-Affirming Care of Transgender and Gender Nonbinary People (the acoustic correlate of resonance) during the first year of hormone treatment in conjunction with behavioral intervention. However, transgender women who were misidentified as male had fewer upward and more downward intonation patterns than females and transgender females who were correctly identified. However, if increasing breathiness [9,17] and using lower vocal intensity [13,17] contributes to voice feminization, it may be considered that reducing breathiness and avoiding a soft voice may be perceived as more masculine. Behavioral intervention While pitch is primarily addressed through hormone therapy and secondarily by voice therapy, the other components of voice production are primarily addressed through behavioral voice therapy. Flow phonation and resonant voice therapy are two common voice therapy techniques. Flow phonation targets the balanced exhalation of airflow during voice production using respiration as the power source to achieve vocal efficiency. Resonant voice therapy focuses on achieving easy phonation while experiencing the energy or vibration of sound in the oral cavity. Some transmasculine spectrum people seek only some voice masculinization, and desire flexibility with their voice and communication. With this in mind, voice therapy should be patient specific and physiologically based to achieve patient and therapy goals in a vocally efficient and safe manner. Effects of testosterone hormone therapy on voice 90% of trans men will achieve acceptable voice results, lowering of pitch in to a gender neutral or male range, after 4 to 5 months of taking exogenous androgens. Surgical consideration As hormonal therapies and behavioral therapies are effective in helping 90% of transgender men achieve acceptable voice, surgical intervention is rarely indicated in this group. If needed, however, relaxation thyroplasty, designed to reduce the tension of the vocal folds can be performed. This same surgery is used in male patients with inappropriately elevated pitch and results in a reduction of pitch if performed in the original method [45] and an even greater reduction if modified as described by other authors. Typical pitch reduction is in the range of 100 Hz and usually results in the patient attaining an acceptable male vocal pitch. However, as the vocal cord tension is less controllable after the intervention, the voice is often perceived as more rough and with less volume.

Theoretically, if blood flow to the penis can be maintained the tissue may be less prone to scarring and shrinkage. The most common form of penile rehabilitation involves use of oral medications and/or devices to help stimulate blood flow and erection. The evidence is mixed on how well these interventions work but there is little risk of harm from using treatments to help erections after surgery. Staying engaged in a program of rehabilitation can help men stay committed to recovery of their sexual quality of life, and use of the medications can help to facilitate sexual activity during the recovery process. Most often, a step-wise approach will be taken with the least intrusive option selected first. There are a number of medical options that can help men attain and maintain a rigid penis for sexual activity. While a step-wise approach from simple to more complicated treatments is appropriate for most patients some patients may choose to “skip” or avoid some of the available treatment options. In the end, the goal is always to re-establish sexual intimacy and pleasure, which can be achieved in a number of Figure 2: Nerves of the Pelvis. Each individual man needs to decide of the prostate to the cavernous nerves (nerves that allow erection) on which priorities and what treatments are acceptable for him. Men who are unable to achieve a rigid erection may still enjoy cuddling, genital caressing, and/ or oral sex. With a supportive partner, patience, and a willingness to explore different means of being sexual, most men are able to achieve sexual satisfaction and even orgasm, regardless of whether they can obtain an erection sufficient for penetrative sex. A good way to resume your sex life is to use a gradual, progressive approach and to make sure that you and your partner feel comfortable at every step. Sensual, mutually pleasuring activities with no performance goal can allow you to be intimate in a relaxed way. A man and his partner may need to redefine what is important about their sexual relationship after cancer treatment. Although some may see kissing, caressing, and/or oral sex as simply foreplay in preparation for intercourse, arousing each other and even reaching orgasm without intercourse can be an important component of intimacy and a common way to share physical pleasure and emotional closeness without the need for a rigid erection. Your sex life should be based on what you and your partner mutually define as sexually satisfying and pleasurable; this may or may not include penile penetration. Certainly it is an important part of sexual life for many couples and there are a number of medical options to help men achieve a rigid erection for penetration. However, in situations where a man cannot achieve or maintain an erection it is important to focus on mutual pleasure and intimacy, not erectile hardness. If you would like access to sexual or marriage counseling/advice, please ask your physician for a referral. The American Association of Sex Educators, Counselors, and Therapists also maintains a website that contains valuable information on sexual wellness (www. Following sexual stimulation, a compound called nitric oxide is released at the nerve terminals causing relaxation of penile smooth muscles. In the absence of sexual stimulation or in cases where there has been injury to the cavernous nerves, nitric oxide production may be minimal and these medications will have little effect on the penis. These oral agents must be followed by sexual stimulation in order to achieve the desired erection. A patient’s response to these medications may reach from 70 to 80 percent, depending on patient age, health, etc. Oral medications have been used as a form of penile rehabilitation for men who have undergone radical prostatectomy, radiation therapy, and hormone therapy, with the theory being that enhanced blood flow may help to spur recovery of spontaneous erections by keeping the penile tissues supplied with blood. Aside from potential long term benefits, enhancement of erectile response from use of these medications may help to facilitate sexual encounters and maintain intimacy while a man is in recovery from prostate cancer treatment. Viagra and Levitra remain in the blood stream and can help men achieve erections for about 6–8 hours. Stendra stays in the circulation for a period of time somewhere between the Cialis and the other drugs. Men at risk for heart attack or stroke should consult with their physicians before engaging in sexual activity as this can be a strain on the heart. Men who are taking nitrate medicines should not take any of these medications as the combination can cause a severe drop in blood pressure that could be life threatening. Caution should also be exercised in men who are taking alpha blocker medications (commonly used for prostate problems and/or for high blood pressure). Do not take Viagra after a high-fat meal Viagra • If you do not achieve an erection with stimulation, you can increase the dosage of medications used the next time sexual activity is planned. After surgery, most men require doses of 100mg of Viagra • Take 10 mg of Levitra one hour before you are ready to engage in sexual activity Levitra • Levitra works best 30 minutes to four hours after taking the pill • If you do not achieve an erection, you may need to increase the dosage to 20 mg. After surgery, most men require doses of 20 mg of Levitra Cialis • Take 10 mg of Cialis up to 36 hours before you are ready to engage in sexual activity • Cialis can be taken after meals • If you do not achieve an erection on 10 mg, increase the dosage to 20 mg. After surgery, most men require doses of 20 mg of Cialis Standra • Take 100 mg of Stendra one half hour before you are ready to engage in sexual activity • Stendra works best 30 minutes to four hours after taking the pill • If you do not achieve an erection, you may need to increase the dosage to 200 mg. This is typically accomplished by administering regular doses of medications like Viagra, Levitra, Stendra, or Cialis without necessarily planning to have sex; in some cases physical exercises and/or a vacuum erection device may also be used. The decision of whether or not to take medications as part of penile rehabilitation should be made taking into consideration some of the controversies and also the cost of medication over time. Regardless of their use in rehabilitation, erection medications can be very helpful in helping men achieve erection after prostate cancer treatment. We also encourage men to maintain intimacy with their sexual partner during the recovery process; the emotional rehabilitation and maintenance is as important as the physical recovery. Take Viagra 100mg, Levitra 20mg, or Cialis 20 mg at least weekly with sexual stimulation Evaluation of sexual function • If you have a response to oral medications (penile fullness or 8-12 weeks after surgery erection), continue Viagra 50mg or Levitra 10 mg daily 4–5 days/ week and 100mg Viagra or 20 mg Levitra 2–3x per week. Alternatively, use Cialis 20mg 3x/week • If no or marginal response to oral medications, begin penile injections and/or vacuum erection instruction. Consider beginning injections 2–3 times per week or vacuum erection use 2–3 times per week. Continue 50mg Viagra or 10 mg Levitra 10mg 4–5 days per week on days when not using injections Evaluation of sexual function • If no spontaneous erections after 1 year and unsatisfied with 12 months after surgery penile injections or vacuum erection device, consider alternative interventions for erectile dysfunction. The role and structure of a postradical prostatectomy penile rehabilitation program. While many men object to the notion of an injection into the penis, the needle typically used for these injections is smaller than a human hair and oftentimes not even painful. The most commonly used agents include prostaglandin E1 or a combination of different drugs that cause increased blood flow (e. Combinations of different medicines may be more effective than single drugs alone and may also carry lower risks for side effects. Men must have appropriate training and education before beginning penile injection therapy. The goal of the injection medication is to achieve an erection that is sustained for sexual intercourse, but not prolonged or painful. The injections must be given in proper amounts with the appropriate technique to minimize the risk of scarring in the penis or priapism, a prolonged and painful erection which may cause permanent damage. The medication is injected into the side of the penis into the corpora cavernosa, the paired erectile bodies of the penile shaft. After choosing the proper site to inject, the skin should be cleaned with an alcohol pad. The needle is inserted perpendicular to the penile shaft so as to enter the right spot; it is important that the medicine be administered to the inside of the corporal body, not just underneath the skin. After the medication is injected, the needle is withdrawn and firm pressure is applied to the site to reduce the risk of bleeding or bruising; men who take aspirin or other blood thinner should hold pressure for a bit longer. Some experts recommend that men stand for at least 10 minutes after injection to enhance penile blood flow. Men who are interested in injections but unable to administer the shot themselves may enlist the aid of their partner. Alternatively, an auto-injector is a spring-loaded device that inserts the needle into the penis very quickly, minimizing psychological “hesitancy. Improper injection and any subsequent scarring can lead to penile curvature and nodules in the penis, so it is important to get the proper training before beginning injection therapy. Most men and their partners find that injection therapy is easy to perform and are very pleased with the results. Some patients who have been treated for prostate or bladder cancer may benefit from using injection therapy early on after surgery; as their erectile function gradually recovers such men may wish to then switch to oral agents. After cleaning with an alcohol swab, insert needle into side of penis and inject medication. The side of the penis is cleaned with an alcohol swab and the injector placed against the penis.
Both dutasteride and finasteride are known to erectile dysfunction drugs don't work purchase vpxl overnight delivery increase serum testosterone by 10%–30% from base- line top erectile dysfunction doctors new york purchase discount vpxl line, with a greater increase in men with lower baseline levels (which could be a regression-to-the- mean phenomenon) (203 impotence age 40 purchase generic vpxl canada,269–271) erectile dysfunction shakes menu vpxl 6pc without a prescription. Finasteride and dutasteride are generally well tolerated, with the most prevalent adverse events being sexual function–related, such as impotence, decreased libido, and abnormal or decreased volume of ejaculation. However, these side effects are rare compared to those associated with traditional anti- androgen treatment, typically appearing in the first year of treatment in 5%–10% of patients.

In the untreated control group, hematuria recurred in 17 patients (63%) within a year, but in only 4 patients (14%) in the finasteride group, which was a statistically significant difference (p<0. Surgery was required for bleeding in 7 control patients (26%), while no patient on finasteride required surgery. Vascular endothelial growth factor expression was examined by immunohistochemistry. Many of these studies suffered from methodological shortcomings in terms of the measurement of blood loss, standardization, and the definitions of meaningful endpoint (e. Microvessel density was calculated by immunostaining and light microscopy of the prostatic chips. Two large placebo-controlled trials using finaste- ride and dutasteride consistently showed a reduction in the period prevalence of prostate cancer, by approximately 23%–25% (235,297). The committee does not make a formal recommendation and refers to other guidelines from authoritative bodies (Grade D). Cyclic nucleotides are synthesized from the corresponding nucleoside triphosphates by the activity of adenylyl and guanylyl cyclases. This cascade leads to a reduction in cytosolic Ca2+ and, finally, to smooth muscle relaxation. Male Lower Urinary Tract Symptoms: Medical Management and New Therapeutic Targets 471 Some of these isoenzyme families consist of more than one gene, and some genes are alternatively spliced so that more than 50 isoenzymes or variants have been identified. The consequence is a drop in cytosolic Ca2+ concentrations, and relaxation of the smooth muscle. Together, these studies demon- strate reliable strength of association among study consistency, dose-response effect, and temporality (although further studies are needed). The studies also consistently account for alternative explana- tions of bias, confounding, and randomness through the use of well-powered multivariate analyses. Risk factors for one are often risk factors for another, and second messenger cascades ultimately leading to smooth muscle contraction and relaxation for either prostatic/bladder neck tissue or erectile tissue may be shared. The arrows demonstrate the interplay of the four theories, as they share many common pathways and etiologies. Note that the risk factors for one mechanism are often similar to those for another.

Sildenafil (50 mg) or placebo was administered daily, either before bedtime or sexual activity. After 2 weeks, the sildenafil dose was increased to 100 mg daily, being well tolerated by 90% of patients. A total of 247 men were randomized, and 225 completed the 8-week intention-to-treat study. Patients were evaluated after 6 weeks of treatment, and the tadalafil dose was increased to 20 mg daily. Similar results were reported in a phase 2 dose-ranging randomized double-blind, placebo-controlled, parallel-group, multinational study, in which 1,058 men were randomly assigned to placebo or one of four tadalafil daily dosing regimens (2. The Qmax of the tadalfil treatment group was not significantly different from that of the placebo treatment group for any treatment arm. Randomization (baseline) followed a 4-week placebo lead-in; changes from baseline were assessed via analysis of covariance and compared to placebo. Overall, tadalafil was well tolerated, with no clinically adverse changes in orthostatic vital signs or uroflowmetry parameters. Following screening and washout, if needed, subjects completed a 4-week placebo run-in before randomization to placebo (n=172), tadalafil 5 mg (n=171), or tamsulosin 0. This study was limited in not being powered to directly compare tadalafil versus tamsulosin (320). Table 45 summarizes the key efficacy results of the study, and Table 46 summarizes the adverse events data.. In that study, 427 men who completed the 12-week, placebo-controlled, dose-finding study assessing once-daily tadalafil (2. To answer the question of safety, a stratified enrollment was done, such that one third of each treatment arm were not obstructed, one third were equivocal, and one third were obstructed based on the Abrams-Griffiths nomogram (326). All assessments, including standardized invasive pressure-flow studies with central reader, were done at baseline and repeated at 12 weeks. The only study in which a statistically significant improvement from baseline was achieved was the tadalafil direct comparator trial versus tamsulosin and placebo (320). Male Lower Urinary Tract Symptoms: Medical Management and New Therapeutic Targets 491 8. The studies, however, lacked placebo control, and outcome assessment was inconsistent. Another study compared the efficacy of terazosin, finasteride, and a combination of both in 195 men with enlarged prostate glands (335). All patients–those receiving terazosin (n=64), finasteride (n=65), or combination therapy (n=66)–were well matched at baseline. The authors provided information on study patients with prostates of 40 mL or larger (n=33). In the finasteride group, these patients had greater improvement in symptom score compared with those with prostates <40 mL (n=32) (?6. Although this study also lacked a placebo group, it differed from the previous studies in that it enrolled patients with particularly large prostates (average: 46. This random- ized, double-blind, multicentre trial compared the effects of 6 months of therapy with a sustained- release formulation of the alpha1-blocker alfuzosin, 5 mg twice daily (n=358); finasteride, 5 mg once daily (n=344); or both drugs in combination (n=349) (336). Patients in the alfuzosin, finasteride, and combination therapy groups had decreases from baseline symptom score of 6. The difference in score reduction was signifi- cant between the alfuzosin and finasteride groups (p=0. Prostate-specific antigen levels also decreased significantly in these two treatment arms, whereas no change was observed in the alfuzosin arm. A total of 1,229 men were randomized to receive placebo (n=305); finas- teride, 5 mg/day (n=10); terazosin at a forced titration to 10 mg/day, with permission to reduce the dosage to 5 mg/day in the event of an adverse event (n=305); or a combination of finasteride and terazosin (n=309).
