Active clinical trials for "Prostatic Hyperplasia"

Spinal block is the most common anesthetic technique for transurethral resection of prostatectomy (TURP). Most patients undergoing TURP are elderly and frequently present with cardiopulmonary and endocrine diseases. Low-dose local anesthetic is commonly administer to limit the block level to minimize the hemodynamic changes. However, sometimes it may not provide an adequate level of sensory block. Thus, intrathecal additive is frequently administer with local anesthetic to improve analgesic effect. Dexmedetomidine(DXM), a selective 2-adrenoreceptor agonist, has been used in the epidural space in humans without any reports of neurological deficits. Previous clinical studies showed that intravenous dexmedetomidine administration prolonged the sensory and motor blocks of bupivacaine spinal analgesia. But clinical studies about the use of intrathecal DXM with local anesthesia in humans are scarce in the literature. Kanazi et al. found that 3μg DXM added to 12 mg spinal bupivacaine produced the significant short onset of sensory and motor block as well as significantly longer duration of sensory and motor block than bupivacaine. And Al-Mustafa et al. reported that intrathecal dexmedetomidine as an adjuvant to 12.5mg bupivacaine in spinal anesthesia has a dose dependant effect on the onset and regression of sensory and motor block. In our previous study, low-dose diluted bupivacaine 5 mg provided sufficient anesthetic level when opioid was added with local anesthetic. However, opioid-induced side effects, such as pruritus, nausea, or vomiting, could be an obstacle in common use. The aim of this study is to evaluate whether DXM-low-dose bupivacaine spinal anesthesia can provide the effective spinal anesthesia and postoperative analgesia with minimal side effect compare to the local anesthetic only group. This study was conducted in a randomized, double-blind, controlled fashion. Patients were randomly allocated to DXM group or Saline group. DMT group received hyperbaric bupivacaine 0.5% (1.2 ml) (6 mg) in dextrose 8% solution + DMT 0.3 ml (3 µg)-in total, bupivacaine 0.4% (1.5 ml) intrathecally and Saline group received hyperbaric bupivacaine 0.5% (1.2 ml) (6 mg) in dextrose 8% solution + normal saline 0.3 ml -in total, bupivacaine 0.4% (1.5 ml) intrathecally. After spinal block, the level of sensory block, defined as the dermatomal segment with loss of pain sensation to pin-prick with a 22 G hypodermic needle and cold sensation to alcohol swab was measured every 2 min after intrathecal injection. The investigators recorded the peak sensory block level, time to peak block level from intrathecal injection, blood pressure and heart rate, and analgesic supplementation during operation. The maximum motor block level was assessed according to the modified Bromage scale. During postoperative period, the frequency of analgesic requirement, time to the first analgesic request, and pain scores were evaluated by blind investigator.

Inflammation is reported as one of the most recent hypotheses to explain BPH. Recent published works pointed out that urine and serum markers could be used for detection of prostatic inflammation. The aim of the study is to assess the activity on inflammation biomarkers (serum and urine inflammation markers) of Permixon® 160 mg hard capsule and Tamsulosine Arrow LP in the treatment of urinary symptoms related to BPH. The potential links between serum and urinary markers of inflammation and BPH clinical symptoms at baseline and on treatment will be explored.

Purpose: To evaluate the efficacy of prostatic artery embolization (PAE) in patients with benign prostatic hyperplasia (BPH) and refractory lower urinary tract symptoms (LUTS) in decreasing the volume of the prostate gland. Participants: Study participants will be recruited from UNC Urology clinics as well as referring providers. We will include 15 men who are experiencing LUTS not controlled by medication with estimated prostate gland weight between 80 and 150 grams. Procedures (methods): Enrolled patients will undergo the standard work-up for a surgical prostate procedure. In addition, the patient's arteries will be evaluated with a pelvic CT angiogram. Then, patients will undergo prostatic artery embolization. Follow up visits will be scheduled at 1, 3, 6, and 12 months after the procedure. At the end of the follow-up period, if reduction in prostate gland size has made the patient eligible for transurethral therapy, they may proceed to such procedure or elect to undergo no further surgical procedure, depending on residual symptoms. Similarly, if insufficient gland size reduction has occurred, the patient may elect to pursue OP or no further procedure if they are no longer bothered by LUTS.

This study will be an open-label, randomized, single dose, three way crossover study in healthy male subjects. The aim of the study is to evaluate the pharmacokinetic parameters of two formulations of a fixed dose combination (FDC) capsule of dutasteride and tamsulosin hydrochloride (HCl) (0.5 milligram [mg]/0.2 mg) relative to co-administration of dutasteride 0.5 mg capsules and tamsulosin hydrochloride 0.2 mg tablets in both the fed and fasted states. Approximately 84 healthy adult male subjects will be enrolled into the study and split into two cohorts (fed and fasted), allowing for approximately 36 subjects to complete each cohort. Subjects from both cohorts will receive single oral doses in 3 treatment periods and be randomized to one of six different treatment sequences (ABC, ACB, BAC, BCA, CAB, CBA) wherein A= FDC1: Dutasteride and tamsulosin HCl (0.5 mg/0.2 mg), B= FDC2: Dutasteride and tamsulosin HCl (0.5 mg/0.2 mg), C= Co-administration of commercial formulations of dutasteride(0.5mg) and tamsulosin HCl (0.2mg). Each treatment period will be separated by a minimum 28 day washout period. Blood samples for pharmacokinetic analysis will be taken at regular intervals after dosing. Safety will be assessed by measurement of blood pressure, heart rate and review of adverse events.

This is an open-label, two-arm, one-sequence, cross-over study to evaluate the safety and pharmacokinetic interaction after oral concomitant administration of tadalafil and dutasteride in healthy male volunteers.

In this study, we investigate the changes of the expression of alpha adrenergic receptor in the prostate tissue during 2-yr medication period in the man with benign prostatic hyperplasia. And we also evaluate the efficacy and safety of 24 mo-treatment with doxazosin (4mg, 8mg)
