In order to characterize inverse agonism at alpha1B-adrenoceptors, we have compared the concentration-response relationships of several quinazoline and non-quinazoline alpha1-adrenoceptor antagonists at cloned hamster wild-type (WT) alpha1B-adrenoceptors and a constitutively active mutant (CAM) thereof upon stable expression in Rat-1 fibroblasts. Receptor activation or inhibition thereof was assessed as [3H]inositol phosphate (IP) accumulation. Quinazoline (alfuzosin, doxazosin, prazosin, terazosin) and non-quinazoline alpha1-adrenoceptor antagonists (BE 2254, SB 216,469, tamsulosin) concentration-dependently inhibited phenylephrine-stimulated IP formation at both WT and CAM with Ki values similar to those previously found in radioligand binding studies. At CAM in the absence of phenylephrine, the quinazolines produced concentration-dependent inhibition of basal IP formation; the maximum inhibition was approximately 55%, and the corresponding EC50 values were slightly smaller than the Ki values. In contrast, BE 2254 produced much less inhibition of basal IP formation, SB 216,469 was close to being a neutral antagonist, and tamsulosin even weakly stimulated IP formation. The inhibitory effects of the quinazolines and BE 2254 as well as the stimulatory effect of tamsulosin were equally blocked by SB 216,469 at CAM. At WT in the absence of phenylephrine, tamsulosin did not cause significant stimulation and none of the other compounds caused significant inhibition of basal IP formation. We conclude that alpha1-adrenoceptor antagonsits with a quinazoline structure exhibit greater efficacy as inverse agonists than those without.

hytrin dosing

Terazosin, a new long-acting selective alpha 1-receptor antagonist, was studied in a crossover trial to assess the effect of age on oral and intravenous pharmacokinetics. Thirty healthy male and female volunteers between the ages of 23 and 75 years received 1-mg oral and intravenous doses of terazosin. For both routes of administration, the only pharmacokinetic variables significantly correlated with age were terminal elimination rate constant and the area under the plasma concentration-time curve (AUC). However, the differences in half-life and AUC between the youngest and oldest subjects were modest and not of practical clinical significance. There was no evidence of an enhanced pharmacologic or toxic effect in older subjects. From these data, we conclude that the dosage of terazosin does not need to be adjusted on the basis of age alone; the dose of terazosin is titrated in all patients to the lowest effective dose that is well tolerated.

The quinazoline family of alpha1-blockers (prazosin, doxazosin, and terazosin) induce apoptosis of prostate cells through an alpha1-adrenoceptor-independent mechanism. The objective of this study was to gain insight into the non-adrenergic, apoptotic mechanism of action of doxazosin in the prostate and the induction of anoikis by doxazosin. Primary cultures of benign prostate stromal and epithelial cells and the LNCaP (androgen sensitive) and PC-3 (androgen insensitive) prostate carcinoma cell lines were treated with doxazosin (0-50 microM). The effects of doxazosin on cell morphology, caspase-3 activity, and the expression levels of focal adhesion kinase (FAK) and integrin-linked kinase (ILK) were examined. Doxazosin induced changes in morphology consistent with anoikis in both benign and cancerous prostatic cells and increased caspase-3 activity. The effects were similar comparing benign cells (which express alpha1-adrenoceptors) and cancer cells (which do not express alpha1-adrenoceptors), but were more robust in benign cells. Norepinephrine had no effect on doxazosin-induced cell morphology or caspase-3 activity. Treatment of PC-3 cells with doxazosin significantly reduced the protein levels of FAK but did not significantly affect the levels of ILK. These findings suggest that doxazosin induces apoptosis and anoikis of prostate cancer cells by a mechanism of action that is alpha1-adrenoceptor independent. The apoptosis of cancer cells induced by doxazosin counteracts cell proliferation and may have the potential of retarding or reversing prostate cancer cell growth.

The efficacy and safety of terazosin were compared with those of other antihypertensive drugs in three parallel-group, randomized, double-blind studies in which 133 patients with mild to moderate hypertension participated. In two studies, terazosin monotherapy was compared with placebo and prazosin (study M79-073), or with hydrochlorothiazide (study M80-012). In a third study (M80-013), the combination of terazosin plus hydrochlorothiazide was compared with the combination of prazosin plus hydrochlorothiazide. Doses of study medications were administered twice daily and were increased at weekly intervals until the average supine diastolic blood pressure was 90 mm Hg or less, with a decrease from baseline of at least 10 mm Hg, or until the maximum specified dosage of a given study drug was reached. In general, all active treatments resulted in significant decreases from baseline in supine and standing blood pressures. There was no significant difference between terazosin- and prazosin-treated patients for changes from baseline to the final visit in supine or standing blood pressure measurements (study M79-073). Hydrochlorothiazide had a significantly greater effect on supine diastolic blood pressure when compared with terazosin (study M80-012). Otherwise, there were no significant differences between active treatment groups. Overall, no regimen caused clinically important changes in pulse rates, body weights, laboratory test results, physical examinations, or electrocardiograms. The incidence of side effects was approximately the same for all drugs; the most common side effects were headache, dizziness, malaise, asthenia, and nasal congestion. The results of these studies suggest that terazosin exhibits antihypertensive activity that is quantitatively similar to that of prazosin in patients with mild to moderate hypertension, and that a dose of 1 to 10 mg twice daily is well tolerated.

Cystometry was performed in conscious female rats recording bladder volume capacity (BVC), evaluated as the amount of saline infused between two voiding cycles, and micturition volume (MV). Changes in frequency and amplitude of spontaneous non-voiding bladder contractions (NVC) were also recorded. The effects of the intravenous administration of suramin (100 mg/kg), BMY 7378 (1 mg/kg), and terazosin (0.3 mg/kg) on NVC, BVC and MV were evaluated in obstructed rats with bladder infusion of saline. The effects of infravesical infusion of suramin (3-10 micromol/L), terazosin (1 micromol/L) and BMY 7378 (10 micromol/L) were also evaluated and compared with values observed in control rats during saline infusion into the bladder.

Current guidelines recommend α1-adrenoreceptor blockers (A1Bs) for treating lower urinary tract symptoms suggestive of benign prostatic hyperplasia, but their adverse effects can be problematic. In this study, reports submitted to the US Food and Drug Administration Adverse Event Reporting System (FAERS) between 1997 and 2011 were reviewed to assess the safety profiles of A1Bs.

hytrin tablets uses

For various reasons, the alpha 1-receptor blocker prazosin has been used infrequently as initial therapy for hypertension. The introduction of additional agents of this class with properties different from prazosin provides slower onset of action, which should reduce the degree of first-dose and postural hypotension and a longer duration of action, which allows for once-a-day dosage. A summary of the published data on efficacy, side effects, and special properties of this class of agents indicates that they will probably be used more extensively, particularly because of their ability to improve lipid and glucose-insulin metabolism.

In a previous study, we showed that electroacupuncture (EA) applied to the SI-6 point on the contralateral forelimb produces long-lasting and powerful analgesia in pain caused by ankle sprain in a rat model. To investigate the underlying mechanism of EA analgesia, the present study tested the effects of various antagonists on known endogenous analgesic systems in this model. Ankle sprain was induced in anesthetized rats by overextending their right ankle with repeated forceful plantar flexion and inversion of the foot. When rats developed pain behaviors (a reduction in weight-bearing of the affected hind limb), EA was applied to the SI-6 point on the contralateral forelimb for 30 min under halothane anesthesia. EA significantly improved the weight-bearing capacity of the affected hind limb for 2h, suggesting an analgesic effect. The alpha-adrenoceptor antagonist phentolamine (2mg/kg, i.p. or 30 microg, i.t.) completely blocked the EA-induced analgesia, whereas naloxone (1mg/kg, i.p.) failed to block the effect. These results suggest that EA-induced analgesia is mediated by alpha-adrenoceptor mechanisms. Further experiments showed that intrathecal administration of yohimbine, an alpha(2)-adrenergic antagonist, reduced the EA-induced analgesia in a dose-dependent manner, whereas terazosin, an alpha(1)-adrenergic antagonist, did not produce any effect. These data suggest that the analgesic effect of EA in ankle sprain pain is, at least in part, mediated by spinal alpha(2)-adrenoceptor mechanisms.

The concept of a tonic drive activating respiratory muscle in wakefulness but not sleep has been an important and enduring notion in respiratory medicine, not least because it is useful in modeling sleep effects on breathing and understanding the pathogenesis of sleep-related breathing disorders such as obstructive sleep apnea. However, a neurotransmitter substrate mediating respiratory muscle activation across sleep-wake states has not been identified.

Chi-square test was used to determine the statistical significance of resolution of upper tract stasis. Student's t test for 2-paired samples was used to evaluate whether urodynamic parameters differed significantly before and after treatment with alpha1-blockers.

hytrin drug information

Clinical trials are currently underway to evaluate the efficacy of terazosin for the treatment of symptomatic benign prostatic hyperplasia (BPH). Terazosin is a potent and selective alpha 1 adrenergic blocking agent structurally similar to prazosin. The alpha adrenergic binding properties of terazosin were studied in human prostate adenomas and canine brains using radioligand receptor binding methods. Saturation analyses were performed at varying concentrations of [125I]-Heat and [3H]rauwolscine [( 3H]Ra) in human prostate adenomas and canine brains. The binding of [125I]-Heat and [3H]Ra in the human prostates and canine brains was consistently saturable and of high affinity. The equilibrium dissociation constant (Kd) for [125I]-Heat binding in the canine brains and human prostate adenomas was 84.4 +/- 4.3 pM and 65.4 +/- 19.2 pM, respectively (p greater than 0.05). The (Kd) for [3H]Ra binding in the human prostate adenomas and canine brains was 1.21 +/- 0.23 nM and 1.52 +/- 0.28 nM, respectively (p greater than 0.05). The density of alpha 1 (0.37 +/- 0.15 fmol/mg. wet wt.) and alpha 2 (0.29 +/- 0.09 fmol/mg. wet wt. adrenergic binding sites in the human adenomas were similar (p greater than 0.05). The IC50 corrected (IC50 corr) of terazosin for [125I]-Heat and [3H]Ra binding sites in the human prostate was 2.5 nM and 1.0 micron., respectively. The IC50 corr of terazosin for [125I]-Heat and [3H]Ra binding sites in the canine brain was 2.0 nM and 0.8 microM, respectively. The competitive binding assays indicate that terazosin binds selectively to alpha 1 adrenergic binding sites in the human prostate and canine brain.

Drugs were administered transdermally by iontophoresis in the forearm of 20 healthy participants. Phenylephrine and clonidine were administered at sites pretreated with the relevant antagonist (terazosin and rauwolscine), and at additional untreated sites and sites pretreated with saline. To enhance the contrast between sites, the forearm was heated to 42 degrees C before flow was measured with the laser Doppler technique.

The purpose of this investigation was to determine the effectiveness of alpha-1 blockade in the treatment of bladder outlet obstruction in the spinal cord injured (SCI) patient. We evaluated terazosin, a selective alpha-1 blocker, in 15 normotensive SCI patients. Detrusor-external sphincter dyssynergia (DESD), without obstruction of the bladder neck or prostate, was documented in all patients using video-urodynamic evaluation. Urodynamic testing was performed both before and during treatment with terazosin (5 mg nightly). Voiding pressure before and during terazosin therapy averaged 92 +/- 17 and 88 +/- 27 cm H2O, respectively (p = 0.48). After subsequent external sphincterotomy or sphincter stent placement, the voiding pressure was reduced to 38 +/- 15 cm H2O (p < 0.001). Nine other patients suffered from persistent difficulty voiding after previous sphincterotomy. Each was subsequently treated with oral terazosin. In five patients who improved with this treatment, urodynamic parameters demonstrated obstruction only at the bladder neck, with no evidence of obstruction at the level of the external sphincter. The four patients who failed to improve were documented to have an open bladder neck but obstruction at the level of the external sphincter. Our data show that alpha-1 sympathetic blockade has no effect on external sphincter function and does not significantly relieve functional obstruction caused by DESD. It was also noted that terazosin is helpful in diagnosing and treating internal sphincter (bladder neck and prostate) obstruction especially in patients who have persistent difficulty voiding after external sphincterotomy.

An older method for terazosin was reworked in order to reduce the analysis time from 90min (2×45min) to below 5min. The method in European Pharmacopoeia (Ph.Eur.) investigates the specified impurities separately. The reason of the different methods is that the retention of two impurities is buy hytrin not adequate in reversed phase, not even with 100% water. Therefore ion-pair-chromatography has to be applied and since that two impurities absorb at low UV-wavelength they had to be analyzed by different method than the other specified impurities. In our new method we could improve the retention with pH elevation using a new type of stationary phases available for high pH applications. Also a detection wavelength could be selected that is appropriate for the detection and quantification of all impurities. The method development is the bottleneck of liquid chromatography even today, when more and more fast chromatographic systems are used. Expert knowledge with intelligent programs is available to reduce the time of method development and offer extra information about the robustness of the separation. Design of Experiments (DoE) for simultaneous optimization of gradient time (tG), temperature (T) and ternary eluent composition (tC) requires 12 experiments. A good alternative way to identify a certain peak in different chromatograms is the molecular mass of the compound, due to its high specificity. Liquid Chromatography-Mass Spectrometry (LC-MS) is now a routine technique and increasingly available in laboratories. In our experiment for the resolution- and retention modeling the DryLab4 method development software (Version 4.2) was used. In recent versions of the software the use of (m/z)-MS-data is possible along the UV-peak-area-tracking technology. The modelled and measured chromatograms showed excellent correlations. The average retention time deviations were ca. 0.5s and there was no difference between the predicted and measured Rs,crit -values.

The venoarteriolar response causes vasoconstriction to skin and muscle via local mechanisms secondary to venous congestion. The purpose of this project was to investigate whether this response occurs through alpha-adrenergic mechanisms. In supine individuals, forearm skin blood flow was monitored via laser-Doppler flowmetry over sites following local administration of terazosin (alpha(1)-antagonist), yohimbine (alpha(2)-antagonist), phentolamine (non-selective alpha-antagonist) and bretylium tosylate (inhibits neurotransmission of adrenergic nerves) via intradermal microdialysis or intradermal injection. In addition, skin blood flow was monitored over an area of forearm skin that was locally anaesthetized via application of EMLA (2.5 % lidocaine (lignocaine) and 2.5 % prilocaine) cream. Skin blood flow was also monitored over adjacent sites that received the vehicle for the specified drug. Each trial was performed on a minimum of seven subjects and on separate days. The venoarteriolar response was engaged by lowering the subject's arm from heart level such that the sites of skin blood flow measurement were 34 +/- 1 cm below the heart. The arm remained in this position for 2 min. Selective and non-selective alpha-adrenoceptor antagonism and presynaptic inhibition of adrenergic neurotransmission did not abolish the venoarteriolar response. However, local anaesthesia blocked the venoarteriolar buy hytrin response without altering alpha-adrenergic mediated vasoconstriction. These data suggest that the venoarteriolar response does not occur through adrenergic mechanisms as previously reported. Rather, the venoarteriolar response may due to myogenic mechanisms associated with changes in vascular pressure or is mediated by a non-adrenergic, but neurally mediated, local mechanism.

The safety of terazosin, an effective agent for the treatment of hypertension, was assessed by analyzing data from 1,006 hypertensive patients who were enrolled in short-term and/or long-term studies. The total experience with terazosin in this article represents 422.5 patient-years. Changes in pulse rate measurements from pretreatment to posttreatment were not significantly different between the terazosin- and placebo-treated patients (-1.0 beat per minute for the terazosin group and -1.0 beat per minute for the placebo group, in the supine position). Dizziness, headache, and asthenia were the most commonly reported adverse experiences buy hytrin among all terazosin-treated patients, although the incidence of headache in placebo-controlled trials was not significantly different between the terazosin and placebo groups. As a whole, patients receiving terazosin had a tendency to gain small amounts of weight (2 pounds). In addition, there was a trend for slight decreases in hemoglobin, hematocrit, white blood cell count, total protein, and albumin levels in those patients who received terazosin, suggesting hemodilution. Overall, terazosin was shown to be safe in patients with mild to moderate essential hypertension.

The patients were randomly divided into 3 buy hytrin groups: group 1 (34 patients) received tamsulosin, group 2 (35 patients) received terazosin, and group 3 (38 patients) received placebo. All patients were diagnosed by kidney-ureter-bladder X-ray, abdominal ultrasonography and intravenous urography. The number of colic episodes, lower urinary tract symptoms, analgesic dosage and days for spontaneous passage of the stones through the ureter were recorded by diary. Statistical analyses were performed using ANOVA, the chi(2) test, Fisher's exact test and the non-parametric Wilcoxon 2-sample t test.

Although the general approach to management of a sufficient degree of benign prostatic hyperplasia in the past was surgical intervention (transurethral resection of the prostate), the current availability of effective pharmacologic therapy has changed the initial management strategy. At present, two types of drugs are available for treatment of prostatism: (1) selective alpha-adrenergic blocking agents (terazosin, doxazosin, and tamsulosin) and (2) an inhibitor of the 5 alpha-reductase enzyme (finasteride). Pharmacologic blockade of the alpha(1)-adrenoceptors is thought to result in relaxation of the smooth muscle in the prostate and bladder neck, which reduces urethral resistance, improves voiding function, and minimizes the symptoms of prostatism. These effects may be noted by the patient within several weeks after initiation of treatment buy hytrin . The mechanism of action of finasteride is a blocking of the conversion of testosterone to dihydrotestosterone and an associated volume shrinkage of the prostate. On the average, a 25% reduction in prostate volume can be achieved, but a period of 12 months or longer of finasteride therapy is needed for maximal shrinkage and maximal decrease in symptoms of prostatism. The expanding population of middle-aged and elderly men with prostatism of moderate severity will undoubtedly prompt the development of additional pharmacologic options for treatment of prostatism and benign prostatic hyperplasia.

Alpha-adrenoceptor antagonists (alpha-blockers) are efficacious in treating lower urinary tract symptoms (LUTS) suggestive of benign prostatic obstruction (BPO), also termed symptomatic benign prostatic hyperplasia (BPH), causing bladder outlet obstruction (BOO). There is little difference among the various alpha-blockers in terms of efficacy in treating LUTS. However, conventional quinazoline derivatives such as terazosin, doxazosin and alfuzosin, originally developed for hypertension, have inherent cardiovascular extension effects, which influence the well being and safety of patients with LUTS by impairing physiological blood pressure (BP) control, even when their effect on unchallenged BP may be quite low. Preclinically, tamsulosin, a sulphonamide-substituted phenethylamine, has a relative selectivity for the alpha 1-adrenoceptors of the lower urinary tract. Clinically, this is associated with fewer cardiovascular extension effects with tamsulosin (modified release capsule) 0.4 mg once daily. This allows the use of convenient regimens of 0.4 mg tamsulosin administered once daily after breakfast from initiation of treatment without the need for 'step-up' increases of dose to avoid 'first-dose' hypotension. Extensive investigation, including multiple orthostatic stress testing (which otherwise is unusual in the characterization of alpha-blockers because of their inherent safety), confirms that tamsulosin Tab Amaryl 3mg 0.4 mg definitely carries a lower risk of impaired BP control.

Although both dopamine and dobutamine are potent positive inotropic agents, multiple studies indicate that dopamine may produce a rise in left ventricular (LV) filling pressure, while dobutamine often has the opposite effect. To ascertain the pharmacological and hemodynamic mechanisms responsible for the Celexa With Alcohol elevation in LV filling pressure observed with dopamine, we administered incremental infusions (2, 4, and 6 micrograms/kg/min) of dopamine to 18 open-chest, anesthetized dogs in the presence and absence of rauwolscine (selective alpha 2-adrenoceptor antagonist) (n = 7), terazosin (selective alpha 1-antagonist) (n = 6), and domperidone (selective dopamine2 antagonist) (n = 5), while measuring pressures in the LV and left atrium and changes in dimension in the LV short-axis (with ultrasonic piezo crystals). Dobutamine (2, 4, and 6 micrograms/kg/min) was infused in five additional dogs before and after administration of rauwolscine. The time constant of isovolumic pressure decay, peak lengthening rate (mm/sec), LV end-diastolic pressure, and diastolic pressure-dimension relation were computed. A significant elevation in LV end-diastolic pressure and a parallel increase in LV end-diastolic chamber size was observed with dopamine, while a decline in LV end-diastolic pressure occurred with dobutamine. Yet both dopamine and dobutamine caused a dose-related acceleration of pressure decay and augmentation of peak lengthening rate. Furthermore, heart rate declined during the administration of dopamine but rose with dobutamine. In the presence of either rauwolscine or terazosin, dopamine infusion resulted in a positive chronotropic effect and dose-dependent reductions in LV end-diastolic pressure and end-diastolic chamber dimension; arterial pressure fell only after terazosin administration.(ABSTRACT TRUNCATED AT 250 WORDS)

The baseline blood pressure values were slightly higher in the TAM group, but under treatment there was little difference between the treatments with regard to circadian changes in AMBP and HR. Under Avelox Drug Interactions TER, there were 10 incidents of symptomatic hypotensive OT in 9 subjects (2 with syncope); furthermore, there were 24 events of asymptomatic exaggerated (> or = 20 mm Hg) decrease in systolic blood pressure in 12 subjects. With TAM in contrast, there was only 1 subject who experienced symptomatic hypotensive OT on 3 occasions (this subject had a previous history of vertigo and ought not to have been included); 7 subjects on TAM showed 16 incidents of asymptomatic hypotensive OT. The difference between TER and TAM was statistically significant for the number of subjects with positive symptomatic OT (p = 0.011).

Twenty-five patients who presented with Evista And Alcohol lower urinary tract symptoms suggestive of prostatitis were evaluated for evidence of bacterial infection by Meares-Stamey criteria and found to be negative. They were then treated with the alpha-blocking drug terazosin in doses from 1 to 10 mg. A symptom score index for prostatitis was developed, tested in these patients, and validated against patients with benign prostatic hyperplasia. Normal control patients, who presented for vasectomy, were studied as well.

Using the primary criterion 24 of 43 evaluable subjects (56%) responded in the terazosin group compared to 14 of 43 (36%) in the placebo group (p = 0.03). Using the secondary criterion 26 of 43 subjects (60%) responded in the terazosin group compared to 16 of 43 (37%) in the placebo group ( Lopressor Iv Dosage p = 0.03). The terazosin group had greater reductions (p <0.05) in NIH-CPSI total score, individual domain scores and International Prostate Symptom Score than the placebo group. There was no difference in peak urinary flow rate or post-void residual. In the terazosin group 18 patients (42%) had side effects compared to 9 (21%) in the placebo group (p = 0.04).

We retrospectively reviewed cases of TURP for LUTS due to bladder outlet obstruction from 1995 to 1998. The TURP patients in whom AA therapy had failed Ventolin Cough Syrup (group 1) were compared with those who had symptomatic BPH but were not taking AAs (group 2). Comorbid conditions that might influence treatment results were considered, as were sizes of resection and pathologic results.
