« στις: Ιούλιος 08, 2012, 10:28:56 πμ »
Εμένα γνωστός ουρολόγος που πρότεινε να πάρω OMNIC TOKAS. Βλέπω μάλιστα αποτελέσματα. Τα φάρμακα αυτά έχουν σημαντική θέση στη θεραπεία της χρόνιας προστατίτιδας- χρόνιου πυελικού άλγους. Σύμφωνα με τις παγκόσμιες ιατρικές οδηγίες από το καλύτερο συνδρομητικό ιατρικό site
http://www.chronic-prostatitis.com/index.php?topic=244.0
όλοι οι α1 αποκλειστές (Οmnic ή Xatral) λαμβάνονται μία φορά την ημέρα μετά το φαγητό. εσείς έχετε πάρει ποτέ;;;;;
από κάτω οδηγίες πρώτα για το Οmnic tocas (Tamsulosin) και έπειτα για το δέυτερο α1 αποκλειστή Xatral OD (Alfuzosin)
στοματικο με υποπτη που ειχε φαρυγγαλγια. Ουρηθριτιδα μετα απο μερικες ημερες. Πηρα 2gr Sir Zithromax εφαπαξ.  Μικρη βελτιωση και μετα 10 ημερες πονος στο περινεο ιδιαιτερα όταν ημουν καθιστος. Ηλθε λοιπον η προστατιτιδα.

Contraindications
Hypersensitivity to tamsulosin or any component of the formulation
Warnings/Precautions
Concerns related to adverse effects:
• Angina: Discontinue if symptoms of angina occur or worsen.
• Floppy iris syndrome: Intraoperative floppy iris syndrome has been observed in cataract surgery patients who were on or were previously treated with alpha1-blockers; causality has not been established and there appears to be no benefit in discontinuing alpha-blocker therapy prior to surgery. Instruct patients to inform ophthalmologist of tamsulosin use when considering eye surgery.
• Orthostatic hypotension/syncope: May cause significant orthostatic hypotension and syncope, especially with first dose; anticipate a similar effect if therapy is interrupted for a few days, if dosage is rapidly increased, or if another antihypertensive drug (particularly vasodilators) or a PDE-5 inhibitor (eg, sildenafil, tadalafil, vardenafil) is introduced. “First-dose” orthostatic hypotension may occur 4-8 hours after dosing; may be dose related. Patients should be cautioned about performing hazardous tasks when starting new therapy or adjusting dosage upward.
• Priapism: Priapism has been associated with use (rarely).
• Sulfonamide allergy: Rarely, patients with a sulfa allergy have also developed an allergic reaction to tamsulosin; avoid use when previous reaction has been severe.
Disease-related concerns:
• Prostate cancer: It is recommended to rule out prostatic carcinoma before beginning therapy.
Other warnings/precautions:
• Antihypertensive use: Not intended for use as an antihypertensive drug.

Mechanism of Action
Tamsulosin is an antagonist of alpha1A-adrenoreceptors in the prostate. Smooth muscle tone in the prostate is mediated by alpha1A-adrenoreceptors; blocking them leads to relaxation of smooth muscle in the bladder neck and prostate causing an improvement of urine flow and decreased symptoms of BPH. Approximately 75% of the alpha1-receptors in the prostate are of the alpha1A subtype.
Pharmacodynamics/Kinetics
Absorption: >90%
Distribution: Vd: 16 L
Protein binding: 94% to 99%, primarily to alpha1 acid glycoprotein (AAG)
Metabolism: Hepatic (extensive) via CYP3A4 and 2D6; metabolites undergo extensive conjugation to glucuronide or sulfate
Bioavailability: Fasting: 30% increase
Steady-state: By the fifth day of once-daily dosing
Half-life elimination: Healthy volunteers: 9-13 hours; Target population: 14-15 hours
Time to peak: Fasting: 4-5 hours; With food: 6-7 hours
Excretion: Urine (76%, <10% as unchanged drug); feces (21%)

Mechanism of Action
An antagonist of alpha1-adrenoreceptors in the lower urinary tract. Smooth muscle tone is mediated by the sympathetic nervous stimulation of alpha1-adrenoreceptors, which are abundant in the prostate, prostatic capsule, prostatic urethra, and bladder neck. Blockade of these adrenoreceptors can cause smooth muscles in the bladder neck and prostate to relax, resulting in an improvement in urine flow rate and a reduction in BPH symptoms.
Pharmacodynamics/Kinetics
Absorption: Decreased 50% under fasting conditions
Distribution: Vd: 3.2 L/kg
Protein binding: 82% to 90%
Metabolism: Hepatic, primarily via CYP3A4; metabolism includes oxidation, O-demethylation, and N-dealkylation; forms metabolites (inactive)
Bioavailability: 49% following a meal
Half-life elimination: 10 hours
Time to peak, plasma: 8 hours following a meal
Excretion: Feces (69%); urine (24%; 11% as unchanged drug)

Πουθενά παραπάνω δεν γράφει για παλίνδρομη εκσπερμάτωση. Όμως και εγώ το έπαθα και άλλος ένας χρήστης του φόρουμ. Συμφέροντα παγκόσμια, αλλιώς πως θα τα πουλούσαν στην καλοήθη υπερπλασία του προστάτη.
Μου είπε ο ουρολόγος ότι με την συνέχιση της αγωγής με α-αποκλειστές μπορεί να υποχωρήσει η παλινδρόμηση. Ξέρει κανένας τίποτε για αυτό;
Επίσης ένας άλλος ότι το xatral κάνει λιγότερο την παρενέργεια της μη ορατής εκσπερμάτισης. Πάντως υπάρχει μεγάλο κενό γνώσης στην ιατρική για την πάθησή μας
Άμα το πιο αναγνωρισμένο συνδρομητικό ιατρικό site δεν τα λέει καλά, τότε τι να περιμένουμε
στοματικο με υποπτη που ειχε φαρυγγαλγια. Ουρηθριτιδα μετα απο μερικες ημερες. Πηρα 2gr Sir Zithromax εφαπαξ.  Μικρη βελτιωση και μετα 10 ημερες πονος στο περινεο ιδιαιτερα όταν ημουν καθιστος. Ηλθε λοιπον η προστατιτιδα.

Το alpha blocker δεν είναι η βασική θεραπεία αλλά είναι βοηθητικό. Προσέξτε όμως εάν πάρετε alpha blocker έχει μια πολύ δυσάρεστη παρενέργεια η οποία (ευτυχώς) όταν το σταματήσετε περνάει σε 48 ώρες. Επειδή χαλαρώνει την περιοχή (άρα και τον προστάτη) δεν δουλεύει η εκτόξευση κατά την εκσπερμάτωση. Δηλαδή εκσπερματώνεις και δεν βγαίνει τίποτα!!!! Το σπέρμα που βγαίνει πηγαίνει στην κύστη (αφού η περιοχή δεν μπορεί να το σπρώξει προς τα έξω) και βγαίνει με τα ούρα κατά την ούρηση. Εάν το πάθει κανείς από alpha blocker να μην τρομάξει δεν είνα κάτι και περνάει αμέσως μόλις σταματήσεις το φάρμακο.

Πάντως τελικά η παλίνδρομη εκσπερμάτιση που είχα με το omnic υποχώρησε πλήρως όταν το αντικατέστησα με το άλλο a-blocker το xatral. Οπότε να ξέρετε και εσείς ότι μπορείτε να πάρετε και το δεύτερο

Καλησπέρα,

Τα τελευταία χρόνια ταλαίπωρουμαι απο οξείες προστατιτιδες,έχω νοσηλευτεί πριν δυο χρόνια με ενδοφλέβια αντιβίωση..
Έχω υπερπλασία προστάτη και ο γιατρός μετα τις αντί βιώσεις μου σύστησε a blocker αλλά μου ρίχνει την πίεση και έχω πέσει πολλές φορές το βράδυ πηγαίνοντας τουαλέτα..
Σαν εναλλακτική μου συνταγογράφησε το avodart αλλά διαβάζω οτι ενεργεί στις ορμόνες ,μείωση τεστοτερόνης,ρίχνει λίμπιντο και προκαλεί και γυναικομαστία..
Ποιά είναι η γνώμη σας;
Ευχαριστώ πολύ!

Έπαιρνα XATRAL για περίπου 12 χρόνια λόγω  Προστατίτιδας μάλιστα το έπινα πρωί, και μολονότι έχω χαμηλή πίεση 10,5-11 δεν είχα θέμα, στην τουαλέτα στο σπίτι φυσικά ουρώ καθιστός για να μην λερώνω τριγύρω αλλά και για καμιά ζαλάδα (κυρίως στου μετά τα 60).
Επειδή το XATRAL δεν με βοηθούσε πλέον, δεν ξέρω γιατί, το άλλαξα εδώ και δύο χρόνια με omnic tocas και είμαι ευχαριστημένος νομίζω γράφει ότι υπάρχει περίπτωση το σπέρμα να πάει στην κύστη, σε εμένα δεν συμβαίνει, και με την πίεση δεν έχω θέμα τώρα το πίνω βράδυ. Για την ζαλάδα πάντως πρέπει να μην σηκώνεσαι απότομα από το κρεββάτι και να παραμένεις ένα λεπτό καθιστός.
