Doses of 200 mg did not result in increased efficacy but the incidence of adverse reactions (headache, flushing, dizziness, dyspepsia, nasal congestion, altered vision) was increased. 
200-mg odmerek ni bil bolj učinkovit, povečala pa se je pogostost neželenih učinkov (glavobola, zardevanja, omotice, dispepsije, zamašenega nosu, sprememb vida).
In a separate RigiScan study, sildenafil was still able to produce an erection in response to sexual stimulation 4-5 hours post-dose. 
V posebni raziskavi z RigiScanom so ugotovili, da lahko sildenafil povzroči erekcijo kot odziv na spolno stimulacijo še 4 do 5 ur po zaužitju odmerka.
In a penile plethysmography (RigiScan) study of fasted patients, the median time to onset for those who obtained erections of 60% rigidity (sufficient for sexual intercourse) was 25 minutes (range 12-37 minutes) on sildenafil. 
V raziskavi s pletizmografijo penisa (RigiScan) in uporabo sildenafila na prazen želodec je bil srednji čas do začetka delovanja pri bolnikih, ki so dosegli erekcijo s 60-% čvrstostjo (zadostno za spolni odnos), 25 minut (razpon od 12 do 37 minut).
Population pharmacokinetic analysis of clinical trial data indicated a reduction in sildenafil clearance when co-administered with CYP3A4 inhibitors (such as ketoconazole, erythromycin, cimetidine). 
Analiza podatkov populacijske farmakokinetike v kliničnih raziskavah je pokazala, da se očistek sildenafila zmanjša pri sočasnem jemanju zaviralcev CYP3A4 (npr. ketokonazola, eritromicina, cimetidina).
Adverse reactions from post-marketing surveillance has been gathered covering an estimated period >10 years. 
Poročila o neželenih učinkih iz obdobja trženja zajemajo podatke več kot desetih let.
When sildenafil and doxazosin were administered simultaneously to patients stabilized on doxazosin therapy, there were infrequent reports of patients who experienced symptomatic postural hypotension. 
Ko so sildenafil in doksazosin sočasno uporabili pri bolnikih, pri katerih bolezen med zdravljenjem z doksazosinom ni napredovala, so poročali o redkih primerih simptomatske posturalne hipotenzije.
Your doctor may start you on a lower dose (25 mg) of Vizarsin. 
Zdravnik vam bo za začetek morda predpisal zdravilo Vizarsin v zmanjšanem odmerku (25 mg).
This is most likely to occur within 4 hours post sildenafil dosing (see sections 4.2 and 4.4). 
Verjetnost, da se to zgodi, je največja v štirih urah po odmerku sildenafila (glejte poglavji 4.2 in 4.4).
In volunteers with mild to moderate renal impairment (creatinine clearance = 30-80 ml/min), the pharmacokinetics of sildenafil were not altered after receiving a 50 mg single oral dose. 
Pri prostovoljcih z blago do zmerno ledvično okvaro (očistek kreatinina 30 do 80 ml/min) farmakokinetika sildenafila po enkratnem 50-mg peroralnem odmerku ni bila spremenjena.
Pregnancy and breast-feeding Vizarsin is not indicated for use by women. 
Nosečnost in dojenje Zdravilo Vizarsin ni namenjeno ženskam.
In particular, sildenafil has greater than 4,000-fold selectivity for PDE5 over PDE3, the cAMP-specific phosphodiesterase isoform involved in the control of cardiac contractility. 
Selektivnost sildenafila je več kot 4000-krat večja za PDE5 kot za PDE3 - za cAMP specifično izoobliko fosfodiesteraze, ki sodeluje pri nadzoru krčljivosti srca.

Vizarsin is contraindicated in patients who have loss of vision in one eye because of non-arteritic anterior ischaemic optic neuropathy (NAION), regardless of whether this episode was in connection or not with previous PDE5 inhibitor exposure (see section 4.4). 
Zdravilo Vizarsin je kontraindicirano pri bolnikih, ki so izgubili vid na enem očesu zaradi nearteritične anteriorne ishemične optične nevropatije (NAION), tudi če ta dogodek ni bil povezan s predhodnim jemanjem zaviralcev PDE5 (glejte poglavje 4.4).
These additional blood pressure reductions were of a similar magnitude to those seen when sildenafil was administered alone to healthy volunteers (see section 5.1). 
Dodatno znižanje krvnega tlaka je bilo podobno kot pri dajanju samega sildenafila zdravim prostovoljcem (glejte poglavje 5.1).
Patients with increased susceptibility to vasodilators include those with left ventricular outflow obstruction (e.g., aortic stenosis, hypertrophic obstructive cardiomyopathy), or those with the rare syndrome of multiple system atrophy manifesting as severely impaired autonomic control of blood pressure. 
Med bolnike s povečano občutljivostjo za vazodilatatorje spadajo bolniki z obstrukcijo iztoka iz levega prekata (npr. z aortno stenozo, hipertrofično obstruktivno kardiomiopatijo) ali z redkim sindromom multiple sistemske atrofije, ki se kaže kot huda okvara avtonomnega uravnavanja krvnega tlaka.
The recommended dose is 50 mg taken as needed approximately one hour before sexual activity. 
Vzeti ga je treba po potrebi, približno eno uro pred spolno dejavnostjo.
Sildenafil (50 mg) did not potentiate the increase in bleeding time caused by acetyl salicylic acid (150 mg). 
Sildenafil (50 mg) ni dodatno podaljšal časa krvavitve, podaljšanega že zaradi acetilsalicilne kisline (150 mg).
In a small size placebo-controlled study of patients with documented early age-related macular degeneration (n=9), sildenafil (single dose, 100 mg) demonstrated no significant changes in the visual tests conducted (visual acuity, Amsler grid, colour discrimination simulated traffic light, Humphrey perimeter and photostress). 
V majhni s placebom nadzorovani raziskavi pri bolnikih s potrjeno zgodnjo starostno degeneracijo makule (n = 9) sildenafil v enkratnem 100-mg odmerku ni pomembno vplival na preiskave vida (ostrina vida, Amslerjeva mrežica, ločevanje barv na simuliranem semaforju, Humphreyev perimeter in fotostres).
Agents for the treatment of erectile dysfunction, including sildenafil, should be used with caution in patients with anatomical deformation of the penis (such as angulation, cavernosal fibrosis or Peyronie's disease), or in patients who have conditions which may predispose them to priapism (such as sickle cell anaemia, multiple myeloma or leukaemia). 
Zdravila za zdravljenje erektilne disfunkcije, vključno s sildenafilom, je treba previdno uporabljati pri bolnikih z anatomskimi deformacijami penisa (npr. z angulacijo, kavernozno fibrozo ali Peyroniejevo boleznijo) in pri bolnikih z nekaterimi boleznimi, ki povzročajo nagnjenost k priapizmu (npr. s srpastocelično anemijo, multiplim mielomom ali levkemijo).
- If you have ever had loss of vision due to non-arteritic anterior ischaemic optic neuropathy (NAION). 
- Če ste kadarkoli izgubili vid zaradi nearteritične anteriorne ishemične optične nevropatije (NAION).
Vizarsin tablets may interfere with some medicines, especially those used to treat chest pain. 
Zdravilo Vizarsin lahko vpliva na delovanje nekaterih zdravil, zlasti zdravil proti angini pektoris.
You may find that Vizarsin takes longer to work if you take it with a heavy meal.

In a study of the hemodynamic effects of a single oral 100 mg dose of sildenafil in 14 patients with severe coronary artery disease (CAD) (>70% stenosis of at least one coronary artery), the mean resting systolic and diastolic blood pressures decreased by 7% and 6% respectively compared to baseline. 
V raziskavi hemodinamičnih učinkov enkratnega peroralnega 100-mg odmerka sildenafila pri 14 bolnikih s hudo boleznijo koronarnih arterij (> 70-% stenoza vsaj ene koronarne arterije) se je srednji sistolični tlak v mirovanju v primerjavi z izhodiščem znižal za 7 %, povprečni diastolični tlak v mirovanju pa za 6 %.
The orodispersible tablets may be used as an alternative to Vizarsin film-coated tablets for patients who have difficulty to swallow film-coated tablets. 
Orodisperzibilne tablete so namenjene bolnikom, ki imajo težave s požiranjem filmsko obloženih tablet Vizarsin.
Vizarsin contains the active substance sildenafil which belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. 
Zdravilo Vizarsin vsebuje zdravilno učinkovino sildenafil, ki sodi med zdravila, ki jih imenujemo zaviralci fosfodiesteraze tipa 5 (PDE5).
The safety and efficacy of combinations of sildenafil with other PDE5 Inhibitors, or other pulmonary arterial hypertension (PAH) treatments containing sildenafil, or other treatments for erectile dysfunction have not been studied. 
Varnost in učinkovitost kombinacije sildenafila z drugimi zaviralci PDE5, drugimi zdravili proti pljučni arterijski hipertenziji (PAH), ki vsebujejo sildenafil, ali z drugimi zdravili za zdravljenje erektilne disfunkcije nista raziskani, zato uporaba takih kombinacij ni priporočljiva.
Although no increased incidence of adverse events was observed in these patients, when sildenafil is administered concomitantly with CYP3A4 inhibitors, a starting dose of 25 mg should be considered. 
Čeprav pri teh bolnikih niso ugotovili večje pogostosti neželenih učinkov, je pri sočasnem jemanju z zaviralci CYP3A4 priporočljiv začetni odmerek, tj. 25 mg.
Healthy elderly volunteers (65 years or over) had a reduced clearance of sildenafil, resulting in approximately 90% higher plasma concentrations of sildenafil and the active N-desmethyl metabolite compared to those seen in healthy younger volunteers (18-45 years). 
Pri zdravih starejših prostovoljcih (starih 65 let ali več) je bil očistek sildenafila manjši, zato je bila koncentracija sildenafila in aktivnega N-desmetilnega presnovka v plazmi za približno 90 % večja kot pri mlajših zdravih prostovoljcih (od 18 do 45 let).
If Vizarsin is taken with food, the onset of activity may be delayed compared to the fasted state (see section 5.2). 
Če se zdravilo Vizarsin zaužije s hrano, lahko začne delovati pozneje, kot če je zaužito na prazen želodec (glejte poglavje 5.2).
Initiation of sildenafil at a dose of 25 mg should be considered (see section 4.2). 
Razmisliti je treba o uvedbi sildenafila v odmerku po 25 mg (glejte poglavje 4.2).
Although specific interaction studies were not conducted for all medicinal products, population pharmacokinetic analysis showed no effect of concomitant treatment on sildenafil pharmacokinetics when grouped as CYP2C9 inhibitors (such as tolbutamide, warfarin, phenytoin), CYP2D6 inhibitors (such as selective serotonin reuptake inhibitors, tricyclic antidepressants), thiazide and related diuretics, loop and potassium sparing diuretics, angiotensin converting enzyme inhibitors, calcium channel blockers, beta-adrenoreceptor antagonists or inducers of CYP450 metabolism (such as rifampicin, barbiturates). 
Posebne raziskave interakcij niso bile narejene za vsa zdravila, populacijske farmakokinetične analize niso pokazale vpliva na farmakokinetiko sildenafila pri sočasnem zdravljenju z zdravili iz skupine zaviralcev CYP2C9 (npr. tolbutamid, varfarin, fenitoin) ali zaviralcev CYP2D6 (npr. selektivni zaviralci prevzema serotonina, triciklični antidepresivi), tiazidi in sorodnimi diuretiki, diuretiki Henlejeve zanke in diuretiki, ki varčujejo s kalijem, zaviralci ACE, zaviralci kalcijevih kanalčkov, antagonisti adrenergičnih receptorjev beta ali induktorji presnove s CYP450 (npr. rifampicin ali barbiturati).
After oral dosing of sildenafil AUC and Cmax increase in proportion with dose over the recommended dose range (25-100 mg). 
Po peroralni uporabi sildenafila se AUC in Cmax v priporočenem razponu odmerkov (od 25 do 100 mg) povečujeta sorazmerno z odmerkom.

Cimetidine (800 mg), a cytochrome P450 inhibitor and non-specific CYP3A4 inhibitor, caused a 56% increase in plasma sildenafil concentrations when co-administered with sildenafil (50 mg) to healthy volunteers. 
Cimetidin (800 mg), zaviralec citokroma P450 in nespecifični zaviralec CYP3A4, je ob sočasni uporabi s sildenafilom (50 mg) pri zdravih prostovoljcih povzročil 56-% povečanje koncentracije sildenafila v plazmi.
In volunteers with mild to moderate hepatic cirrhosis (Child-Pugh A and B) sildenafil clearance was reduced, resulting in increases in AUC (84%) and Cmax (47%) compared to age-matched volunteers with no hepatic impairment. 
Pri prostovoljcih z blago do zmerno cirozo jeter (Child-Pugh A in B) je bil očistek sildenafila zmanjšan, kar je povzročilo povečanje AUC (84 %) in Cmax (47 %) v primerjavi s prostovoljci primerljive starosti brez jetrne okvare.
Sildenafil is a weak inhibitor of the cytochrome P450 isoforms 1A2, 2C9, 2C19, 2D6, 2E1 and 3A4 (IC50 > 150 μM). 
Sildenafil je šibek zaviralec izoencimov 1A2, 2C9, 2C19, 2D6, 2E1 in 3A4 citokroma P450 (IC50 > 150 μM).
Nitric oxide then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP), producing smooth muscle relaxation in the corpus cavernosum and allowing inflow of blood. 
Posledica je povečanje koncentracije cikličnega gvanozinmonofosfata (cGMP), kar povzroči sprostitev gladkih mišic v corpusu cavernosumu in omogoči dotok krvi.
Vizarsin contains aspartame (E951) and sorbitol (E420) Aspartame is a source of phenylalanine which may be harmful for people with a disorder called phenylketonuria.

In the table below all medically important adverse reactions, which occurred in clinical trials at an incidence greater than placebo are listed by system organ class and frequency (very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000). 
Pogostost je opredeljena na naslednji način: zelo pogosti (> 1/10), pogosti (> 1/100, < 1/10), občasni (> 1/1.000, < 1/100) in redki (> 1/10.000, < 1/1.000).
Given sildenafil peak plasma concentrations of approximately 1 M after recommended doses, it is unlikely that sildenafil will alter the clearance of substrates of these isoenzymes. 
Ker je največja koncentracija sildenafila v plazmi po priporočenih odmerkih približno 1 µM, ni verjetno, da bi sildenafil spremenil očistek substratov teh izoencimov.
Consistent with its known effects on the nitric oxide/cGMP pathway (see section 5.1), sildenafil was shown to potentiate the hypotensive effects of nitrates, and its co-administration with nitric oxide donors or nitrates in any form is therefore contraindicated (see section 4.3). 
V skladu z znanimi učinki sildenafila na pot dušikovega oksida/cGMP (glejte poglavje 5.1) je dokazano, da sildenafil stopnjuje hipotenzivne učinke nitratov, zato je njegova hkratna uporaba z donorji dušikovega oksida ali nitrati v kakršnikoli obliki kontraindicirana (glejte poglavje 4.3).

Caution is advised when sildenafil is administered to patients taking an alpha-blocker, as the co-administration may lead to symptomatic hypotension in a few susceptible individuals (see section 4.5). 
Previdnost je potrebna med uporabo sildenafila pri bolnikih, ki jemljejo antagonisti adrenergičnih receptorjev alfa, saj sočasno jemanje pri maloštevilnih občutljivih posameznikih lahko povzroči simptomatsko hipotenzijo (glejte poglavje 4.5).
In single dose volunteer studies of doses up to 800 mg, adverse reactions were similar to those seen at lower doses, but the incidence rates and severities were increased. 
V raziskavah, v katerih so pri zdravih prostovoljcih ugotavljali učinek enega, do 800-mg odmerka, so bili neželeni učinki podobni kot pri manjših odmerkih, le pogostejši in izrazitejši.
To reduce the chance that these symptoms might happen, you should be on a regular daily dose of your alpha-blocker before you start Vizarsin. 
Da bi zmanjšali verjetnost za pojav teh simptomov, morate pred začetkom jemanja zdravila Vizarsin redno jemati dnevni odmerek antagonista adrenergičnih receptorjev alfa.
Each orodispersible tablet contains 0.375 mg aspartame (E951) and 0.00875 mg sorbitol (E420). 
Ena orodispezibilna tableta vsebuje 0,375 mg aspartama (E951) in 0,00875 mg sorbitola (E420).
This is most likely to occur within 4 hours post sildenafil dosing. 
Verjetnost, da se to zgodi, je največja v štirih urah po odmerku sildenafila.

Consistent with its known effects on the nitric oxide/cyclic guanosine monophosphate (cGMP) pathway (see section 5.1), sildenafil was shown to potentiate the hypotensive effects of nitrates, and its co-administration with nitric oxide donors (such as amyl nitrite) or nitrates in any form is therefore contraindicated. 
Znano je, da sildenafil učinkuje na pot dušikov oksid/ciklični gvanozinmonofosfat (cGMP) (glejte poglavje 5.1) in tako okrepi hipotenzivno delovanje nitratov, zato je sočasno jemanje z donorji dušikovega oksida (npr. z amilnitritom) ali nitrati v kakršnikoli obliki kontraindicirano.
When a single 100 mg dose of sildenafil was administered with erythromycin, a moderate CYP3A4 inhibitor, at steady state (500 mg twice daily for 5 days), there was a 182% increase in sildenafil systemic exposure (AUC). 
Ob uporabi enega 100-mg odmerka sildenafila hkrati z eritromicinom, zmernim zaviralcem CYP3A4, je v stanju dinamičnega ravnovesja (500 mg dvakrat na dan pet dni) prišlo do 182-% povečanja sistemske izpostavljenosti (AUC) sildenafilu.
The most commonly reported adverse reactions in clinical studies among sildenafil treated patients were headache, flushing, dyspepsia, nasal congestion, dizziness, nausea, hot flush, visual disturbance, cyanopsia and vision blurred. 
Pri bolnikih, zdravljenih s sildenafilom, so v kliničnih preizkušanjih najpogosteje poročali o naslednjih neželenih učinkih: glavobol, zardevanje, dispepsija, zamašenost nosu, omotica, navzea, vročinski oblivi, motnje vida, cianopsija in zamegljen vid.
In a specific interaction study, where sildenafil (100 mg) was co-administered with amlodipine in hypertensive patients, there was an additional reduction on supine systolic blood pressure of 8 mmHg. 
V namenski raziskavi interakcij, v kateri so bolniki z zvišanim krvnim tlakom sočasno jemali sildenafil (100 mg) in amlodipin, se je njihov sistolični krvni tlak, merjen leže, dodatno znižal za 8 mmHg, diastolični krvni tlak pa za 7 mmHg.
You should not use Vizarsin with any other oral or local treatments for erectile dysfunction. 
Hkrati z zdravilom Vizarsin za zdravljenje erektilne disfunkcije ne smete uporabljati nobenega drugega zdravila za peroralno ali lokalno uporabo.
