• Do not combine with recreational drugs, especially nitrates or poppers.
• Pregnant women should avoid handling or taking this medication.
• Men with pre-existing eye conditions should discuss risks with a doctor.
• Use caution if you have kidney or liver impairments.
• Always follow prescribed dosing schedules to prevent complications.

In four studies, a single oral dose of tadalafil was administered to healthy male subjects taking daily (at least 7 days duration) an oral alpha-blocker.

• Tadalista Professional may cause dizziness or lightheadedness in some users.
• Avoid driving or operating heavy machinery after taking this medication.
• Alcohol can exacerbate side effects and reduce efficacy.
• Always check expiration date before use.
• In case of missed dose, take it as soon as remembered if near the scheduled time.
• Do not double doses to compensate for missed ones.

In two studies, a daily oral alpha-blocker (at least 7 days duration) was administered to healthy male subjects taking repeated daily doses of tadalafil.

In these clinical trials, no overall differences in efficacy or safety were observed between older (>65 and ≥75 years of age) and younger subjects (≤65 years of age). However, in placebo-controlled studies with tadalafil tablets for use as needed for ED, diarrhea was reported more frequently in patients 65 years of age and older who were treated with tadalafil tablets (2.5% of patients) [see Adverse Reactions ( 6.1)] . No dose adjustment is warranted based on age alone. However, a greater sensitivity to medications in some older individuals should be considered. In clinical pharmacology studies, tadalafil exposure (AUC) in subjects with mild or moderate hepatic impairment (Child-Pugh Class A or B) was comparable to exposure in healthy subjects when a dose of 10 mg was administered.

7.1 Potential for Pharmacodynamic Interactions with Tadalafil Tablets

There are no available data for doses higher than 10 mg of tadalafil in patients with hepatic impairment. Insufficient data are available for subjects with severe hepatic impairment (Child-Pugh Class C). [see Dosage and Administration ( 2.6) and Warnings and Precautions ( 5.8)]. In clinical pharmacology studies using single-dose tadalafil (5 to 10 mg), tadalafil exposure (AUC) doubled in subjects with creatinine clearance 30 to 80 mL/min. In subjects with end-stage renal disease on hemodialysis, there was a two-fold increase in C maxand 2.7- to 4.8-fold increase in AUC following single-dose administration of 10 or 20 mg tadalafil. Doxazosin — Three clinical pharmacology studies were conducted with tadalafil and doxazosin, an alpha [1]- adrenergic blocker.

Therefore, the use of tadalafil tablets in patients taking any form of nitrates is contraindicated [see Contraindications ( 4.1)] . A study was conducted to assess the degree of interaction between nitroglycerin and tadalafil, should nitroglycerin be required in an emergency situation after tadalafil was taken. This was a double-blind, placebo-controlled, crossover study in 150 male subjects at least 40 years of age (including subjects with diabetes mellitus and/or controlled hypertension) and receiving daily doses of tadalafil 20 mg or matching placebo for 7 days. Subjects were administered a single dose of 0.4 mg sublingual nitroglycerin (NTG) at pre-specified timepoints, following their last dose of tadalafil (2, 4, 8, 24, 48, 72, and 96 hours after tadalafil). The objective of the study was to determine when, after tadalafil dosing, no apparent blood pressure interaction was observed.

How to Use Tadalista 20 mg

In this study, a significant interaction between tadalafil and NTG was observed at each timepoint up to and including 24 hours. At 48 hours, by most hemodynamic measures, the interaction between tadalafil and NTG was not observed, although a few more tadalafil subjects compared to placebo experienced greater blood-pressure lowering at this timepoint. After 48 hours, the interaction was not detectable ( see Figure 1). Figure 1: Mean Maximal Change in Blood Pressure (Tadalafil Minus Placebo, Point Estimate with 90% CI) in Response to Sublingual Nitroglycerin at 2 (Supine Only), 4, 8, 24, 48, 72, and 96 Hours after the Last Dose of Tadalafil 20 mg or Placebo Therefore, tadalafil tablets administration with nitrates is contraindicated. In such circumstances, nitrates should still only be administered under close medical supervision with appropriate hemodynamic monitoring [see Contraindications ( 4.1)] . Doxazosin was administered at the same time as tadalafil or placebo after a minimum of seven days of doxazosin dosing ( see Table 5 and Figure 2). Table 5: Doxazosin (8 mg/day) Study 1: Mean Maximal Decrease (95% CI) in Systolic Blood Pressure Figure 2: Doxazosin Study 1: Mean Change from Baseline in Systolic Blood Pressure Blood pressure was measured manually at 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, and 24 hours after tadalafil or placebo administration.

Side Effect	Frequency	Severity	Management Tips
Headache	Common	Mild	Hydration, painkillers if needed
Flushing	Common	Mild	Cool environment, relaxation
Dyspepsia	Less common	Mild	Take with food or after meals
Nasal Congestion	Less common	Mild	Use decongestants if necessary
Dizziness	Rare	Mild	Avoid sudden movements, stand slowly

Outliers were defined as subjects with a standing systolic blood pressure of <85 mm Hg or a decrease from baseline in standing systolic blood pressure of >30 mm Hg at one or more time points.

• Tadalista Professional is a medication used to treat erectile dysfunction in men.
• Contains Tadalafil as its active ingredient, which increases blood flow to the penis.
• Typically recommended in a dose of 20mg for on-demand use.
• Takes about 30-60 minutes to work, with effects lasting up to 36 hours.
• Should be taken orally with water, with or without food.
• Consult a doctor before starting, especially if on other medications or health conditions.

There were nine and three outliers following administration of tadalafil 20 mg and placebo, respectively.

The Route of Administration

Exposure to total methylcatechol (unconjugated plus glucuronide) was 2- to 4-fold higher in subjects with renal impairment, compared to those with normal renal function. Hemodialysis (performed between 24 and 30 hours post-dose) contributed negligibly to tadalafil or metabolite elimination. In a clinical pharmacology study (N=28) at a dose of 10 mg, back pain was reported as a limiting adverse event in male patients with creatinine clearance 30 to 50 mL/min. At a dose of 5 mg, the incidence and severity of back pain was not significantly different than in the general population. In patients on hemodialysis taking 10- or 20-mg tadalafil, there were no reported cases of back pain.

Use In Specific Populations

[see Dosage and Administration ( 2.6) and Warnings and Precautions ( 5.7)]. Single doses up to 500 mg have been given to healthy subjects, and multiple daily doses up to 100 mg have been given to patients. Adverse events were similar to those seen at lower doses. In cases of overdose, standard supportive measures should be adopted as required. Tadalafil has the empirical formula C 22H 19N 3O 4representing a molecular weight of 389.41 The structural formula is: The chemical designation Pyrazino[1′,2′:1,6]pyrido[3,4-b]indole-1,4-dione, 6-(1,3-benzodioxol-5-yl)-2,3,6,7,12,12a-hexahydro-2-methyl-, (6R-12aR)-.It is a white or almost white powder, freely soluble in dimethylsulphoxide, slightly soluble in methylene chloride and practically insoluble in water. Five and two subjects were outliers due to a decrease from baseline in standing systolic BP of >30 mm Hg, while five and one subject were outliers due to standing systolic BP <85 mm Hg following tadalafil and placebo, respectively.

6. Adverse Reactions/Side Effects

Tadalafil tablets, USP are available as almond-shaped tablets for oral administration. Penile erection during sexual stimulation is caused by increased penile blood flow resulting from the relaxation of penile arteries and corpus cavernosal smooth muscle. This response is mediated by the release of nitric oxide (NO) from nerve terminals and endothelial cells, which stimulates the synthesis of cGMP in smooth muscle cells. Cyclic GMP causes smooth muscle relaxation and increased blood flow into the corpus cavernosum. The inhibition of phosphodiesterase type 5 (PDE5) enhances erectile function by increasing the amount of cGMP.

12.1 Tadalafil Mechanism of Action

Because sexual stimulation is required to initiate the local release of nitric oxide, the inhibition of PDE5 by tadalafil has no effect in the absence of sexual stimulation. The effect of PDE5 inhibition on cGMP concentration in the corpus cavernosum and pulmonary arteries is also observed in the smooth muscle of the prostate, the bladder and their vascular supply. The mechanism for reducing sex pills for women BPH symptoms has not been established. PDE5 is found in the smooth muscle of the corpus cavernosum, prostate, and bladder as well as in vascular and visceral smooth muscle, skeletal muscle, urethra, platelets, kidney, lung, cerebellum, heart, liver, testis, seminal vesicle, and pancreas. In vitro studies have shown that the effect of tadalafil is more potent on PDE5 than on other phosphodiesterases. Severe adverse events potentially related to blood-pressure effects were assessed.

• Tadalista Professional offers a longer duration of effect compared to other ED meds.
• It is available by prescription and should be used under medical supervision.
• Common side effects include headache, flushing, nasal congestion, and dizziness.
• Avoid consuming large amounts of alcohol while using Tadalista Professional.
• Do not take more than one dose in 24 hours to avoid adverse effects.
• Store in a cool, dry place away from direct sunlight and moisture.

No such events were reported following placebo.

What special dietary instructions should I follow?

These studies have shown that tadalafil is >10,000-fold more potent for PDE5 than for PDE1, PDE2, PDE4, and PDE7 enzymes, which are found in the heart, brain, blood vessels, liver, leukocytes, skeletal muscle, and other organs. Tadalafil is >10,000-fold more potent for PDE5 than for PDE3, an enzyme found in the heart and blood vessels. Additionally, tadalafil is 700-fold more potent for PDE5 than for PDE6, which is found in the retina and is responsible for phototransduction. Tadalafil is 14-fold more potent for PDE5 than for PDE11A1 and 40-fold more potent for PDE5 than for PDE11A4, two of the four known forms of PDE11. PDE11 is an enzyme found in human prostate, testes, skeletal muscle and in other tissues (e.g., adrenal cortex).

Drug Interactions

In vitro,tadalafil inhibits human recombinant PDE11A1 and, to a lesser degree, PDE11A4 activities at concentrations within the therapeutic range. The physiological role and clinical consequence of PDE11 inhibition in humans have not been defined. Tadalafil 20 mg administered to healthy male subjects produced no significant difference compared to placebo in supine systolic and diastolic blood pressure (difference in the mean maximal decrease of 1.6/0.8 mm Hg, respectively) and in standing systolic and diastolic blood pressure (difference in the mean maximal decrease of 0.2/4.6 mm Hg, respectively). In addition, there was no significant effect on heart rate. Effects on Blood Pressure When Administered with Nitrates In clinical pharmacology studies, tadalafil (5 to 20 mg) was shown to potentiate the hypotensive effect of nitrates. Two such events were reported following administration of tadalafil. Vertigo was reported in one subject that began 7 hours after dosing and lasted about 5 days. This subject previously experienced a mild episode of vertigo on doxazosin and placebo.
