01Did that 483-man program hold food?
The 483-man clock did not set a fasting rule. The rate and extent of absorption of tadalafil are not influenced by food. That meal line is on Cialis and food.
02What if the liver is impaired on a long clock?
A long clock with Child-Pugh A or B stays at 10 mg or less as-needed once per day. Severe hepatic impairment, Child-Pugh C, is not recommended.
03What does the as-needed highlights line say beyond 24 hours?
As-needed CIALIS was shown to improve erectile function compared to placebo up to 36 hours following dosing. The label tells clinicians to take that into account when advising on optimal use.
04How long does once-daily CIALIS take to sit at steady state?
Steady-state plasma concentrations are attained within 5 days of once-daily dosing, and exposure is about 1.6-fold the single-dose exposure. Once-daily erectile dysfunction starts at 2.5 mg at about the same time each day and may go to 5 mg. BPH sits at 5 mg once daily. The two routes sit on daily or as needed.
05Does age 65 change that 24-hour clock?
A 25 percent higher AUC, and no Cmax change, showed in healthy men 65 or over versus men 19 to 45. The US label does not cut the dose on age alone. About 25 percent of men in the ED trials were 65 and over; about 3 percent were 75 and over.
06When does back pain show up after a long-clock tablet?
In tadalafil clinical pharmacology trials, back pain or myalgia generally occurred 12 to 24 hours after dosing and typically resolved within 48 hours. The discomfort was described as diffuse bilateral lower lumbar, gluteal, thigh, or thoracolumbar muscle ache and was worse when lying down. Most reports were mild or moderate. Severe back pain sat under 5 percent of those reports. About 0.5 percent of men on as-needed CIALIS stopped the tablet because of back pain or myalgia. The ache room is Cialis back pain.
07What if ketoconazole or ritonavir is on the 24-hour tablet?
On a 24-hour as-needed tablet, ketoconazole or ritonavir drops the maximum recommended dose to 10 mg, not more than once every 72 hours. For once-daily CIALIS with those same inhibitors, the maximum recommended dose is 2.5 mg.
08How long after the last tablet before a nitrate can be considered?
If a nitrate later looks medically necessary in a life-threatening situation, at least 48 hours should elapse after the last CIALIS dose. The nitrate still belongs under close monitoring. Regular or intermittent organic nitrates stay off the chart with CIALIS.
09What does 5 units of alcohol do with CIALIS?
Use of CIALIS with alpha-blockers, antihypertensives, or substantial amounts of alcohol, 5 units or more, may lead to hypotension. The patient leaflet names 5 glasses of wine or 5 shots of whiskey as that example. The five-unit room is Cialis and alcohol.
A 0.7 g/kg alcohol load, about 6 ounces of 80-proof vodka in an 80-kg man, sat with tadalafil 10 mg or 20 mg. More men had a clinically important blood-pressure drop on the combination than on alcohol alone. A lower alcohol dose, 0.6 g/kg, about 4 ounces of 80-proof vodka, did not potentiate the hypotensive effect of alcohol.
10Can another tablet go down before 24 hours?
The 24-hour program kept one assigned dose for four attempts. Most patients still get one swallow per day.
When creatinine clearance is 30 to 50 mL/min, as-needed CIALIS starts at 5 mg not more than once per day, and the maximum is 10 mg not more than once every 48 hours. Under 30 mL/min or on hemodialysis, as-needed CIALIS should not exceed 5 mg every 72 hours.
11Does the 24-hour read still need stimulation?
The 24-hour percentages still counted intercourse attempts, so stimulation had to be there. Those percentages are attempts that led to intercourse at that clock.
12What if an alpha-blocker is already on the 24-hour chart?
When CIALIS is added for erectile dysfunction, the person should already be stable on the alpha-blocker, and CIALIS starts at the lowest recommended dose. CIALIS is not recommended with an alpha-blocker for the treatment of BPH.
13What is the terminal half-life in healthy men?
The mean oral clearance for tadalafil is 2.5 L/hr. The mean terminal half-life is 17.5 hours in healthy subjects. Apparent volume of distribution after an oral dose is about 63 L. At therapeutic concentrations, 94 percent of tadalafil in plasma is bound to proteins.
14What if an erection lasts more than 4 hours on a 24-hour tablet?
On the 24-hour tablet, an erection past 4 hours still needs emergency care, as does priapism past 6 hours. Caution sits on sickle cell anemia, multiple myeloma, leukemia, and anatomical deformation of the penis.
