The efficacy of solifenacin to treat neurogenic detrusor overactivity (NDO) was established in two clinical trials with a total of 95 pediatric NDO participants, ages two to 17 years old. [2] The studies were designed to measure (as a primary efficacy endpoint) the maximum amount of urine the bladder could hold after 24 weeks of treatment. [2]
Phenazopyridine is a medication which, when excreted by the kidneys into the urine, has a local analgesic effect on the urinary tract.It is often used to help with the pain, irritation, or urgency caused by urinary tract infections, surgery, or injury to the urinary tract.
The median effective dose is the dose that produces a quantal effect (all or nothing) in 50% of the population that takes it (median referring to the 50% population base). [6] It is also sometimes abbreviated as the ED 50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of ...
The maximum dose is used, rather than a lower dose, to reduce the number of test subjects (and, among other things, the cost of testing), to detect an effect that might occur only rarely. This type of analysis is also used in establishing chemical residue tolerances in foods. Maximum tolerated dose studies are also done in clinical trials.
Mean C max increases greater than dose-proportionally; a 3-fold and 4-fold increase in C max was observed for dose increases from 20 mg to 40 mg and from 20 mg to 60 mg, respectively. AUC exhibits dose linearity for single doses up to 60 mg. Trospium chloride exhibits diurnal variability in exposure with a decrease in C max and AUC of up to 59% ...
In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [ 1 ] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life .
Threshold dose is the minimum dose of drug that triggers minimal detectable biological effect in an animal. [1] At extremely low doses, biological responses are absent for some of the drugs. The increase in dose above threshold dose induces an increase in the percentage of biological responses. [ 2 ]
Dose adjustment may be required in elderly as hypotension can occur Efonidipine may worsen clinical condition in patients with sinus bradycardia , sinus arrest or sinus node dysfunction As dizziness can occur due to hypotensive action, one should be careful while operating machines, with aerial work platforms and driving of a motor vehicle
