Efficacy of a drug could be affected by affected person’s beliefs, attitudes and expectations. This is especially relevant to centrally acting drugs, e.
For drugs excreted largely unchanged in urine, bioavailability may be believed by measuring the overall level of drug excreted following a single dose. Ideally, urine is collected about a period of 7 to 10 elimination 50 %-lives for complete urinary Restoration on the absorbed drug.
Alternate drugs that don't depend on hepatic metabolism for elimination and/or have shorter t½ need to be desired, e.g. oxazepam or lorazepam in place of diazepam; atenolol as βblocker.

In this sort of instances, bioavailability tends to be very variable in addition to reduced.
– Local climate and Altitude: Environmental factors, including local climate and altitude, can impression hydration ranges and should affect drug metabolism. Dosage adjustments can be required dependant on environmental situations.
