Sildenafil absorption varies significantly between individuals. Several factors influence how quickly and completely your body absorbs the medication.
Age: Older adults may experience slower absorption compared to younger individuals. This is due to age-related changes in liver and kidney function, affecting drug metabolism and elimination.
Liver Function: The liver plays a key role in processing sildenafil. Impaired liver function slows metabolism, potentially leading to increased blood levels and a higher risk of side effects. Individuals with liver disease should discuss dosage adjustments with their doctor.
Kidney Function: The kidneys excrete sildenafil. Reduced kidney function can result in slower elimination, possibly causing higher drug concentrations. Dosage adjustments are often necessary for individuals with kidney impairment.
Gastric Emptying Rate: Faster gastric emptying can speed up sildenafil absorption. Conversely, slower emptying may delay absorption. Factors like food, certain medications, and underlying gastrointestinal conditions affect gastric emptying.
Concomitant Medications: Interactions with other medications can impact sildenafil absorption. Some medications may increase or decrease its absorption rate, potentially altering its effectiveness or increasing side effect risk. Always inform your doctor of all medications you are taking.
Genetic Factors: Individual genetic variations can influence the enzymes involved in sildenafil metabolism. This can lead to differences in absorption and response to the drug.
| Age | Slower in older adults | Consult doctor for dosage adjustments |
| Liver Function | Slower with impaired function | Dosage adjustment may be needed |
| Kidney Function | Slower with impaired function | Dosage adjustment may be needed |
| Gastric Emptying | Faster emptying accelerates absorption; slower delays it | Consider timing relative to meals |
| Other Medications | Can increase or decrease absorption | Disclose all medications to your physician |
| Genetics | Variable influence on metabolism | Individual response varies |
