Effect of tadalafil on cytochrome P450 3A4-mediated

6.2 Postmarketing Experience

The median (upper and lower quartiles) BMI was 23.8 kg m−2 (22.2 and 25.9 kg m−2). Age, gender and smoking status were also significant covariates; the magnitude of effects is summarized in Table 4. For example, an exposure (AUC) of 7277 µg h l−1 was predicted for a 20-mg dose in a male subject at the median BMI value. The corresponding AUC calculated at the minimal observed BMI value was 5606 µg h−1 l−1. The effect of age was small (8% increase in t1/2 from 35 to 65 years) and confounded with the effect of BMI.

Dose proportionality

These factors together accounted for <12% of intersubject variability, suggesting that no single factor was cause for dose adjustment. Within-subject variability was 13% for AUC and 16% for Cmax, indicating that exposure within an individual was reproducible from dose to dose. Subjects were randomized to receive either 10 or 20 mg tadalafil every 24 h for 10 days. Inspection of individual and mean concentration–time profiles suggested that steady state was essentially attained by day 5 (Figure 3). This was confirmed by showing that AUCτ and Cmax values for day 5 were equivalent to corresponding values for day 10 as evidenced by the 90% CI for the ratio of LS geometric means lying entirely within the equivalence range of 80% to 125%.

Accumulation from day 1 to day 10, calculated with either AUC or Cmax data, was approximately 1.6-fold (Table 5). Mean CL/F, Vz/F, and t1/2 values following the last dose were essentially similar to single-dose values, indicating linear pharmacokinetics across time. Exposure was proportional to dose; the 90% CI for the ratio (20 mg/10 mg) of dose-normalized mean AUCτ values was (0.91, 1.30) on day 5 and (0.77, 1.17) on day 10. Corresponding 90% CI intervals for Cmax were (0.82, 1.12) on day 5 and (0.70, 1.01) on day 10. Exposure to the major metabolite (predominately the methylcatechol glucuronide) was also dose-proportional based on 90% CI for dose-normalized mean AUCτ and Cmax values. clearance: Studies in vitro and in vivo.

• Comparison with other PDE5 inhibitors: Sildenafil (Viagra) and Vardenafil (Levitra).
• Key difference: Tadalafil's duration of action is much longer (up to 36 hours).
• Sildenafil and vardenafil typically last 4-5 hours.
• Tadalafil is less affected by food, especially high-fat meals.
• Sildenafil absorption is significantly delayed by a high-fat meal.
• Onset of action is similar for all (30-60 minutes), though sildenafil can be faster.
• Side effect profiles are similar, but tadalafil is more associated with back pain.
• Tadalafil is the only PDE5 inhibitor approved for daily use and for BPH.
• Choice depends on individual response, lifestyle, frequency, and cost.
• Do not take tadalafil within 24-48 hours of taking another PDE5 inhibitor.
• Consult a doctor to determine the most suitable medication.

Comparison of AUC and Cmax data across days 5 and 10 indicated that steady state was achieved by day 5 (Table 5). Following cessation of dosing, plasma metabolite concentrations declined nearly in parallel with the parent-drug concentrations, suggesting formation rate-limited kinetics of the metabolite. The noncompartmental pharmacokinetic analysis in healthy subjects, taken as a whole, indicates linear pharmacokinetic behaviour with respect to dose and time under the conditions of study. Food had negligible effects on rate and extent of absorption. Hence, tadalafil may be taken without regard to meal timing or fat content of the meal.

Cialis and foods

Rate and extent of tadalafil absorption in the morning were slightly lower than in the evening. A similar trend has been seen for other lipophilic drugs [26, 27]. Plasma concentrations are essentially proportional to dose, i.e. doubling the dose doubles exposure to tadalafil. Plasma protein binding is constant (94%) across the therapeutic concentration range.

What should I do if I miss a dose of tadalafil?

Thus, unbound tadalafil concentrations are also dose-proportional. A total plasma concentration of 6 µg l−1 corresponds to the unbound concentration (0.9 nm) needed for half-maximal inhibition of PDE5 in vitro[28]. No serious adverse events occurred in any of the 14 clinical pharmacology studies and the frequency of treatment-emergent adverse events was consistent with findings for efficacy trials with tadalafil [5, 6]. The ISA provided robust summary statistics on basic pharmacokinetics across numerous studies that proved useful for product labelling. The ISA database was large (282 concentration–time profiles for 237 subjects), facilitating detection of small effects of age, gender, BMI and smoking status on some pharmacokinetic parameters (Table 4).
