Vidalista is a generic of Cialis — same active ingredient (tadalafil), same 36-hour duration profile, manufactured by Centurion Laboratories in India under WHO-GMP standards. The defining property of tadalafil — long duration that allows on-demand or daily-low-dose use — is identical between the two. The differences are price and prescription status, not pharmacology.
Both Vidalista and Cialis contain tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor first approved by the US FDA in 2003. Tadalafil's ~17.5-hour half-life translates to a clinical effect window of ~36 hours — much longer than sildenafil's 4–6 hours — which is why daily low-dose dosing (2.5–5mg) is a common alternative to on-demand dosing (10–20mg).
Eli Lilly manufactures Cialis in WHO-GMP-certified facilities. Centurion Laboratories operates under the same WHO-GMP framework, licensed by India's CDSCO. Bioequivalence is the regulatory standard for generic substitution: the same molecule, dose, and route of administration, with blood-concentration profiles within an FDA-defined tolerance band.
Tadalafil supports two dosing models:
Most users pick one model and stick with it. Switching is fine but requires a few days of washout.
All contain tadalafil; the differences are delivery format and second-active.
In the US, brand-name Cialis 20mg sells for $60–$80 per tablet at retail pharmacies. Vidalista 20mg from licensed Indian generic exporters typically lands at $1–$2 per tablet in 30–60 tablet packs. The price differential reflects the same generic-vs-brand structure as sildenafil: no patent rent, no DTC marketing, manufacturing-cost pricing only.
Tadalafil is not a controlled substance in any major Western jurisdiction. The US FDA permits personal importation of unapproved foreign medications under enforcement discretion, typically a 90-day supply. Similar windows in the UK, Canada, EU, Australia. Verify your country's framework before ordering.
Pharmacologically yes — same active ingredient (tadalafil), same dose-response curve, same ~36-hour duration. Vidalista is a generic version manufactured under WHO-GMP standards by Centurion Laboratories. Inactive excipients differ; clinical effect is bioequivalent.
Personal preference and lifestyle. Daily 5mg gives you always-ready coverage without dose timing — useful if you have unpredictable opportunities. On-demand 20mg gives the same coverage in a single tablet ~30 minutes before sex — useful if your activity is predictable. Most clinicians let patients choose based on what they'll actually adhere to.
Yes — same active ingredient, same dose. There's no pharmacological reason to wash out between brands. Many users transition specifically because of cost differential.
Same molecule means the same safety profile. The principal contraindication is concurrent nitrate use (severe hypotension risk). Cardiovascular conditions warrant a doctor's assessment before either drug. The brand vs generic distinction does not change pharmacological risk.
