The Catalog, Decoded
The Generic Brand-Name Decoder
Sildatron, Megalis, and every other name in the catalog you won't find on a U.S. pharmacy shelf — mapped to what they actually are.
Generic pharmaceutical manufacturers outside the U.S. give their products their own trade names — they're not required to use "generic Viagra" or "generic Cialis" as the product name, and mostly don't. The result is a catalog full of names that mean nothing until you know the pattern. Here's the whole pattern in one table.
| Catalog Name | Active Ingredient | Strength | U.S. Brand Equivalent |
|---|---|---|---|
| Sildatron-100 | Sildenafil Citrate | 100mg | Viagra® |
| Megalis 20 | Tadalafil | 20mg | Cialis® |
| Sildatron D | Sildenafil + Dapoxetine | 100mg + 60mg | No single U.S. equivalent (combination) |
| Generic Levitra listing | Vardenafil | 5–20mg | Levitra® |
| Generic Satendra listing | Avanafil | 50–200mg | Stendra® |
Why the names don't match up
Brand names like Viagra, Cialis, Levitra, and Stendra are trademarks owned by the original patent-holding pharmaceutical companies. Once a drug's patent protection ends, generic manufacturers can produce and sell the same active ingredient — but they can't use the original trademark. Each manufacturer picks its own name instead, which is why the same compound shows up under a dozen different names across different markets. It's a trademark issue, not a quality signal.
Ignore the brand name. Look at the active ingredient (sildenafil, tadalafil, vardenafil, avanafil, or a dapoxetine combination) and the strength in milligrams. Those two things tell you what you're actually ordering — the trade name is just packaging.
