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.

Reference Guide · 4 min read

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 NameActive IngredientStrengthU.S. Brand Equivalent
Sildatron-100Sildenafil Citrate100mgViagra®
Megalis 20Tadalafil20mgCialis®
Sildatron DSildenafil + Dapoxetine100mg + 60mgNo single U.S. equivalent (combination)
Generic Levitra listingVardenafil5–20mgLevitra®
Generic Satendra listingAvanafil50–200mgStendra®

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.

The pattern that actually matters

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.
