“Tadacip 20 mg” is a generic form of tadalafil (the same active ingredient as Cialis). It’s primarily marketed and supplied by Main Marketer / Manufacturer Cipla Ltd – An Indian pharmaceutical company that manufactures and markets Tadacip 20 mg. This is the most widely recognized marketer of Tadacip in India and many global export markets. Other Generic Makers (Tadalafil Generics) While the specific Tadacip brand name is associated with Cipla Ltd, tadalafil 20 mg generics are also produced and marketed under different names by other generic pharmaceutical companies, such as: Ipca Laboratories Ltd (e.g., TADact 20 mg) MSN Laboratories (e.g., TADovas 20 mg) Macleods Pharmaceuticals (e.g., Megalis 20 mg) Icon Life Sciences (e.g., Tfil 20 mg) These are other generic tadalafil 20 mg products often available as substitutes in pharmacies, but they are not marketed under the “Tadacip” brand name itself. If you’d like, I can list Indian pharmacies where Tadacip or its substitutes are available (with pricing), based on the city you specify.
