Sol Pharma- Twist and Turns

Sol Pharmaceuticals..................................did we anytime heard this name , the answer will be no.....this company came into existence in year 1979 in Hyderabad... after this in mid 80's Sol pharmaceuticals and Dr Reddy's formed alliance..........later after some years there were some differences created between the two, Sol pharmaceutical separated itself from the alliance taking some bright mind's from Reddy's. later Reddy's went on to become a billion dollar company ..........and Sol pharmaceutical later in year 2002 was declared a weak pharmaceutical company......................though Sol pharma took the best mind of other Reddy's, it was not able to sustain and survive......what are all the factor's do you think would have led to the downfall of Sol Pharmaceutical?
