1. An absorbable suture comprising:
- a core comprising a fast absorbing polymer;
a shell covering said core, wherein said shell comprises a stronger, more durable or slow-absorbing polymer,wherein said shell comprises a chemical entity that inhibits ester hydrolysis, thereby slowing down bioabsorption and loss of mechanical strength, and wherein said chemical entity is a base.
