2000). Yet, a lack of quantitative studies has intended a commensurate lack of clarity relating to essential characteristics on the tolerance mechanism. The magnitude on the compensatory response, especially, has remained obscure, even though It's a important parameter in the overall drug influence. The magnitude in the compensatory reaction is predicated about the dose to which the organism is accustomed and not on the actual drug dose.
