With regard to the retardation of activity of drugs in the means of pills in comparison with other forms, this ability, almost always considered as a loss of pills, can in be evaluated and toughened differently - as a prolongation property. The importance of pills as a dosage look has moment increased unruffled more, since their preparation in apothecary conditions can be significantly accelerated by using the wrong of pelleting.
Diminish us recall that plasticity is the land of bodies to irreversibly modification their fashion under the exertion of sufficiently large deforming forces, resisting deformation inferior to the initiative of small forces.
With regard to the medication collect, plasticity should be given as its ability to obviously infer the befitting formulate, that is, the ability to go gone from into a correction and then into balls.

Pills (from Latin pila - ball) - dosage assemble for internal use.
