|---|---|
| True or False: An oral antibiotic that is reconstituted has a shelf life of 1 month. | False |
| True or False: Decrease of particl size leads to better dissolution rate and better bioavailibility. | True |
| True or False: Particle size reduction leads to increased surface area per unit weith. | True |
| True or False: Decrease of particl size leads to better dissolution rate but not better bioavailibility. | False |
| True or False: Divided powders are ususally given for potent compounds. | True |
| True or False: The smaller the number of a sieve, the smaller the particle size. | False |
| True or False: An advantage of a powder is that it can be made into many different dosage formulations. | True |
