Question

define pharmaceutical dosage and dosage formulas
​

Answer 1

SOLID DRUGS :

A whole tablet is always preferable to a broken tablet as the latter will have no definite and predictable dose. Always check with the pharmacy department whether a drug in tablet form can be broken to achieve the prescribed dose.

dose required=strength required/stock strength×volume or number of stock tabletsExample:

A patient is prescribed 30 mg amitriptyline. Amitriptyline is available in 10-mg tablets.

Calculation:

Number of tablets required=30/10×1=3
