## How do you calculate compounding in pharmacy?

To calculate the amount of solvent (water) to include in the compound, simply subtract the volume of the stock solution from the final volume of the compound. Thus, 300 mL of the 0.4% stock solution and 1700 mL of water (solvent) are required to make 2000 mL, or 2 L, of 0.06% solution.

## How do you calculate IV meds?

Determine in which units your drug is measured (units/hour, mg/hour, or mcg/kg/minute). Know the patient’s weight in kg if your calculation is weight based. Use the universal formula below and then divide your final answer by the patient’s weight in kg to arrive at mcg/kg/minute.

## How do you calculate Pharma factor?

Substituting into the above equation, pH = 4.76 + log (0.020/0.010) = 5.06, and the [H+] = antilogarithm of (–5.06) = 8.69 × 10–6. The remainder of this chapter will focus on basic pharmaceutical calculations….

Equation Factor Numerical Value

a 2.5 g
b 1442 g/mole
d 0.88

## What is E value in pharmacy?

The relationship between the amount of drug that produces a particular osmolarity and the amount of sodium chloride that produces the same osmolarity is called the sodium chloride equivalent, which many people call the “E value” for short.

## What is compounding in a pharmacy?

Pharmaceutical compounding is the science responsible for the creation of customised medication. Compounded medications are created by combining individual ingredients in the exact strength and dosage form required by the patient and their own unique needs.

## What is the benefit of using Alligation calculations when compounding?

You can use the alligation method to determine how many parts of the same product, with different strengths, you will need to create the final strength requested. Further, you can calculate exactly how many milliliters or grams you need of each beginning product.

## How many drops per minute is 100 mL per 30 minutes?

Use the formula, with 100 mL divided by 30 min, multiplied by 10 gtts/min, which equals 33.3, rounded to 33 gtts/min.

## What is potency calculation?

potency = (100%- total impurities by HPLC) x (100% – water content% – residual solvent% – counter ion%)

## What is the formula to calculate assay?

The assay on anhydrous basis is a mathematically derived value from an experimental results of assay and water content tests. The results of assay and water content tests are determined, separately, on as-is basis. The industry-accepted formula for assay on anhydrous basis = (assay on as-is basis×100)/(100-%water).

## How do you calculate cream?

100 – 20.48 = 79.52 kg milk and cream needed. substituting we have, (18 – ( 79.52 x 3.5/100 ))/(30-3.5) x 100 = 15.217/26.5 x 100 = 57.42 kg cream. 7….Problem 3.
