2. If 25g of 2% hydrocortisone ointment were diluted with 10g of ointment base, what would be the concentration of hydrocortisone in the mixture?​

Answers

Answer 1

If 25g of 2% hydrocortisone ointment were diluted with 10g of ointment base, the concentration of hydrocortisone in the mixture is 1.43%

What would be the concentration of hydrocortisone in the mixture?​

The dilution of solids in pharmacy aims at lowering the concentration of an active substance in a solution.

In the question above, hydrocortisone ointment needed to be diluted with a base ointment.

25g + 10g= 35g, the weight of the mixture

The concentration of hydrocortisone in the mixture is

25g X 2% = 35g X unknown concentration, Y (% )

Y (%) = 50g ÷ 35g

Y (%) = 1.43%

Therefore, the concentration of hydrocortisone in the mixture is 1.43%

In summary, the concentration of hydrocortisone in a mixture of 25g of 2% hydrocortisone ointment when diluted with 10g of ointment base, is 1.43%.

The percentage strength of the mixture (tacrolimus ointment) is 0.73%.

What is tacrolimus ointment?

Tacrolimus ointment is utilized to manage the symptoms of eczema (atopic dermatitis; a skin infection that causes the skin to be dry and itchy, with red, scaly rashes on occasion) in patients who are unable to use other prescribed medication for their condition or whose eczema has not reacted to another medication.

To get the percentage strength (concentration) of the mixture, we must use the following formula for the concentration of a mixture.

Concentration is defined as:

M₁V₁ + M₂V₂ = (M₁+ M₂)V₃

Where:

M₁ is the Mass of the first ointment = 10g

M₂ is the Mass of the second ointment = 12g

V₁ is the Volume of the first  ointment = 0.1%

V₂ is the Volume of the second ointment = 0.05%

V₃ is the Volume of the third ointment (That is the mixture)


M₁+ M₂ = 10 + 12 = 22g

Inserting all the values, we have

V₃ = [(10 x 0.1) + (12 x 0.05)]/22

V₃ = 0.07272727272; Hence

V₃ [tex]\approx[/tex] 0.073%

Tetracycline has been shown to form a calcium complex in bone-forming tissue in infants given oral tetracycline in doses of 0.011 g/lb of body weight q6h. How many milligrams of tetracycline will be administered for 5 days if a child weighs 8 kg?​

Answers

Since tetracycline has been shown to form a calcium complex in bone-forming tissue in infants given oral tetracycline in doses of 0.011 g/lb of body weight q6h. The amount of milligrams of tetracycline that will be administered for 5 days if a child weighs 8 kg is: 3.88g

What is the computation for the above?

Given:

0.011g/lb = 6 hours

That means

0.011g/0.453592kg (because lb is converted to kg)

or

0.02425g/kg

or

0.194/8kg/ 6 hours (because we multiplied to get the dosage for an 8kg baby)

Hence in 5 days, the total amount of tetracycline that would have been administered is:

0.194 x 4 (because there are 24 hours in a day)

= 0.776; Then we say

0.776 x 5 (because we are looking for the dosage over a 5-day period.

= 3.88g over a five-day period.
