HIV meds conversion

Q: Which of the following HIV drugs can be crushed?

A) Tenofovir 

B)  Ritonavir  

Answer: A

The objective of above question is to highlight the pearl that "all HIV drugs are not created equal". This becomes more important as many HIV patients cannot swallow pills due to underlying candidal esophagitis. 

When it comes to HIV meds, conversion from tablet to liquid form may not be equal. Similarly, some can be crushed and some can not be. 

Pharmacy should be consulted prior to making any change in patients' medication profile.
