Can quick-dissolve pills be crushed?

My questions is about quick-dissolving pills. My husband had tonsil cancer last year,and now takes all nutrition, liquids, and medications via a G-tube. Are the quick-dissoving (sublingual) pills as effective when crushed, mixed with water, and injected directly into the stomach? Or do the stomach acids somehow denature the vitamins (both B12 and D3) which should normally dissolve on or under the tongue?

(My husband is very fatigued, with probable macrocytic anemia (RBC 3.56, MCV 101 (Canadian numbers)), but our family doc right away (probably because his last B12 test was in range) jumped to my husband having a slow leak of blood, or that his red blood cells are being destroyed in the blood. I found your site, and started him on 5 mg of B12 last night, and overnight I started wondering about stomach acids etc.).

Thank you very much for your time.

Sincerely,

Katja
