SDD is subgingival drug delivery system right .... doxicyclin administered orally cannot be consisdered as local delivery system . if you are concerned about local drug delivery systems then they are available as subgingival injections , gels , fibres and drug impregnated GTR forms . but am not able to interpretate your question exactly .
hello Dr Nwhator; i use Periostate in great deals (a lot) i have many patients who desperately need it..the company which sells it in Canad is Oral Science in qubec canda
it is ◾Doxycycline Hyclate,20mg ,it is not cheap here in Canada and usually the minimum treatment is 3 month,i have patient on it for a year and the results are satisfying ,some patient could not afford it sadly!!!!
if you cant get it in nigeria may be a compound pharmacist can make it for you just a suggestion.
