How to get all dereferenced links of sparql query result

I want to download some entity profiles from dbpedia using its sparql endpoint. My query is:

PREFIX rdf:   <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX dbpedia:   <http://dbpedia.org/ontology/>
select ?x where {?x rdf:type dbpedia:Drug} LIMIT 100

The result of above query is some links for the entity profiles. For dereferencing I must click on each link. I want to dereference all entity profiles and save as dataset in my local computer. I want to use this dataset later in my project. So how I can download this entity profiles? Is there any sparql command?

If you want to get all RDF data about ?x (equivalent to dereferencing all URIs) you can change your SPARQL query to:

 PREFIX rdf:   <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
 PREFIX dbpedia:   <http://dbpedia.org/ontology/>
 DESCRIBE ?x where {?x rdf:type dbpedia:Drug} LIMIT 100

In fact, dereferencing a URI is (very often) translated into a SPARQL query by the server. The query usually has the form of:

 DESCRIBE <URI>
