Dual shot injection molding is a type of injection molding that uses two or more different plastic materials or colors to form a single part. The materials can be thermoplastics, thermosets, elastomers, or combinations of these. The process involves injecting the first material into a mold cavity, then transferring the molded part to a second ...

and that such use should be closely moni-tored and documented.2-4 Use of a single LAIA is recommended when the patient prefers the formulation or to avoid treat-ment nonadherence; however, treatment guidelines do not address the simultaneous use of 2 LAIAs.2,4-6 A few case reports have described successful use of dual LAIAs (Table 1,7 …
