Question
Could you please tell me the correct capitalization of the drug "regular insulin"? Is it Regular Insulin, Regular insulin, or regular insulin? It is very confusing. A Google search shows Novo Nordisk as its manufacturer.Answer
Capitalization of Regular/regular varies from one author (or organization) to another, so no wonder you're perplexed. The word "insulin" isn't capitalized.Regular insulin is a form of short-acting insulin, usually lasting less than 8 hours, nowadays usually of synthetic human origin, but also of beef or pork origin.
Regular is sold by all insulin companies: by Novo Nordisk as Regular Human Insulin (Novolin R) (human) and other names; by Eli Lilly as Humulin R (human), Regular Iletin II (purified pork), and Regular Insulin (animal source); and (in Europe and many other parts of the world) by Aventis as Insuman rapid (human).
It is not the fastest-acting insulin, as the insulin analogs Humalog (insulin lispro, from Lilly), Novolog (insulin aspart, from Novo Nordisk), and Apidra (insulin glulisine, from Aventis) all work faster, and don't last quite as long.
