Preparations
Drug trade names include Propecia and Proscar, the former marketed for male pattern baldness (MPB) and the latter for benign prostatic hyperplasia (BPH), both are products of Merck & Co. There is 1 mg of finasteride in Propecia and 5 mg in Proscar. Merck's patent on finasteride for the treatment of BPH expired on June 19, 2006. Merck was awarded a separate patent for the use of finasteride to treat MPB. This patent is set to expire in November 2013.
Some studies have shown that the dose of finasteride needed to treat male pattern baldness may be smaller than 1 mg. Petitions to the FDA to re-examine the approved dosage in light of the statistical evidence and possible long-term risks, were met with the response that a study had shown increased effect of a 1 mg dose compared to 0.2 mg without added risks; the same study also concluded that doses of 0.01 mg per day were found to be ineffective in treating hair loss.

Famous quotes containing the word preparations:
“At the ramparts on the cliff near the old Parliament House I counted twenty-four thirty-two-pounders in a row, pointed over the harbor, with their balls piled pyramid-wise between them,—there are said to be in all about one hundred and eighty guns mounted at Quebec,—all which were faithfully kept dusted by officials, in accordance with the motto, “In time of peace prepare for war”; but I saw no preparations for peace: she was plainly an uninvited guest.”
—Henry David Thoreau (1817–1862)
“Whatever may be the reason, whether it was that Hitler thought he might get away with what he had got without fighting for it, or whether it was that after all the preparations were not sufficiently complete—however, one thing is certain: he missed the bus.”
—Neville Chamberlain (1869–1940)
“In all the important preparations of the mind she was complete; being prepared for matrimony by an hatred of home, restraint, and tranquillity; by the misery of disappointed affection, and contempt of the man she was to marry. The rest might wait. The preparations of new carriages and furniture might wait for London and the spring, when her own taste could have fairer play.”
—Jane Austen (1775–1817)
