Effects on calcium metabolism
In patients treated with both calcipotriol/betamethasone dipropionate (Cal/BD) ointment on the body and Cal/BD topical suspension on the scalp (n=35), 1 patient (2.9%) had elevated urinary calcium levels after 4 weeks of treatment.Three studies of Cal/BD topical suspension have evaluated treatment effects on calcium metabolism. In 2 of the 3 trials (n=32 and n=43), elevated urinary calcium levels outside the normal range were observed in 2 patients each. In the third trial (n=109), no clinically relevant changes in urinary calcium were reported.Potential effects on calcium metabolism have been evaluated in three randomized, multicenter, prospective, vehicle- and/or active-controlled trials of the foam formulation enrolling 564 adults with plaque psoriasis. The foam was applied once daily for four weeks. In these trials, three subjects had serum calcium levels elevated above the upper limit of normal. Urinary calcium elevations above normal were reported in 17 subjects.In a published multicenter, open-label, single-arm trial of the foam formulation, 35 adults with plaque psoriasis applied the foam once daily to all lesions on the trunk, limbs, and scalp for four weeks. No elevations of serum calcium, urinary calcium, or the ratio of urinary calcium to creatinine above the upper limit of normal were observed. History
The combination was developed by LEO Pharma. To combine them, new non-aqueous non-alcohol formulations had to be found to avoid mutual degradation of the two active substances while also achieving the desired skin absorption.
History of phalanges
Etymology
The term phalanx or phalanges refers to an ancient Greek army formation in which soldiers stand side by side, several rows deep, like an arrangement of fingers or toes. In animals
Most land mammals including humans have a 2-3-3-3-3 formula in both the hands (or paws) and feet. Primitive reptiles usually had the formula 2-3-4-4-5, and this pattern, with some modification, remained in many later reptiles and in the mammal-like reptiles. The phalangeal formula in the flippers of cetaceans (marine mammals) varies widely due to hyperphalangy (the increase in number of phalanx bones in the digits). In humpback whales, for example, the phalangeal formula is 0/2/7/7/3; in pilot whales the formula is 1/10/7/2/1.In vertebrates, proximal phalanges have a similar placement in the corresponding limbs, be they paw, wing or fin. In many species, they are the longest and thickest phalanx ("finger" bone). The middle phalanx also a corresponding place in their limbs, whether they be paw, wing, hoof or fin. The distal phalanges are cone-shaped in most mammals, including most primates, but relatively wide and flat in humans. Primates
The morphology of the distal phalanges of human thumbs closely reflects an adaptation for a refined precision grip with pad-to-pad contact. This has traditionally been associated with the advent of stone tool-making.
