Chlortalidone, also known as chlorthalidone, is a thiazide-like diuretic drug used to treat high blood pressure, swelling including that due to heart failure, liver failure, and nephrotic syndrome, diabetes insipidus, and renal tubular acidosis. Because chlortalidone is reliably effective in most patients with high blood pressure, it is considered a preferred initial treatment. It is also used to prevent calcium-based kidney stones. It is taken by mouth. Effects generally begin within three hours and last for up to three days. Chlortalidone is more effective than hydrochlorothiazide for prevention of heart attack or stroke.Common adverse effects include low blood potassium, low blood sodium, high blood sugar, dizziness, and erectile dysfunction. Other adverse effects may include gout, low blood magnesium, high blood calcium, allergic reactions, and low blood pressure. Some reviews have found chlortalidone and hydrochlorothiazide to have a similar risk of adverse effects, while other reviews have found chlortalidone to have a higher risk. While it may be used in pregnancy it is a less preferred option. How it works is not completely clear but is believed to involve increasing the amount of sodium and water lost by the kidneys.Chlortalidone was patented in 1957 and came into medical use in 1960. It is on the World Health Organizations List of Essential Medicines. It is available as a generic medication. In 2019, it was the 135th most commonly prescribed medication in the United States, with more than 4 million prescriptions. Medical use
High blood pressure
Chlortalidone is considered a first-line medication for treatment high blood pressure.
Warty dyskeratoma, also known as an Isolated dyskeratosis follicularis,: 777  is a benign epidermal proliferation with distinctive histologic findings that may mimic invasive squamous cell carcinoma and commonly manifests as an umbilicated (Having a central mark or depression resembling a navel) lesion with a keratotic plug, WD have some histopathologic similarities to viral warts but its not caused by HPV and the majority of these lesions display overall histopathologic features consistent with a follicular adnexal neoplasm. Usually limited to the head, neck, scalp or face and vulva. Lesions are generally solitary and sporadic and may be associated with a follicular unit. Oral involvement, particularly the hard palate, and genital involvement have been reported. it can also be thought of as one of the manifestations of focal acantholytic dyskeratosis, an epidermal reaction pattern that can be seen in several disorders, including Dariers disease and Grovers disease. : 639  But the main Difference between Darier disease and Warty dyskeratoma, is that Darier disease inherited dermatosis (autosomal dominant) consisting of multiple keratotic papules on the face, trunk, and extremities, while WD occurs as an isolated, noninherited, single keratotic nodule mainly confined to the head and neck as mentioned earlier. Differential Diagnosis
Warty dyskeratoma must be differentiated from vulvar dysplasia, Bowenoid papulosis, squamous carcinoma, condyloma, and other viral-induced squamous lesions. See also
