Andolast is a small molecule activator of Calcium-activated potassium channels and an inhibitor of IgE-mediated anaphylaxis. Andolast is under investigation as an anti-asthmatic and for the treatment of COPD.

Isopimaric acid is a widely available tricyclic diterpenoid well represented in the resin of conifers of the genera Pinus, Larix, and Picea. It exhibits interesting biological and pharmaceutical properties such as antimicrobial, antiviral, antiallergenic, and anti‐inflammatory activities. It acts as a large conductance Ca2+activated K+ channel (BK channel) opener. BK channel openers have emerged as potentially useful agents in the therapy of various diseases associated with both the central nervous system and smooth muscle system.

Cholesterol is a sterol (a combination steroid and alcohol) and a lipid found in the cell membranes of all body tissues, and transported in the blood plasma of all animals. The high level of cholesterol in the blood is a marker of hypercholesterolemia, also called dyslipidemia. As a part of homeopathic product, it helps to support general liver and gallbladder health, and is used for temporary relief of symptoms related to adrenal glands such as fatigue and low energy. Cholesterol binds to and affects the gating of a number of ion channels such as the nicotinic acetylcholine receptor (nAChR) Inwardly-rectifying K+ channels (Kir); Transient receptor potential vanilloid 1 channels (TRPV1) and Large-conductance Ca2+-sensitive voltage-gated K+ channels (BK). It was shown the new mechanistic insights into the role of cholesterol in the regulation of nAChR, showing that cholesterol regulates the channels by two distinct mechanisms: stabilization of the channels in a resting state that depends on specific lipid-protein interactions and facilitation of the transitions between uncoupled and coupled states that depends on the hydrophobic thickness of the membrane

Bendroflumethiazide (INN), formerly bendrofluazide (BAN) is a thiazide diuretic used to treat hypertension. CORZIDE (Nadolol and Bendroflumethiazide Tablets) for oral administration combines two antihypertensive agents: CORGARD (nadolol), a nonselective beta-adrenergic blocking agent, and NATURETIN (bendroflumethiazide), a thiazide diuretic-antihypertensive. Bendroflumethiazide works by inhibiting sodium reabsorption at the beginning of the distal convoluted tubule (DCT). Bendroflumethiazide inhibits active chloride reabsorption at the early distal tubule via the Na-Cl cotransporter, resulting in an increase in the excretion of sodium, chloride, and water. Thiazides like bendroflumethiazide also inhibit sodium ion transport across the renal tubular epithelium through binding to the thiazide sensitive sodium-chloride transporter. This results in an increase in potassium excretion via the sodium-potassium exchange mechanism. The antihypertensive mechanism of bendroflumethiazide is less well understood although it may be mediated through its action on carbonic anhydrases in the smooth muscle or through its action on the large-conductance calcium-activated potassium (KCa) channel, also found in the smooth muscle. Thiazides do not affect normal blood pressure. Onset of action of thiazides occurs in two hours and the peak effect at about four hours. Duration of action persists for approximately six to 12 hours. Thiazides are eliminated rapidly by the kidney.
