Pharmacology of Lepana
- A molecules of the topical preparations can penetrate the skin by three routes through
- Intact stratum corneum.
- Sweat glands.
- Sebaceous follicles.
- The surface of the stratum corneum presents more than 99 % of the total skin surface available for percutaneous drug absorption.
- The major steps involved in percutaneous absorption include the establishment of a concentration gradient which provides the driving force for drug movement across the skin, release of drug from the vehicle and drug diffusion across the layers of the skin.
- Preferable characteristics of topical drugs include low molecular mass (600da) adequate solubility in oil & water and a high partition co-efficient.
According to the Laws of Diffusion
J = C k D/x
- J = Rate of absorption
- C = Concentration of Drug in vehicle (Amalaki churna)
- K = Partition coefficient (Takra)
- D = Duffusion coefficient (Skin)
- X = Thickness of stratum corneum
According to absorption Theory
- The hydration status of the skin is a to absorption of the external applications
- Increase in the water content of the stratum corneum increases the absorption of the topicals applied
- The mechanism of drug of action is stimulated when it enters the peripheral circulation through sub cutaneous blood vessels.
- Abhyanga over the head using Dhanavantara taila which helps in increase of cutaneous circulation and opening of sweat glands. Thus helps in Pharmacodynamics of the drug.
Amalaki indiacated in:
- Anti atherosclerotic activitiy.
- Phyllembblin acts as an antagonist.
Eranda patra : It is vatahara, covering of lepa with this leaf, increases the hydration of the skin and thus helps in the absorption.
Dhanvantara Taila: It is kept in the small pit at the centre of the crown maintains the body temperature and protects the marma.
- Shiras is Uttamanga, Marmasthana, Pranayatana & Indriyasthana.
- Kapha samsrusta vata dosha, Tiryakgata raktapitta & Marmabhighata can cause various Neurovascular disorders.
